pfSense 2.x Cookbook - Second Edition

By: David Zientara

Overview of this book

pfSense is an open source distribution of the FreeBSD-based firewall that provides a platform for ?exible and powerful routing and firewalling. The versatility of pfSense presents us with a wide array of configuration options, which makes determining requirements a little more difficult and a lot more important compared to other offerings. pfSense 2.x Cookbook – Second Edition starts by providing you with an understanding of how to complete the basic steps needed to render a pfSense firewall operational. It starts by showing you how to set up different forms of NAT entries and firewall rules and use aliases and scheduling in firewall rules. Moving on, you will learn how to implement a captive portal set up in different ways (no authentication, user manager authentication, and RADIUS authentication), as well as NTP and SNMP configuration. You will then learn how to set up a VPN tunnel with pfSense. The book then focuses on setting up traffic shaping with pfSense, using either the built-in traffic shaping wizard, custom ?oating rules, or Snort. Toward the end, you will set up multiple WAN interfaces, load balancing and failover groups, and a CARP failover group. You will also learn how to bridge interfaces, add static routing entries, and use dynamic routing protocols via third-party packages.

Configuring traffic shaping using floating rules

In this recipe, we will use floating rules to prioritize EchoLink traffic.

The previous recipe used the pfSense traffic-shaping wizard to prioritize Skype traffic and deprioritize BitTorrent traffic. Running the wizard essentially created the traffic-shaping queues as well as the floating rules. Once we have run the wizard, we have a second option for traffic-shaping: manually adding floating rules.

Getting ready

Completing this recipe requires having completed the previous recipe, Configuring traffic shaping using the traffic-shaping wizard recipe, or having run the wizard previously. Doing so will ensure the traffic shaping queues have been created.  

EchoLink is a program that allows amateur radio operators to communicate over a VoIP connection. It uses UDP on ports 5198 and 5199, and uses TCP on port 6000. In order to prioritize EchoLink traffic, we will create two rules (one for UDP traffic and the other for TCP traffic).
