Port Filtering
Like IP Filtering and MAC Filtering, Port Filtering allows you to block access to the Internet. However, with IP
Filtering or MAC Filtering you are blocking access for a particular device, with Port Filtering you are blocking
access for ALL network devices. Port filtering restricts access based on a specified port.
Setting Up Port Filtering
To setup Port Filtering:
From the home page, click on the Advanced Setup tab. Click on the Filtering sub-menu. Scroll down to the
Port Filtering section:
To restrict access to the Internet based on a Port:
•
Enter the Start Port
•
Enter the End Port. If you restricting access from a single port, The End Port will be the same as
the Start Port.
•
Select the appropriate Protocol – TCP, UDP or Both
•
Click on the Enabled checkbox to activate the Port Filtering rule.
•
Click the Apply button.
For example, if you would like to block all network devices on your LAN from accessing HTTP sites (i.e. web
sites that use the HTTP protocol) enter 80 for the Start Port, 80 for the End Port, and TCP for the Protocol.
Check the Enabled checkbox and click on the Apply button.
To remove or disable a Port Filtering rule, simply uncheck the Enable checkbox associated with the rule you
want to disable. Click the Apply button.
Web Content Filter
The Web Content filter allows you to control data flow from the Internet to your LAN. Using various settings,
