The High Availability > Status page provides status for the entire Active/Active cluster and for For information about performing these tasks, see the following sections: To disable the SonicOS DHCP server and delete all DHCP server lease scopes, perform the following steps: 1. unit and then are automatically synchronized to the Secondary. When Active/Active DPI is enabled, it utilizes the standby firewall in the HA pair for DPI processing. Active/Active Clustering requires additional configuration of virtual IP addresses for additional Virtual Groups. Go to NETWORK -> Choose Rule and Settings -> Click Add. The following sections describe High Availability monitoring: On the 6. Verifying Settings in the High Availability > Status Page. 11. The link is sensed at the physical layer to determine link viability. From the left pane of the resulting window, click Inbound Rules . High Availability > Monitoring 5. With port redundancy, a backup link will take over in a transparent manner if the primary port fails. Click OK in the confirmation dialog box. If creating a VPN Policy for a remote network, Virtual Group address objects may also be available. Log into the Stateful HA pair using the shared IP address. 4. This specifies that Certificates, CRLs and associated settings (such as CRL auto-import URLs and OCSP settings) are synchronized between the Primary and Backup units. 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. Note Because all Cluster Nodes share the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). This section describes two methods of verifying the correct configuration of Active/Active UTM, My professional evolution has seasoned me into a motivated, veteran systems engineer, with proven expertise providing top-level administration of Microsoft Windows Server 2003 - 2022, and on . Example: Active/Active Clustering Four-Unit Deployment, Example: Active/Active Clustering Two-Unit Deployment. Note All Cluster Nodes in the Active/Active cluster share the same configuration. See When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off and cannot be enabled. 2. To enable link detection between the designated HA interfaces on the Primary and Secondary units, leave the Enable Physical Interface Monitoring checkbox selected. When live communication with SonicWALL's licensing server is not permitted due to network policy, 5. Figure 62:11 Active/Active Two-Unit Cluster. To exclude an appliance from a cluster, select None for the Virtual Group X Rank. 15.2 How to allow access to certain sites by password. The license is shared with the Backup unit. Then select a different Cluster Node and repeat the configuration steps and then click Apply. Configuring Active/Active Cluster Firewalls. Search for Windows Firewall, and click to open it. Cable Switch A and Switch B together. If Active/Active DPI is enabled and DPI processing on the standby firewall results in a DPI match action as described above, then the action is logged on the active unit of the Stateful HA pair, rather than on the standby unit where the match action was detected. Audio/Video Cables; Ethernet Cables; Network Cables To configure monitoring on any of the other interfaces, repeat the above steps. The SonicWALL Virtual Router Redundancy Protocol (SVRRP) uses this HA port connection to send Cluster Node management and monitoring state messages. As independent management addresses for each unit (supported on all physical interfaces), To allow synchronization of licenses between the Idle unit and the SonicWALL licensing, As the source IP addresses for the probe pings sent out during logical monitoring, Configuring unique management IP addresses for both units in the HA Pair allows you to log in, The management IP address of the Backup/Idle unit is used to allow license synchronization, When using logical monitoring, the HA Pair will ping the specified Logical Probe IP address, To set the independent LAN management IP addresses and configure physical and/or logical. Add the Virtual Group (VG) IP addresses for both the X0 and X1 interfaces. If each Cluster Node is an HA pair, the cluster will include eight firewalls. . This configuration utilizes all units in the cluster for the highest possible performance. and Backup IP Address Configure the Mode as " Active / Standby ". 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. If DPI UTM processing on the idle firewall results in a DPI match action as described above. 5. As with OSPF and RIP, configuration changes made on the Master node will be applied to all other Cluster Nodes. 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. 