Configuring L2TP VPN on Windows Server
PPTP is obsolete and no one should use it. It was widely used because it was so simple to set up. But we need to stop because it is no longer safe to use.
How To Make The Switch to L2TP

Then make sure you have enough ports available for the potential users.
Then reboot the server or it won’t work. Restarting the services is not enough. Reboot.

Type the same preshared key that you entered on the server.
