12.11.1 NAT Example

See the following figure. The Prestige (X) sends packets to the Internet. The Prestige’s IP address is 10.0.0.3 (a private IP address). The NAT router maps the private source IP address to a public source IP address (a.b.c.d).

Note: The NAT figures in this chapter use lower-case letters (like a.b.c.d for example) to represent public IP addresses.

Figure 20 NAT: Outgoing

When the NAT router receives packets with destination address IP address a.b.c.d, the NAT router changes a.b.c.d back to the private IP address 10.0.0.3 and sends it to the Prestige.

Figure 21 NAT: Incoming
