NAT on a Cisco ASA Firewall

Configuration and Verification of NAT on a Cisco ASA or ASAx Firewall

Course Summary

This course has two  modules:

Module 1:

The first 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.

Module 2:

The second module will step through the operation and behavior of each type of NAT. We'll configure a translate, set up packet captures, and show you the packet before and after translation.  This will 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.
