Nov 26, 2015 · The SonicWALL TZ500 comes equipped with optional integrated 802.11ac wireless, IPSec and SSL VPN, failover through integrated 3G/4G support, load balancing and network segmentation, all of which combine advanced networking features with advanced security to boast a pretty impressive package.
When using multiple WANs, a primary and secondary VPN can be configured to allow seamless, automatic failover and failback of all VPN sessions. Route-based VPN The ability to perform dynamic routing over VPN links ensures continuous uptime in the event of a temporary VPN tunnel failure, by seamlessly re-routing traffic between endpoints through When using multiple WANs, a primary and secondary VPN can be configured to allow seamless, automatic failover and failback of all VPN sessions. Route-based VPN The ability to perform dynamic routing over VPN links ensures continuous uptime in the event of a temporary VPN tunnel failure, by seamlessly re-routing traffic between endpoints through Microsoft Azure and SonicWALL STS - Part 2 – Configure SonicWALL OS VPN policy. Microsoft Azure and SonicWALL STS - Part 3 – Configure VPN policies and Routing. Extending the on-premises infrastructure to Azure, the obligatory need is to create site-to-site VPN to access resources in both side. Dead Peer Detection (page 6 of 6) of the IPSec VPN configuration) determines failover/failback time The default failover time is 115 seconds (Connection Idle Time + (Request Period x Maximum Request)) The default failback time is 10 seconds (Failback Retry Period) 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. The configuration tasks on the High Availability > Monitoring page are performed on the Primary unit and then are automatically synchronized to the Secondary. After a failover to the Backup appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. The failover applies to loss of functionality or network-layer connectivity on the Primary SonicWall. When using multiple WANs, a primary and secondary VPN can be configured to allow seamless, automatic failover and failback of all VPN sessions.

Your WAN failover configuration should then take over the burden of reestablishing the VPN during an ISP outage. For your failover settings, make sure you're probing something on the internet and not simply monitoring layer 2 link since an ISP failure is rarely local to your next-hop router. P.S. - Netti, I think we used to work together! level 3
On the Network| WAN Failover & Load Balancing page, under WAN Interface Monitoring, check the Enable Probe Monitoring box. Check the Respond to Probes box to have the SonicWall respond to TCP probes received on its WAN ports. Check the Any TCP-SYN to Port box to respond to TCP probes to the specified port number without validating them. SonicWall's SSL VPN features provide secure remote access to the network using the NetExtender client.NetExtender is an SSL VPN client for Windows or Linux users that is downloaded transparently and that allows you to run any application securely on the company's network. It uses Point-to-Point Protocol (PPP). On the remote SonicWALL (SWsecondary), edit the VPN policy and then put the primary IP in (should already be in), then add the secondary IP (new WAN IP from the main site). This will complete the failover setup.
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. The configuration tasks on the High Availability > Monitoring page are performed on the Primary unit and then are automatically synchronized to the Secondary.
To manage the remote SonicWALL through the VPN tunnel, select HTTP, HTTPS, or both from Management via this SA. Select HTTP, SSH, HTTPS, or any combination of the three in the User login via this SA to allow users to login using the SA. •
