Yes. The issue is BlackICEDef is alerting you to the connections Limewire is establishing with other Gnutella clients. You need to open the Advanced Firewall Settings for BlackICEDef, select the Ports tab, and add a new setting to Accept TCP for the port you are using in Limewire. This would probably be 6346 or 6347 unless you have chosen a different port in the Limewire settings.
