SUMMARY
This article describes the firewall ports that you must open for an Xbox 360 console to work correctly with a computer that is running Microsoft Windows XP Media Center Edition.



MORE INFORMATION
Media Center Extenders, such as an Xbox 360 console, use network ports to communicate over the network together with computers that are running Microsoft Windows XP Media Center Edition 2005. Sometimes a firewall that is running on the Windows Media Center-based computer will block Media Center Extender programs from using these ports.

If you use a third-party firewall (a firewall that is not a Microsoft firewall), you may have to manually configure the firewall to allow for access to the ports for specific programs. The firewall manufacturer may prompt you to configure the firewall by using one of the following methods:
 * Some firewall manufacturers will want you to configure the firewall for the specific program. In other words, you would configure the firewall to allow for only specific programs to access certain ports.
 * Some firewall manufacturers may want you to modify the specific ports that the program uses.

To configure a firewall, you must know the specific name of the program, the port that the program requires, and the direction of the communication signal.

The following table lists the specific information about Media Center Extender programs that you must know to configure some non-Microsoft firewalls:

The procedure for manually configuring a firewall is different for each firewall model and for each firewall manufacturer. For more information about how to configure your firewall, see your firewall documentation.
