OpenVPN: Building and Integrating Virtual Private Networks

Overview of this book

OpenVPN is a powerful, open source SSL VPN application. It can secure site-to-site connections, WiFi and enterprise-scale remote connections. While being a full-featured VPN solution, OpenVPN is easy to use and does not suffer from the complexity that characterizes other IPSec VPN implementations. It uses the secure and stable TLS/SSL mechanisms for authentication and encryption. 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.

For this purpose, we can simply enter a new file name in the field File name using the file name extension .db. This is very important, because xca may not recognize the database correctly later if the extension is missing. Click on the Save button to commit the creation of the database.

Now we must define a password for this database. This password will be needed to encrypt the keys in the database file. If you transfer...
