After searching the web. You may need to configure your modem for port 6346. Here is a link to the user guide: http://www.voyager.bt.com/2000/downloads.htm

Just follow the instructions they give and you should be okay.

Yoy will also need to make sure that your McAfee Personal Firewall is also configured to allow LimeWire full access. http://www.limewire.com/english/content/firewalls.shtml
