We have a Sonicwall TZ205 that has a vpn connection to a Private Verizon network over a hard line internet connection.

If the VPN tunnel fails we want the LAN traffic rerouted to another WAN interface which is directly connected to the Private Verizon network with a cellular modem.

We want this route to active if the VPN tunnel fails and then route the traffic back to the VPN once it is active.

I have looked at a few online answers and have succeeded in rerouting in case of a VPN failure but the traffic will not route back to the VPN once it is active again.

Has anyone experienced this?

The Sonicwall is using SonicOS Enhanced

Thank you!


You had to use tunnel-based VPN and set the appropriate route inside Network->Routing table. For more information, consults the Administration Manual.
