Hi @moelsaid ,
I think it is necessary to configure the 192.168.20.0 network in an interface, besides, that interface must be left as ip nat inside.

hello @luis_cordova
thank you for your response but can you explain more, I'm kinda confused
thank you

Hi @moelsaid ,
You have the output interface configured (FastEthernet8).
You have the nat configured to translate the 192.168.20.0 network, but, you do not have that network configured in any interface.
In addition, you must indicate that this interface will be the input interface after the translation.
Maybe:
FastEthernet7
ip address 192.168.20.1 255.255.255.0
ip nat inside
Regards

hello @luis_cordova
I already did that on interface VLAN 1 and make to nat inside, Does the nat inside should be in phycial interface, not VLAN interface ??

Hi
No it can be either logical or physical depending on setup , you need an inside NAT and outside on the public interface , the modem connected must also be in bridge mode so it pulls the external IP address back onto the Cisco router and basically just becomes dumb terminal
example in this link ,with wireless config setup too

Hi @Hulk8647 ,
If the network 192.168.20.0 is in the interface vlan1, it is expected that the devices will be associated with that vlan.
Within the interface vlan1, you must indicate that this will be the input interface for the NAT:
interface vlan 1
ip address 192.168.20.1 255.255.255.0
ip nat inside
no shutdown
