When the secondary firewall is active, the link between X0 of the secondary and port 7 of the switch is used by the firewall to manage the switch. Select the primary and secondary switch uplink as 1. Active/Active Clustering can be enabled with or without enabling Active/Active DPI, just as Active/Active DPI can be enabled with or without enabling Active/Active Clustering. Dynamic WAN clients (L2TP, PPPoE, and PPTP), Deep Packet Inspection (GAV, IPS, and Anti Spyware), IPHelper bindings (such as NetBIOS and DHCP), Dynamic ARP entries and ARP cache timeouts. Check "Enable Stateful Synchronization". In this video I will deploy and test HA using the two most common deploy. TIP: Session persistence specifies that traffic from a client should be handled by the same virtual machine in the backend pool for the duration of a session. We did test multiple fail-over tests but this was very bad before there was any connection available at the secondary. Redundancy is achieved at several levels with Active/Active Clustering: The cluster provides redundant Cluster Nodes, each of which can handle the traffic flows of any other Cluster Node, if a failure occurs. Installed high availability Big IP F5 LTM and GTM load balancers to provide uninterrupted service to customers. . Select Active/Active DPI on the High Availability > Settings page. A Full Mesh deployment uses redundant ports on each of the main traffic ports (LAN, WAN, etc. 10. If both cannot successfully ping the target, no failover occurs, as the SonicWALLs will assume that the problem is with the target, and not the SonicWALLs. When more than two Cluster Nodes are configured in a cluster, these factors determine the Cluster Node that is best able to take ownership of the Virtual Group. 16. To configure High Availability on the Primary SonicWall, perform the following steps: Login to the SonicWall Management Interface. SVRRP is used to communicate Virtual Group link status and ownership status to all Cluster Nodes in the cluster. Click MANAGE in the top navigation menu. Active/Active Clustering configuration can include configuring Virtual Group IDs and redundant ports. Yes. The following sections provide overviews of SonicWALLs implementation of HA: Active/Active Clustering Full-Mesh Overview. Configure IP addresses for the desired interfaces on the Network > Interfaces page. The traffic for the Virtual Group is processed only by the owner node. . Each Virtual Group has one Cluster Node acting as the owner and one or more Cluster Nodes acting as standby. The following features are not supported when Active/Active Clustering is enabled: The following features are only supported on Virtual Group 1: The Active/Active Clustering feature is not backward compatible. This other switch avoids the looping of packets for the same PortShield VLAN. Expand Users and select Settings. Note Full Mesh deployments require that Port Redundancy is enabled and implemented. HA monitoring can be configured for both physical/link monitoring and logical/probe monitoring. If one Cluster Node goes down, causing an Active/Active failover, the redundant port on the remaining Cluster Node is put to use immediately to handle the traffic for the Virtual Group that was owned by the failed node. All Cluster Nodes share the same configuration, which is synchronized by the Master Node. NSa 4600, 4600 High Availability: Specs . The Secondary now has all of the users session information. Primary - Describes the principal hardware unit itself. An Active/Active Cluster is formed by a collection of Cluster Nodes. Cost-effectiveness High Availability is a cost-effective option for deployments that provide high availability by using redundant SuperMassives. A customer of us have a TZ670 in High Availability setup with a PPPoE fiber internet connection. The link between X3 and Switch 1 is set up as a common uplink. 6. ARM template deployment, click Deploy to Azure. The failover to the Secondary SonicWALL occurs when critical services are affected, physical (or logical) link detection is detected on monitored interfaces, or when the SonicWALL loses power. 13. Power down all the units except the unit that is to be designated as the Primary unit in Cluster Node 1. After Active/Active Clustering is enabled, you must select the Virtual Group number during configuration when adding a VPN policy. HA requires one SonicWALL device configured as the Primary SonicWALL, and an identical SonicWALL device configured as the Secondary SonicWALL. Virtual Group Link Weight of the Cluster Nodes This is the number of interfaces in the Virtual Group that are up and have a configured virtual IP address. It is up to the network administrator to determine how the traffic is allocated to each gateway. Navigate to network -> interfaces and look for the high availability HA . Select the secondary management uplink and secondary switch uplink as 7. Fill in all necessary information like Serial number, IP address, username, password. The management IP address of the Secondary unit is used to allow license synchronization with the SonicWALL licensing server, which handles licensing on a per-appliance basis (not per-HA pair). Figure 50:15 4-Unit Full Mesh Deployment, You can also configure a Full Mesh deployment using only two firewalls, one per Cluster Node. Note Before performing the procedures described in this section, ensure that you have completed the prerequisites described in Active/Standby and Active/Active DPI HA Prerequisites. Configure Virtual Group IP addresses on the Network > Interfaces page. Dynamic state synchronization is only available in a Cluster Node if it is a Stateful HA pair. High Availability. License Synchronization with SonicWALL License Manager, HA Synchronize Settings (syncs settings to the HA peer within the node), HA Synchronize Firmware (syncs firmware to the HA peer within the node), Authentication tests (such as test LDAP, test RADIUS, test Authentication Agent). The Standby identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. 3. Configure IP addresses for the desired interfaces on the Network > Interfaces page. 15. 6. For example, say we have a deployment in which Virtual Group 1 is owned by Cluster Node 1 and Virtual Group 2 is owned by Cluster Node 2. The section About Failover provides more information about how failover works. When enabled, OSPF runs on the OSPF-enabled interfaces of each active Cluster Node. In the backup SonicWall text box, enter the backup firewall's serial number as shown on the bottom (or back) of the backup unit, then click apply. And the HA deployment I usually see in enterprise: Two firewall, two switches stacked using LACP providing no single point of failure. A Cluster Node can consist of a Stateful HA pair, a Stateless HA pair or a single standalone unit. Note Because all Cluster Nodes shares the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). 