Scenario
Figure 10-9
Configuration
Steps
 Configure ip nat inside on the inside interface.
 Configure ip nat outside on the outside interface.
 Configure a dynamic NAT rule.
 Configure ALG.
A
A# configure terminal
A(config)# interface GigabitEthernet 0/0
A(config-if-GigabitEthernet 0/0)# ip address 192.168.12.1 255.255.255.0
A(config-if-GigabitEthernet 0/0)# ip nat inside
A(config-if-GigabitEthernet 0/0)# exit
A(config)# interface GigabitEthernet 0/1
A(config-if-GigabitEthernet 0/1)# ip address 200.168.12.1 255.255.255.0
A(config-if-GigabitEthernet 0/1)# ip nat outside
A(config-if-GigabitEthernet 0/1)# exit
A(config)# ip nat pool net200 200.168.12.2 200.168.12.100 netmask 255.255.255.0
A(config)# ip nat inside source list 1 pool net200
A(config)# access-list 1 permit 192.168.12.0 0.0.0.255
A(config)# ip nat translation ftp 23
Verification
Use the show command to display the configuration.

Common Errors
 The inside or outside interface is not configured.
 The ACL configuration is incorrect.

Networking
Requirements
For some advanced applications of NAT, the source addresses or destination addresses of some specific IP packets need
to be modified.
