So I'm running a singular ethernet cable from my router in the living room to my room. Im running a minecraft server on a linux machine (Linux Mint 19.2) which needs to be connected directly to the main router so the port forwarding will work. I have my main windows computer in the same place. I dont want to run another cable from the router, but I want ethernet connection for my main pc. I've tried using a second switch to connect the two computers, but the server won't work with it. Anyways I was wondering how to "pass through" the ethernet connection form the server to the window computer.
