Internet Gateways (IGWs) In Depth

All WinJoes know what an internet gateway is. Many affectionally refer to these as IGWs. But few know what these gateways do in amazing depth.

We aim to bridge that gap and confer, dare we say it, in-depth knowledge. We educate the new generation of "gateway gurus", or "IGW gurus".

So one question for you - NAT. How do IGWs interact with NATs - if at all? Does this differ in AWS versus other clouds? Exercise for the reader.

Basics of NAT

NAT refers to Network Address Translation.

NAT allows multiple devices in a private network to access the Internet using a single, public IP address. This results in a number of benefits, one being conservation of IP addresses (relevant for IPv4) and hides internal systems for added security.

Routers perform NAT to relay information between connected devices and the public Internet.
