When you are on the router, can you ping 8.8.8.8?

ping 8.8.8.8

if this is successful, can you ping using the source interface

ping 8.8.8.8 source 10.10.10.1

Also, what is the output of "sh ip nat trans"?

hi

i have erased all the configs and then redone to clear up the router.

INT fa0/0 connects to my ISP modem and gets DHCP from the modem and has IP of 192.168.0.33

Int fa0/1 is my private IP of 10.10.10.1 and connects to my laptop.

I can not ping 8.8.8.8 but i can ping FQDN like bbc.co.uk

i have taken ip nat enable and left only IP nat outside .

please find the current running config along with IP nat trans and result of ping to 8.8.8.8 and then bbc.co.uk

i hope that it enables you to help me.

Typically, there is no "normal" reason for ping 8.8.8.8 to fail if ping to 194.168.4.100 was successful (typical reason for cases like this is traffic filtering or black hole routing).

Reza Sharifi asked you for results of ping 8.8.8.8 source 10.10.10.1 to check NAT, it is pointless if ping to 8.8.8.8 from WAN port is not successful. You can try ping 194.168.4.100 source 10.10.10.1 if it is successful, most likely setting of this device are OK.

You can also test traceroute to both IP addresses:
traceroute 8.8.8.8
traceroute 194.168.4.100

Hi

i tried that while connected to my ISP through there modem using CMD and ping to 8.8.8.8 fails while ping to 8.8.4.4 is ok

ping to 8.8.4.4 through 10.10.10.1 is 100 % success.

May be I need to check with my isp the reason.

thanks

Hi

thanks to all got it working. Thanks 

Out of curiosity: how ? By putting the ISP modem in bridge mode ?

I had to uncheck the option of blocking fragment IP on modem.

Changing the modem into bridge mode didn't help.

Also I had to open ports from 1 to 65536 on my isp modem ,there is full connectivity but still ping to 8.8.8.8 doesn't work.

i hope it helps.

 Thanks 

When you do a traceroute to 8.8.8.8, where does it stop?

No idea the ping just fails,no reply from dns server.

What about:

?
