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.

  2. Adding L2TP users
  3. Adding an L2TP firewall rule

How to do it...

  1. Begin by enabling and configuring the L2TP server:
    1. Navigate to VPN | L2TP.
    2. Check the Enable L2TP server checkbox. The rest of the settings will appear.
    3. In the Server address edit box, enter the IP address the L2TP server should give to clients as the gateway. It should be an address just outside the range of addresses reserved for the clients. For example, if you plan to use to for client IP addresses, the server address could be
    1. In the Remote address range edit box, enter the starting IP address for the client IP address subnet. Select the correct CIDR in the adjacent drop-down menu.
    2. Select the appropriate number of users in the...