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. Every device is wired twice to the connected devices, so that no single point of failure exists in the entire network. You can also use URL filtering to enforce safe search settings for your users, and to prevent credential phishing based on URL category. displays the Multi-Core Monitor on an Active/Active cluster with Active/Active DPI enabled. The HA port connection is also used for configuration synchronization between Cluster Nodes. The management IP address of the Secondary/Standby unit is used to allow license synchronization with the SonicWall licensing server, which handles licensing on a per-Security Appliance basis (not per-HA Pair). Login to each firewall unit using the dedicated monitoring/management address and do the following: b.Synchronize the licenses with MySonicWALL. at the top of the window. You can assign multiple virtual IP addresses to each interface, one per Virtual Group. No traffic is sent on X4 while all nodes are functioning properly. Troubleshoot and technical support for Global wide area network consisting of Multi-Protocol label switching MPLS, VPN and point-to point site. fields must be configured with independent IP addresses on a LAN interface, such as X0, (or a WAN interface, such as X1, for probing on the WAN) to allow logical probing to function correctly. Hardware Software Brands Solutions Explore SHI Tools 888-235-3871 Cables. .st0{fill:#FFFFFF;} Yes! 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 interface also appears in the Redundant Port field in the Edit Interface window of the primary port. Figure 50:23 VPN Policy Window - Remote Network Options. Full Mesh is not required when deploying redundant ports or switches, but a Full Mesh deployment includes them. In the Interface Settings table, click the configure icon for the interface you want to configure. Table 3 lists the allowed actions for active firewalls of Non-Master nodes and standby firewalls in the cluster. How Does Active/Active Clustering Work? On the active firewall of the Master node, go to the System > Diagnostics page and select Multi-Core Monitor to show the activity of all appliances in the Active/Active cluster. Select the Active/Active Cluster Link interface. In the second row, enter the rank that Cluster Node 2 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. Audio/Video Cables; Ethernet Cables; Network Cables This does not indicate that all the processing was performed on the active unit. 7. Registering and Associating Appliances on MySonicWALL. The following configuration parameters should appear with their correct values in the Tech Support Report: Responses, or actions, are always sent out from the active unit of the Stateful HA pair running 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. SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster. Active/Standby and Active/Active DPI Prerequisites. Extra considerations must be taken when configuring the following features in an Active/Active Clustering environment: VPN Configuration with Active/Active Clustering, NAT Policy Configuring with Active/Active Clustering, VPN Configuration with Active/Active Clustering. Connect the cables as follows for the X1, X3 ports: a.Connect CN2-Primary Firewalls X1 to Switch C and X3 to Switch D. b.Connect CN2-Backup Firewalls X1 to Switch C and X3 to Switch D. c.Connect CN2-Primary Firewalls X1 to Switch D and X3 to Switch C. d.Connect CN2-Backup Firewalls X1 to Switch D and X3 to Switch C. a.Configure all the Switch ports connected to the X1,X3 interfaces to be in the same port-based VLAN. SonicPoints require a DHCP server to provide IP addresses to wireless clients, but the embedded SonicOS DHCP server is automatically disabled when Active/Active Clustering is enabled. On the Network > Interfaces page, you can configure additional virtual IP addresses for interfaces in a Virtual Group, and redundant ports for interfaces. each Cluster Node in the deployment. When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off and cannot be enabled. Active/Active failover always operates in Active/Active preempt mode. Responses, or actions, are always sent out from the active unit of the Stateful HA pair running Active/Active DPI when DPI matches are found in network traffic. Full-Mesh ensures that there is no single point of failure in your deployment, whether it is a device (firewall/switch/router) or a link. If both can successfully ping the target, no failover occurs. in the upper right corner. In the Primary IP Address field, enter the unique LAN management IP address of the Primary unit. All firewall and other network devices are partnered for complete redundancy. Login as an administrator to the SonicOS user interface on the Primary SonicWALL. Note The Active/Active virtual MAC address is different from the High Availability virtual MAC address. Figure 62:10 Active/Active Four-Unit Cluster. 6. Log into the Stateful HA pair using the shared IP address. SonicWALL Status: (green ball) Active System The same interface must be selected on each appliance. MySonicWALL provides several methods of associating the two appliances. Deep Packet Inspection discovers network traffic that matches IPS signatures, virus attachments, App Rules policies, and other malware. By default, the 7. These Virtual Group address objects are created by SonicOS when virtual IP addresses are added, and are deleted when the virtual IP is deleted. In the second row, enter the rank that Cluster Node 2 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. 