Re: What is NAT?

Can someone please (without asking me to Google) explain simply and
plainly what NAT is?

Is it, basically, the mechanism that my router uses to forward TCP or
UDP packets that come in to my router from the ISP to a specific machine
on my internal network (and vice-versa)?

Not really, although NAT is typically used in a router for that purpose.

NAT is an acronym for "Network Address Translation". With NAT, individual
nodes can have different IP addresses on one side of a router than they have
on the other side.

It is simply the mapping of an IP address to a new IP address.
