Overview of this book

OpenVPN provides an extensible VPN framework that has been designed to ease site-specific customization, such as providing the capability to distribute a customized installation package to clients, and supporting alternative authentication methods via OpenVPN’s plugin module interface. This book provides you with many different recipes to help you set up, monitor, and troubleshoot an OpenVPN network. You will learn to configure a scalable, load-balanced VPN server farm that can handle thousands of dynamic connections from incoming VPN clients. You will also get to grips with the encryption, authentication, security, extensibility, and certifications features of OpenSSL. You will also get an understanding of IPv6 support and will get a demonstration of how to establish a connection via IPv64. This book will explore all the advanced features of OpenVPN and even some undocumented options, covering all the common network setups such as point-to-point networks and multi-client TUN-style and TAP-style networks. Finally, you will learn to manage, secure, and troubleshoot your virtual private networks using OpenVPN 2.4.

Preface

Introduction


The recipes in this chapter will cover the most commonly used deployment model for OpenVPN: a single server with multiple remote clients capable of routing IP traffic.

We will also look at several common routing configurations in addition to the use of the management interface at both the client and server side.

The last recipe of this chapter will show how it is possible to avoid the use of network bridges for most practical use cases.

As a routed TUN-style setup is the most commonly used deployment model, some of the sample configuration files presented in this chapter will be reused throughout the rest of the book. In particular, the configuration files such as basic-udp-server.confbasic-udp-client.confbasic-tcp-server.conf, and basic-tcp-client.conf from the Server-side routing recipe will be reused often, as well as the Windows client configuration files basic-udp-client.ovpn and basic-tcp-client.ovpn from the Using an ifconfig-pool block recipe.
