Chapter 26 Information About NAT
How NAT is Implemented
Figure 26-16 shows a remote host connecting to a translated host. The translated host has a twice static
NAT translation that translates the real address only for traffic to and from the 209.165.201.0/27
network. A translation does not exist for the 209.165.200.224/27 network, so the translated host cannot
connect to that network, nor can a host on that network connect to the translated host.
