Openvpn
From James's Wiki
Working with systemd
With the transition to systemd, OpenVPN no longer has a single monolithic init script, where every connection with a configuration file in /etc/openvpn/ is started automatically. Instead, individual connections can be started and stopped with systemctl.
For example, to start a connection, run systemctl start openvpn@foo.service, where the connection is defined in /etc/openvpn/foo.conf.
