Configuring Static NAT
Let us start with Router0.
Router0(config)#interface Gi0/1
Router0(config-if)#ip address 192.168.1.1 255.255.255.0
Router0(config-if)#no shutdown
Router0(config-if)#ip nat inside
Router0(config-if)#interface Gi0/0
Router0(config-if)#ip address 2.2.2.1 255.255.255.0
Router0(config-if)#no shutdown
Router0(config-if)#ip nat outside
Router0(config-if)#exit
Router0(config)#ip nat inside source static 192.168.1.2 2.2.2.3
Configure Gi0/0 interface in Router1.
Router1(config)#interface Gi0/0
Router1(config-if)#ip address 2.2.2.2 255.255.255.0
Router1(config-if)#no shutdown
Check NAT translations in Router0.
Router0#show ip nat translations
For testing, ping 2.2.2.2 from PC0 (192.168.1.2). The ping will be successful. PC1 still can't ping 2.2.2.2.
Check NAT translations in Router0.
Router0#show ip nat translations
Router0(config)#ip nat inside source static 192.168.1.3 2.2.2.4
Now, PC1 (192.168.1.3) will be able to ping 2.2.2.2 successfully.
You can check translation in Router0.
Router0#show ip nat translations
