Packt Publishing has come up with a book titled, "OpenVPN: Building and Integrating Virtual Private Networks", authored by Markus Feilner. This book is a comprehensive guide to using OpenVPN for building both secure VPNs. The book is written in a very friendly style that makes this complex topic easy and a joy to read. It first covers basic VPN concepts, then moves to introduce basic OpenVPN configurations, before covering advanced uses of OpenVPN. This book is for both experienced and new OpenVPN users. This book is an easy introduction to this popular VPN application. After introducing the basics of security and VPN, the book moves on to cover using OpenVPN, from installing it on various platforms, through configuring basic tunnels, to more advanced features, such as using the application with firewalls, routers, proxy servers, and OpenVPN scripting. While providing only necessary theoretical background, the book takes a practical approach, presenting plenty of examples. It also has a documentation of Installing OpenVPN on Debian other than installing it on Windows, Mac, SuSE Linux, Redhat Fedora using yum, RPM-based Systems, and FreeBSD.
