Network Address Translation - Cisco ASA and ASAx Firewalls

Requirements

  • Basic understanding of computer networks.

This course has three modules.

The first module will teach you Everything there is to know about Network Address Translation: Why it exists, How it it works, What happens to packets as they get translated. This module will explain every type of translation:  Static NAT, Static PAT, Dynamic PAT, and Dynamic NAT. You’ll learn about each of these in a way that is completely vendor agnostic — the concepts you learn here will apply to any vendor and any platform. You’ll then learn how these four types of translations are used in Policy NAT and Twice NAT.

The second module will teach you the Syntax and Configuration of every type of NAT. There are two ways to configure NAT on a Cisco ASA and ASAx Firewall, and those two ways are Auto NAT and Manual NAT. Both of these methods require the use of objects, so this module starts with by defining and configuring objects. Then we discuss Auto NAT, when to use it and how to configure it. Then we talk through Manual NAT and provide configuration examples of every type of NAT it can configure. That leads us into an illustration of NAT Exemption. Finally, we finally wrap up with a discussion on NAT precedence and the order in which NAT statements are evaluated by the ASA..

Lastly, the third module will circle back to the concepts learned in the first module, and actually prove and demonstrate every claim that was made about NAT. The goal of this course is not only to tell you how NAT works, but also to prove it to you so you can see it for yourself.
