This is a guide on setting up an IPSEC/L2TP vpn server with Ubuntu 14.04 using Openswan as the IPsec server, xl2tpd as the l2tp provider and ppp or local users / PAM for authentication. It has a detailed explanation with every step. We choose the IPSEC/L2TP protocol stack because of recent vulnerabilities found in pptpd VPNs and because it is supported on all major operating systems by default. Why a VPN? More than ever, your freedom and privacy when online is under threat. Governments and ISPs want to control what you can and can't see while keeping a record of everything you do, and even the shady-looking guy lurking around your coffee shop or the airport gate can grab your bank details easier than you may think. A self hosted VPN lets you surf the web the way it was intended: anonymously and without oversight. A VPN (virtual private network) creates a secure, encrypted tunnel through which all of your online data passes back and forth. Any application that requires an internet connection works with this self hosted VPN, including your web browser, email client, and instant messaging program, keeping everything you do online hidden from prying eyes while masking your physical location and giving you unfettered access to any website or web service no matter where you happen to be at the moment. This tutorial is available for the following platforms: Raspberry Pi with Arch Linux ARM CentOS 6, Scientific Linux 6 or Red Hat Enterprise Linux 6 Ubuntu 14.04 LTS Ubuntu 13.10 Ubuntu 13.04 Ubuntu 12.10 Ubuntu 12.04…

Author: DigitalOcean Intro One of the commonly asked questions from our users is how to add another IP address to their server. You can assign your own private IP address to your droplet by creating a VPN tunnel. Whether you want to build your own Virtual Private Network (VPN), or assign an SSL certificate to that IP address, you have several options. From all of the possible options, the most optimal ones are between PPTP and OpenVPN. A Point-To-Point Tunneling Protocol (PPTP) allows you to implement your own VPN very quickly, and is compatible with most mobile devices. Even though PPTP is less secure than OpenVPN, it is also faster and uses less CPU resources.