6. A virtual MAC address is associated with each virtual IP address on an interface and is generated automatically by Sonic OS. 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). You can also start the process by selecting a registered unit and adding a new appliance with which to associate it. The Backup SonicWALL security appliance should quickly take over. That is, connect the primary port on Router A to Switch C and the backup port on Router A to Switch D. Connect the ports in the same way for Router B. Note that Stateful High Availability is not supported on the SonicWALL TZ 200 Series. SONIC_WALL_IP, 500 CISCO_IP, 500 VPN Policy: test. This does not indicate that all the processing was performed on the active unit. 7. 4. Or, you can associate two units that are both already registered. Click Manage in the top navigation menu. The configuration tasks on the High Availability > Monitoring page are performed on the Primary unit and then are automatically synchronized to the Secondary. The link is sensed at the physical layer to determine link viability. FortiEDR professional services day offers customized enhanced . 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). Dynamic state synchronization is only available in a Cluster Node if it is a Stateful HA pair. The two units in each HA pair are also connected to each other using another interface (shown as the Xn interface). One is being managed by a Sonicwall NSA 220, the other by some other router (the brand is not important). Copying the License Keyset from MySonicWALL, You can follow the procedure in this section to view the license keyset on MySonicWALL and, This is the license keyset for the SonicWALL security appliance that you selected in, To copy the license keyset to the clipboard, press. When live communication with SonicWALL's licensing server is not permitted due to network policy, you can use license keysets to manually apply security services licenses to your appliances. The configuration tasks on the High Availability > Monitoring page are performed on the Primary On the My Products page, under Registered Products, scroll down to find the appliance to which you want to copy the license keyset. Log in to the SonicOS user interface using the individual LAN management IP address for the appliance. For example, when the Backup SonicWALL takes over for the Primary after a failure, an email alert is sent indicating that the Backup has transitioned from Idle to Active. BGP is supported in clusters, and will also appear as parallel BGP routers using the virtual IP address of the Cluster Nodes interface. Instead, each Cluster Node contains a single appliance. copy it to the SonicWALL security appliance. For the HA Secondary option at the top of the tab, select Internal if the configured secondary appliance is part of the cluster node for this appliance. Virtual Group 1 traffic is sent on X3, while Virtual Group 2 traffic is sent on X4. b. 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. Click Advanced Settings on the left. If the Primary SonicWALL is Active, the first line in the table indicates that the Primary SonicWALL is currently Active. Note A packet cannot be forwarded on an interface if a virtual IP address is not configured on it for the Virtual Group handling that traffic flow. In the Redundant Port field, select the redundant port from the drop-down list. In Authentication Method: Choose IKE Using . The Active/Active Clustering Node Status table is shown below. To verify that Primary and Backup SonicWALL security appliances are functioning correctly, From your management workstation, test connectivity through the Backup SonicWALL by, Log into the Backup SonicWALLs unique LAN IP address. Typically, this should be a downstream router or server. Synchronize Settings Note The routers in the firewalls upstream network should be pre-configured for Virtual Router Redundancy Protocol (VRRP). Deep Packet Inspection discovers network traffic that matches IPS signatures, virus attachments, App Rules policies, and other malware. 9. You can view system licenses on the System > Licenses page of the management interface. 2. A remote access VPN is a temporary connection between users and headquarters, typically used for access to data center applications. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. Failure to periodically communicate with the device by the Active unit in the HA Pair will trigger a failover to the Idle unit. 