applications will be blocked from accessing the Internet. Traffic is identified
by port numbers. Some applications are pre-defined. You can define
additional applications by clicking the "Add Custom Application" button, but
you need to know details of the traffic used and generated by the applications
you wish to define. In particular, you need to know the port numbers and the
protocol (TCP, UDP) used by outgoing traffic.

pre-defined or custom applications are allowed to access the Internet.
