I have a public IPv6 address, but non-public IPv4, therefore I wanted to access home services from outside via IPv6. I configured the WireGuard VPN server. If I connect from the home network, the VPN works, but I'm not able to connect from outside there. I enabled the ping from WAN and that works. Then I tried to connect to SSH of my home computer. I enabled the port 22 for IPv6 and my global home computer IPv6 address, but no success. Any idea what could be wrong? I'm connected via PPPoE. IPv6 connections from the home network to the world work.
