When Content Filter
Server Is Unavailable
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.
Content Filter Server
Unavailable Timeout
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.
