To block a Web site that is not blocked by the Content Filter List, enter the host name,
such as “www.bad-site.com” into the Forbidden Domains field. 256 entries can be added
to the Forbidden Domains list.
Note: Do not include the prefix “http://” in either the Trusted Domains or Forbidden
Domains the fields. All subdomains are affected. For example, entering “yahoo.com”
applies to “mail.yahoo.com” and “my.yahoo.com”.
Click Update. Once the SonicWALL has been updated, a message confirming the update
is displayed at the bottom of the browser window.
Note: Customized domains do not have to be re-entered when the Content Filter List is
updated each week and do not require a filter list subscription.
To remove a trusted or forbidden domain, select it from the appropriate list, and click the
Delete Domain button. Once the domain has been deleted, a message is displayed at the
bottom of the Web browser window.
• Enable Content Filter List Customization
To deactivate Content Filter List customization, clear the Enable Content Filter
List Customization check box, and click Update. This option allows you to enable
and disable customization without removing and re-entering custom domains.
• Disable Web traffic except for Trusted Domains
When the Disable Web traffic except for Trusted Domains check box is selected,
the SonicWALL only allows Web access to sites on the Trusted Domains list.
• Don’t block Java/ActiveX/Cookies to Trusted Domains
When this box is selected, SonicWALL permits Java, ActiveX and Cookies from sites on
the Trusted Domains list to the LAN. This check box allows Java, ActiveX or Cookies
from sites that are known and trusted.
• Message to display when a site is blocked
When a user attempts to access a site that is blocked by the SonicWALL Content
Filter List, a message is displayed on their screen. The default message is “Web Site
Blocked by SonicWALL Filter”. Any message, including embedded HTML, up to 255
characters long, can be defined.
The following example displays a message explaining why the Web site was blocked, with
links to the Acceptable Use Policy and the Network Administrator’s e-mail address:
Access to this site was denied because it violates this company’s <A HREF=http://
www.your-domain.com/acceptable_use _policy.htm>Acceptable Use Policy</A>. Please
contact the <A HREF=”[e-mail]”> Network Administrator</A> if you feel
this was in error.