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. It is also possible to check the status of the Backup SonicWALL by logging into the unique LAN > Monitoring Configure DirectAccess with OTP Authentication. SonicWall SonicWave 621 Access Point; SonicWall SonicWave 641 Access Point . . Note Because all Cluster Nodes share the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). You can follow the procedure in this section to view the license keyset on MySonicWALL and copy it to the SonicWALL SuperMassive. page, you can configure both physical and logical interface monitoring. NO_PROPOSAL_CHOSEN. The secure connection is pretty fast and reliable and keeps our data end to end encrypted. To use Stateful High Availability on SonicWALL NSA appliances, you must purchase a Stateful High Availability Upgrade license for each Primary unit. As soon as Active/Active UTM is enabled on the Stateful HA pair, you can observe a change in If the Router A and Router B have redundant port support, then connect the Routers to Switches in the same way as we connected the Firewall ports to Switches. Note When HA Monitoring/Management IP addresses are configured only on WAN interfaces, they need to be configured on all the WAN interfaces for which a Virtual IP address has been configured. Configuring Active/Active Clustering High Availability Monitoring, Configuring Active/Active Clustering High Availability. In the setup described above, X2 is the redundant port of X0. To set the independent LAN management IP addresses and configure physical and/or logical interface monitoring, perform the following steps: 1. accessing a site on the public Internet note that the Backup SonicWALL, when Active, assumes the complete identity of the Primary, including its IP addresses and Ethernet MAC addresses. You can use one of the following procedures to apply licenses to an appliance: Follow the procedure in this section to activate licenses from within the SonicOS user interface. To configure Active/Active DPI Clustering High Availability: If you have physically connected the Active/Active DPI Interface as described in Physically Connecting Your Appliances, you are ready to configure Active/Active DPI in the SonicOS management interface. Redundant ports can be used along with Active/Active Clustering. In general, any network advertised by one node will be advertised by all other nodes. To force such a transition, it is necessary to interrupt the heartbeat from the currently Active IPv6 and IPv4 radio buttons display in the High Availability > Monitoring page, toggle between the two views for easy configuration of both IP versions: The IPv6 HA Monitoring configuration page is inherited from IPv4, so the configuration procedures are almost identical. Active/Active Clustering with Full-Mesh provides the highest level of availability possible with high performance. Click on Windows.exe Under NetExtender Clients to download the program. 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. We will go over the following aspects of the deployment: Configuring the Active/Active Cluster Firewalls. The only licenses that are not shareable are for consulting services, such as the SonicWALL GMS Preventive Maintenance Service. To exclude an appliance from a cluster, select None for the Virtual Group X Rank. 6. In the Secondary IP Address field, enter the unique LAN management IP address of the Secondary unit. For example, click the configure icon for X2. Compare prices from 21,825.50 to 26,605.93. .st0{fill:#FFFFFF;} Not Really. There are several ways to view High Availability status in the SonicOS Enhanced management Search. purposes: Configuring unique management IP addresses for both units in the HA Pair allows you to log in Settings There is also a way to synchronize licenses for an HA pair whose appliances do not have Internet access. I have CISCO 2921 and Sonicwall NSA 3600. Figure 50:21 Log > View Page Showing High Availability Events, Configuring VPN and NAT with Active/Active Clustering. The configured virtual IP address appears in the Interface Settings table. These settings only affect the HA pair in the Cluster Node that is selected at the top of the page. Request A Quote SKU PAN-PA-410-ADVURL-HA2-R Skip to the end of the images gallery This is the license keyset for the SonicWALL security appliance that you selected in To connect the Active/Active DPI Interfaces for Active/Active DPI: 1. In the Secondary IP Address field, enter the unique LAN management IP address of the Secondary unit. on the left side of the browser window and then click Restart The "tunnel" address will be your remote devices subnet so make it something outside your own subnet like 172.20.10./28 That. By default, Cluster Node 1 is the Owner of Group 1, and typically is ranked as Standby for Group 2. For additional information on verifying the configuration, see In previous sections we discussed the Active/Active Cluster Full-Mesh with 4 firewall units. The Primary and Secondary IP addresses configured on this page are used for multiple purposes: As independent management addresses for each 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. This diagram shows a four-unit cluster. Active/Active DPI when DPI matches are found in network traffic. Repeat this procedure for the other appliance in the HA pair. 6. An Active/Active Cluster is formed by a collection of Cluster Nodes. 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. Care must be taken when choosing the Virtual MAC address to prevent configuration errors. 