Fortigate DDNS

[rezafathi]

Hi

I want to enable ddns in fortigate but i can not select any servers in server list. How can i config ddns?

What do you mean by "can not select"? Are those options dimmed? Is your DNS working, like pinging "www.google.com" from the FGT?

Hi @rezafathi 

You configure the DDNS and also from the CLI 

To configure DDNS servers other than FortiGuard in the CLI:

config system ddns
    edit <DDNS_ID>
        set monitor-interface <external_interface>
        set ddns-server <ddns_server_selection>
        set server-type {ipv4 | ipv6}
        set ddns-server-addr <address>
        set addr-type ipv6 {ipv4 | ipv6}
    next
end.

Hello @rezafathi ,

Maybe this can be related to your DNS setting. If you are not using FortiGuard DNS, this may be the reason. Could you check your Fortigate DNS settings?

Hi @rezafathi,

Please note that configuring DDNS in the GUI is not supported if:

• The FortiGate model is a 1000-series or higher.
• The FortiGate is a VM.
• The DNS server is not using FortiGuard as the DNS.
• FortiGate does not support DDNS when in transparent mode.

You can try configuring in the CLI as suggested by esalija.
