On the Watchdog Status Screen, “URL Blocking” is Red or has a Question Mark. What does this mean?

 

This could mean several things. Watchdog’s URL Blocking status functionality depends upon the following factors:

 

The IP address of the computer on which you have installed Watchdog must be getting filtered, and the profile must be blocking the Pornography category.  Otherwise, the URL Blocking Status will be red (fail).

The R3000 must be configured to serve the default block page for the IP address of the computer on which you have installed Watchdog.  You cannot use your own custom block page because Watchdog will fail to interpret the response, resulting in a question mark ("?") for the URL Blocking status.

Special note about using Watchdog in a load-balanced environment:
--------------------------------------------------------------------

Watchdog does not direct a request to a particular R3000; it sends the request to the Internet, just as a user would do. When the request gets blocked by an R3000, Watchdog records which R3000 it was, and sets this R3000's
blocking status as "good," while all other R3000s in the pool get flagged as a question mark ("?").

If the requests that Watchdog generates never gets load-balanced to a specific R3000, that R3000 will always show a question mark ("?"), but chances are that a request will eventually hit each box.  As long as you don't see
a red "failed" status, the filtering environment is still functional.
