msn messenger and chatting behind a firewall?

can anyone tell me how to bypass this annoying firewall and have fun chatting with my friends .

I live in a university campus ... with a very good internet connectivity ... I have been trying to get it out and bypass this firewall but never made it .

plz, i need a big big expert coZ they are very smart .... I mean the people working in firewall,

however, I know that there are some students bypassing this firewall using "your freedom program ". I tried it and never work . and when i asked them they didn't tell me

so .... where are you expert ? !!!!!!!!!!!!!
