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 static DHCP mappings

This recipe describes how to add a static (IPv4) DHCP mapping in pfSense. A static mapping ensures that a client always receives the same IP address from the DHCP server.

Getting ready

In order to create a static DHCP mapping, you must have at least one interface on which the DHCP server is enabled. (You can only create static DHCP mappings on interfaces using the DHCP server).

How to do it...

There are two ways of creating a static DHCP mapping.

  1. Navigate toServices | DHCPand click on theLANtab, if it isn’t selected already.
  2. Scroll to the bottom of the page. Beneath the Save button, there should be a section labeled DHCP Static Mappings for this Interface. Click on the Add button beneath this section:
  1. You are now in the Edit Static Mapping page. Enter a MAC address in the MAC Address edit box:
  1. In theIP Addressedit box, enter an IP address that is outside of the range of dynamically assigned IP addresses for this interface.
  2. In the Hostname edit box, enter the host...
