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 dynamic DNS

This recipe describes how to configure a dynamic DNS service in pfSense. pfSense’s integrated dynamic DNS service allows you to update your dynamic DNS records automatically when you change an interface’s IP address.

Getting ready

In order to use the DNS service, you must first register with a DDNS provider. Some of the more common DDNS providers are listed in the Service Type drop-down box on the Dynamic DNS configuration page. A quick web search should yield a list of DDNS providers that meet any specific criteria you might have.

How to do it...

  1. Navigate toServices | Dynamic DNS.
  2. Click on the Dynamic DNS Clients tab, if it isn’t selected already.
  3. Click on the Add button to add a new record.
  4. Select a service type in the Service Type drop-down box (or choose Custom or Custom v6).
  1. Choose an interface in theInterface toMonitordrop-down box (or just leave it at the default value ofWAN).
  2. Specify the fully qualified hostname in the Hostname edit box.
  1. Check the Enable Wildcard checkbox...
