Advanced Features – Port Filtering
Port Filtering allows you to block outgoing Internet connections and permit only selected
applications to access the Internet. Traffic is identified by port numbers. Some applications are
pre-defined. You can define additional applications if you know the details of the traffic used and
generated by the applications.
NOTE: You can view the current Port Filtering setting (ON/OFF) in the Settings panel on the Web
UI Home page.
Port Filtering
To turn on port filtering, move the ON/OFF slider to ON.
To turn off port filtering, so that any application can connect to the Internet, move the slider to
OFF.
Applications
Select the applications you want to be able to access the Internet and click Save Changes.
