When Content Filter 

Server Is Unavailable

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.

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

requested web page based on the setting in the Block When Content Filter 

Server Is Unavailable field.
