Bypassing School's Sonicwall Filter...

School's just around the corner, and mine uses the evil that is Sonicwall.  Now I've seen 'bypass my schools firewall plzplzplz' threads before, and the response is typically to use a proxy.  With Sonicwall, however, proxies don't work.  It still directs you to the 'content blocked' page, no matter what proxy you use.  So, /comp/, is there anyone out there that can help me in my quest?  There's one free internet up for grabs.

If it's a hardware firewall, have a nice day. If it's software, then maybe someone could help.
