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.

Using traceroute

Traceroute is a network diagnostic tool for displaying the route and measuring transit delays of packets across an IP network. The round-trip times of packets received from each host on the route is recorded. Each step in the route is called a hop, and the sum of the mean times of each hop is a measure of the total time taken to establish the connection. Thus, traceroute provides more detailed information than Ping, which only computes the final route-trip times from the destination.

This recipe describes how to use the traceroute utility in pfSense.

How to do it...

  1. Navigate to Diagnostics | Traceroute.
  1. In the Hostname text field, enter the hostname or IP address of the destination:
  1. In the IP Protocol drop-down menu, select IPv4 or IPv6.
  2. In the Source Address drop-down menu, select the interface that will be the source IP address of the traceroute operation (or leave it set to Any).
  3. In the Maximum number of hops drop-down menu, select the maximum number of hops to trace (1 to 64...
