No shit the VPN requires an open port, I never said otherwise, but if your router is the one running the server, you aren’t forwarding the port. The router itself is listening on its WAN interface.
The VPN prevents you from having to forward any ports, because the router allows you to tunnel in. The only open port will be whatever port the VPN server listens on, and it isn’t a forwarded port.

We literally have a global rise in violent fascism and multiple ongoing genocides, and TikTok is the worst thing you can think of?
