PAN-DB URL Filtering
License : valid
Cloud connection : not connected
URL database version - device : 0000.00.00.000
URL protocol version - device : pan/0.0.Environment
- Next-Gen firewalls
- Supported PAN OS
- Management connectivity to PANDB Cloud is via the Data plane
- URL license enabled
Cause
- Management interface connectivity to the internet is currently routed through the dataplane.
- The security policy designed to permit the PAN-DB cloud connection is has the URL category.
- Because the firewall lacks an initial connection to the PAN-DB cloud, it cannot identify the URL category, preventing the security policy from ever matching.
- Consequently, the management interface remains unable to connect to the URL cloud due to the absence of a functional security policy.
Resolution
- Configure an open security policy to allow the management traffic to reach internet.
- The other secure option is to configure security policy to allow the management traffic to above listed PANDB cloud URLs.
