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.

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

    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.
