Occasionally, I become unreachable via search, and I can't form connections with anyone at all - this is a mystery. Maybe your router isn't accepting UPnP requests to open the port and just needs to be rebooted or its configuration adjusted.When the I can receive direct connections box is unchecked, I get about half the uploads as I do in QT, which I assume is expected behaviour. Maybe your router has the port open, but your ISP is blocking the incoming traffic before it ever gets to you (some UK ISPs do this). Either way, the port appears "closed" to the outside world. If the port isn't also open on your computer, then the traffic is rejected at your computer. If the port isn't open at the router, then the traffic is rejected at the router.

It's like your computer is bypassing the router and sits directly on the Internet, but just for traffic on that one port. In other words, it asks your router to accept and forward any incoming traffic marked as being for that port to the same port (usually) on your computer. What I can say is that Soulseek is like most any other networking client: When it starts up, it asks the OS to let "listen" on a couple of TCP ports, and it also asks your router (via UPnP) to open and forward corresponding ports. We don't know what you know about how computer networks work, and this isn't the place to explain it all to you. Think and investigate and try different things. There's no magic "just make it work" button.
