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.

Traffic shaping examples

In the section covering traffic shaping essentials, we discussed an example network with four subnets - developers, engineering, sales, and DMZ - as well as some basic traffic shaping requirements. Now, we will attempt to implement traffic shaping using pfSense in a manner that matches these requirements as closely as possible.

Example 1 – adding limiters

Although it is generally recommended that you use the traffic shaper wizards when getting started with traffic shaping, for this exercise we will avoid using them, since the rules the wizard will implement would require significant modification. We will begin by navigating to Firewall | Traffic Shaper and selecting the Limiters tab.
