Thanks all for your concern.. the problem is solved.. i restore the working date database from the database revision control. and make some changes to the DNS of the gateway. And now its working fine. i found that the management was downloading the update of the url and application filter but was unable to push to the gateway and made a policy for the gateway.

Thanks.

What happens if you copy + paste that access rule into the policy as a new rule, delete the original, and push policy? That should create the rule with a new Rule ID. Maybe something just got corrupt with that rule in the database?

If you look at the log message, it will tell you exactly why the traffic was allowed: There was an "Internal System Error."

There is a fail open/close switch for that situation.

In this case, that setting is allow.

When you go find the rule that allowed the traffic, it doesn't exist.

Of course, you can set it to fail close if you prefer.

Here's where to make that change:

This begs the question: why the internal system error?

That will likely require a TAC case to troubleshoot.

Hi Kurl,

Could you provide some more information about the problem at hand by answering the following questions:

1) Is it http, https-based sites or both that you are having issues with?

2) Have you enabled the Application Control and URLF blades on the gateway?

3) How have you configured the policy to block those sites?

4) What do you see in the logs?

Many thanks.

hi silver ,

I see that the traffic is accepted .i can ping internet i just cant browse .

Below is the troubleshoot summary:

-- Checked for the drops on firewall but not getting any logs for the test machine.


-- Firewall is accepting the traffic and it is reaching to isp router as well but the communication is not happening.

-- Ping is happening properly but unable to access the same is browsers.

-- Disabled threat prevention blades, application and url filtering blade but the same issue.

-- Then enabled blades again, still the same issue.

-- You have checked with isp router by directly connecting the desktop, then you are not facing any kind issues while accessing. 

-- Created one more profile, installed the policy but no luck.

Hi Kul,

If you can ping the Internet but can't browse then you probably don't have DNS as an allowed service on the relevant policy.

Can you check if that is the case?
