OK, I shut down the laptop and removed it from the network. Only the desktop is connected. Changed the port to 49152 in limewire for both the listening port and the manual port forward. Also added port 49152 as the TCP port and the UDP port (did NOT get an error that the port is already used?? ...originally had UDP set to 49154).

For this test I disabled BOTH FIREWALLS. With the new port settings, tried both UPNP listening on port 49152 and manual port forwarding listening on the same port. No combination of new port, UPNP or manual forwarding, firewall(s) on or off, and only 1 pc connected to the router.

Any other suggestions???
Thanks,
Jim
