Beginning OpenVPN 2.0.9

I purchased this book hoping it would give me practical info in terms of how to set up an OpenVPN configuration for our small business. I have a pretty technical background - I have a computer science degree and worked for 10 years as a software engineer but have been away from the tech side of the business for a while. I needed more help configuring the system than the online resources provide. The book gives a pretty good (if not too long) background on what a VPN is and the pros and cons of different types of VPN solutions. That's not really what I needed when I purchased that book Unfortunately, when you get to the "how-to" section in chapter 7, the authors start with excruciating detail like "double click this file", then proceed to skip over huge, important concepts like how to assign or determine what should be the IP address of the Virtual Ethernet device. Those are the exact concepts that need to be explained - otherwise you could just go online and read the on-line guides that are available. This book turned out to be very disappointing.
