I’m using protonvpn setup in my router for all outgoing traffic. Works great but I can’t find anything about opening a port in the vpn without using the app which I can’t do because it’s setup in my router. This is preventing me from using my incoming VPN to connect to my network when I’m away from home.
You may need to reach out to your VPN provider’s support to check if that is a supported feature. Many VPN providers with port forward support can only do it within their application.
