You are not permitted to configure port numbers between 0-1024 and 63000-65000, or port numbers 4369, 5671, 5672, 5986, 6379, 8000, 9100, 15672, 25672. Additionally, you are not permitted to reuse port numbers you already assigned to the Syslog Collector applet.

      If not, upload them as described in Configure the Broker VM and Save.

    2. Specify the Broker VM FQDN.

      Right-click the Broker VM, select Configure. Under Device Name, enter your Broker VM FQDN. This FQDN record must be configured in your local DNS server.

    5. To enable agents to start using Broker VM caching, you must add the Broker VM as a download source in your Agent Settings profile and select which Broker VMs to use, as described in Add a New Agent Settings Profile.

    To help you easily troubleshoot connectivity issues for a Local Agent Settings applet on the Palo Alto Networks Broker VM, Cortex XDR displays a list of Denied URLs. These URLs are displayed when you left-click the Local Agent Settings applet to view the Connectivity Status. As a result, in a situation where the Local Agent Settings applet is reported as activated with a failed connection, you can easily determine the URLs that need to be allowed in your network environment.

  6. Manage the local agent settings. After the local agent settings have been activated, left-click the Local Agent Settings connection in the APPS column to display the settings, and select:

    • Configure to change your settings.

    • Deactivate to disable the local agent settings altogether.
