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.

First Boot


When the IPCop system boots up we will be shown the following screen, which is the boot loader installed as part of IPCop (Grub). We can now choose the boot option we want to use and optionally add any parameters to the kernel prior to boot. After a few seconds, the default entry should boot.

Note

Grub

Grub is one of the commonly used boot loaders for Linux, and it essentially intermediates between the computer's BIOS and the operating system, letting us choose multiple operating systems or just specify options for one (such as picking SMP or ACPI support rather than the standard kernel, as in the menu shown in the previous screenshot).

More information on Grub can be found on the FSF website.

We should then see some boot information output on the screen, which should last for a few seconds, followed by a satisfying set of happy beeps and finally the following output:
