Blocking All Incoming ICMP Traffic With Cisco ASA 5510
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?
