Our RV340 is connected to two ISPs for redundancy. Each ISP had supplied us with a modem (actually a simple consumer grade wireless router) that is configured to work as a NAT.
The router is connected to both modems receiving addresses 22.214.171.124 and 126.96.36.199 from their built in DHCP servers and serving using its own DHCP server the range 10.100.101.x to the internal LAN.
The problem is that the router fails to detect when one of the WAN links fail since the link to the modem is always on. Is there any way to make the router "ping" a remote address or similar to reliably detect WAN failure?
The two modems cannot work in "bridge" mode and are controlled by the ISPs.
