- On the FortiAuthenticator, go to System > Dashboard > Status.
In the System Information widget, select Change beside Device FQDN.
Enter a domain name (in this example, fac.school.net). This helps identify where the FortiAuthenticator is located in the DNS hierarchy.
- Enter the same name for the Host Name. This allows you to add the unit to the FortiGate’s DNS list so that the local DNS lookup of this FQDN can be resolved.
- On the FortiGate, open the CLI Console and enter the following commands using the FortiAuthenticator’s host name and Internet-facing IP address:
config system dns-database
set hostname fac.school.net
set ip 172.25.176.141
set domain school.net
