Can't connect to Steam at my college

Set up a proxy server at your house then connect to it from school using your IP and port 80

You can do this using linux

Nice website Don thanks, i bookmarked it.

One time (actually plenty of times) i tried to enter TKC website from a place where i used to work, the site was blocked, i googled every possible way that i could use to enter the blocked website, but none of them worked (http://www.hongkiat.com/blog/9-alternat ... ked-sites/) except for one, use google website translator, i put TKC website in the translator and tried to translate it from any language to english and I finally entered, it worked! lol although it didn't looked the same, the images were not there and some other stuff, maybe it was the pc not sure. But i entered that way lol.

The Problem:
Most school firewalls only open on port: 20, 21, 80, 443, etc.
And they block all of the other ports.
Steam uses ports :
UDP 1200 (For the Friends service)
UDP 27000 to 27015 inclusive
TCP 27020 to 27050 inclusive

So it isnt open. But if there was some way to channel those ports thru a different port using a proxy server at his house then he would be able to connect.
