can inside clients ping the outside interface? What is the sysmon error ?

In the Pix firewall (ASA is built on the Pix Code), you are unable to ping one of the firewalls interface if its going through the firewall.
i.e. If you were on the inside network and pinged the inside interface, that would work because its not going through the firewall. If however you were on the inside network and pinged the outside ip address, then it would fail.
