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 5.8.1.13-1o.
Thank you!
