Learn pfSense 2.4

By: David Zientara

Overview of this book

As computer networks become ubiquitous, it has become increasingly important to both secure and optimize our networks. pfSense, an open-source router/firewall, provides an easy, cost-effective way of achieving this – and this book explains how to install and configure pfSense in such a way that even a networking beginner can successfully deploy and use pfSense. This book begins by covering networking fundamentals, deployment scenarios, and hardware sizing guidelines, as well as how to install pfSense. The book then covers configuration of basic services such as DHCP, DNS, and captive portal and VLAN configuration. Careful consideration is given to the core firewall functionality of pfSense, and how to set up firewall rules and traffic shaping. Finally, the book covers the basics of VPNs, multi-WAN setups, routing and bridging, and how to perform diagnostics and troubleshooting on a network.

Traffic Shaping

Regardless of the size or purpose of your network, and regardless of your budget, you will derive benefits from optimizing the performance of your network. You have already taken a step in the right direction by learning about pfSense and, in previous chapters, we discussed some ways to improve performance, such as setting up our own DNS server and optimizing firewall rules. Another way to improve performance is to enable traffic shaping on our network. Without traffic shaping, network traffic is processed on a first-in, first-out (FIFO) basis. While, in some cases, this form of traffic management is adequate, it is far from optimal, and can lead to connections becoming saturated, which, in turn, causes buffering and increased latency. Traffic shaping, also known as quality of service (QoS), is a form of bandwidth management in which network traffic is made to...
