We are currently seeing the Management Plane of our Palo Alto Firewalls communicating to the following IP-Addresses:
This communication occurs on different Platforms. We see more activity since PAN-OS 10, currently on PAN-OS 10.2.3
Any idea what could be the issue? We like to disable all outgoing communication completely if possible.
These are most likley the update sites the Palo Alto management interface needs to get to for updates, etc., as well as licensing info. The URL updates.paloaltonetworks.com resolves to 126.96.36.199.
What I do is create a custom URL category and apply it to the policy that the management interface uses to go external.
Many Thanks for the information. We manage our Palo Alto Firewalls with Panorama in a disconnected environment. Therefore we cannot allow the Palo Alto Firewalls to communicate to the outside world, not even with a proxy. Updates are all provided by panorama.
Is there an option to disable this communication completely? Or do we just have to live with it and ignore it?