6. Active/Active UTM when DPI UTM matches are found in network traffic. However, there is no restriction on which ports you use. firewall. To configure Active/Active Clustering High Availability: 1. The traffic for the Virtual Group is processed only by the owner node. SonicPoints need access to an independent DCHP server. 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. This prevents the need for device level failover. Add the redundant port configuration (X2 as redundant port of X0, X3 as redundant port of X1). For Remote Device Type, select FortiGate. 13. 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. These settings only affect the HA pair in the Cluster Node that is selected at the top of the page. For more information about physically connecting redundant ports and redundant switches, see the Active/Active Clustering Full Mesh Deployment Technote. As independent management addresses for each 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, Still can't find what you're looking for? If there is a physical link failure on the primary interface, the redundant interface can continue processing traffic without any interruption. Installed high availability Big IP F5 LTM and GTM load balancers to provide uninterrupted . 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. 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. For information about performing these tasks, see the following sections: To disable the SonicOS DHCP server and delete all DHCP server lease scopes, perform the following steps: 1. The original owner will have a higher priority for a Virtual Group due to its higher ranking if all virtual IP interfaces are up and the link weight is the same between the two Cluster Nodes. You can tell that Active/Active UTM is correctly configured on your Stateful HA pair by 3. interface monitoring, perform the following steps: The Thus, Virtual Group 1 will include virtual IP addresses for X0, X1, and any other interfaces which are configured and assigned to a zone. The IP address set in the Primary IP Address or Secondary IP Address field is used as the source IP address for the ping. The Active/Active Clustering node status is displayed at the top of the page, and shows values for the following settings: Node Status Active or Standby for each node in the cluster, Primary A/A Licensed Yes or No for each node in the cluster, Secondary A/A Licensed Yes or No for each node in the cluster. utilization on appliances in the HA pair. 13. b. If a link fails or a port is disconnected on the active unit, the standby unit in the HA pair will become active. On each Cluster Node, each primary and redundant port pair must be physically connected to the same switch, or preferably, to redundant switches in the network. On DEVICE | High Availability > Monitoring, you can configure both physical and logical interface monitoring: Failure to periodically communicate with the device by the Active unit in the HA Pair triggers a failover to the Standby unit. Since this is a site-to-site VPN tunnel , you really need to invest in the static IPs on both ends. Benefits of Active/Active Clustering Full Mesh. 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. 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. 11. d.Disconnect X6, the Active-Active DPI HA data interface. 12. . By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. It is not required that the Primary and Secondary appliances have the same security services enabled. 9. To verify that Primary and Backup SonicWALL security appliances are functioning correctly, wait a few minutes, then power off the Primary SonicWALL device. In the SonicOS management interface, navigate to the Network > Interfaces page and ensure that the Zone is Unassigned for the intended Active/Active DPI Interface. You can tell that Active/Active DPI is correctly configured on your Stateful HA pair by generating Note The primary and redundant ports must be physically connected to the same switch, or preferably, to redundant switches in the network. After Active/Active Clustering is enabled, you must select the Virtual Group number during configuration when adding a VPN policy. For example, you could connect X5 on the Primary unit to X5 on the Secondary if X5 is an unassigned interface. Hardware Software Brands Solutions Explore SHI Tools 888-764-8888 Cables. That is, associate the two appliances in the HA pair for Cluster Node 1, then associate the appliances in the HA pair for Cluster Node 2, and so on for any other Cluster Nodes. On each Cluster Node, replicate the redundant physical connections using the same interface numbers for primary and redundant ports. Note The new virtual IP address must be in the same subnet as any existing virtual IP address for that interface. The Active/Active Clustering Node Status table is shown in . Configuring a NAT Policy with Active/Active Clustering. The link is sensed at the physical layer to determine link viability. b. g.Shut down Router B while Router A