Remote access VPN - L2tp over Ipsec

Dear All,

I am new with FortiGate firewall and in my organization I have to deploy remote access vpn with using L2tp over IPsec. anyone of you have ever implemented this type of vpn.

let me know  any kind of notes  that will be more helpful for me .

Also, I have gone through fortigate offical websites - Fortigate KB but things could not get more clear.

Thank you in advance.
