Mastering pfSense - Second Edition

By: David Zientara

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.

If you only have a few devices on your network, you could easily configure them with static IP addresses and not use a DHCP server at all. In such cases, internet connectivity will be established more quickly, since computers on the network won't have to go through the DHCP discovery-offer-request-acknowledge process. As the size of your network grows, however, a DHCP server becomes essential, as keeping track of statically assigned IP addresses will become far too cumbersome. Fortunately, configuring pfSense to act as a DHCP server is relatively easy, and can be done from either the console or the web GUI.
