Configuring Network Address Translation (NAT)
Planning the NAT Configuration
When you record the global address for destination NAT, identify the inside
device’s IP address as it appears in the destination network. For the sample
network, the Web server’s actual IP address is 192.168.1.25. You would,
therefore, record 192.168.1.25 as the global address.
Because the sample network is also using port address translation, you should
record the port for the translated traffic, as shown in Table 8-4.
