applications to access the Internet. You can also customize a list of allowed applications which
permits only certain programs to connect to the Internet.
Slide the

turned on

select a port filtering application in the
Applications

the Internet. For example, if you select VPN in the Applications list but do not select HTTP, you can
connect to a VPN server but you cannot connect to a web page using your Internet browser.
Port Filtering settings include:
•
