Configuring Content Filtering to Control Internet Access

 

 

 

 

 

STEP 2 Enter the following information:

Enable Content Filter URL: Click On to enable the website access rule, or click Off to create only the website access rule.

URL: Enter the domain name or URL keyword of a website that you want to permit or block.

Match Type: Specify how to match this rule:

-Web Site: If you choose this option, permit or block the HTTP access of a website that fully matches the domain that you entered in the URL field.

For example, if you enter yahoo.com in the URL field, then it can match the website http://yahoo.com/*, but cannot match the website http://*.yahoo.com.uk/*.

-URL Keyword: If you choose this option, permit or block the HTTP access of a website that contains the keyword that you entered in the URL field.

For example, if you enter yahoo in the URL field, then it can match the websites such as www.yahoo.com, tw.yahoo.com, www.yahoo.com.uk, and www.yahoo.co.jp.

Action: Choose Permit to permit access, or choose Block to block access.

STEP 3 Click OK to save your settings.

Mapping Content Filtering Policy Profiles to Zones

Use the Policy to Zone Mapping page to apply the content filtering policy profile to each zone. The content filtering policy profile assigned to each zone determines whether to block or forward the HTTP requests from the hosts in the zone. The blocked requests will be logged.

STEP 1 Click Firewall > Content Filtering > Policy to Zone Mapping.

The Policy to Zone Mapping window opens.

STEP 2 Click On to enable the Content Filtering feature, or click Off to disable it.

STEP 3 Specify the policy profile for each zone. By default, the Default_Profile that permits all websites is selected for all predefined and new zones.
