When Web Filter Server Is

Select Block to block access to any requested web page if the external

 

Unavailable

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 Service

Specify a number of seconds (1 to 60) for the ZyWALL to wait for a

 

Unavailable Timeout

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.

 

 

This setting applies to all of your content filter profiles.
