Can ping from router but unable to ping from client machines

Hi All,

I am having a weird issue with my Cisco 7200 router. From the router i am able to ping and reach out to the internet but from the client i am able to reach out to the internet but unable to ping I am not sure where is the issue but when i traceroute to it my packets are dropped at my routers interface. All my pings from the client time out. I checked the Access list to make sure ICMP is not blocked.

Following is my running conf

ip audit notify log

Hi,

can you please specify which subnet belongs to the client.

In addition i dont see any config relating to NAT in your router.

Thanks

Thanks for replying. Ours is a very small environment and we use public IP's for clients too thats why there is no NAT related config. The running config i have posted above is real but i have replaced public IP's with private IP's.

Router subnet: 192.168.1.1/28

Client subnet: 192.168.10.1/24

Did you see anything in the Access list which might be causing this issue?
