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.
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.
