Explanation:

NAT has several forms:
Static NAT: Maps an unregistered or private IP address to a registered IP address; it is configured manually. It is commonly used to assign a network device with internal private IP address a unique public address so that they can be accessed from the Internet. Dynamic NAT: Dynamically maps an unregistered or private IP address to a registered IP address from a pool (group) of registered addresses. The two subsets of dynamic NAT are overloading and overlapping:
oOverloading: Maps multiple unregistered or private IP addresses to a single registered IP address by using different ports. This is also known as PAT, single-address NAT, or port-level multiplexed NAT.
oOverlapping: Maps registered internal IP addresses to outside registered IP addresses It can also map external addresses to internal registered addresses.
