Hello,

in addition to Tinashe's post, four basic things need to be configured: inside interface, outside interface, NAT access list, and NAT translation statement. Below is a sample:

interface FastEthernet0/0

description LAN 

ip address 192.168.1.1 255.255.255.0

ip nat inside

!

interface GigabitEthernet0/0

description WAN

ip address dhcp

ip nat outside

!

ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0 dhcp

!

ip nat inside source list 1 interface GigabitEthernet0/0 overload

!

access-list 1 permit 192.168.1.0

Hi

Could you please share a topology and configuration, additional to other members, the ICMP es reciprocal so you should have a path to return the response, so also verify the routing.

That isn't needed; he doesn't create a DHCP pool and even if he was, the IP address of the local interface is always excluded by default.
