The examples in these NAT type sections describe NAT translation between internal (private) and external (public) IP addresses.

12.11.2.1 Full Cone NAT

In full cone NAT, the NAT router maps all outgoing packets from an internal IP address and port to a single IP address and port on the external network. The NAT router also maps packets coming to that external IP address and port to the internal IP address and port.

In the following example, the NAT router maps the source address of all packets sent from the Prestige’s internal IP address 1 and port A to IP address 2 and port B on the external network. The NAT router also performs NAT on all incoming packets sent to IP address 2 and port B and sends them to IP address 1, port A.
