Enable Keyword Blocking - select this setting to enable keyword blocking for the
URLs that are listed in the Keyword Blocking section on the Custom List tab.
Step 2 Click OK.
Disable all Web traffic except for Allowed Domains
Selecting the Disable Web traffic except for Allowed Domains check box causes the
SonicWALL security appliance to allow Web access only to sites on the Allowed Domains list.
With careful screening, this can be nearly 100% effective at blocking pornography and other
objectionable material.
The Disable Web traffic except for Allowed Domains check box is not available when the
SonicWALL appliance has a valid SonicWALL CFS subscription. In this case, you can configure
a CFS Policy to block undesirable Web sites.
