Overview
NAT is a feature that allows one set of IP addresses, typically private IP addresses, to be converted to
another set of IP addresses, typically public Internet IP addresses. This conversion is done transparently
by having a NAT device rewrite the source IP address and Layer 4 port of the packets.
