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.
I just did this dance because mullvad stopped port forwarding for their customers. I ended up using airvpn because I can forward ports in their website console and then connect using my router. Works fine and relatively inexpensive. Proton was on my list, but it was quite a bit more expensive.
I guess you are behind a CGNAT that’s why you want to connect to your VPN using the protonvpn connection instead of your normal ISP?
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.
You should be able to do both. Either configure your routing rules to allow your mobile VPN traffic to go out to the Internet without going over protonvpn, or if you have control over the protonvpn endpoint, install your mobile VPN server there.
