Port Forwarding

How do we do it? I read the man page on natd and it was clear for the most part. But it seems natd enables you to port forward for other machines. If I'm at the U. of Rhode Island and the cap ports for P2P below 1k/s (they're wise to all of them except Carracho ) how do I/can I use port forwarding to get around this?

    No you can't. Port forwarding / masquerading / NAT (network address translation) is a simple yet effective way of routing a local network through a single IP address to the internet (or another larger network).



    What you want is tunneling, and that's a bit more complex, and most likely illegal in your specific case.

    So how do I do it? I presume I need the router password? I have a buddy that works in networking. I pay $ for this connection and P2P is capped.

    I'm not going to pretend I know much about this stuff, but what I think you'll need to do is tunnel the port that's blocked over another port (HTTP, SSH) to an outside computer, which will then redirect the data to the machine you're trying to reach, over the correct port. This is called tunneling as you are tunneling the data over another port to get it by the firewall. So you need to have access to a computer on the outside that you know will be on when ever you need it.
