Setup an IKEv2 server with strongSwan

IKEv2, or Internet Key Exchange v2, is a protocol that allows for direct IPSec tunnelling between two points. In IKEv2 implementations, IPSec provides encryption for the network traffic. IKEv2 is natively supported on some platforms (OS X 10.11+, iOS 9.1+, and Windows 10) with no additional applications necessary, and it handles client hiccups quite smoothly.
