Maybe one day ProtonVPN will fix their port-forwarding for their configuration files, I haven’t seen anyone else complain about this and their support is oblivious that this function even exists.
For people wondering the Learn More link just tells you what port forwarding does.
I mean I’ll give it a try, their support flat out said they don’t support port forwarding for WireGuard configs which is why I never used the feature, but if it’s truly using UPnP than it may be worth a shot!
Edit: https://protonvpn.com/support/port-forwarding-manual-setup#wireguard looks promising!
