WireGuard Site-to-Site VPN and backup path for dual WAN
-
I set up a WireGuard S2S VPN, everything works well, now I want to handle a situation where one of the ISPs is having a problem (primary site is dual wan, secondary site is single wan).
I set up a 2nd separate tunnel (which uses wan2 at the primary site), this seems to be working - both tunnels are UP, but because I am using static routing, when wan1 is down, the 2nd tunnel is not used. The only solution is to use dynamic routing or is there another approach ?
