iChat/Adium trouble with proxy

[MalcolmJID]

I'm at college on a wireless network, and there is a proxy in place to access the internet, but unfortunately, iChat and Adium no longer want to connect, even with the proxy details in place within each program.

Can anyone help me out?
Cheers, Karl.

It could be that your college is blocking the necessary ports to allow these chat programs to connect.
