1st, are u the author of this topic : http://www.managames.com/Forum/ftopic583.php
If yes, you should have answered in the same topic, it's more easy to follow your trouble.
So, I just had a look at PFConfig (1st time I'm hearing about it). Is your router in the supported list :
Unfortunately, I cannot provide you a step by step way to make your config work. But here a few things :
- turn off your firewall (turn it on later, once the game will work, so u'll know u just have to configure ur firewall to make everything work)
- forward the UDP port 4321 on ur router (or let PFConfig handles it, if it's able to do that)
Read the doc here :

And look there http://www.portforward.com/routers.htm
for instructions about how to configure your router, if it's in the list.
Some time the connection test may be wrong, so if you have a friend to help u to test ur connection, it could be better...
