DYNAMIC NAT -

IANA provided group of public ip addresses for
communication between stub network ( Internal N/w) to
Internet (outside) network.
Here we map dynamicaly public group Ip addresses with our
stub network ip addresses (private n/w).

OVERLOAD NAT

IANA provided single public ip address for communication
between stub network ( Internal N/w) to Internet (outside)
network.
Here we map dynamicaly public Ip address with our stub
network ip addresses (private n/w) by using source port
number for each pair.Each entry will have separate port
number to identify source/Destination.max ports can assign
4000.
