How to allow certain Services (Antivirus, Udateservers)

Hello, the UTM has started to block an Kaspersky Antivirus updates or signuature renewals (this started a month ago after some UTM upgrades. The same happens to other update Services for some garphics Adapters (Geforce), O&O Imanging Software etc.

BTW, Kaspersky has lots of update Servers. The download of the new files start but end up in freeze at 65 - 83% (it varies). Switching off the UTM an bringing the PCs directly to the Internet Show that the UTM configuration is stopping the process. Any ideas?

  • I found a similar problem with Sophos XG firewalls where the same symptoms were appearing and Kaspersky updates fails halfway through. A bit of digging around showed that the firewall was blocking virus definition files ending with .dat extension as these are categorized as video files and the firewall policy is to block videos.

    Creating exceptions for web filtering in the following manner :

    ^[A-Za-z0-9.-]*\.kaspersky-labs.com\.?/
    ^[A-Za-z0-9.-]*\.kaspersky.com\.?/
     
    solved the issue for me.

  • Hi, Mihira, and welcome to the UTM Community!

    Not many that join us here start with an answer - good for you!

    You did what I was trying to get the others in this thread to do - you looked at the log.

    Cheers - Bob

    Hi Mihira,

    what exams do you leave in your exception? It still does not work :-(

    First I had

    ^https?://([A-Za-z0-9.-]+\.)?kaspersky\.com/

    maintained. Then I had read your post and changed to

    ^[A-Za-z0-9.-]*\.kaspersky-labs.com\.?/
    ^[A-Za-z0-9.-]*\.kaspersky.com\.?/

     

  • Please note that my exception rules were for Sophos XG firewalls which uses the SFOS v16

  • ^https?://([A-Za-z0-9.-]+\.)?kaspersky\.com/ would be one correct form in the UTM.  You see in the log lines that your Kaspersky accesses did not qualify for your Exception.

    I will try it and feedback...

    But you see in the log lines that my Kaspersky accesses did qualify my Exception - or have I got that wrong?

    Hi Bob,

    I think the problem is an other...
    I have disabled the exception and at the transparency mode exceptions i add the source host of my Kaspersky Update Server. Now it works :-)

    So the problem is the transparent proxy, right?

  • hi this a solution but files .dat are denied they are identified as video files 

    how to do exception ? for more days ago a search about this issue i found that I enable to download files .dat 

    is there any solution ?
