[acvaldez]

Description	This article describes how to configure Dynamic DNS FortiGate.
Scope	FortiGate.
Solution	Diagram. In the FortiGate 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 the GUI. If it is necessary to configure multiple DDNS, configure them through the CLI. The 'use-public-ip' option is only available when 'ddns-server' is set to 'FortiGuardDDNS'. Related document: FortiGate Admin Guide on DDNS
