Hi,
Are you trying to ping devices that are routed through your firewall?
By default if you don't have access-lists applied to your inside interface then you should be able to ping devices on lower security levels.
If you are trying to ping from an outside host to an inside host then you need an access-list
"access-list outside_in permit icmp any any"
followed by
"access-group outside_in interface outside"
If you are trying to ping your outside interface from an outside host then you need
"icmp permit any outside".
By default you can only ping an interface on a PIX if your host resides on that interface or on a connected subnet.
i.e. you can ping the outside interface from an outside host, but you can't ping the inside interface from an outside host.
