Types of NAT

• Static NAT. It is otherwise called balanced NAT.
• Dynamic NAT. In this kind of NAT, planning of IP from an unregistered private organization is finished with the single IP address of the enrolled network from the class of enlisted IP addresses.
• Overloading NAT.
• Overlapping NAT.
