Troubleshooter,

All you should need to do is map TCP port 6699 INCOMING to your IP address and UDP port 6257 BOTH DIRECTIONS to your IP address.

From a WinMX FAQ:
=============
5.1. How Do I Use WinMX with My Firewall?
It depends on what firewall you are using. With something like ZoneAlarm you just allow WinMX to access the internet, and act as a server, and it will work fine. Otherwise, you have two options:

Option 1

You can map an incoming TCP/IP port to the machine running WinMX.

If you are using a home router or software router (such as ZoneAlarm) this is a very simple procedure, which will be outlined in the documentation that came with your firewall or router. If you are behind a corporate firewall or proxy, you will need to ask your network administrator to do this for you. Some network administrators may not want to do this, in which case you should use Option 2 below. In either case, you will need to know the port number to map. This can be found by going into the WinMX connection settings, and clicking the "Network / Proxy Settings" button. The port number you need to map will appear below where it says "Incoming Connections".

Option 2

You can put WinMX into "Firewall Mode".

This mode doesn't need to have any incoming connections, but will reduce search results because you will be unable to download from other users that are in the same mode (as neither side will be able to accept a connection). Uploads will be pushed outward when in firewalled mode instead of waiting for an incoming connection. To put WinMX into firewall mode, go into the "Connection Settings" click the "Network / Proxy Settings" button, and below where it says "Incoming Connections", select "Unable to accept incoming connections".

===================

Hope that helps.
