SUMMARY
This article describes the ports that you must open to play and host a Flight Simulator 2004: A Century of Flight multiplayer game through a firewall, a proxy server, a router, Network Address Translation (NAT), or Internet Connection Sharing.

 Click Start, type firewall.cpl in the Start Search box, and then press ENTER. In the Windows Firewall dialog box, click Allow a program through Windows Firewall.

If you are prompted for an administrator password or for a confirmation, type the password, or click Continue. On the Exceptions tab, click Add program. In the Add a Program dialog box, click Browse. Locate the game's executable file, and then click Open. By default, this game is installed in the following location:

C:\Program Files\Microsoft Games\Flight Simulator 9\fs9.exe

 Click OK two times.</ol>
