Background

The information by the School of Science is outdated/wrong.
"Seems there is no easy way anymore to establish a L2tp VPN connection since OpenSwan has been deprecated and removed in Ubuntu 14.10". However: "A PPA exists now for network-manager-l2tp"
(https://askubuntu.com/questions/617785/how-to-connect-to-l2tp-over-ipsec-vpn)
