22.1.2.3 Customize Web Site Access

You can specify URLs to which the ZyWALL blocks access. You can alternatively block
access to all URLs except ones that you specify. You can also have the ZyWALL block access
to URLs that contain particular keywords.

22.1.3 Content Filtering Configuration Guidelines

You must configure an address object, a schedule object and a filtering profile before you can
set up a content filtering policy. When the ZyWALL receives an HTTP request, the content
filter searches for a policy that matches the source address and time (schedule). The content
filter checks the policies in order (based on the policy numbers). When a matching policy is
found, the content filter allows or blocks the request depending on the settings of the filtering
profile specified by the policy. Some requests may not match any policy. The ZyWALL
allows the request if the default policy is not set to block. The ZyWALL blocks the request if
the default policy is set to block.

22.2 Content Filter General Screen

Click Configuration > Policy > Content Filter > General to open the Content Filter
General screen. Use this screen to enable content filtering, view and order your list of content
filtering policies, create a denial of access message or specify a redirect URL and check your
external web filtering service registration status.
