In this chapter we will learn how to make the example tunnels we created safer and persistent by choosing a safe combination of configuration file parameters. We will then discuss how to install and use a firewall with a convenient web-based configuration interface on a standard Linux system, namely Shorewall on a Debian system. After that we will have a look at the SuSEfirewall 2 that comes with OpenSuSE. A short look will deal with how to configure the Windows XP firewall for use with OpenVPN. Last but not least, we will discuss the possibilities that the Linux command line offers (especially with the examples that come with OpenVPN).

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.
