Hello people. I've been looking to learn about NAT but all the guides ive found are very long and go in depth; not so easy to read. Im sure its not that complicated. Can some nice person please explain it to me "in a nutshell"? Lets say I have a small LAN of about 3 pcs and a NAT/firewall pc connecting them to the internet. What commands would I need to run to set up network address translation so that those pcs could communicate with the outside world?
