When using the PAN-DB public cloud, each firewall
accesses the PAN-DB servers in the AWS cloud to download the list
of eligible servers to which it can connect for URL lookups. With
the PAN-DB private cloud, you must configure the firewalls with
a (static) list of your PAN-DB private cloud servers that will be
used for URL lookups. The list can contain up to 20 entries; IPv4
addresses, IPv6 addresses, and FQDNs are supported. Each entry on
the list— IP address or FQDN—must be assigned to the management
port and/or eth1 of the PAN-DB server.
