To follow along with the examples provided in this chapter, you will need two fully functional pfSense firewalls (with one or more nodes behind each firewall), either on real physical networks or in a lab/virtualization environment. Installation and configuration of the ShrewSoft VPN client, described in the section on IPsec, requires a system running Microsoft Windows (Windows 2000, XP, Vista, 7, 8, or 10 will do). The examples presented in this chapter should not be particularly resource-intensive; however, setting up an encrypted VPN tunnel does tax the CPU somewhat. Therefore, running pfSense on hardware that barely meets the minimum specifications for pfSense is not recommended.

Overview of this book
pfSense has the same reliability and stability as even the most popular commercial firewall offerings on the market – but, like the very best open-source software, it doesn’t limit you.
You’re in control – you can exploit and customize pfSense around your security needs.
Mastering pfSense - Second Edition, covers features that have long been part of pfSense such as captive portal, VLANs, traffic shaping, VPNs, load balancing, Common Address Redundancy Protocol (CARP), multi-WAN, and routing. It also covers features that have been added with the release of 2.4, such as support for ZFS partitions and OpenVPN 2.4. This book takes into account the fact that, in order to support increased cryptographic loads, pfSense version 2.5 will require a CPU that supports AES-NI.
The second edition of this book places more of an emphasis on the practical side of utilizing pfSense than the previous edition, and, as a result, more examples are provided which show in step-by-step fashion how to implement many features.
