Connecting Using an SSH Tunnel as Proxy Server

[prodonjs]

I am trying to set up a method to use when I am at college to use LimeWire. Since our network blocks P2P traffic, my plan was to run a small Linux client as a virtual machine hosted at my home network, and then use SSH to create a dynamic port forwarded tunnel back to my laptop at college.

So far, I have gotten things to work from the download side. That is, I can set up the SSH tunnel to dynamically forward on port 6890, and then I configure LimeWire to listen at the localhost port 6890 as a Socks4 proxy. I can then get a full strength connection and everything seems to be fine, except I have not yet had anyone download from me, and when I tried downloading a torrent, I was unable to upload a single bit.

What could be causing the issue? I have port 6890-6900 forwarded on my home network's router to the Linux machine running the SSH server. That should mean then, that those ports can accept incoming requests and then forward them back to my local machine. I am pretty sure there is just one thing I am missing. I have those ports opened in the Linux iptables firewall, and all of the traffic back to that port on my local machine should be handled through the established SSH connection over port 22.

Has anyone got a better understanding of how to set up SSH as a proxy server? I couldn't find a very detailed reference for the exact type of setup I need to use. Thanks in advance for any help.
