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.

Configuring the L2TP VPN service


This recipe describes how to set up pfSense as a L2TP VPN server.

Getting ready

It’s important to understand that unlike the other VPN implementations, L2TP does not encrypt any data. L2TP is simply a method of encapsulation and should only be used over trusted networks, or in conjunction with IPsec. A major advantage of L2TP, however, is that it can be used with non-IP networks.

Note

Networks connected through VPN must use different subnets. For example, if both networks use the 192.168.1.0/24 subnet, then VPN will not work.

How to do it...

  1. Browse to VPN | L2TP.

  2. On the Configuration tab, check Enable L2TP Server.

  3. Specify an unused IP for the Server address.

  4. Specify an unused starting IP for the Remote address range. The range will be as long as the number of users specified in step 6.

  5. Specify a Subnet mask.

  6. Specify Number of L2TP users:

  7. Save the changes.

  8. Click the Users tab.

  9. Click the “plus” button to create a new user.

  10. Specify a username and password:

  11. Save the changes...
