Hello, trying to set up a wireguard server (with wg-easy docker container) to access it remotely. I have an Opnsense router behind a T-Mobile home internet gateway, which supposedly blocks inbound traffic via CGNAT and doesn’t allow port forwarding. I am using a free no-ip domain name set up to update to my T-Mobile ip to bypass the no static ip issue. Currently I cannot access my home network from a phone running the wg-tunnel app with the tunnel enabled, either from inside or outside the network, despite allowing UDP traffic to/from the server on port 51820 via the router.

Research online suggests that people have gotten this setup working with wireguard, and perhaps it could be as simple as switching to ipv6 for wireguard. Since I’m pretty new to this, I’m not sure exactly how to set this up and whether that’s all I need to do or if additional steps are involved. Specifically, not certain whether I need to set up ipv6 on the wireguard docker container or the server itself, or both. Has anyone gotten something like this working?
