I have a Pi, running Raspbian 10 Buster. I would like to portforward VNC and transmission. I have opened the ports in my router, firewall. The ports are still "closed". I was trying to see why is this, so what I see if I check my wireless interface's MAC address in terminal, it shows different than the one the router sees. I have no idea how this is possible. I'm looking for help. (By the way I run a VPN client on my Pi.) The port is open on the VPN provider side. I use Windscribe, if that matters.
