Ok, I was wrong again lol I figured it out though so WinMX is working fine now. I was able to set up a rule for a range of LAN IP's on the network for all outbound traffic, but I had to set up a separate rule for every machine on the network for all inbound traffic. I don't understand why, but that worked so all is good. I'm learning this on the fly so I believe all will be well soon. Downloads, and uploads are working as expected now.
