No entries available in DDNS Options

[netmon]

Hi everyone!,

I'm currently facing a problem with DDNS associated with fortiddns.com. The service isn't updating and returns an update error. Additionally, when I attempt to edit the configuration, no servers appear as available. This started after the DNS incident. I have another FGT 100F with the same configuration and it's not experiencing the issue. Has anyone else run into this problem?

Any insights or suggestions would be appreciated.

best regards!

Hello @netmon ,

I don't have experience with ddns, but I found some troubleshooting documents for ddns. Maybe these documents can solve your problem.

Hi Netmon, 

First off i would suggest to not use FortiGuard servers for your DNS Resolution and enabling DNS instead of TLS on the section under your DSN Servers. 

For your DDNS issue, try to set this from the CLI and not the GUI.

I have seen the GUI acting very strange when setting your DDNS there. 

Here's the CLI commands you need to run on your FGT. 

config system ddns

edit 1

        set ddns-server FortiGuardDDNS

        set ddns-domain "YourFGTName.fortiddns.com"

        set use-public-ip enable

        set monitor-interface "wan1"

    next

end

Ultimately, the solution was to enable the set use-public-ip parameter. However, I have another firewall where this step was not necessary. I still find it noteworthy that the server cannot be selected via the GUI, although configuring it through the CLI was sufficient to resolve the issue. Thank you for your responses—kind regards.

FortiGate's GUI is behaving very strangely on some features. 

I've seen some weird stuff going on using their GUI.
