Firewall blocking Chat Programmes
I need to chat to somebody at their place of work. I normally use MSN but the person at the other end is being blocked by a firewall. Is there anyway to get around this. As far as I know certain sites are blocked by the firewall, like MSN yahoo etc.

There are ways, but it's probably a pretty bad idea to try - circumventing a firewall is almost certainly something you're not supposed to do (it's there for a reason, after all) and will be frowned upon if caught. Better to ask them to unblock it (possibly with a good reason why... 
).

you need to get the appropriate ports opened in the firewall to get chat programs working, unfortunatly finding the correct ports is trial and error. I believe video and voice use the udp protocol rather than the tcp protocol and I believe that many sys admins dont alow udp connections.
