Ok here is the specs:

I am on a LAN Based Network with 4 PCs (3 PCs on Windows ME and 1 On Windows XP) all 4 PCs connect to the internet thur 1 main server (Windows 2003 Server) Which is directly connected to the internet thur a Cable Modem.

I wanna host my own games instead of just joining, but the Windows 2003 Server doesn't take incoming connections.

I know that a dont have a router, or a gateway, but the server does have a firewall (Internet Connection Firewall)

The question is, How do I configue the internet conection firewall on windows 2003 to accept connections from other people when I host games.

In other words, I wanna know how to open ports on ICF for JJ2.

Please help.
