Hi Mickish,

Have you updated both the "listening port" and "advertised port"? Testing LimeWire on an internal network is notoriously difficult. LimeWire can be listening on one port, yet advertise that it is listening on another. These options are set under the 'Advanced -> Port' and 'Advanced -> Firewall' settings.

For internal networks, we generally rely on multicast to send/receive messages.

Thanks,
Sam
