use dyndns.org inside fortigate

[ahmadking22]

hello

I have FortiGate40F and already I have DDNS from x.dyndns.org

how I can configure this DDNS from FortiGate (from GUI  only server from fortiddns.com )

for example when I write x.dyndns.org with specific port from browser forwarding to server inside my Network 

Best Regards

Based on your request, I guess you want to create a VIP, which can be accessed using the DDNS pointing to the public IP of the FGT and based on a specific port to an internal server, https://community.fortinet.com/t5/FortiGate/Technical-Tip-Using-Virtual-IPs-to-configure-port-forwar... 

L.E. if the WAN ip is dynamically assigned,

• Use the external IP of 0.0.0.0 when creating a VIP for a FortiGate unit where the external interface IP address is dynamically assigned.

Sorry, I dont really understand what you are trying to do.

fortiddns.com it's a public dns so any computer with a dns server configured can query and resolve it.

L.E.

If you want for the FGT to act as a DNS server for internal computers to resolve dns entries into private IPs instead of public, you can set it up to act as a dns server but you would need to point on the computers its internal IP in order to work, https://docs.fortinet.com/document/fortigate/6.2.16/cookbook/960561/fortigate-dns-server

I know fortiddns.com public dns but i need to use other dns like dyndns.org

but there is no choice to use this dns

i think from command-line i can do it  like

config system ddns
edit 1
set ddns-server dyndns.org
set ddns-domain "x.dyndns.org"
set ddns-username "your_username"
set ddns-password "your_password"
set monitor-interface "wan1"
next
end

Hi @ahmadking22 ,

I guess that you are configuring DDNS with another provider than FortiGuard DDNS.

If so, please check this KB:
