Hi.. I recently upgraded to LimeWire Pro and just last week also installed Norton's Internet Security 2004. I'm using XP Pro, 80GB HD, Cable Connection thru local service, Pent III 500. Prior to the the Norton, and the firewall it enables, I had no problems connecting and finding what I wanted. The firewall, however, blocks Limewire and I get a message saying I'm not connected. Clicking on "CONNECT," doesn't work. To get through I must disable the firewall. I printed the Limewire instructions for Firewalls but I find one serious difference. Line 13 reads to set the external and internal ports to 6346. When I went into my program to see thru where I was connecting the port number is 6348. What's the answer to this problem. Thanks... Dov
