Can we use Lets Encrypt certificates for SSL VPN on multi VDOM fortigate 1200D firewall?

Hi Team, Our client is requesting us to use Lets Encrypt certificate for SSL VPN certificate protection. We are hosting this customer on the 1200D datacentre firewall as a VDOM.

 

Please advise if we can use this feature? 


I am getting the below message and the "Lets Encrypt" button is greyed out.

 

Use Let's Encrypt and the ACME protocol to automate certificate creation and maintenance. You will need to enable DDNS or purchase a domain.

 

Kind Regards,

Yes, you can use Let's Encrypt certificates for SSL VPN on a FortiGate 1200D firewall with multiple VDOMs, but you need to ensure a few prerequisites. The "Let's Encrypt" button being greyed out typically happens if DDNS (Dynamic DNS) is not enabled or if a valid domain name is not configured. To resolve this, ensure your domain points to the public IP of the firewall, enable DDNS if using dynamic IP, and make sure the ACME protocol is supported. Once these conditions are met, the Let's Encrypt certificate creation should work for SSL VPN. For more detailed guidance, check FortiGate documentation or visit firacode.org.
