Links 2003: Network ports are required with multiplayer games (330382)

MORE INFORMATION

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.

1. Click Start, and then click Control Panel.
2. Click Security Center.
3. Click Windows Firewall.
4. Click the Exceptions tab.
5. Click Add Program.
6. Click Browse.
7. 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

8. Click OK two times.

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.