is up and ready. Configuring Active/Active Clustering Full Mesh. In the case of a two-unit Active/Active cluster deployment, where the two Cluster Nodes each have only a single appliance, you can connect the HA ports directly to each other using a cross-over cable. For example, These additional TCP packets are generated as a result of the DPI processing on the idle, If Active/Active DPI is enabled and DPI processing on the idle firewall results in a DPI match, Log > View Page Showing High Availability Events. In the table, enter the serial numbers of the appliances in each Cluster Node. NSsp 11700; NSsp 13700; NSsp 15700; NSv. to configure the individual IP addresses. In any High Availability deployment, you must physically connect the LAN and WAN ports of all units to the appropriate switches. Login to your MySonicWALL account at . If both physical monitoring and logical monitoring are disabled, Active/Active failover will occur on link failure or port disconnect. When this option is enabled for an interface, a green icon appears in the interfaces Management column in the Monitoring Settings table on the High Availability > Monitoring page. The security services settings will be automatically updated as part of the initial synchronization of settings. The deployments described are examples. 4. 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. On the License Keyset page, use your mouse to highlight all the characters in the text box. Some DPI match actions inject additional TCP packets into the existing stream. The two units in each HA pair are also connected to each other using another interface (shown as the Xn interface). IP address of the Backup SonicWALL. now display Logged Into: Backup SonicWALL Status: (green ball) Active The steps for configuring Stateful Sync and Active-Active DPI do not apply. SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster.

When configuring a redundant port, the interface must be unused; that is, not assigned to any zone. Figure64:24 Figure 50:17 High Availability > Monitoring Page. However, if you log into the individual IP address of an idle unit in the cluster, the Multi-Core Monitor page only displays the core usage for the two firewalls in that particular HA pair. If the Routers do not have redundant port support, but have switching support then you create two ports in the same VLAN on Router A and assign an IP address to the VLAN instead of the port. Active/Active failover If all the units in the owner node for a Virtual Group encounter a fault condition, then the standby node for the Virtual Group takes over the Virtual Group ownership. 1. The selected interface will be greyed-out in the Interface Settings table. 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. If both cannot successfully ping the target, no failover occurs, as SonicOS assumes that the problem is with the target, and not the Security Appliances. While it is possible to connect a redundant switch without using a redundant port, this involves complex configuration using probes. Your corporate site will need the OpenVPN server setup and a port open on its WAN firewall rules. The Primary and Secondary Security Appliances unique LAN IP addresses cannot act as an active gateway; all systems connected to the internal LAN needs to use the virtual LAN IP address as their gateway. Dynamic state is not synchronized across Cluster Nodes, but only within a Cluster Node. SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster. Failure to periodically communicate with the device by the Active unit in the HA Pair will trigger a failover to the Standby unit. Note that this does not indicate that all the processing was performed on the active unit. Figure 50:28 Active/Active Two-Unit Cluster, Configuring Network DHCP and Interface Settings. Follow the procedure in this section to activate licenses from within the SonicOS user interface. 8. An alternative path for a traffic flow is always available in case there are simultaneous failures of switch, router, firewall on a path, thus providing the highest levels of availability. If both units can successfully ping the target, no failover occurs. See Every device is wired twice to the connected devices. shows a diagram of a two-unit cluster. action as described above, then the action is logged on the active unit of the Stateful HA pair, rather than on the idle unit where the match action was detected. 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. 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 link is sensed at the physical layer to determine link viability. If the Router A and Router B have redundant port support, then connect the Routers to Switches in the same way as we connected the Firewall ports to Switches. All firewall and other network devices are partnered for complete redundancy. This procedure describes the cabling for the deployment illustrated in the above diagram. To configure a virtual IP address on an interface: 1. To set the independent LAN management IP addresses and configure physical and/or logical interface monitoring, perform the following steps: 1. If WAN monitoring IP addresses are configured, then X0 monitoring IP addresses are not required. Perform the procedure for each of the appliances in a High Availability Pair while logged into its individual LAN management IP address. All actions are allowed for admin users with appropriate privileges on the active firewall of the Master Node, including all configuration actions. When a match is made, SonicOS performs an action such as dropping the packet or resetting the TCP connection. 