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 a stand-alone DHCP/DNS server

This recipe describes how to configure pfSense as a stand-alone DHCP and DNS server.

How to do it...

  1. Configure pfSense as a DHCP server. See theConfiguring the DHCP serverrecipe for details.
  2. Create DHCP mappings for every device in the system that will obtain its IP address automatically through DHCP. See the Creating static DHCP mappings recipe for details.
  1. Navigate to System | General Setup.
  1. Ensure that no other DNS servers are specified.
  2. Check the Allow DNS server list to be overridden by DHCP/PPP on WAN checkbox. This will enable pfSense to resolve external addresses using the DNS servers provided by your ISP through your WAN connection.
  3. Click on the Save button.
  4. Navigate to System | DNS Resolver.
  5. Check the Enable DNS Resolver checkbox.
  1. Check the Register DHCP static mappings in the DNS Resolver checkbox.
  1. Create aHost recordfor any device that needs to be resolved but doesn’t have a DHCP mapping (that is, devices that define their own IP).
  2. Create a Domain...
