Content-filter Service Is Unavailable

itxnc

We're seeing a lot of alerts on our client's USGs and ATPs where the content filter service becomes unreachable for a period of time. Then it comes back. Have been seeing this on and off for a few weeks. Anyone else seeing this behavior?

Hi @itxnc,

We need more information to check the root cause of this issue.

I will contact you in private message for further information.

Hello, after upgrade zld from 4.33 to 4.35 I've noticed that my Security Policy wasn't working because the rule #2 collided with rule #1 while both rules were working on zld 4.33.
Rule #1: lan1 to wan any any ... allow Schedule-Application patrol (for You tube)
Rule #2: lan1 to wan any any ... allow Content filtering
On zld 4.35 only rule#1 was working.
Now on zld 4.35 I had to combine both rules together to have them working both...is that some bug of zld4.35 ?

Hi @LiborK,
It works on both firmware 4.33 and 4.35.

If you'd like to block a specific category of website always and block YouTube (App Patrol) for just a period of time, create the rules as follows.

Rule #1: From lan1 to wan any any -> apply YouTube profile with schedule (14:15-14:45) & apply CF profile

Rule #2: From lan1 to wan any any -> apply CF profile

If the time you access YouTube hits the schedule (ex: 14:20), the traffic hits Rule#1 and never goes to Rule#2, so both YouTube and CF are blocked.

If the time you access YouTube doesn't hit the schedule (ex: 14:50), the traffic hits Rule#2. YouTube is allowed but CF is blocked.

Feel free to let me know if you has questions about applying App Patrol and CF profiles. If you still has questions, please share the configuration file with me via private message.

Hi,

I would like to know how you solve the problem of Content Filter becoming unavailable. We have this problem on one of our router since a few days.

Our user are blocked and in the CF log we can see that the service is unavailable.

Thanks,

Yes we still have the issue intermittently - seems to last for a couple minutes then the service comes back

As my setting on this part, since the database could not include and category all websites.
configure Warn as these two parts, and check again
