2009.8.17 PIX/ASA 開traceroute

In the outside-in access-list (acl_out), make sure that the following
entries are present:

access-list acl_out permit icmp any any time-exceeded
access-list acl_out permit icmp any any unreachable
access-list acl_out permit icmp any any echo
access-list acl_out permit icmp any any echo-reply

I've seen the question asked hundreds of times, and since I finally
found how to do it without allowing ALL icmp, I thought I'd share.

Hope it helps!
