My customer has a RV320 at two locations with both dual WAN's (in Fallback mode) via different Service Providers (see the attached configuration). VPN between the two locations works fine but we have tried all possible settings to setup the Fallback for a VPN connection between these locations but we cannot get it to work. What should be the proper VPN settings to achieve this?
Note: Fallback from one location to two locations is no problem. The problem concerns VPN Fallback in both directions from one to two.
