L2TP over IPsec in Stretch Gnome Shell

[Jiri <j@ganomi.com>]

Hi all,

Any advise how to establish L2TP over IPsec VPN in Stretch. I installed 
strongswan network-manager packages, but when I go to network manager 
GUI and select strongswan as VPN the wizard shows me box for name only.

Any advise? Am I missing any packages?

Thanks
Jiri
