if you want to bypass the firewall, while not going to a proxy then do this
I cant guarantee that this will work, my school dodnt figure it out till someone ratted us out so if might work!
go to tools: --- internet options --- connections tab---- click on LAN settings ---- and deselect BOTH boxes under proxy settings.... click apply and then ok and
it should be bypassed----
unless your school has already wisened up and corrected this prob...