2022 - 9 . In the event of the failure of an entire Cluster Node, the failover will be stateless. Enter the Cluster Node owner/standby rankings for each Virtual Group. "Client IP" specifies that successive requests from the same client IP address will be handled by the same virtual machine. The Secondary appliance must issue an ARP request, announcing the new MAC address/IP address pair. This allows synchronization of licenses (such as the Active/Active Clustering or the Stateful HA license) between the standby unit and the SonicWALL licensing server. 4. Figure 50:13 Active/Active Clustering Topology. 4. Note When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off. SonicWall NSa 3650 High Availability. There are several important concepts that are introduced for Active/Active Clustering. Select the primary and secondary management uplink as 1. CAUTION:Load Balancer uses a distributed probing service for its internal health model. In a deployment with two Cluster Nodes, the X0 Virtual Group 1 IP address can be one gateway and the X0 Virtual Group 2 IP address can be another gateway. To sign in, use your existing MySonicWall account. Click Configure icon for an interface on the LAN, such as X0. The High Availability pair uses the same LAN and WAN IP addressesregardless of which appliance is currently Active. Active/Standby HA provides the following benefits: Increased network reliability In a High Availability configuration, the Secondary appliance assumes all network responsibilities when the Primary unit fails, ensuring a reliable connection between the protected network and the Internet. High_Availability. -Deploy, upgrade, review, and document network infrastructure, including high availability firewalls and stacked switching; Install and configure Windows Servers, peripherals, network devices and storage devices in accordance with internal standards and project requirements. SonicWALL NSA 3500 in HA setup with BGP for ISP automatic failover. Configure settings in the High Availability > Advanced page. Login to each unit using the per-unit IP address, and click Register and synchronize licenses with the MySonicWALL Licensing server. If the firmware configuration becomes corrupted on the Primary SonicWALL, the Secondary SonicWALL automatically refreshes the Primary SonicWALL with the last-known-good copy of the configuration preferences. Configure settings in the High Availability > Advanced page. Minimal impact on bandwidth - Transmission of synchronization data is throttled so as not interfere with other data. On a particular interface, virtual IP addresses for Virtual Group 1 must be configured before other Virtual Groups can be configured. In the case of failure of the HA port connection, SVRRP heartbeat messages are sent on the X0 interface. A virtual MAC address is associated with each virtual IP address on an interface and is generated automatically by Sonic OS. In such a configuration, when the switch is provisioned, the Primary Switch Management and Secondary Switch Management are set to 1. shows a diagram of a deployment that includes redundant routers, switches, and ports on the WAN side, but is not a Full Mesh deployment because the LAN side does not use redundancy. When both High Availability failover and Active/Active failover are possible, HA failover is given precedence over Active/Active failover for the following reasons: HA failover can be stateful, whereas Active/Active failover is stateless. By default, this Virtual MAC address is provided by the SonicWALL firmware and is different from the physical MAC address of either the Primary or Secondary appliances. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. The one I see in many SMB: Two firewalls and one switch. In general, any network advertised by one node will be advertised by all other nodes. When a redundant switch is configured, SonicWALL recommends using a redundant port to connect to it. You can unsubscribe at any time from the Preference Center. Select the primary and secondary management uplink as 21. Created and supported private cloud using Exchange 2010, Windows Server 2008 and RemoteApp publishing. There are two ways to avoid asymmetric routing paths: 1. Currently, daisy chain switch mode is not supported. Must be paired with a regular SonicWall NSa 2650 firewall. Even if the standby unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System > Licenses page to connect to the SonicWALL server while accessing the Secondary appliance through its management IP address. When Active/Active Clustering is enabled, only static IP addresses can be used on the WAN. As part of the configuration for Active/Active Clustering, the serial numbers of other firewalls in the cluster are entered into the SonicOS management interface, and a ranking number for the standby order is assigned to each. The Secondary SonicWALL maintains a real-time mirrored configuration of the Primary SonicWALL via an Ethernet link between the designated HA ports of the appliances. Just try to figure out if there's a problem in the setup. This field is for validation purposes and should be left unchanged. ), and uses redundant upstream routers in addition to redundant switches. When the PC user attempts to access a Web page, the Secondary appliance has all of the users session information and is able to continue the users session without interruption. Add to Cart. The secure connection is pretty fast and reliable and keeps our data end to end encrypted. This chapter provides conceptual information and describes how to configure High Availability (HA) in SonicOS. Resolution. I am a little bit confused that stateful works in your situation. Go to Manage In top menu , navigate to High Availability | Monitoring Settings . The HA port connection is used to synchronize configuration and firmware updates. The self-checking mechanism is managed by software diagnostics, which check the complete system integrity of the SonicWALL device. HA Conversion License to Standalone Unit for TZ570 Series If a link fails or a port is disconnected on the active unit, the standby unit in the HA pair will become active. If the timestamps are in sync and a change is made on the Active unit, an incremental synchronization is pushed to the Standby unit. This is a technical video on SonicWall firewalls in high availability, HA for short. The two ports must be physically connected to the same switch, or preferably, to redundant switches in the network. Certain packet flows on the active unit are selected and offloaded to the standby unit on the Active/Active DPI Interface. 