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.

Bridging interfaces

This recipe will demonstrate how to bridge two interfaces on a pfSense firewall—the LAN and DMZ interfaces.

How to do it...

  1. Navigate to Interfaces | Assignments.
  2. Click on the Bridges tab.
  3. Click on the Add button.
  4. In the Member Interfaces list box, select LAN and DMZ:
  1. Enter a brief description in the Description text field (for example, LAN-DMZ bridge).
  2. Click on the Save button.
  1. We now have bridged the two interfaces, but unless the firewall rules allow traffic to flow between them, traffic will be blocked. Therefore, we will add firewall rules to allow traffic to flow between LAN and DMZ:
    1. Navigate to Firewall | Rules.
    2. Click on the LAN tab.
    3. Find the IPv4 default allow LAN to any rule and click...
