Correct, still not working. I even went ahead and opened all the ports from the FAQ in my router, even though I don't think my router's firewall was preventing any internal LAN traffic. Still no connection between server and receiver, even though both are satisfactorily connected to the router.

So at this point, all the ports from the FAQ are open in my router's firewall and the Windows XP firewall, and I still can't get a connection.
