pfSense 2 Cookbook

Overview of this book

pfSense is an open source distribution of FreeBSD-based firewall that provides a platform for flexible 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. Through this book you will see that pfSense offers numerous alternatives to fit any environment's security needs. pfSense 2.0 Cookbook is the first and only book to explore all the features of pfSense, including those released in the latest 2.0 version. With the help of step-by-step instructions and detailed screenshots of the pfSense interface you will be able to configure every general and advanced feature from creating a firewall rule to configuring multi-WAN failover. Each recipe includes tips and offers advice on variations of the topic or references to other related recipes and additional information that can be found from other sources. pfSense 2.0 Cookbook covers the gamut of available features and functionality. The first three chapters will take you from a non-existent system to a basic pfSense firewall. The next chapter focuses on configuring any number of the VPN services available, a very important and sought-after feature for anyone implementing a firewall. The following two chapters describe how to configure the most advanced features available in pfSense; features that may only be relevant to the most experienced network admins. Chapter 7 is dedicated to understanding and configuring the "grab-bag" of features that are available in pfSense, but are often stand-alone options and unrelated to each other. The first appendix explains how to use the status monitoring tools available for many of the features. The second appendix wraps up with helping you to decide how and where pfSense may be incorporated into your system and what type of hardware is required based on your throughput needs.

Enabling OpenNTPD


The OpenNTPD service will serve date and time requests to clients that request them. This recipe describes how to enable the OpenNTPD service in pfSense.

How to do it...

  1. Browse to Services | OpenNTPD.

  2. Check Enable to enable the NTP daemon service.

  3. Select the interface(s) the NTP daemon service will listen on.

  4. Save the changes.

How it works...

OpenNTPD is an open-source implementation of the Network Time Protocol service. Devices within your network can now query the pfSense firewall with NTP and receive accurate time data from it.

Note

Client machines can take a few hours to become fully synchronized with the OpenNTPD service. Be patient.
