I have just finished (well for now still have more to add in the future), BBHN-Pi-VPN for the Raspberry Pi. It is re-branding of HSMM-Pi but with VPN settings added in the web UI. I also have started tutorials and hope to have videos on how to set up a Raspberry-Pi. I also hope to have a copy of a SD card image to make it even easier to setup.
It is available on Github https://github.com/bwattendorf/bbhn-pi-vpn
