Mastering OpenVPN
Genres: Networking
Book Preface
Privacy and security on the Internet and in private networks is a growing concern and is increasingly common in the news, where there are breaches of each. Virtual private networks (VPN) were created out of a need for secured communications. The most popular and widely used open source VPN software today is OpenVPN. Mastering OpenVPN aims to educate you on deployment, troubleshooting, and configuration of OpenVPN and provide solid use cases for various scenarios.
What this book covers
Chapter 1, Introduction to OpenVPN, discusses the various types of Virtual Private Networks and some of their various strengths and weaknesses. PPTP, OpenVPN, IPSec, and other protocols are also discussed in this chapter.
Chapter 2, Point-to-point Mode, covers the OpenVPN roots, point-to-point mode, and the initially only supported mode. It also covers the tap mode in a bridged scenario and an uncommon configuration.
Chapter 3, PKIs and Certificates, explains the complex concept of X.509 certificates and PKIs with examples and a demonstration of a couple of utilities. It also covers how to create a certificate chain and deploy that chain to their VPN.
Chapter 4, Client/Server Mode with tun Devices, walks you through the most common deployment mode, a tun or routed, and its setup. It also discusses the passing of client-backed routes along with IPv4 and IPv6.
Chapter 5, Advanced Deployment Scenarios in tun Mode, covers policy-based routing and configuring OpenVPN to integrate your VPN clients with the rest of the LAN. Complex examples of tun mode are examined, showing that they are appropriate even in advanced scenarios.
