From GUI, go to Network -> DNS -> enable FortiGuard DDNS, select the interface with the dynamic connection, select the server that is linked to the account, and enter 'Unique Location'.

From CLI:

 

config system ddns

    edit 101

        set ddns-server FortiGuardDDNS

        set ddns-domain "fgtbacoor.fortiddns.com"

        set use-public-ip enable

        set monitor-interface "wan1"

    next

end

 

Try to NSLOOKUP the fgtbacoor.fortiddns.com and it will be resolved to whatever public IP the FortiGate getting translated into.

Note:

DDNS can only be configured via CLI for FortiGate VMs. Configuring DDNS via GUI is not supported for FortiGate-1000 series or higher or FortiGate-VM.

Configuring DDNS via GUI is not supported when the configured DNS server is not using FortiGuard Servers. FortiGate does not support DDNS when in transparent mode.

By default, one DDNS can be configured through GUI, if it is necessary to configure multiple DDNS, configure them through CLI.
