Represents the IP address or host name of the server from which to download updates from Palo Alto Networks. The current value is
updates.paloaltonetworks.com. Do not change this setting unless instructed by technical support.
Verify Update Server Identity
If you enable this option, the firewall or Panorama will verify that the server from which the software or content package is download has an SSL certificate signed by a trusted authority. This adds an additional level of security for the communication between firewalls or Panorama servers and the update server.
Verify the update server identity to validate that the server has an SSL certificate signed by a trusted authority.
Choose the type of DNS service—
DNS Proxy Object—for all DNS queries that the firewall initiates in support of FQDN address objects, logging, and firewall management. Options include:
Primary DNS Server
Enter the IP address of the primary DNS server for DNS queries from the firewall. For example, to find the update server, to resolve DNS entries in logs, or resolve FDQN-based address objects.
Secondary DNS Server
Optional) Enter the IP address of a secondary DNS server to use if the primary server is unavailable.
FQDN Refresh Time (sec)
Enter the number of seconds after which the firewall refreshes an FQDN. The timer starts when the firewall receives a DNS response from the DNS server or DNS proxy object resolving the FQDN.
The FQDN Refresh Time doesn’t apply to an FQDN used for an IKE VPN peer IP address (on any firewall model). The firewall refreshes an IKE VPN peer IP address configured as an FQDN based on the TTL expiration time configured on the DNS server or DNS proxy object.
Proxy Server section
If the firewall needs to use a proxy server to reach Palo Alto Networks update services, enter the IP address or host name of the proxy server.
Enter the port for the proxy server.
Enter the username for the administrator to enter when accessing the proxy server.
Enter and confirm the password for the administrator to enter when accessing the proxy server.
NTP Server Address
Enter the IP address or hostname of an NTP server that you will use to synchronize the clock on the firewall. Optionally, you can enter the IP address or hostname of a second NTP server to synchronize the clock on the firewall if the primary server becomes unavailable.
When an NTP server keeps all network firewall clocks synchronized, scheduled jobs run as expected and timestamps can help identify the root causes of issues that involve multiple devices. Configure a primary and a secondary NTP server in case the primary NTP server becomes unreachable.
You can enable the firewall to authenticate time updates from an NTP server. For each NTP server, select the type of authentication for the firewall to use:
Enable NTP server authentication so that the NTP server approves the client and provides synchronized updates.
