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 the IPsec OpenVPN server – peer-to-peer

In this recipe, we will configure the IPsec server to connect to another IPsec server (peer-to-peer).

The purpose of this recipe is to set up an IPsec VPN tunnel that is similar to a tunnel we might set up if we wanted to connect two private networks separated by a considerable distance, as would be the case if we had networks in separate facilities. For example, we might have to connect a company’s headquarters with a satellite office. Fortunately, there are pfSense firewalls at the boundary of each network. The endpoint for each tunnel will be the WAN interface of each firewall.

In order to set up this VPN tunnel, we must complete several steps:

  1. Phase 1 and phase 2 configuration must be completed on the first firewall.
  2. Firewall rules must be added to allow VPN traffic to pass through the firewall.
  3. We must repeat the first two steps on the second firewall.

How to do it...

  1. Navigate to VPN | IPsec.
  2. On the default Tunnels tab, click on the Add P1...
