Wireguard setup: is this Port Forwarding that causes issues?

[admon]

Hi

@waves

( “the IP address from DDNS domain resolution is not the same as the WAN IP of the device. You need an Internet Public IP address to use Dynamic DNS”) but I proceeded anyway.

That is almost what happens here. Since the router cannot see the WAN IP, it can’t register this IP against the DDNS service. Use https://dnschecker.org/ against your DDNS address to see if it resolves to the right IP.

Make sure to read this note here:

Dynamic DNS not working

Hey NAT isn’t the main problem. The main problem is, that the GL router isn’t able to see the public IP - because it’s behind another router. In that case, it does not know about the public IP and can’t update the DDNS. Only ways to go: Removing the first router in front of the GL one or set it into bridge mode. Using another DDNS service from the first router or some device that offers a service like this Being behind another router and using DDNS does not work with GL DDNS.
