Dynamic NAT is a feature which dynamically allocates an IP address to an incoming or outgoing flow. This address will replace source or destination IP for all packets of the flow. The new IP address given to the flow is from a pool of addresses called NAT pool. L4 port can also be replaced by a new one in case of NAPT (Network Address Port Translation). In address only NAT only the IP address is translated. NAPT is not supported in masquerade or overload mode.
