Control Panel provides an applet to manage Windows Firewall settings.
However, that applet just touches the tip of the iceberg. Windows Firewall contains a plethora of settings, all of which you can access through this admin tool.
With this tool, you can apply any tweak on Firewall that you can think of. You can manage current incoming and outgoing network connections.
Windows keeps a set of incoming and outgoing rules for all the network applications; they can be managed through this tool.
