So I want to play Halo multiplayer at university. My university (in the UK) has a firewall, and I want to know if there is any way around this. At the moment if I try to open multiplayer in Halo, my system hangs. Multiplayer does not work for UT 2004 either. I have turned off my OSX's firewall. I have no 3rd party anti-virus software/firewall. Please can someone tell me its possible to circumvent my university's firewall. Please can someone tell me how. I need my Halo fix!
