Add
the following URLs to your firewall allow list if your firewall
has limited access to the Internet: downloads.paloaltonetworks.com:443
proditpdownloads.paloaltonetworks.com:443
As
a best practice, set the update server to updates.paloaltonetworks.com.
This allows the Palo Alto Networks firewall to receive content updates
from the server closest to it in the CDN infrastructure. The
Palo Alto Networks ThreatVault database includes information
about vulnerabilities, exploits, viruses, and spyware threats. Firewall
features, including DNS security and the Antivirus profile, use
the following resource to retrieve threat ID information to create
exceptions: data.threatvault.paloaltonetworks.com
