My setup is as follows. I have a docker setup where i run my vpn server in one container and my transmission application in another container. My transmission container uses the vpn container as a gateway which works quite nice. My only problem is that i'm unable to forward my peer listening port from my airvpn connection to the transmission container. I have added the port forwarding at airvpn.org but dont know how to forward it to my transmission container.
I guess I have to add some iptables rules to my vpn gateway, which uses openvpn+iptables to connect airvpn servers.
Does anyone have an idea of how to configure iptables to handle port forwarding?
