Configuring IPCop Firewalls: Closing Borders with Open Source

Overview of this book

IPCop is a powerful, open source, Linux based firewall distribution for primarily Small Office Or Home (SOHO) networks, although it can be used in larger networks. It provides most of the features that you would expect a modern firewall to have, and what is most important is that it sets this all up for you in a highly automated and simplified way. This book is an easy introduction to this popular application. After introducing and explaining the foundations of firewalling and networking and why they're important, the book moves on to cover using IPCop, from installing it, through configuring it, to more advanced features, such as configuring IPCop to work as an IDS, VPN and using it for bandwidth management. While providing necessary theoretical background, the book takes a practical approach, presenting sample configurations for home users, small businesses, and large businesses. The book contains plenty of illustrative examples.

We also need to look at the licenses those tools are distributed under, and therefore the IPCop license. This chapter will be less beneficial for those who would like to get straight to the installation and configuration and already know the background of open-source software, the GPL, and Linux. We will, however, also look at the reasons to choose IPCop in this chapter and the unique features it has, which will be useful when deciding whether to or how to deploy IPCop. It is, therefore, extremely important.

Commercial software, generally, comes with a license restricting you to use the software...
