Getting gnutella to work behind firewall

Hi

I am at a school which has a very strict firewall.

The only ports which are open are ports 21 and 110. I can also access services on port 80 via a proxy running on port 8080. How can I get this to work with Morpheus (My choice of a Gnutella client)?

I can also, but prefer not to, access all ports by using SSH-Tunneling through my home router which is running SSH on port 21. But I think that can confuse Gnutella and it will try to establishe a connection to my router, not to the other end of the tunnel. But that limits the download speed but if that is the only way then I would like to use it.

Is there any way to get this to work? All ideas are welcome.

Regards,
