This is a fairly simple question and i'm sure there is a fairly simple answer but for whatever reason I can't seem to get ICMP blocked properly on my external interface of my ASA.  I obviously don't want my external interface to be pingable but no matter what i configure in the ACL I am still able to ping the outside IP from outside of our network.
 
external ip is xxx.xxx.xxx.178.
 
What is the easiest, best practice way to accomplish this?

ICMP to and from the ASA itself is not controlled via the interface access-lists.

Use the following:

conf t
icmp deny any outside
0

our outside interface is actually named Outside_INF

so would the command be

conf t
icmp deny any Outside_INF?
