I configured my routers as described on the cisco's webpage (http://www.cisco.com/warp/public/707/manual.html) to make my two routers communicating IPSEC. I saw the same config when I wrote "sh run..." on the two routers but I could not succeed in seeing the ESP packets in between while one end host pinging otherside, rather I saw normal ping packets. So I wonder do I miss some point in configuration? What else should I do more to establish a "working" IPSEC connection between two routers? Thanks a lot for your help.
