    @Alberto I can't recall of any problem that the Priority got messed up after a crash or regular reboot, sorry.

    ACL are prossesed in TOP DOWN order by priority ?

    When a condition in the ACL is met, all processing is stopped ?

  • BWCBWC Cybersecurity Overlord ✭✭✭

    @Alberto correct, Priority is the main driver and First-Match is final, no other rules are processed.

    this is the response of the support. the machine rebooted due to a software process that locked a core. the HA machine started but the acl was not in correct order




    Hello Alberto ,

    Please be aware that this case will be handled via email only, any assistance that is needed from a live engineer would need you to contact our support line at 800 909 106 or +39 023 045 6009 and enter the case number at the prompt.

    From the case description I see we have issues with high DP core and firewall lockup.

    Web tickets are for basic troubleshooting and questions - P3 tickets. High CPU utilization, Reboot/lock ups are more complex issues requiring a phone call.

    This type of issue is best suited for a phone call and cannot be worked over the web as it looks like it will require in depth troubleshooting and data gathering may be needed. Please give us a call on our support number when you are available to work this issue.
