Microsoft shows a networking sample how to which implements a chat tool.

The thing works. I can chat with the computer in the next cubicle. At
home I can chat with the computer on the other side of the room. But I
can't chat between work and home. Ie, it works within the network but
not over the internet. What is the trick?

thx

Firewalls?

Of course. So what's the trick? I've been on Yahoo chat behind these
walls. I've been on Java aplet chats on-line behind at least the wall
at home. I can't imagine Microsoft has no solution.

You are comparing apples (peer-to-peer) with oranges (client/server).
