NAT is designed for more than just obscuring IPs, and if IPSec is in use in this environment, it will negate the ability to use IPSec in transport mode. Without knowing why the OP isn't using NAT, it may not be feasible for his environment. Disallowing ICMP reply packets would achieve the requested result without requiring significant modification. Just my two cents.

Say a customer traces to any IP on internet he is able to map my private network also which I want to prevent. So how can I hide the private ip's in the traceroutes. I use cisco routers. Any suggestions are welcome.
