College Connection Problems
 

I've gone through all of the steps towards configuring my firewalls to LW and it still says that I am behind a firewall that won't allow me to connect. Even though I have friends in my dorm that download off of gnutella via bearshare and limewire, i'm pretty sure my isp is screwing with it. I do not use an external router, I plug my network cable directly into the wall. I was just wondering if anyone could tell me the best way to get around this. I hear about people using a proxy as a last resort and if that's the case could someone explain to me the best way to set one up. Thanks
