DESCRIPTION
Select Block to prevent users from accessing web pages that the external
database content filtering has not categorized.
When the external database content filtering blocks access to a web
page, it displays the denied access message that you configured in the
CONTENT FILTER General screen along with the category of the
blocked web page.
Select Log to record attempts to access web pages that are not
categorized.
Select Block to block access to any requested web page if the external
content filtering database is unavailable. The following are possible
causes:
There is no response from the external content filtering server within
the time period specified in the Content Filter Server Unavailable
Timeout field.
The ZyWALL is not able to resolve the domain name of the external
content filtering database.
There is an error response from the external content filtering
database. This can be caused by an expired content filtering
registration (External content filtering's license key is invalid").
Select Log to record attempts to access web pages that occur when the
external content filtering database is unavailable.
Specify a number of seconds (1 to 30) for the ZyWALL to wait for a
response from the external content filtering server. If there is still no
response by the time this period expires, the ZyWALL blocks or allows
access to the requested web page based on the setting in the Block
When Content Filter Server Is Unavailable field.
