Firstly, the firewall has no connection with your isp (network administrator), are there any connection bars showing in the bottom left of your Limewire screen?? If so try this test, first turn off your firewall for five minutes, see if you can get a search showing, try a d/load. If not, then please post back here with details about your system and your isp (network provider). DON'T FORGET TO TURN YOUR FIREWALL BACK ON!!!
