Manager Remote Access
If managed devices do not have public IP addresses, then enter the management center's FQDN or public IP address that the device will use to establish the management connection. For example, if the management center's management interface IP address is being NATted by an upstream router, provide the public NAT address here. An FQDN is preferred because it guards against IP address changes.
If you use the serial number (zero-touch provisioning) method to register a device, then this field is used automatically for the initial configuration of the manager IP address/hostname. If you use the manual method, you can refer to the value on this screen when you perform the device's initial configuration to identify the public management center IP address/hostname.
