firebox http proxy fails

Posted on 2010-01-05
Last Modified: 2013-11-21
hello all,

I have a watchgaurd x750e running 10.2 and occaisionally the traffic on port 80 simply shuts down, https sites for instance on 443 and all other traffic is not interupted. The problem resolves after powercycling the device. As port 80 traffic is a hot and bothered issue I have been unable to keep the device in a failed state to observe the logs to define the problem further. I  webblocker and http proxy but have not found a running thread of symptoms to clarify this issue. Have any of you expirenced this or have suggestions?

    There is one more minor update 10.2.11

    Try that

    Are you using Fireware or WSM?

    The device is running fireware v10.1 1, I am accessing it via WatchGaurd Syatem Manager 10.1.0-B176735. I will get the lkates greatest releases and see if that helps.

    please check autoblock causing the problem?

    Few things you can check:
    1. In traffic monitor if you get entries like:
     getredirname: can't find filter rule
    Then your network is infected with malware [eating up all the memory on HTTP proxy]; clean up the systems and the issue would be resolved.
    As a workaround you can use filtered HTTP Service [also called packet filter HTTP service]; but you would loose control like webblocker, anti-virus, restricting MIME/extensions/headers [all proxy functions].

    2. Look at system manager, blocked sites list; if you see your DNS server or gateway listed there, then go to Policy Manager [Setup->Intrusion Prevention->Default PAcket handling] and uncheck auto-block source of packets not handled [from what you have posted earlier; as you are able to access HTTPS sites this option does not really look valid to me].

    3. Look at traffic monitor; as you have enabled webblocker there is a possibility that connection to server is lost and in Policy Manager you have configured to deny all outbound traffic when connection to server is not available. Go to: Policy Manager, select Tasks > WebBlocker > Configure > Advanced; Server Timeout; Then > Deny access to the website.

    Please check and update.

    Thank you.

    I found the problem to be connection with my webblocker database and upgrade forced me to reinstall the DB and that rectified the issue.

    The suggested update indirectly resolved the issue. The webblocker DB was the root of the issue. Applying the update forced a rebuild of the DB.
