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 DHCP server

This recipe describes how to configure the DHCP server. The DHCP server assigns an IP address to anyone who requests one.

Getting ready

In order to enable the DHCP server on an interface, that interface must have a static IP address. If you have followed the recipes in order, you should have at least one interface with a static IP address (the LAN interface). This example will show how to configure the DHCP server on the LAN interface.

How to do it...

  1. Navigate toServices | DHCP Server.
  2. Click on the LAN tab, if it isn’t selected already.
  3. Under General Options, check the Enable DHCP server on LAN interface checkbox:
  1. In theRangeedit boxes, enter a range of IP addresses for the DHCP server to assign to clients. The range must be contiguous and within the range listed next toAvailable range.
  2. If you do not need more than a single range of IP addresses, proceed to Step 6. Otherwise, perform the following steps to add multiple IP address pools:
