Configuring Blocked URLs to Prevent Access to Websites

in the navigation tree.
The Blocked URLs page appears.

• URL: Enter the domain name or keywords for a website that you want to
approve. Separate multiple entries with semicolons (;).
• Match Type: Specify the method for applying this rule:
- Web site: Choose this option to block access to the domain name exactly
as shown. For example, if you enter www.yahoo.com for the URL, then
your users are prevented from accessing www.yahoo.com, but they can
access www.yahoo.com.uk or www.yahoo.co.jp.
- URL Keyword: Choose this option to block access to any website with a
domain name that contains the configured keyword. For example, if you
enter yahoo for the URL, then your users are prevented from accessing
websites such as www.yahoo.com, tw.yahoo.com, www.yahoo.com.uk,
and www.yahoo.co.jp.
