Sorry, I didn't notice you were on a dial up connection. You probably don't have a router. Check your Norton firewall again and make sure limewire is allowed access to the internet. Also make sure the xp firewall is shut off.
See User Cant Connect - LimeWire

Open LW and go to Tools>Options>Speed, and tick the box beside "Disable Ultrapeer Capabilities", and click apply. Sometimes that will cause problems for people on a dial-up connection. You may need to restart LW for the changes to take affect.

This post has tips for setting up LW with a dial-up connection: http://www.gnutellaforums.com/connec...tml#post175733
