Pfsense dynamic DNS service and WAN fallover


I was looking at the dynamic DNS service in pfsense, and noticed that you need to specify the interface that the service checks on

Can’t seem to see option were the service will update using WAN2 if WAN1 goes offline?

(goal is to create a cname DNS entry at domain host, so that all services will fallover to the second WAN2 IP seemlessly)


I don’t have a WAN failover, but don’t the two WANs go into a Gateway Group? If so the interface ought to be the Group and not the WAN interface. If it’s not something like that then I can’t see how it would work.

k, just saw tom’s excellent vid on gateway groups… created one and it shows up as an option in dynamic dns settings :slight_smile:
