• sudo gedit /etc/NetworkManager/system-connections/Lab1

[connection]
id=Test
uuid=4f433af4-3f36-427b-8f68-897a70f02818
type=vpn
autoconnect=false

[vpn]
service-type=org.freedesktop.NetworkManager.pptp
gateway=10.10.10.10
user=xxx
password-flags=1
[ipv4]
method=auto

And modify the config file: add [vpn-secrets]
