I am setting up a RUT955 (running 6.5.1) with a main Mobile WAN and failover Wired WAN. I need to always access the device over the Mobile WAN and access the Wired WAN when it's available. This is because I have 2 IPSEC VPN configured and for each VPN to work, I need those 2 WAN interfaces active.
When I disable failover, I can access the device on 4G, over the Mobile WAN. When I enable failover and select the Wired WAN as failover, I can't access the Teltonika over the Mobile WAN.
