Hello

The router may be prohibiting Icmp (ping)

Hi Amit,

Do 'debug IP icmp' on the source and destination router will help you find the problem.

In addition to what others have stated, also make sure the 192.168.2.0/24 subnet has a route to get back here. Sourcing the ping from a subnet that the 192 subnet knows about could resolve the issue....

Hi Amit,
This is something I learned on a CCNP course recently, Traceroute actually uses UDP not ICMP on certain Unix like systems. Worth checking if you've got an access list preventing this.
Cheers
