The Networks area lists the networks (e.g. LAN, data transmission network etc) to which your computer is connected. Also shown here is which rule sets apply (see section entitled Rule sets) are protecting the respective network. If you uncheck the relevant network it will no longer be protected by the firewall. However, you should only disable this protection in specially justified circumstances. If you use the mouse to highlight a network and click on the Edit button, you can view and/or change the firewall settings for this network.
