Does anyone have a tutorial on configuring a strongSwan (https://strongswan.org/) IPsec client on OpenWrt (https://openwrt.org/)? I'm running OpenWrt Chaos Calmer 15.05.1 with strongSwan 5.3.3-1 installed from the OpenWrt distribution packages. I have successfully tested an IPsec connection from a Windows 10 Enterprise system using Perfect Privacy VPN Manager behind this OpenWrt router. Example configuration files would be a good start. I have extracted the two certificates from the Perfect Privacy Cert Installer found on the Configuring IPSec/IKEv2 in Windows 10 page.
