Ok when you need to configure vpn on more PC is easier to do this with powershell than with mouse clicking ... Here it is example for L2TP oveer IPSec.
Add-VpnConnection -Name "<vpn-name>" -ServerAddress "<address-to-your-server>" -TunnelType "L2tp" -AuthenticationMethod Chap,MSChapv2,Pap -L2tpPsk "<your-psk>"
or create script for it so you don't need to remmer all that options.
Then all what you need to do is call your script:
.\add-l2tp.ps1 -name "My VPN" -server "vpnserver.example.com" -psk "mySu9erS3cr3tPSK"
