I dusted off and re-installed Axis and Allies Iron Blitz to play online with friends. I choose multiplayer, tcp/ip, host game....and it gives me my host IP address. When my friends choose Join Game and enter the IP address there is always a failure to connect. If I use another computer in my house (using the same router) I can connect using that IP address. Q1: Why can I only get a connection from a computer connected to my router? Q2: How can I connect to others online?
