ASA Config

//create an ACL that permits the incoming ICMP

access-list outside_access_in remark ICMP type 11 for Windows Traceroute
access-list outside_access_in extended permit icmp any any time-exceeded
access-list outside_access_in remark ICMP type 3 for Cisco and Linux
access-list outside_access_in extended permit icmp any any unreachable

//bind the ACL to the outside interface

access-group outside_access_in in interface outside

do you have a default service policy and class?

i.e. on the bottom of your running config do you have something like this...............

policy-map type inspect dns preset_dns_map
 parameters
  message-length maximum client auto
  message-length maximum 512
policy-map global_policy
 class inspection_default
  inspect dns preset_dns_map
  inspect ftp
  inspect h323 h225
  inspect h323 ras
  inspect rsh
  inspect rtsp
  inspect sqlnet
  inspect skinny
  inspect sunrpc
  inspect xdmcp
  inspect sip
  inspect netbios
  inspect tftp
  inspect icmp
  inspect ipsec-pass-thru
  inspect ip-options
  inspect pptp
 class class-default
  set connection decrement-ttl
!
service-policy global_policy global
