Wireguard Site to Site Multi-WAN Failover Question

[tman222]

Hi all,

I have two sites connected via Wireguard VPN tunnel, let's call them site 1 and site 2, with their respective IP addresses mapped to site1.tld and site2.tld domains. Site 1 is a Multi-WAN setup in fail-over configuration. Should WAN1 fail on site 1, it will switch automatically over to WAN2 and the site1.tld domain will be mapped to the WAN2 IP address (via dynamic DNS configuration). For the Wireguard tunnel between sites 1 and 2 to switch over to WAN2 if WAN1 fails on site 1, is there anything else I have to do besides ensuring that Wireguard traffic can pass on both WAN1 and WAN2 interfaces on site 1? Since this is a failover configuration, there is no need to configure a second Wireguard interface, correct?

Thanks in advance for your help.