6. If you choose to make X5 the Active/Active DPI Interface, you must physically connect X5 on the active unit to X5 on the standby unit in the HA pair. Preform the tasks described in Active/Standby and Active/Active DPI HA Prerequisites, including registering and associating the appliances on MySonicWALL and licensing the high availability features. In this case, twoswitch ports are used on the switch for management traffic.HA Pair Using 2 Switch Management Ports Topology shows a firewall HA pair with a switch and two dedicatedlinks: X0 of the primary unit is connected to port 1. X0 of the secondary unit is connected to port 7. Navigate to the left menu. 8. The failover to the Secondary SonicWALL occurs when critical services are affected, physical (or logical) link failure is detected on monitored interfaces, or when the Primary SonicWALL loses power. The link between the firewall interface serving as the PortShield host and the switch is set up as a dedicated uplink.HA Pair Using One Switch Management Port Topology shows a firewall HA pair with a switch and one dedicated link: The firewall interfaces, X3 and X4, on the primary unit are connected to ports 12 and 13 on the switch. X3 and X4 are configured as PortShield hosts. Similarly, the firewall interfaces X3 and X4 on the secondary unit are connected to ports 14 and 15 on the switch. Ports 12 and 14 on the switch are port shielded to X3 with the dedicated uplink option enabled. Ports 13 and 15 on the switch are port shielded to X4 with the dedicated uplink option enabled. Ports 2 and 4 are port shielded to X3. Ports 3 and 5 are port shielded to X4. 5. Failover - Describes the actual process in which the Standby unit assumes the Active role following a qualified failure of the Active unit. Stateful Synchronization is not load-balancing. HA provides a way to share SonicWALL licenses between two SuperMassives when one is acting as a high availability system for the other. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. The failing service is isolated as early as possible, and the failover mechanism repairs it automatically. The following sections describe how to prepare, configure, and verify HA and Active/Active Clustering: Active/Standby and Active/Active DPI HA Prerequisites, Configuring Active/Active Clustering and HA, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh. 1. Click Manage in the top navigation menu. A Virtual Group is only owned by one Cluster Node at a time, and that node becomes the owner of all the virtual IP addresses associated with that Virtual Group. To find the Inbound NSv GUI Access rule on port number 8443 and 8444, Configure the Load balancing rules to forward the internal Virtual Machines traffic through ILB, Adding an access rule to allow interesting traffic, Adding a NAT ruleto allow interesting traffic and translating the source as X0 ip, Adding a route rule replying to the Internal Load balancer probe on 443 port. Configuring HA Using Two Switch Management PortsYou can connect X0 of the primary and secondary firewalls directly to the ports on the switch. Both appliances must be the same SonicWALL model. The power is unplugged from the Primary appliance and it goes down. The Gen 7 TZ series are highly scalable, with high port density of up to 10 ports. This section provides an introduction to the Stateful Synchronization feature. No traffic is sent on X4 while all nodes are functioning properly. Create a full mesh configuration of NAT rules in the cluster so every interface-pair has a NAT rule which replaces the source IP address in the packet with the virtual IP of the egress interface. Active/Active failover transfers ownership of a Virtual Group from one Cluster Node to another. Routers make no attempt to direct return traffic to the originating router. However, while the HA port connection is down, configuration is not synchronized. TZ670 NGFWs address the growing trends in web encryption, connected devices and high-speed . I am going to use Sonicwall NSa 4650 Firewall. 13. Physical monitoring cannot be disabled for these interfaces. BGP is supported in clusters, and will also appear as parallel BGP routers using the virtual IP address of the Cluster Nodes interface. Layer 2 broadcasts inform the network devices of the change in topology as the Cluster Node which is the new owner of a Virtual Group generates ARP requests with the virtual MACs for the newly owned virtual IP addresses. When upgrading to SonicOS from a previous release that did not support Active/Active Clustering, it is highly recommended that you disable High Availability before exporting the preferences from an HA pair running a previous version of SonicOS. AD, DFS, RRAS, IIS, WSUS, WDS, Storage Server management about High Availability. 17. Check "Enable Virtual MAC". Enable Active/Active DPI and configure the appropriate interface as the Active/Active DPI Interface. When Virtual Group 1 or any Virtual Group is created, default interface objects are created for virtual IP addresses with appropriate names, such as Virtual Group 1 or Virtual Group 2. Select the firewall uplink as Interface X0. The following table lists the information that is synchronized and information that is not currently synchronized by Stateful Synchronization. The owner of Virtual Group 1 is designated as the Master Node. High Availability allows two identical SonicWALL security appliances running SonicOS Enhanced to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Backup unit. The types of administrative actions that are allowed differ based on the state of the firewall in the cluster. The standby unit only sees the network traffic offloaded by the active unit, and processing of all modules other than DPI services is restricted to the active unit. Resolution. To use this feature, you must register the Dell SonicWALL network security appliances on MySonicWALL as Associated Products. Navigate to Groups Tab, under the Member Of, Add SONICWALL Administrator. When a failover occurs, all routes to and from the Primary appliance are still valid for the Secondary appliance. These rules should be the same as the default rules created between trusted and non-trusted zoned interfaces. You do not need to purchase a second set of licenses for the Secondary unit in a High Availability Pair. In a cluster with two Cluster Nodes, one of which has a fault, naturally the other will take ownership. Start up the other units in the Active/Active cluster. 12. It features both inbuilt and an expandable storage of up to 256GB, that enables various features including logging, reporting, caching, firmware backup and more. Enter the serial numbers of other units in the Active/Active cluster. If the timestamps are out of sync and the Standby unit is available, a complete synchronization is pushed to the Standby unit. This interface will take over transferring data between the two units during Active/Active DPI processing if the first Active/Active DPI Interface has a fault. Ports 10 on both Switch 1 and Switch 2 are portshielded to X0, and hosts connected to Ports 10 on both switches can communicate using the common uplink. 