No DDNS Server add?

Hello,

if I understand it correctly, it is not possible to add new DDNS Server in the FortiOS.

The reason is simple, we are an ISP and we have self DDNS server available. Which this one intend to take advantage of so that externally checks also sees it is our firewall.

If there is even a possibility to write your own DDNS server I would be grateful.

best regards

Markus

In CLI: 

config system ddns

set ddns-server genericDDNS

set ddns-server-ip x.x.x.x
