kazaa is pc only. but any software using the gnutella network should be connecting to port 6346. I use Acquisition which is a mac only gnutella browser which listens to port 6346 and worked previously to firing up the firewall. Even though the firewall set to allow 6346 tcp and udp, limewire, acquisition, ftp, irc... fail to connect.

This seems to be a bigger problem than setting which port limewire listens to.
