Configuring the Windows XP Firewall

This explains how to configure the Windows XP Firewall to allow WinMX to operate correctly.

1.  Click Start > My Network Places.
2.  Under Network Tasks, click View Network Connections. (Alternatively, right-click My Network Places and click Properties).
3.  Right-click the connection you use for the Internet and click Properties.
4.  Click the Advanced tab, and then click Settings

Note: If the Settings button is unavailable, then the Internet Connection Firewall is not enabled on this connection and you do not need to open any ports (they are all already open).

5.  Click Add to add a new service.

6.  Type a name for the service in the Description of service box, for example, WinMX TCP 6699.

7.  Enter, or the Name or IP address of the computer operating WinMX if different than the XP firewall machine.

Note: You can specify an IP address of a local area network computer, however, in most cases you use (localhost).

8.   Enter the WinMX TCP port number in the External port and Internal port boxes.
9.   Click TCP, and then click OK.
10.  Repeat this process for each port to be opened (WinMX needs both TCP 6699 and UDP 6257 (default ports) mapping here).

At this point you should see your newly create forwarding rules as the picture shows below...

That it. the Windows XP Firewall is now configured.

Note:  The ports shown in the above examples (TCP 6699 and UDP 6257) are are the default ports that WinMX uses.  If youve chosen to use ports different than these in WinMX, then youll need to alter the XP Firewall port numbers to coincide with the changes.
