When a new firewall is deployed under Panorama 5.x, the device shows as connected under the Managed Devices tab. However, it appears as "out of sync" under Panorama for Shared Policy and Templates.
Resolution
In order for a managed firewall to be in sync with Panorama, it must be added to a device group and under a template.
The firewall can be added to an existing newly created device group. Commit these changes on Panorama first, then commit under the device group section.
Add the firewall under an existing or newly created template. Commit the changes first on Panorama, then commit changes on the templates section.
After the commits, the added managed firewall should be in sync.
