Sir have you got the solution? – Velvety

Does macosvpn not provide the example you need? It is written in Objective-C and does specifically handle the L2TP protocol. – Northnortheast

Answer 1

No, you need use SCNetwork and Helper Tool (to get root access) With this link you will be able to create L2TP Protocol and connect with it.

This works even on the latest version MacOS 11 "Big Sure"

The helper tool is needed to get root access so you can make changes to the system keychain. You will put the password and shared secret there, because the configuration will not be able to perceive them from other places. Having created a vpn configuration with the help of SCNetwork, the mac will not be able to automatically connect.

To connect to the created profile, you need to programmatically execute the terminal command

networksetup -connectpppoeservice "name VPN profile"
