I run through a VPN, they allow me to set up a random port forward, but it uses different ports for wan vs lan.
Example: my external port that is open is 34234 on my VPN, which gets forwarded to my internal port 12312.
If possible, how do I set up transmission to listen to port 12312 while advertising that I can accept connections on port 34234 for the peers?
Edit: or is it possible to have two ports listed for the peer-port? Obviously only the open external port on the other side of the VPN would work, but it would keep transmission listening on the internal port.
