ok n510310ltbc,
Just want to be sure we are on the same page here on this since you have nearly off of the things that could block the ports to deal with on your system..
Your router should have two rules similar to these below, except with your machines Internal IP ..
WinMX ....6699 to 6699 ... TCP... 192.168.1.xxx .. Enable
WinMX ....6257 to 6257 ... UDP... 192.168.1.xxx .. Enable
Then click apply, or make sure that this is how yours looks.
The firewall is a bit harder to mess up since we have the pictures, and I am sure that is fine if you followed the directions there..and I mean messed up in the most loving of ways.. i do it regularly .. my self :roll:
Did you find the Worm Protection portion of your Norton 2005 and get WinMX added to the Permit All list ok?
If you have all of this set properly and are still not working I would invite you to come to our chat room on WinMX to have us help you there where we can also test you download and uploads..

Copy and paste that into your Filter Bar on the WinMX Chat Channel window. There is usually someone that can help you with this around but we are all volunteers there so be patient with us..
