DESCRIPTION
Select Pass to allow users to access any requested web page if the external
content filtering database is unavailable.
Select Block to block access to any requested web page if the external content
filtering database is unavailable.
Select Warn to display a warning message before allowing users to access any
requested web page if the external content filtering database is unavailable.
The following are possible causes for the external content filtering server not being
available:
• There is no response from the external content filtering server within the time
period specified in the Content Filter Server Unavailable Timeout field.
• The Zyxel Device is not able to resolve the domain name of the external
content filtering database.
• There is an error response from the external content filtering database. This can
be caused by an expired content filtering registration (External content
filtering's license key is invalid").
Select Log to record attempts to access web pages that occur when the external
content filtering database is unavailable.
Select this check box to restrict access to all site categories listed below.
Select this check box to clear the selected categories below.
These are categories of web pages based on their content. Select categories in
this section to control access to specific types of Internet content.
You must have the Category Service content filtering license to filter these
categories. See the next table for category details.
You can check which category a web page belongs to. Enter a web site URL in
the text box.
When the content filter is active, you should see the web page's category. The
query fails if the content filter is not active.
Content Filtering can query a category by full URL string (for example, http://
www.google.com/picture/index.htm), but HTTPS Domain Filter can only query a
category by domain name ('www.google.com'), so the category may be
different in the query result. URL to test displays both results in the test.
Click this link to see the category recorded in the Zyxel Device's content filtering
database for the web page you specified (if the database has an entry for it).
Click this button to see the category recorded in the external content filter server's
database for the web page you specified.
Click OK to save your changes back to the Zyxel Device.
Click Cancel to exit this screen without saving your changes.
