GOAL:
What is a Network address translation
FIX:
Network address translation is a method of mapping one or more private, reserved IP addresses to one or more public IP addresses.
NAT was defined to conserve IPv4 address space and refer to a specific block of IP addresses that are never recognized or routed on the Internet.
It allows organizations to use their own internal IP addressing scheme.
A NAT device translates between internal and external addresses, and is usually combined with proxy services.
NAT devices are implemented in firewalls to support the private addressing scheme as defined in RFC 1918.
