| You don't need to "unmask" your IP address to play BF 1942 or CS.  Trust me, I play all the time, no problems.  It sounds almost like the TCP/IP ports are blocked on your router, so you can't make the connection from your machine to the server.  Do you have access to the router configuration?  Can you check & see if there are any blocked ports?
