I’ve got a GWN7000 with dual wan. Failover works ok, the two connections are setup blended so, well, it’s working. Both connections are unstable due to specific issues with the ISP’s (DSL way out in the sticks and Starlink).
I’d like to setup DDNS but, it seems I can only set up on one interface (wan) or the other.
Wan 1 has a static IP address and Wan 2 (starlink) is dynamic. Is there a way to set this up so the firewall will updated dydns.org with the wan 1 IP address when running and the wan 2 IP address when wan 1 is down?