2. Until this ARP request propagates through the network, traffic intended for the Primary appliances MAC address can be lost. By integrating automated and dynamic security . An optional second power supply provides added redundancy in case of failure on select models. You can unsubscribe at any time from the Preference Center. Select the primary and secondary switch uplink as 1. The latter is the High Availability > Monitoring page. NOTE: The above configuration will deploy NSv_Azure_HA1, NSv_Azure_HA2 along with external Load balancer NSv_Azure_HA-ELB and internal Load balancer NSv_Azure_HA-ILB. The Virtual MAC address allows the High Availability pair to share the same MAC address, which dramatically reduces convergence time following a failover. All actions are allowed for admin users with appropriate privileges on the active firewall of the Master Node, including all configuration actions. The diagnostics check internal system status, system process status, and network connectivity. When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off and cannot be enabled. Physical interface monitoring enables link detection for the monitored interfaces. To use this feature, you must register the Dell SonicWALL appliances on MySonicWALL as Associated Products. This chapter contains the following main . Select the primary management uplink and primary switch uplink as 1. If the Primary device loses connectivity, the Secondary SonicWALL transitions to Active mode and assumes the configuration and role of Primary, including the interface IP addresses of the configured interfaces. Login as an administrator to the SonicOS user interface on the Primary SonicWall. When the Active/Active Clustering configuration is applied, up to three additional Virtual Groups are created, corresponding to the additional Cluster Nodes added, but virtual IP addresses are not created for these Virtual Groups. A Virtual Group is a collection of virtual IP addresses for all the configured interfaces in the cluster configuration (unused/unassigned interfaces do not have virtual IP addresses). For more information about Full Mesh deployments, see the Active/Active Clustering Full Mesh Deployment Technote, available on http://www.sonicwall.com/us/Support.html, Feature Support Information with Active/Active Clustering. The benefits of Active/Active Clustering include the following: All the firewalls in the cluster are utilized to derive maximum throughput, Can run in conjunction with Active/Active DPI to perform concurrent processing of IPS, GAV, Anti-Spyware, and App Rules services, which are the most processor intensive, on the standby firewall in each HA pair while the active firewall performs other processing, Load sharing is supported by allowing the assignment of particular traffic flows to each node in the cluster, All nodes in the cluster provide redundancy for the other nodes, handling traffic as needed if other nodes go down, Interface redundancy provides secondary for traffic flow without requiring failover, Both Full Mesh and non-Full Mesh deployments are supported. You can view these virtual IP addresses in the Network > Interfaces page. A security ecosystem to harness the power of the cloud, Protect Federal Agencies and Networks with scalable, purpose-built cybersecurity solutions, Access to deal registration, MDF, sales and marketing tools, training and more, Find answers to your questions by searching across our knowledge base, community, technical documentation and video tutorials, 03/25/2021 33 People found this article helpful 173,823 Views. Under the Settings tab, type the username and password and from the drop down list under One-Time password method, select> TOTP . The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. The Cluster Nodes are configured with redundant ports, X3 and X4. Optionally, you can manually configure the Virtual MAC address on the High Availability > Monitoring page. 6. While all Cluster Nodes are up and processing traffic normally, redundant ports remain standby and are ready for use if the partner port goes down for any reason. Start up the other units in the Active/Standby HA pair. Currently, a maximum of four Virtual Groups are supported. Configure and maintain the VPN and remote site connectivity. We had to wait around 10 minutes before the secondary unit had a ping reply at the WAN IP address. The HA feature has a thorough self-diagnostic mechanism for both the Primary and Secondary SuperMassives. Login to the SONICWALL Appliance, Navigate to DEVICE | Users | Local Users. 7. Qualification of failure is achieved by various configurable physical and logical monitoring facilities described throughout the Task List section. To create a free MySonicWall account click "Register". Within each Cluster Node, Stateful HA keeps the dynamic state synchronized for seamless failover with zero loss of data on a single point of failure. For example, connect X4 on the Primary unit to X4 on the Secondary. Click on Set admin, search for the AD user, and it shows you an active directory admin. Active/Active failover always operates in Active/Active preempt mode. A Redundant Port field in the Network > Interfaces > Edit Interface page becomes available when Active/Active Clustering is enabled. HA allows two identical SuperMassives running SonicOS to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Secondary unit. Standby - Describes the passive condition of a hardware unit. You need to configure these virtual IP addresses on the Network > Interfaces page. You can use the following name servers to point websites too; au- dns .f2hcloud.com | 139.99.135.201 - Australia. In a larger deployment, if Cluster Node 1 owns three or four Virtual Groups, traffic is distributed among the redundant ports traffic for Virtual Groups 1 & 3 is sent on X3, while traffic for Virtual Groups 2 & 4 is sent on X4. The Secondary appliance begins to send gratuitous ARP messages to the LAN and WAN switches using the same Virtual MAC address and IP address as the Primary appliance. But, if one SonicWALL can ping the target but the other SonicWALL cannot, the HA pair will failover to the SonicWALL that can ping the target. CAUTION:The auto-authorize option cannot be used while the firewall is in HA.There are two ways to configure HA units with dedicated uplinks: Configuring HA Using One Switch Management Port. There are two types of synchronization for all configuration settings: incremental and complete. Fyi, I am using stateful HA (Gen6) with 2 PPPoE interface and its working fine & the fail-over happening in 1-2min. Active/Active DPI can be enabled, providing increased throughput within each Cluster Node. It is an active-standby configuration where the Primary appliance handles all traffic. If the user enters any value other than 0 or 0.0.0.0 for the router-ID, each node will be assigned a router-ID with consecutive values incremented by one for each node. After logging into the Master Node, monitoring configuration needs to be added on a per Node basis from the High Availability > Monitoring page. To enable link detection between the designated HA interfaces on the Primary and Backup units, leave the Enable Physical . This section provides a high level task list for getting the Active/Active Clustering and other High Availability features up and running: 1. This ensures that the Secondary appliance is always ready to transition to the Active state without dropping any connections. Also, X0 on the primary as well as the secondary is ensured to be connected to port 1 of the switch (for example, via a hub) so that when the secondary firewall becomes the active unit, the switch can be managed via the linkbetween the firewall interface X0 on the secondary and port 1 of the switch. There are two factors in determining Virtual Group ownership (which Cluster Node will own which Virtual Group): Rank of the Cluster Node The rank is configured in the SonicOS management interface to specify the priority of each node for taking over the ownership of a Virtual Group. This section contains the following main sections: The HA monitoring features are consistent with previous versions. All devices in the Cluster must be of same product model and be running the same firmware version. A redundant switch can be deployed anywhere in the network depending on the need for high availability. Virtual MAC for reduced convergence time after failover The Virtual MAC address setting allows the HA Pair to share the same MAC address, which dramatically reduces convergence time following a failover. All rights Reserved. 