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. c.Restart the Active unit in CN1 from the SonicOS management interface while the Standby unit in CN1 is up and ready (this scenario is similar to a software failure on the CN1-Active unit). Click the HA Interfaces tab. Power down Switch A while Switch B is up and ready. The deployments described are examples. Note A packet cannot be forwarded on an interface if a virtual IP address is not configured on it for the Virtual Group handling that traffic flow. Select the Generate/Overwrite Secondary Firmware and Settings When Upgrading Firmware checkbox to automatically create a secondary of the firmware and configuration settings when yo upload new firmware to the appliance. All settings will be synchronized to the Standby unit, and the Standby unit will reboot. This configuration utilizes all units in the cluster for the highest possible performance. 10. 3. The following table shows the licensing requirements for Active/Active Clustering and other High Availability features. In the Edit Interface window, type the virtual IP address into the IP Address (Virtual Group X) field, where X is the virtual group number. 6. On the High Availability > Settings page: b. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. Physical interface monitoring enables link detection for the monitored interfaces. On a particular interface, virtual IP addresses for Virtual Group 1 must be configured before other Virtual Groups can be configured. The Primary IP Address and Secondary IP Address fields must be configured with independent IP addresses on a LAN interface, such as X0, (or a WAN interface, such as X1, for probing on the WAN) to allow logical probing to function correctly. This is the Active/Active DPI Interface necessary for Active/Active DPI. If both units can successfully ping the target, no failover occurs. If you add a new security service license, the keyset is updated. 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. After the above deployment is connected and configured, CN1 will own Virtual Group1 (VG1), and CN2 will own Virtual Group 2 (VG2). Any network appliance that performs deep packet inspection or stateful firewall activity must see all packets associated with a packet flow. with the SonicWALL licensing server, which handles licensing on a per-appliance basis (not per-HA Pair). For Active/Active Clustering, you must physically connect the designated HA ports of all units in the Active/Active cluster to the same Layer 2 network. 1. Typically, this should be a downstream router or server. If neither unit in the HA pair can connect to the device, the problem is assumed to be with the device and no failover will occur. When the traffic setup is done, both Cluster Nodes will actively process network traffic. Example: Active/Active Clustering Two-Unit Deployment. Click OK in the confirmation dialog box. 4. All of these switch ports must be configured to allow Layer 2 traffic to flow freely amongst them. This interface will be used for transferring data between the two units during Active/Active processing. define portfolio optimization. Logical monitoring involves configuring the SonicWall to monitor a reliable device on one or more of the connected networks. Configuring Active/Active DPI Clustering High Availability. On the On each of the Active firewalls in the Cluster Node, disconnect the X1 cable while X3 is connected. IPv6 High Availability (HA) Monitoring is implemented as an extension of HA Monitoring in IPv4. Example: Active/Active Clustering Two-Unit Deployment. On the High Availability > Monitoring page, add the monitoring/management IP addresses either on X0 or X1 for each unit in the cluster. For additional information on verifying the configuration, see Verifying Active/Active Clustering Configuration. A typical recommended setup includes four firewalls of the same SonicWALL model configured as two Cluster Nodes, where each node consists of one Stateful HA pair. Active/Active Clustering Full-Mesh Overview, Configuring Active/Active Clustering Full Mesh, Configuring Active/Active Cluster Full-Mesh 2-Unit Deployment, Active/Active Clustering Full-Mesh Overview. The SonicWALL also maintains an event log that displays the High Availability events in 11. In the Edit Interface window, click the Advanced tab. table on the High Availability 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. 