Hello, I have recently upgraded from 22.03 to 23.05 and my port forwarding from VPN interface to LAN stopped working. While diagnosing, I have set up port forwarding from WAN to LAN, which works, but VPN => LAN does not. Here are my configs:

Is there a reason you added your WireGuard2 interface on 2 Firewall zones?

Found the issue: it was actually caused by the vpn client on another device, using another client resolved this
