Firewalls communicating to public IPs on Management Interface

mattlede — Wed, 12 Oct 2022 10:13:49 GMT

We are currently seeing the Management Plane of our Palo Alto Firewalls communicating to the following IP-Addresses:

34.96.84.34
107.178.249.217
35.238.108.32

This communication occurs on different Platforms. We see more activity since PAN-OS 10, currently on PAN-OS 10.2.3

Disabled all telemetry on the firewall
Disabled PAN-OS Edge Service
Not using Wildfire
Disabled App-ID Cloud Engine (ACE)
Not using Advanced URL Filtering

Any idea what could be the issue? We like to disable all outgoing communication completely if possible.

Kind Regards

Matthias

Hello,

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 34.96.84.34.

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?

Kind Regards

Matthias

This is just an idea, but maybe set the service route configuration to a loopback and block the traffic?

Device>Setup>Services>Global>Services Features>Service Route Configuration

I noticed these destinations that PA is communicating with.
