Musicman,
The test that gives you that message is in the setup wizard portion of WinMX and is more then likely not going to show up as able to make that TCP, because WinMX is hard programed atm to check that by going to the old peer caches.
That said this doesnt mean we cant get you configured right. First of all when you do start Winmx as a primary what does it say at the top of the screen?
P= and S= ?
Also what ports did you set in WinMx and the Modem?
Did you set two ports in the modem? seperately one for TCP and one for UDP, specific ports no ranges?
Zone Alarm has been known to cause some folks problems, and many folks not, but until it was uninstalled and the uploads started working did we know for sure
I am wondering do you get search results? Do you get S= numbers ?
Do your uploads work?
ALso what is your Connection type and the company your with?
