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.

In recent years, Virtual Private Networks (VPNs) have come to play a key role in connecting to private networks over the public internet and connecting private networks at different locations to each other over the internet. They allow us to connect to private networks remotely and access resources as if they are local. At one time, such functionality was only available via private WAN circuits. Such circuits offer low latency and high reliability, but the high monthly costs make this option prohibitively expensive for many users.

Fortunately, we have the option of configuring a VPN. The downside of using a VPN, rather than a private WAN circuit, is that VPNs establish tunnels over the internet. As a result, they must be encrypted, and encrypting traffic requires processing power. Therefore, establishing and maintaining a VPN tunnel will require a system with more resources than the minimum pfSense specifications. This should be taken into consideration when selecting hardware...
