Network Security with pfSense

By: Manuj Aggarwal

Overview of this book

While connected to the internet, you’re a potential target for an array of cyber threats, such as hackers, keyloggers, and Trojans that attack through unpatched security holes. A firewall works as a barrier (or ‘shield’) between your computer and cyberspace. pfSense is highly versatile firewall software. With thousands of enterprises using pfSense, it is fast becoming the world's most trusted open source network security solution. Network Security with pfSense begins with an introduction to pfSense, where you will gain an understanding of what pfSense is, its key features, and advantages. Next, you will learn how to configure pfSense as a firewall and create and manage firewall rules. As you make your way through the chapters, you will test pfSense for failover and load balancing across multiple wide area network (WAN) connections. You will then configure pfSense with OpenVPN for secure remote connectivity and implement IPsec VPN tunnels with pfSense. In the concluding chapters, you’ll understand how to configure and integrate pfSense as a Squid proxy server. By the end of this book, you will be able to leverage the power of pfSense to build a secure network.

Using pfSense as a Squid Proxy Server

In the previous chapter, you got familiar with the IPsec protocol, and you also learned how to implement IPsec tunnels on the pfSense platform. In this chapter, you will learn how to configure pfSense as a Squid proxy server. You will be integrating the Squid Proxy into pfSense, and then testing it using client access.

Here are some of the key learning objectives of this chapter:

  • You will learn all about proxy servers, what they are, and their key features
  • You'll also get an understanding of the advantages of a Squid proxy server
  • You'll go through a series of demonstrations that will give you a practical insight into installing and configuring the Squid proxy server
  • You will learn how to test the Squid proxy server in a client environment

Let's kick this module off by understanding what a proxy server is.
