Lets say I have #VPS, to which I connect from my home server to use VPS IPs, I want to tunnel a couple of external ports of the publicly reachable VPS to the home server, such as port 25, 139, 578 and whatever, each of the mentioned external reachable port of the VPS should be tunneled to the same port on the home server.

What do I need to do to get #ssh to do this from the home server under #Linux to tunnel the external ports of the VPS to the server at home behind a router, maybe a NAT or so?

Give me one example, just to have an idea.
