FortiDDNS : Unable to retrieve DDNS server information

[semyotai]

Hi All,

I got error as below when FortiDDNS configured in my Fortigate 60D. Firmware version is 5.2.5

Unable to retrieve DDNS server information from the FortiGuard Service

After performing some troubleshooting commands, error as below appeared.

CTL_KBR #

Is this issue related to public IP has been blacklisted?

I'm having the same issue.. did you solve the problem?

Have you tied the DDNS host name to your WAN interface?

Hi Dave,

thank you for your answer..

Yes, I have 2 WAN interfaces on this fortigate and I've tried with both.. Like you, I'm using FortiGuard DNS Servers.

My guess is that because both of the routers behind the firewall do NAT, my WAN addresses are internal addrees 192.168.x.x . I've configured a DMZ host on the router that points to the firewall internal WAN IP and everything else works just fine.

TBH I was thinking that this would have not been a problem but I can't see any other explanation or difference between this and another Fortigate Unit where I use DDNS without problem. I'm using 6.0.3 on both units.

I did not try to configure it directly from the CLI.. Maybe that's just a GUI issue.
