The best way to trace a particular IP is throught the use of the capture statement... First, you define an ACL to look for the specific traffic you are interested in. Then, you assign your ACL to a cap and applyt he capture to the interface you want. Here is an example:

access-list cap extended permit ip host host

capture cap access-list cap interface outside

hi walker,

The destination of the traffic is to the internal router.

interested in both.we are using this pix only for nating,asa5510.

Here you go...

access-list cap1 extended permit ip any host's public IP)

access-list cap1 extended permit ip host any

access-list cap2 extended permit ip any host (router's internal IP)

access-list cap2 extended permit ip host any

capture cap1 access-list cap1 interface outside

capture cap2 access-list cap2 interface inside

To see captures..

show capture cap1

show capture cap2

********* PLEASE RATE***************
