Enabling web content Filtering

Enable web content filtering by selecting the Web filter option in firewall policies that allow HTTP connections through the DFL-500 NPG. Next, configure web content filtering settings to control how the DFL-500 NPG applies web content filtering to the HTTP traffic allowed by policies.

To enable web content filtering:

Go to Firewall > Policy .

Select a policy list that contains policies for which you want to enable web content protection.

Select New to add a new policy or choose a policy to edit and select Edit.

The policy must have Service set to ANY, HTTP, or a service group that includes HTTP. See Adding NAT/Route mode policies or Adding Transparent mode policies.

Select Web filter to enable web content filtering protection for this policy. Select show settings to view the current web content filtering configuration.

Select OK to save the policy.

Repeat this procedure for any HTTP policies for which to enable web content filtering.

Blocking web pages that contain unwanted content

Block web pages that contain unwanted content by selecting Web filter in firewall policies, enabling content blocking, and then creating a list of banned words and phrases. When the DFL-500 NPG blocks a web page, the user who requested the blocked page receives a block message and the DFL-500 NPG writes a message to the event log.

You can add banned words to the list in many languages using Western, Simplified Chinese, Traditional Chinese, Japanese, or Korean character sets.

This section describes:

Configuring content filtering

Go to Web Filter > Content Block .
