Lets start with basic config - from router you able to ping 8.8.8.8 ?

no ip nat pool 1 192.168.1.0 192.168.1.254 netmask 255.255.255.0
no ip nat inside source route-map track-primary-if interface GigabitEthernet0/0/0 overload
no ip nat outside source list 100 pool 1

access-list 1 permit 192.168.1.0 0.0.0.255

 

interface GigabitEthernet0/0/0 (wan dhcp)
ip address dhcp hostname R1
ip nat outside
no ip access-group 100 out
negotiation auto
spanning-tree portfast disable
!
interface GigabitEthernet0/0/1
ip address 192.168.1.1 255.255.255.0
ip nat inside
no ip access-group 100 in
negotiation auto
no mop enabled
spanning-tree portfast disable

then configured client with 192.168.1.X 255.255.255.0 and gateway 192.168.1.1

DNS 8.8.8.8 (or provider DNS and test and let us know)

Add this 

Ip nat inside list 1 interface g0/0/0 overload 

That it

I suggest add below 

Ip nat inside source  list 1 interface g0/0/0 overload 

You add different 

ip nat inside source route-map track-primary-if interface GigabitEthernet0/0/0 overload

??

Add what I suggest and remove not correct NAT

MHM

give me error when i try add

josecervini_0-1719354911606.png

 

I remove old line and add suggestions line, still same, not ping 8.8.8.8, 1.1.1.1, 8.8.4.4

Hi friend 
after you add 

Ip nat inside source  list 1 interface g0/0/0 overload  <<- it mandatory 


GigabitEthernet0/0/0 68.191.34.244 YES DHCP down down <<- how this Down Down ?? and the interface get IP via ISP DHCP ?

can you shut/ no shut and ping again form router to 8.8.8.8

MHM

Hi, yes is dhcp and not ping anyway

can you again do 
no shut <<- under g0/0/0
and check ping again 

MHM

I did no shut and try ping 8.8.8.8 but still same

This is my brief

Gig0/0/0 68.191.34.244 yes dhcp up up

 

Now ping from router to 8.8.8.8 it must be success 
then add 

Ip nat inside source  list 1 interface g0/0/0 overload  <<- it mandatory 

and try ping from client connect to g0/0/1

MHM

Ok, I add line, save conf, un shut into 0/0/0 but still not ping 8.8.8.8, also from client try ping g0/0/0 and 8.8.8.8 but doesn't work, only ping 192.168.1.1,