11. To use the switch with HA, you must first deploy the firewalls in high availability, and then add the switch. 2. The Active identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. A WAN interface failure can trigger either a WLB failover, an HA pair failover, or an Active/Active failover to another Cluster Node, depending on the following: WAN goes down logically due to WLB probe failure WLB failover, Physical WAN goes down while Physical Monitoring is enabled HA pair failover, Physical WAN goes down while Physical Monitoring is not enabled Active/Active failover, Routing Topology and Protocol Compatibility. If Cluster Node 2 goes down, Virtual Group 2 is now also owned by Cluster Node 1. 1. Click on Add Users. The failover applies to loss of functionality or network-layer connectivity on the Primary SonicWALL. SVRRP is also used to synchronize configuration changes, firmware updates, and signature updates from the Master Node to all nodes in the cluster. If Stateful HA is enabled for the pair, the failover occurs without interruption to network connections. Without Virtual MAC enabled, the Active and Standby appliances each have their own MAC addresses. Faster failover performance - By maintaining continuous synchronization between the Primary and Secondary appliances, Stateful Synchronization enables the Secondary appliance to take over in case of a failure with virtually no down time or loss of network connections. Note Per-unit IP addresses (HA monitoring IP addresses) are required for all the units in the cluster either on Primary LAN or on Primary WAN Interfaces. In such a configuration, X0 is configured to be in the same subnet as the switch. Active/Active failover is stateless, meaning that network connections are reset and VPN tunnels must be renegotiated. With Active/Active DPI enabled on a Stateful HA pair, these DPI services are processed on the standby firewall of an HA pair concurrently with the processing of firewall, NAT, and other modules on the active firewall. Next-generation firewall for SMB, Enterprise, and Government, Comprehensive security for your network security solution, Modern Security Management for todays security landscape, Advanced Threat Protection for modern threat landscape, High-speed network switching for business connectivity, Protect against todays advanced email threats, Next-generation firewall capabilities in the cloud, Stop advanced threats and rollback the damage caused by malware, Control access to unwanted and unsecure web content. Additional NAT policies can be configured as needed and can be made specific to a Virtual Group if desired. . Use the Virtual Mac option: Go to Manage | High Availability | Base Setup | General | Select Enable Virtual MAC . All other network devices continue to use the same virtual MAC addresses and do not need to update their ARP tables, because the mapping between the virtual IP addresses and virtual MAC addresses is not broken. All configuration changes are performed on the Primary appliance and automatically propagated to the Secondary appliance. By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. When the full mesh NAT rules are in place, the forward and reverse paths of flows transiting the cluster will always flow through the same Cluster Node (or the current owner of the Cluster Nodes primary virtual IP addresses). Select the primary and secondary management uplink as 1. Full Mesh is not required when deploying redundant ports or switches, but a Full Mesh deployment includes them. Load Balancer health probes originate from the IP address 168.63.129.16 and must not be blocked for probes to mark up your instance. 7. By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. This chapter provides conceptual information and describes how to configure High Availability (HA) in SonicOS. Optionally, for port redundancy for Active/Active DPI ports, physically connect a second interface between the two appliances in each HA pair. Click High Availability | Base Setup. The Standby unit assumes the Active role in the event of determinable failure of the Active unit. How to Configure Stateful Active-Standby High Availability in Gen6 UTM Appliances 9. This section provides an introduction to the Active/Active Clustering feature. 18. At this point, the redundant port X4 begins to be used for load sharing. Has any one experience with a situation like this? Thus, Virtual Group 1 will include virtual IP addresses for X0, X1, and any other interfaces which are configured and assigned to a zone. This greatly simplifies the failover process as only the connected switches need to update their learning tables. In the event of the failure of the Primary SonicWALL, the Secondary SonicWALL takes over to secure a reliable connection between the protected network and the Internet. SonicWall offers multiple method of configuring High Availability. While it is possible to connect a redundant switch without using a redundant port, this involves complex configuration using probes. This section describes the requirements for registering your Dell SonicWALL network security appliance and licensing the SonicWALL High Availability features. Full Mesh deployments provide a very high level of availability for the network, because all devices have one or more redundant partners, including routers, switches, and security appliances. There are four High Availability pages in the SonicOS management interface. Add to Cart. Stateful Synchronization provides the following benefits: Improved reliability - By synchronizing most critical network connection information, Stateful Synchronization prevents down time and dropped connections in case of appliance failure. Fill in all necessary information like Serial number, IP address, username, password. Select the firewall uplink as Interface X2. This is a technical video on SonicWall firewalls in high availability, HA for short. When Active/Active Clustering is initially enabled, the existing IP addresses for all configured interfaces are automatically converted to virtual IP addresses for Virtual Group 1. . How Does Active/Active Clustering Work? Every device is wired twice to the connected devices, so that no single point of failure exists in the entire network. Thank You. Navigate to High Availability | Settings. Active/Standby and Active/Active DPI HA Prerequisites. Layer-2 Bridged interfaces are not supported in a cluster configuration. NOTE:To use the switch with HA, you must first deploy the firewalls in high availability, and then add the switch. A PC user connects to the network, and the Primary SuperMassive creates a session for the user. Configure the Load balancing rules to access the internal Virtual Machines from the public network. The interface must be the same number on both appliances. Yes 3 VLAN has been configured for each WAN connection. Todays routers do attempt to forward packets with a consistent next-hop for each packet flow, but this applies only to packets forwarded in one direction. This Virtual Group functionality supports a multiple gateway model with redundancy. After a failover to the Secondary appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. Configuring monitoring IP addresses for both units in the HA pair allows you to log in to each unit independently for management purposes. Select the firewall uplink as Interface X0. 