It doesn't matter if "Services from GL.iNet Use VPN" is toggled or not. When Wireguard-VPN is active always the VPN-IP-address will be used for DDNS-Link.
Expectation is, that when function is not toggled the provider-ip is used for DDNS.
I also guess this worked in older versions.
Thanks for the hint.
Installed 4.8.0 beta: if "Services from GL.iNet Use VPN" is not selected the provider ip is used -> as expected.
If "Services from GL.iNet Use VPN" is selected still the provider ip is used -> should it be that way??
This issue is not reproduced in my AX1800 v4.8.0, please disable and re-enable the GL DDNS when it enabled "Services from GL.iNet Use VPN" or disabled, and check again.
