I am trying to sign into MSN Messenger at work. They block the typical chat parts which means I can't connect. I have tried running a local proxy to get past the firewall. If I use the standard ports for iChat it goes through fine with the proxy. Its logs in and chats just fine. When I try to do the same with MSN Messenger on any client (fire,proteus,msn) is just hangs and times out. All the other protocols (AOL,yahoo) sign in and out just fine. Is there something with the mac client I need to do special. Also, the PC clients log in just without any modification. Yes, I have checked my Username/Password and it works fine....
