Network address translation (NAT) is the process of modifying IP addressinformation in IP packet headers while in transit across a traffic routing device. There are two different types of NAT: NAT Static NAT: The simplest type of NAT provides a one-to-one translation of IP addresses. It is often also referred to as one-to-one NAT.
