Configuration of NAT Pool
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 pool nat-pool-lab1 2.2.2.3 2.2.2.10 netmask 255.255.255.0
Router0(config)#ip nat inside source list 5 pool nat-pool-lab1
Router0(config)#access-list 5 permit 192.168.1.0 0.0.0.255
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
For testing, ping 2.2.2.2 from PC0 (192.168.1.2) and PC1 (192.168.1.3). The ping will be successful.
