network – Issues using System Preferences for VPN


My company has a VPN network which staff are encouraged to connect to using an app called FortiClient. The VPN settings look fairly simple, and I would prefer to try use the inbuilt macOS interface to connect the VPN. I’ve tried a few various ways to no avail, does anyone have any luck?

Here are my FortiClient settings:

I notice that the “SSL-VPN” connection type isn’t available in the System Preferences app. Otherwise I have been trying L2TP. Could this be the difference?

Is what I’m trying possible?
