Network address translation (NAT) solves the problem of allowing a device with a non-routable, private IP address to get routed to the public Internet by allowing routers to manipulate the packet and segment headers. In this course, Network Address Translation (NAT) for Cisco CCNA 200-125/100-105, you'll learn all about how this works. First, you'll get an introduction to NAT, its history, and why it was developed. Next, you'll spend some time exploring the different types of NAT. Finally you'll learn how to implement and troubleshoot static NAT, dynamic NAT with overload, and port forwarding. By the end of this course, you will be able to implement all the different types of NAT in your environment.

Course Overview
Hi, everyone, my name is Ross Bagurdes and welcome to my course, Network Address Translation, or NAT. I am a network engineer with 20 years experience building and managing enterprise networks and teaching people about them. Network Address Translation, or NAT, is a mandatory feature on modern networks whether they are at home or in a small or large business. NAT is a method of modifying packet headers and segment headers to change the source and or destination IP address and port number as it moves through a router. NAT is used to bridge private networks addressed with private, unroutable IP addresses to the public internet. In this course, we'll learn about the different applications of NAT, including Static NAT, Dynamic NAT with overload, which is also called port address translation, or PAT, as well as Port forwarding. By the end of this course, you will be able to implement and troubleshoot NAT, PAT, PAT with port forwarding, as well as an approach to troubleshooting Network Address Translation by examining some common NAT configuration errors. Before beginning the course, you should be familiar with IP addressing, packet headers, TCP and UDP segments and their headers, Access Control Lists, as well as how packets are routed through a network, which all can be learned in the previous videos in this CCNA series. From here you should feel comfortable diving in to the last course of the ICND1 part of CCNA training called Building and Troubleshooting a network with ICND1 skills. I hope you'll join me on this journey to learn the different applications of NAT with the Network Address Translation course at Pluralsight.
