 Hello and welcome to my course titled
 A Beginner's Guide to Nat.

0:00:12.780000 --> 0:00:16.220000
 My name is Keith Bogart and I will
 be your instructor for this series

0:00:16.220000 --> 0:00:19.720000
 of videos. Should you have any questions
 that are not answered by these

0:00:19.720000 --> 0:00:22.280000
 videos, please feel free
 to reach out to me.

0:00:22.280000 --> 0:00:24.960000
 You can see on the slide all
 my contact information.

0:00:24.960000 --> 0:00:26.540000
 I'd love to hear from you.

0:00:26.540000 --> 0:00:29.620000
 So what are we going to talk about
 in this beginner's guide to Nat?

0:00:29.620000 --> 0:00:33.700000
 Well, my objectives are very simply
 to help you gain familiarity with

0:00:33.700000 --> 0:00:37.340000
 the concepts and essential configuration
 commands for various forms of

0:00:37.340000 --> 0:00:41.920000
 NAT. So there's the forms of NAT we're
 going to talk about are static

0:00:41.920000 --> 0:00:47.340000
 NAT, dynamic NAT, and port address
 translation, otherwise known as NAT

0:00:47.340000 --> 0:00:51.980000
 overloading. So we're going to start
 with an overview of what is NAT,

0:00:51.980000 --> 0:00:55.160000
 what problem does it solve, and then
 we'll go into each of those three

0:00:55.160000 --> 0:00:58.420000
 different forms and we'll talk about how
 they're different from each other,

0:00:58.420000 --> 0:01:01.720000
 how you actually configure them, and
 I'll give you a demonstration on

0:01:01.720000 --> 0:01:05.500000
 all of them. Now as far as this course
 is concerned, there's very few

0:01:05.500000 --> 0:01:08.840000
 prerequisites that you need to meet,
 but there are a couple of things

0:01:08.840000 --> 0:01:12.340000
 that if you don't know them, well, this
 course might be a little confusing

0:01:12.340000 --> 0:01:16.440000
 to you. So really, the main thing I
 want you to know is an understanding

0:01:16.440000 --> 0:01:21.620000
 of how IPv4 addresses are used in
 routers in the routing of packets.

0:01:21.620000 --> 0:01:26.740000
 You see, the whole concept of NAT deals
 with IP and it deals with what

0:01:26.740000 --> 0:01:29.660000
 a router can do with an IP packet.


0:01:29.660000 --> 0:01:32.300000
 And if you don't understand the concept
 of IP, if you don't understand

0:01:32.300000 --> 0:01:37.280000
 the concept of IP addresses, this whole
 thing about NAT won't make a lot

0:01:37.280000 --> 0:01:37.940000
 of sense to you.

0:01:37.940000 --> 0:01:41.080000
 So hopefully you already know
 that coming into this course.

0:01:41.080000 --> 0:01:45.340000
 So let's go ahead and get going and
 learn about the basics of network

0:01:45.340000 --> 0:01:46.820000
 address translation.
