Set up your own IPsec VPN server in just a few minutes, with both IPsec/L2TP and Cisco IPsec on Ubuntu, Debian and CentOS.
An IPsec VPN encrypts your network traffic, so that nobody between you and the VPN server can eavesdrop on your data as it travels via the Internet. This is especially useful when using unsecured networks, e.g. at coffee shops, airports or hotel rooms.
Scripts use Libreswan as the IPsec server, and xl2tpd as the L2TP provider.
Quick start
First, prepare your Linux server with a fresh install of Ubuntu LTS, Debian or CentOS.
Use this one-liner to set up an IPsec VPN server:
wget https://git.io/vpnsetup -O vpnsetup.sh && sudo sh vpnsetup.sh
If using CentOS, replace the link above with https://git.io/vpnsetup-centos.
Your VPN login details will be randomly generated, and displayed on the screen when finished.
For other installation options and how to set up VPN clients, read the sections below.