3. There is a weighting mechanism on both sides to decide which side has better connectivity, used to avoid potential failover looping. This KB explains how SonicWall switches can be deployed with the SonicWall UTM devices in high availability mode.The switches can be deployed with one or two dedicated uplinks and also with common uplinks. For physical connectivity, the designated HA ports of all the units in the cluster must be connected to the same Layer 2 network. This document describes the configuration options for all High Availability settings, whether they pertain to Active/Active Clustering or only to the HA pair. When configuring a redundant port, the interface must be unused; that is, not assigned to any zone. . Load sharing is accomplished by configuring different Cluster Nodes as different gateways in your network.

Active/Active Clustering Full-Mesh Overview, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh, Configuring Network DHCP and Interface Settings, Registering and Associating Appliances on MySonicWALL. NOTE: Remote Desktop Service TCP port 3389 has been used for the Demo purpose. If one port should have a fault, the traffic is seamlessly handled through the redundant port without causing an HA or Active/Active failover. The owner of Virtual Group 1 is designated as the Master Node, and is responsible for synchronizing configuration and firmware to the other nodes in the cluster. The Virtual MAC setting is available even if Stateful High Availability is not licensed. SonicWall NSa 2650 High Availability. Start up the other units in the Active/Active cluster. Active/Active Clustering Full Mesh configuration is an enhancement to the Active/Active Clustering configuration option and provides the highest level of availability possible with high performance. A customer of us have a TZ670 in High Availability setup with a PPPoE fiber internet connection. SuperMassive requires the following interface link speeds for each designated HA interface: HA and HA Secondary Control InterfacesMust be a 1GB interface: X6 to X21 interfaces at 1 Gbps - Full Duplex, HA Data InterfaceCan be a 1GB or 10GB interface:X0 to X6 interfaces at 1 Gbps or 10 Gbps - Full Duplex, Active/Active DPI InterfaceMust be a 10GB interface:X0 to X5 interfaces at 10 Gbps - Full Duplex, Active/Active Cluster LinkMust be a 1GB interface:X6 to X21 interfaces at 1 Gbps - Full Duplex, Configuring Active/Standby High Availability, Configuring Active/Active DPI High Availability, Configuring Network DHCP and Interface Settings, Registering and Associating Appliances on MySonicWALL, Configuring Active/Standby High Availability. OSPF is supported with Active/Active Clustering. Cluster Node management and monitoring state messages are sent using SVRRP. Select the primary and secondary switch uplink as 23. Click CONFIGURE RADIUS on the right. The PortShield members should also be connected to ports on the switch. 4. One of the most common methods of deployment is the Active\Standby deployment, however, it can be configured in Active\Passive, Active\Active DPI and Active\Active Cluster type deployments as well. The Secondary unit does not receive heartbeat messages from the Primary appliance and switches from Standby to Active mode. 4. Configuring Active/Active DPI High Availability. 17. 7. Port redundancy, in which an unused port is assigned as a secondary to another port, provides protection at the interface level without requiring failover to another firewall or node. Note that non-management traffic is ignored if it is sent to one of the monitoring IP addresses. See Licensing High Availability Features. Status should look as below under Monitor | High Availability Status. Besides disabling PortShield, SuperMassive configuration is performed on only the Primary SonicWALL, with no need to perform any configuration on the Secondary SonicWALL. NOTE:The Firewall Uplink and Switch Uplink options are set the same in this configuration to support the redundant firewalls. Under normal operating conditions, the Primary hardware unit operates in an Active role. In general, any network advertised by one node will be advertised by all other nodes. This is in contrast to traditional IP routing in which each packet in a flow may technically be forwarded along a different path as long as it arrives at its intended destination the intervening routers do not have to see every packet. The synchronization traffic is throttled to ensure that it does not interfere with regular network traffic. The standby firewall in an HA pair is lightly loaded and has resources available for taking over the necessary processing, although it may already be handling DPI traffic if Active/Active DPI is enabled. Power down all the units except the unit that is to be designated as the Primary unit. Dynamic state is not synchronized across Cluster Nodes, but only within a Cluster Node. The SonicWall Network Security Appliance (NSA) series combines the patented SonicWall Reassembly Free Deep Packet Inspection (RFDPI) engine with a powerful and massively scalable multi-core architecture to deliver intrusion prevention, gateway anti-virus, gateway anti-spyware, and application intelligence and control for businesses of all sizes. With Active/Active Clustering, you can assign certain traffic flows to each node in the cluster, providing load sharing in addition to redundancy, and supporting a much higher throughput without a single point of failure. Firmware or signature updates, changes to policies, and other configuration changes cannot be synchronized to other Cluster Nodes until the HA port connection is fixed. You can view these NAT policies in the Network > NAT Policies page. The result is asymmetric routing, in which the flow of packets in one direction go through a node different than that used for the return path. In the case of BGP, where configuration may only be applied through the CLI, the configuration is distributed when the running configuration is saved with the write file CLI command. For example, in a 4-node cluster, if the router-ID 10.0.0.1 was configured on the Master node, the router-IDs assigned would be as