Configuring the Website Access Control List

The whitelist and blacklist defines the websites that you want to permit or block.
Up to 32 websites can be defined for each content filtering policy profile.
To add a website access rule in the list, click Add.
Other Options: To edit an entry, click Edit. To delete an entry, click Delete. To
delete all entries, click Delete All.
After you click Add or Edit, the Add/Edit window opens.
Enter the following information:
• Enable Content Filter URL: Click On to enable the access control rule, or
click Off to create only the access control 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 up with this rule:
- Domain: If you choose this option, permit or block the HTTP access of a
website that fully matches up with the domain you entered in the URL
field.
For example, if you enter yahoo.com in the URL field, then it can match up
with the website such as http://*.yahoo.com/*, but cannot match up with
the website such as http://*.yahoo.com.uk/*.
- Keyword: If you choose this option, permit or block the HTTP access of
a website that contains the keyword you entered in the URL field.
For example, if you enter yahoo in the URL field, then it can match up with
the websites such as www.yahoo.com, tw.yahoo.com,
www.yahoo.com.uk, and www.yahoo.co.jp.
• Action: Choose Permit to permit the access, or choose Block to block the
access.
Click OK to save your settings.
