Intermittant connectivity
 

I am experiencing a connectivity issue that I ask for guidence in solving. Limewire will sometimes connect to the gnutella network, and other times it will detect a firewall. I have waited, for hours on occasion, for it to connect with no avail. In actuallity I am running a firewall on my PC (nVidia firewall, Windows firewall disabled) and on my DSL router, however even after I disable the firewall on my PC and my router's firewall is set to DMZPlus mode (details below) I still am not connecting. Any assistence with this matter would be greatly appreciated.

System OS : Windows XP SP2 x64 edition (2GB of RAM, 993,~ available while idling with Limewire running)

DSL Firewall