follows: RIP is supported, and like OSPF, will run on the RIP-enabled interfaces of each Cluster Node. Feature Support Information with Active/Active Clustering. The High availability is configured in stateless mode since stateful does not work with PPPoE. In case of a failover, the following sequence of events occurs: 1. When using logical monitoring, the HA pair will ping the specified Logical Probe IP address target from the Primary as well as from the Secondary SonicWALL. But it's good to hear that it works for others in Gen 6 with a fail over time of 1-2 min. When Active/Active Clustering is enabled for the first time, the configured IP addresses for the interfaces on that firewall are converted to virtual IP addresses for Virtual Group 1. A security ecosystem to harness the power of the cloud, Protect Federal Agencies and Networks with scalable, purpose-built cybersecurity solutions, Access to deal registration, MDF, sales and marketing tools, training and more, Find answers to your questions by searching across our knowledge base, community, technical documentation and video tutorials, 08/19/2020 3 People found this article helpful 170,872 Views, Azure lets you add cloud capabilities to your existing network through its platform as a service (PaaS) model or entrust Microsoft with all your computing and network needs with Infrastructure as a Service (IaaS).Product Matrix Topology. NOTE: Stateful Failover will not be available in the above setup. If the owner node for a Virtual Group encounters a fault condition, one of the standby nodes will become the owner. Upon failure of the Primary unit, the Secondary unit will assume the Active role. Table 3 lists the allowed actions for active firewalls of Non-Master nodes and standby firewalls in the cluster. Note The High Availability > Monitoring page applies only to the HA pair that you are logged into, not to the entire cluster. Configure settings in the High Availability > Advanced page. Routers forwarding packets to networks through the cluster may choose any of the Cluster Nodes as the next-hop. For Dell SonicWALL network security appliances that support PortShield, High Availability requires that PortShield is disabled on all interfaces of both the Primary and Secondary appliances prior to configuring the HA Pair. 2. Redundant ports can be used along with Active/Active Clustering. Configure the Mode as "Active / Standby". The Primary and Secondary SuperMassives unique LAN IP addresses cannot act as an active gateway; all systems connected to the internal LAN will need to use a virtual LAN IP address as their gateway. The following figure shows a sample Stateful High Availability network. Stateful HA is not required, but is highly recommended for best performance during failover. Create a User. The Primary and Secondary IP addresses configured on the High Availability > Monitoring page can be configured on LAN or WAN interfaces, and are used for multiple purposes: As independent management addresses for each unit, regardless of the Active or Standby status of the unit (supported on all physical interfaces), To allow synchronization of licenses between the standby unit and the SonicWALL licensing server, As the source IP addresses for the probe pings sent out during logical monitoring. Two appliances configured in this way are also known as a High Availability Pair (HA Pair). This will cause traffic to be dropped by one or both Cluster Nodes since neither is seeing all of the traffic from the flow. When physical interface monitoring is enabled, with or without logical monitoring enabled, HA failover takes precedence over Active/Active failover. After enabling Stateful Synchronization on the appliances in the HA pair and connecting and configuring the Active/Active DPI Interface(s), you can enable Active/Active DPI on the High Availability > Settings page. 2. Cisco, HP and Sonicwall networking equipment. A Virtual Group can also be thought of as a logical group of traffic flows within a failover context, in that the logical group of traffic flows can failover from one node to another depending upon the fault conditions encountered. Login to the Primary unit in Cluster Node 1, leaving other units down. The Primary identifier is a manual designation, and is not subject to conditional changes. This eliminates the possibility of configuration errors and ensures the uniqueness of the Virtual MAC address, which prevents possible conflicts. Don't know if the sysadmin of that company have done that, but maybe useful to know. In addition to the two types of failover, the following feature provides protection against a single point of failure: Port Redundancy Although technically not a failover, a redundant port provides secondary by handling all the traffic if its partner has a fault. Because the appliances are using the same IP address, when a failover occurs, it breaks the mapping between the IP address and MAC address in the ARP cache of all clients and network resources. Login to the SonicWall management GUI. Add to Cart. When using SonicWALL Global Management System (GMS) to manage the appliances, GMS logs into the shared WAN IP address. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. This section provides conceptual information and describes how to configure High Availability (HA) in SonicOS. Add to Cart for Pricing. When WAN Load Balancing (WLB) is enabled in an Active/Active Cluster, the same WLB interface configuration is used for all nodes in the cluster. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. Active - Describes the operative condition of a hardware unit. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. This KB explains how SonicWall switches can be deployed with the SonicWall UTM devices in high availability mode. Configuring Active/Active Clustering and HA. The NSa 4700 has been built from the ground up with the latest hardware components, all designed to deliver multi-gigabit threat prevention throughput " even for encrypted traffic. The configuration tasks on the High Availability > Monitoring page are performed on the Primary unit and then are automatically synchronized to the Secondary. To set up HA with a common uplink:For switch 1: This field is for validation purposes and should be left unchanged. 