I doubt its a firewall issue because I've tried configuring mine up the wall, and ive removed all my firewalls and tried... But I am using ZoneAlarm, but I really think it is just a matter of my ISP, becuase my friend with the same Wireless Broadband Connection had the same problem exactly when I did, and weve been using Limewire for a very long time and we have two completely differently configured computers. I'm just gonna call my ISP and ask them if they are blocking any ports.
THanks tho.
