K well let me mention something I forgot about earlier =)
I know that the tunnelling thing didn't work last time Vigz but I think I told some people there was someone here at Uni who plays WoW. He plays it through a tunnel called 'Your-Freedom'. When I try to access the your-freedom website to register with them and download their program I find that the uni denies access to the network which probably means that some forms of tunnelling do work
Also I can actually connect to the WoW servers through the uni firewall anyway. However it gives me a latency of at least 5000 and I can't do anything

So just testing the free service probably wouldn't work because I know I can in theory access the servers anyway.
To be honest it only costs $5 a month which is like £3 so I think I might try it out for a month and see how it goes.
Thanks for the help so far
