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.

Creating an NPt entry

This recipe will describe how to create an NPt entry. NPt, or Network Prefix Translation, allows you to map one IPv6 prefix to another. It is similar to 1:1 NAT, except that with IPv6, translation is more often used with entire prefixes and not single IP addresses.

How to do it...

  1. Navigate to Firewall | NAT.
  2. Click on the NPt tab.
  1. Click on one of the Add buttons to add a new entry.
  2. Choose the appropriate interface in the Interface drop-down menu (you can usually leave this set to WAN):
  1. In the firstAddresstext field, enter the internal IPv6 prefix, and select the correct CIDR in the corresponding drop-down menu.
  2. In the second Address edit box, enter the external IPv6 prefix, and select the correct CIDR in the corresponding drop-down menu.
  3. Enter a brief description in the Description text field.
  4. When you are done making changes, click on the Save button.
  5. Click on the Apply Changes button.

How it works...

NPt enables you to map an internal IPv6 prefix to an external one. It should...
