Check Point Firewall Administration R81.10+

By: Vladimir Yakovlev

Overview of this book

Check Point firewalls are the premiere firewalls, access control, and threat prevention appliances for physical and virtual infrastructures. With Check Point’s superior security, administrators can help maintain confidentiality, integrity, and the availability of their resources protected by firewalls and threat prevention devices. This hands-on guide covers everything you need to be fluent in using Check Point firewalls for your operations. This book familiarizes you with Check Point firewalls and their most common implementation scenarios, showing you how to deploy them from scratch. You will begin by following the deployment and configuration of Check Point products and advance to their administration for an organization. Once you’ve learned how to plan, prepare, and implement Check Point infrastructure components and grasped the fundamental principles of their operation, you’ll be guided through the creation and modification of access control policies of increasing complexity, as well as the inclusion of additional features. To run your routine operations infallibly, you’ll also learn how to monitor security logs and dashboards. Generating reports detailing current or historical traffic patterns and security incidents is also covered. By the end of this book, you'll have gained the knowledge necessary to implement and comfortably operate Check Point firewalls.

Chapter 10: Working with Network Address Translation

While commonly referred to as Network Address Translation (NAT), this term covers both NAT and Port Address Translation (PAT). In this chapter, we will learn how to use NAT (and PAT) to ensure that our traffic can reach its destinations. We will explore both automatic and manual NAT options. Additionally, we will see when the use of static or dynamic NAT is appropriate and look at a few specific cases where additional configuration in Gaia might be required to achieve the desired address translation. As you read about various configuration examples, you’ll be instructed to either apply the relevant ones to our lab or not, for those that are used for demonstration and explanation. While NAT is a universal subject in networking, it is important to understand Check Point’s implementation specifics.

In this chapter, we are going to cover the following main topics:

  • The need for NAT
  • NAT policies, rules, and...
