How to connect to a VPN with the terminal at boot/login and have the terminal stay open?:

I want to be able to connect to a VPN service automatically when I login to my user. I guess it should be able to do sudo and input the VPN username and password as well. The terminal window should stay open as well so I can press ctrl + c to close the connection to the VPN if I want to.

I’m using Linux Mint Cinnamon 18.3
