VPN to every home

Hello! The desire to make the VPN server as simple as possible to install and convenient to use has been brewing for a long time. I took L2TP / IPsec as a basis, this technology is natively supported by all devices and, unlike PPTP, does not cause problems when connecting via cellular operators.

tl; dr
For installation, we need a machine with Ubuntu 14.04 on board and a "white" IP address, any VPS will do. Just enter this magic line:

 curl -sS https://raw.githubusercontent.com/sockeye44/instavpn/master/instavpn.sh | sudo bash 

VPN (htt://ip-address:8080/) (instavpn -h).
