SUMMARY
This article describes the ports that you must use to play Microsoft Links 2003 as a multiplayer game through a firewall, a proxy server, a router, Network Address Translation (NAT), or Internet Connection Sharing.



Microsoft Windows firewall
With Microsoft Windows XP Service Pack 2 (SP2), you do not have to manually create port exceptions in the firewall. You may now create exceptions for the program itself.

To do this, follow these steps.

Note Never open a port for a program that you do not recognize.  Click Start, and then click Control Panel. Click Security Center. Click Windows Firewall. Click the Exceptions tab. Click Add Program. Click Browse. Locate the game's executable file, and then click Open. By default, the game is installed in the following location:

C:\Program Files\Microsoft Games\Links 2003\LinksMMIII.exe

</li> Click OK two times.</li></ol>

For additional information about how to use the Windows firewall, click the following article number to view the article in the Microsoft Knowledge Base:

If you are not using the Windows firewall, you may still have to know the ports that are used by the game when you configure your network.

Port listing
To make sure that these ports are open or to open these ports, contact your network administrator or Internet service provider (ISP).

If you are the administrator of the network, view the documentation that is included with your networking software to determine how to open these ports.

To use Links Match Maker and start multiplayer games, the following UDP and TCP ports must be open:
 * Connection to Links Match Maker: 2300
 * News and AutoUpdate: 80

When a multiplayer game is in session, Links 2003 uses the following DirectPlay ports:
