Can you show the diff with your previous WG config?

I didn’t have a previous WG config. This is really the problem: I didn’t change anything. It just stopped working. My phone connects to the server and I can ping it, and I’m also able to use the web interface on the server, but I can’t connect to any other host on the network.

This makes me think it’s a problem with the NAT

This is my assumption too. Still looking into it.
