Справочник Пользователя для SonicWALL 5.8.1

SonicWALL recommends that you make the Default CFS Premium policy the most 
restrictive policy. Custom CFS policies are subject to content filter inheritance. This means 
that all custom CFS policies inherit the filters from the Default CFS policy. To ensure proper 
content filtering, the Default CFS policy should be configured to be the most restrictive 
policy, then each custom policy should be configured to grant privileges that are otherwise 
restricted by the Default policy.

To display the SonicWALL Filter Properties window, select SonicWALL CFS from the 
Content Filter Type drop-down list on the Security Services > Content Filter page, and then 
click Configure. The SonicWALL Filter Properties window is displayed. For configuration 
information about the filter properties settings, see the following sections:

The CFS tab allows you to enable IP-based HTTPS Content Filtering, block or allow traffic to 
sites when the server is unavailable, and set preferences for your URL cache.

The Settings section allows you to enable HTTPS content filtering, select what you want the 
firewall to do if the server is unavailable, and what it should do when access is attempted to a 
forbidden Web site.
