From previous questions/answers I understand that forwarding one certain port to two different IP addresses is not possible.
I have a laptop that connects through the router to the internet. When it's on Wi-Fi it gets a different internal IP than when it's using the Ethernet cable.
My torrent client (Transmission) requires that a certain port is opened and forwarded to the machine. Problem is, I can only forward the port to either the Ethernet interface, or the Wi-Fi interface. I would like to somehow switch from one network interface to the other without interrupting my torrent client. How can I achieve this?
