    Edit Advanced IP Defense Connectivity Settings

    Configure connectivity settings to ensure reliable communication between your firewall and the Advanced IP Defense cloud service.
    Where Can I Use This?What Do I Need?
    • PAN-OS 12.2 and later
    • Strata Cloud Manager
    • Advanced IP Defense license
    • Admin access to firewall or Strata Cloud Manager
    • Network connectivity to Advanced IP Defense cloud service endpoints
    Advanced IP Defense relies on continuous communication between the firewall and the Advanced IP Defense cloud service to deliver real-time threat detection. The firewall sends two types of messages to the cloud: copies of DNS response IP-TTL pairs that Advanced IP Defense uses to build a per-tenant DNS state table, and Advanced IP Defense lookup requests that query IP attributes and direct-to-IP status for a given destination. Because these exchanges happen inline with traffic processing, connectivity reliability directly affects detection accuracy and user experience.
    On a cache miss, the firewall allows the initial session to pass (fail-open) and asynchronously queries Advanced IP Defense for a verdict. The firewall does not hold or buffer packets while waiting for the cloud response. Once the verdict is returned, the local cache is populated and the policy is strictly enforced on all subsequent sessions matching that IP. If Advanced IP Defense becomes unreachable, the firewall reverts to fail-open to prevent a network outage.
    The firewall caches IP attributes locally to reduce the volume of cloud lookups. The firewall only queries Advanced IP Defense on a cache miss—when it encounters an IP that isn't in the local cache or whose cached attributes have expired.
    The firewall also periodically pulls updated allowlist files from the cloud to pre-populate known-safe entries locally. This pull occurs at regular intervals and delivers two per-tenant files: one for the Advanced IP Defense allowlist and one for the direct-to-IP allowlist. If the firewall can't reach the cloud endpoint, it continues to use the most recent cached version of the allowlists. When the firewall reaches its maximum DNS cache capacity, it fails open on direct-to-IP detection and doesn't take action on direct-to-IP traffic until capacity is available.

    Edit Advanced IP Defense Connectivity Settings in Strata Cloud Manager

    Configure Strata Cloud Manager connectivity settings to enable communication with the Advanced IP Defense cloud service for real-time IP attribute lookups and direct-to-IP detection.
    Strata Cloud Manager manages connectivity settings for cloud-managed firewalls and Prisma Access deployments. Connectivity settings control how your cloud-managed infrastructure communicates with Advanced IP Defense. Proper connectivity configuration ensures optimal performance and reliability of Advanced IP Defense threat detection across your cloud-managed environment.
    1. Log in to Strata Cloud Manager.
    2. Select ConfigurationDevice SettingsCloud Services to edit the Advanced IP Defense connectivity settings.
    3. Verify Advanced IP Defense cloud service connectivity status.
      The cloud-managed infrastructure uses an asynchronous fail-open model for cloud lookups. On a cache miss, traffic is allowed to pass and the system queries Advanced IP Defense asynchronously. Once the verdict is returned, the local cache is populated and the policy is enforced on subsequent sessions. If Advanced IP Defense becomes unreachable, the system fails open to prevent a network outage.
      Ensure that network connectivity to Advanced IP Defense endpoints on port 443 is stable. Verify DNS servers are configured and can resolve Advanced IP Defense domain names.
    4. (Optional) Select ConfigurationDevice SettingsServices to configure your proxy server settings.
      If your cloud-managed infrastructure is deployed behind a proxy server or in an environment that requires proxy authentication, you must configure proxy settings to enable communication with Advanced IP Defense:
      • Enter the proxy server IP address or FQDN
      • Specify the proxy server port number
      • Enter proxy authentication credentials if required
      • Enable the option to use proxy for inline cloud services
      The proxy server password must contain a minimum of six characters.
    5. Verify network connectivity to Advanced IP Defense cloud service endpoints.
      Ensure that your cloud-managed infrastructure has network connectivity to the Advanced IP Defense cloud service endpoints. The infrastructure must be able to reach the Advanced IP Defense cloud service on port 443 (HTTPS) for secure communication.
      You can verify connectivity by:
      • Checking network routing to ensure traffic to Advanced IP Defense cloud service endpoints is not blocked
      • Verifying that security policies allow outbound HTTPS traffic to Advanced IP Defense cloud service IPs
      • Confirming that any proxy servers or firewalls between your infrastructure and the internet allow traffic to Advanced IP Defense.
    6. Select ConfigurationDevice SettingsServices and verify that you've configured DNS servers to enable DNS resolution for Advanced IP Defense cloud service endpoints.
      The cloud-managed infrastructure must be able to resolve the Advanced IP Defense domain names to IP addresses. Ensure that your infrastructure has access to DNS servers that can resolve these domain names. You can specify primary and secondary DNS servers to ensure redundancy.
    7. Select ConfigurationDevice SettingsServices and click Test Connectivity to verify that the cloud-managed infrastructure can successfully communicate with Advanced IP Defense.
      Palo Alto Networks recommends testing the connectivity after editing the connectivity settings to validate your changes. A successful test confirms that your connectivity settings are correct.
    8. Select MonitorSystemCloud Services to monitor Advanced IP Defense connectivity status.
      After enabling Advanced IP Defense, monitor the connectivity status to ensure the cloud-managed infrastructure maintains a stable connection to Advanced IP Defense. Check for any connectivity errors or warnings that may indicate network issues
    9. Push your changes.

    Edit Advanced IP Defense Connectivity Settings in PAN-OS and Panorama

    Configure PAN-OS and Panorama connectivity settings to enable communication with Advanced IP Defense for real-time IP attribute lookups and direct-to-IP detection.
    PAN-OS and Panorama manage connectivity settings for on-premises firewalls and Panorama-managed deployments. Connectivity settings control how your firewall or Panorama communicates with Advanced IP Defense. Proper connectivity configuration ensures optimal performance and reliability of Advanced IP Defense threat detection across your on-premises infrastructure.
    1. Log in to thePAN-OS web interface.
