Click the sidebar link: "FAQs: NAT and VPN" for a poorly written

NAT is intrinsic to the operation of your router. It is
how one public address, is shared by the computers that
are plugged into the router. It maps public_address
ublic_port
to private_address
rivate_port. So port 13023 can go to
computer #1, port 15349 can go to computer #2, and so on.
The translation from public address to private address,
is your NAT function. It it was turned off, you wouldn't
have much of a router. If you had four public addresses
on the router (most ISPs don't like to do that), and four
connected computers, that would not help preserve the
limited number of public addresses (at least until IPV6
is the norm).
You can read this, for a better written description than
I can give.
