Chapter 1 Information About NAT
How NAT is Implemented
To start configuring twice NAT, see Chapter 34, "Configuring Twice NAT."
Figure 1-11 shows a host on the 10.1.2.0/24 network accessing two different servers. When the host
accesses the server at 209.165.201.11, the real address is translated to 209.165.202.129. When the host
accesses the server at 209.165.200.225, the real address is translated to 209.165.202.130.
