I tried to lab the doc. published by Cisco on tracing route across ASA 7.2, but couldn't make it working. ICMP is working fine, I guess it is helpful to ensure reachability and nat translation.
Your help is appreciated.
The attached text file shows the output of ping and trace route at the R1; the source router, then the debug icmp trace at the ASA, finally the output for "debug ip packet detail" at the destination router.
