DDNS

If your external IP address changes regularly and you have a static domain name, you can configure the external interface to use a dynamic DNS (DDNS) service. This ensures that external users and customers can always connect to your company firewall. If you have a FortiGuard subscription, you can use FortiGuard as the DDNS server.

Caution
  • FortiGate does not support DDNS for pure TP mode.
  • FortiGate models 1000D and higher do not support DDNS in the GUI.

You can configure FortiGuard as the DDNS server using the GUI or CLI.
