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.

Adding multiple WAN interfaces

In this recipe, we will add a multi-WAN setup to our pfSense firewall. This recipe will generate a gateway group with two WAN interfaces, although it could easily be altered to cover gateway groups with more than two WAN interfaces.

Getting ready

Adding multiple WAN interfaces makes the most sense when we have more than one internet connection. If you are completing this recipe in order to understand the process of configuring multiple WANs, and you have both a broadband and mobile internet connection, you can use these as your two connections. Otherwise, you will want to acquire two internet connections, preferably from two separate ISPs (otherwise, if you acquire two connections from the same ISP, then both connections to the internet will likely go down if your ISP experiences problems—hardly the redundancy and high availability we seek). If you have no choice but to use a single ISP, it might be helpful to obtain connections with different types of cabling...
