Dynamic NAT and PAT Implementation

For dynamic NAT and PAT, you first configure a nat command identifying the real addresses on a given
interface that you want to translate. Then you configure a separate global command to specify the
mapped addresses when exiting another interface (in the case of PAT, this is one address). Each nat
command matches a global command by comparing the NAT ID, a number that you assign to each
command (see

See the following commands for this example:
hostname(config)# nat (inside) 1 10.1.2.0 255.255.255.0
hostname(config)# global (outside) 1 209.165.201.3-209.165.201.10
