how to tunnel MSN messenger through port 80?

[Con]

Hi guys.

From work i am sat behind a proxy server, the ISP has blocked almost every port except port 80 and port 21!.... This includes the MSN Messenger port. I was wondering if there was a way i could tunnel MSN Messenger though port 80 so i dont have to pay the ISP to change our port settings?

I know it can be tunneled out but i don't know what application could do it or what ports MSN uses?

Any ideas?

A word to the wise.

'Fraid that this post could be seen as asking advise about how to hack. Tsk! We're a very square outfit when it comes to hacking. Sharp 90 degree corners, four of 'em.

*Edit. Sorry, Con. I was too fast on the watchdog thing this AM.

erm its not "hacking" or "illegal" in anyway, its simply blocked because every port that we werent using is blocked, i have permission to tunnel it out if i can find a way.

MSN uses port 1863/TCP. In order to tunnel it, you require two ends! Obviously you have one end at your end, but you need another end somewhere out on the Internet. Without two ends, you have a tunnel with only one end, which isn't very useful.

So, you need to find either a service that does proxying or tunneling, or someone friendly who will provide such a service on your terms.