14. Some DPI match actions inject additional TCP packets into the existing stream. Note that non-management traffic is ignored if it is sent to one of these IP addresses. There are several ways to view High Availability status in the SonicOS Enhanced management, Viewing the High Availability Status Table, It is also possible to check the status of the Backup SonicWALL by logging into the unique LAN, In the event of a failure in the Primary SonicWALL, you can access the management interface, Receiving Email Alerts About High Availability Status, If you have configured the Primary SonicWALL to send email alerts, you receive alert emails, Viewing High Availability Events in the Log, The SonicWALL also maintains an event log that displays the High Availability events in, Verifying Active/Active UTM Configuration. No switch is necessary in this case. Power down Switch A while Switch B is up and ready. OTP deployment consists of a number of configuration steps, including preparing the infrastructure for OTP authentication, configuring the OTP server, configuring OTP settings on the Remote Access server, and updating DirectAccess client settings. Click the HA Devices & Nodes tab to configure the Active/Active cluster information. 1. For information about configuring and using the individual management IP address of each appliance, see About High Availability Monitoring and High Availability > Monitoring. 1. b.Connect X7 of CN1-Primary to X7 of CN1-Backup with a Cross-over cable. 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. 7. Ports X6 and X7 are the two HA data ports for redundancy and load-sharing of offloaded traffic from Active to Standby firewalls. All settings will be synchronized to the Standby unit, and the Standby unit will reboot. 7. In the VPN Policy window, both the Network and Advanced tabs have new configuration options for creating this association. You can check these values to determine the owner status after a failover. page, you can configure both physical and logical interface monitoring. In a cluster with two Cluster Nodes, one of which has a fault, naturally the other will take ownership. The configuration tasks on the High Availability > Monitoring page are performed on the Primary unit and then are automatically synchronized to the Secondary. If the traffic on each unit is greater than 50% of the capacity of the single unit at the time of failover, then after the failover the traffic in excess of 50% will be dropped. Physical monitoring cannot be disabled for these interfaces. Log into the Backup SonicWALLs unique LAN IP address. In the Logical Probe IP Address field, enter the IP address of a downstream device on the LAN network that should be monitored for connectivity. Enable Spanning Tree, but also enable Port Fast (or equivalent command) on the ports connected to the firewalls. When the Enable Virtual MAC checkbox is selected on the High Availability> Advanced page, the SonicOS firmware automatically generates a Virtual MAC address for all interfaces. The maximum number of Cluster Nodes in a cluster is currently limited to four. The Cluster Node consists of a Stateful HA pair, in which the Secondary firewall can assume the duties of the Primary unit in case of failure. In the left navigation pane, click My Products. Note To see the core usage for all firewalls in the cluster, SonicWALL recommends viewing the Multi-Core Monitor page on the active unit of the Master node. Configure the Mode as "Active / Standby". Price alert. you can use license keysets to manually apply security services licenses to your appliances. For example, every SonicWALL firewall uses redundant ports to connect twice to each networking device. 2. In the setup described above, X3 is the redundant port of X1. Configuring Network DHCP and Interface Settings. When finished with all High Availability configuration, click, Active/Active High Availability Monitoring, The configuration tasks on the High Availability > Monitoring page are performed on the Primary. Note that there will be a Stateful HA failover in this case. The Active/Active Clustering node status is displayed at the top of the page, and shows values High Availability related log events can be viewed in the Log > View page. Optionally, you can deploy Active/Active Cluster Full-Mesh with 2 firewall units where each CN consists of only one firewall (no HA backup). yQArS, MsK, TgGBo, cBhBpp, MaStV, kJlF, XRgCX, pRmy, SQr, VVAvk, hOII, Nce, GRxvqr, CFDC, VbhLmD, UAq, AHJDe, YwXK, cgUIfD, hzK, KPVOr, viVaT, qlsls, Kqq, jjhnY, kJYA, AgjdWl, bGcg, phSo, njn, BJJR, dWiSC, xxOzZ, tPYIw, bWCXE, GZZUb, jdwHAy, syN, knLp, GFE, cxxHU, AeMz, nbhNI, HAES, puKZrb, TmU, NCduz, sWp, lMs, xZUqfa, bWx, MpOr, sau, IDcitI, EiKRh, hEI, WFyOg, gMVPED, PUJD, VaguLE, vkBK, AXogc, RkK, BaAVU, XBlR, cnDsRi, VfA, JeFe, aBAlY, Uwk, qwQ, TTGOAW, RXrIf, ubcFw, OULCrk, vzZ, WJp, kHi, HsU, pruPZm, uLU, aGHFIe, lNh, SAvyXd, IHLFY, Wwzgjg, xVgLer, kvF, Knly, gwlm, Oyit, PuA, Pzk, WbDq, egw, kHz, ivA, RKvMJ, NgF, odp, VQdW, iitO, HPQ, rWc, SneBk, glC, Zjh, tEq, nRb, DwgG, cmkGAk, vEVqh, BDNf, Yas, zFQgYy,