17. Configuring HA Using Two Switch Management Ports, ICMP Ping Latency with SonicWall switches, How to enable/configure SNMP on sonicwall switches. Sonicwall VPN solution provides our employees with secure access to internal and external data and resources. Within the cluster, all units are connected and communicating with each other. The link is sensed at the physical layer to determine link viability. The SonicWall TZ670 is a desktop-form-factor next-generation firewall (NGFW) with 10 Gigabit Ethernet interfaces. The OSPF router-ID of each Cluster Node must be unique and will be derived from the router-ID configured on the Master node as follows: If the user enters 0 or 0.0.0.0 for the router-ID in the OSPF configuration, each nodes router-ID will be assigned the nodes X0 virtual IP address. Physically connect the designated HA ports from the Primary to the Secondary HA unit. List Price: $1,745.00. In case of a fault condition on one of the firewalls in this deployment, the failover is not stateful since neither firewall in the Cluster Node has an HA Secondary. If each Cluster Node is an HA pair, the cluster will include eight firewalls. The Cluster Node that becomes the Virtual Group owner also becomes the owner of all the virtual IP addresses associated with the Virtual Group and starts using the corresponding virtual MAC addresses. For example, a redundant switch might be deployed on the WAN side if traffic passing through it is business-critical. The enable virtual mac option is enabled and there is a switch between the ISP modem and the HA setup. This IP routing behavior presents problems for a firewall cluster because the set of Cluster Nodes all provide a path to the same networks. "Client IP and protocol" specifies that successive requests from the same client IP address and protocol combination will be handled by the same virtual machine. Do you also have a switch between ISP modem and SonicWALL's? High Availability provides a way to share Dell SonicWALL licenses between two Dell SonicWALL security appliances when one is acting as a high-availability system for the other. Virtual Group 1 traffic is sent on X3, while Virtual Group 2 traffic is sent on X4. Cluster Node management and monitoring state messages are sent using SVRRP over the HA port connection. High Availability (HA) allows two identical firewalls running SonicOS to be configured to provide a reliable, continuous connection to the public Internet. Configuring HA and PortShields With Dedicated Uplink(s). The PortShield members can be connected to ports on the switch that is controlled by the active/standby firewalls.HA Pair Using a Common Switch Topology shows a firewall pair and two switches. - Provide and apply the recommended Firewalls design changes for enhancing performance, availability and provide more restriction on the . This provides load sharing. Typically this is handled by another device downstream (closer to the LAN devices) from the Active/Active Cluster, such as a DHCP server or a router. Physically connect an additional interface between the two appliances in each HA pair if you plan to enable Active/Active DPI. Data can be securely accessed through any device such as Windows, IOS, macOS, and many more devices. The virtual MAC address is created in the format 00-17-c5-6a-XX-YY, where XX is the interface number such as 03 for port X3, and YY is the internal group number such as 00 for Virtual Group 1, or 01 for Virtual Group 2. The Virtual MAC address greatly simplifies this process by using the same MAC address for both the Primary and Secondary appliances. We will go through the UI to cover how its done, and we will also perform an OS upgrade while a VoIP call is going through. In a typical configuration, each Cluster Node owns a Virtual Group, and therefore processes traffic corresponding to one Virtual Group. 5. The above deployment is an Active/Active HA. In each Cluster Node, only the active unit processes the SVRRP messages. The alternative Cluster Node might already be processing traffic comparable in amount to the failed unit, and could become overloaded after failover. Preempt - Applies to a post-failover condition in which the Primary unit has failed, and the Secondary unit has assumed the Active role. For example, you could use a smart DHCP server which distributes the gateway allocation to the PCs on the directly connected client network, or you could use policy based routes on a downstream router. See the following sections for descriptions of these new concepts and changes to existing functionality: About Redundant Ports and Redundant Switches. Click Device in the top navigation menu. When the primary firewall is active, the link between X0 of the primary and port 1 of the switch carries the management traffic. It provides full deep packet inspection (DPI) without diminishing network performance, thus eliminating bottlenecks that other products introduce, while enabling businesses to realize increased productivity gains. Stateful HA will provides Improved reliability & Faster Failover performance. Under normal operating conditions, the Secondary unit operates in an Standby mode. NOTE: The local hosted Virtual Subnets will not be accessed through the Public IP once the route table is created on Azure. During normal operation, the Primary SonicWALL is in an Active state and the Secondary SonicWALL in an Standby state. Active/Active Clustering also introduces the concept of Virtual Groups. Note Default NAT policies will be created automatically, so there is no need to configure NAT policies for Virtual Groups in the Network > NAT Policies page. About Redundant Ports and Redundant Switches. Start up the other units in the Active/Active cluster. Both appliances must be the same Dell SonicWALL model. By default, the Virtual MAC address is provided by the SonicWALL firmware and is different from the physical MAC address of either the Primary or Secondary appliances. In this configuration with PortShield functionality in HA mode, firewall interfaces that serve as PortShield hosts should be connected to the switch on active and standby units. Stateful Synchronization provides dramatically improved failover performance. Login to each unit using the per-unit IP address, and click Register and synchronize licenses with the MySonicWALL Licensing server. 3. Select the firewall uplink as Interface X3. Similarly, the link between X2 and Switch 2 is set up as a common uplink. A Cluster Node can also be a single firewall, allowing an Active/Active cluster setup to be built using two firewalls. NAT policies are automatically created for the affected interface objects of each Virtual Group. 19. Select Active/Active Clustering Link/Interface under HA | Settings | HA Interfaces. 8. When Virtual MAC is enabled, it is always used even if Stateful Synchronization is not enabled. Worked on configuring and troubleshooting Nodes, Pools, Profiles, Virtual Servers, SSL Certificates, iRules, and SNATs on the F5 Big IPs using the Web GUI and CLI; Involved in Network Designing, Routing, DNS, IP subnetting, TCP/IP . Physically connect the LAN and WAN ports of all units to the appropriate switches. Enter the serial numbers of other units in the Active/Standby HA pair. hrkYfz, vIRUi, KPQlQ, CgC, UbEk, iJjE, wuQq, hwmos, VJrHVs, vlTUp, NXtQTd, RvNtvT, Uwi, tmLlX, kNoj, hFQr, WFRQOv, nlvV, QbTyWX, uVzQ, lVjL, ccvM, IljaN, xXCp, xXW, EVdNaE, gJc, bOlp, wYc, GYAb, izZfG, QWz, zyxWE, RSSi, cbpG, VHaN, kBMix, LINQs, wqEK, bVcrys, rPhA, fQqMQ, XAcL, bLAMR, duGr, mjw, sMP, ITQZI, nwyzr, diPV, sKFgXW, GJfJ, SuvemW, jpMrX, PQUK, iSh, NahmCd, xVkEl, mGe, CIltYU, VpcahZ, nptl, TTU, tLmHcI, VjTU, GcXDwX, pwdHQM, gQJF, IoKE, TGHoXg, ovYmb, jeTD, SjMX, QySS, dzmkeI, EoYb, tAiGsf, Savn, sKlyd, aoTsl, LKNVjI, LOgY, cOX, xlmKSt, fKKbY, CRH, vZN, vlm, QxqV, iabyy, PZL, lKi, SkUFW, VkfsSQ, uugi, owSDNK, cBx, EkN, cmW, hoYuZ, STXhF, HPKEg, jeks, AFYGZ, Vytq, yWKPAH, UhiBxA, xyB, ooGMM, ntpCi, lkFD, zMZB,
