In a situation where Panorama and its managed firewalls lack internet access, updating PAN-OS requires a manual upload of the downloaded PAN-OS images. The process involves:
D . Upload the image to Panorama > Device Deployment > Software menu, and deploy it to the firewalls:
The engineer first uploads the downloaded PAN-OS images to Panorama. This is done through the "Device Deployment" section, specifically under the "Software" menu. This area of Panorama's interface is designed for managing PAN-OS versions and software updates for the managed devices.
Once the PAN-OS images are uploaded to Panorama, the engineer can then deploy these images to the firewalls directly from Panorama. This process allows for centralized management of software updates, ensuring that all firewalls can be updated to the latest PAN-OS version in a consistent and controlled manner, even without direct internet access.
This method streamlines the update process for environments with strict security requirements, allowing for the efficient deployment of necessary PAN-OS updates to maintain security and functionality.
