Dave,
Your first scenario would have worked if you would have disable icmp
under properties.  FW-1 by default will allow ping unless specifically
denied in a rule or better, just disabling icmp under properties as I
stated above, is the best way to go.

Rafeeq,
FYI: Raptor is an application gateway firewall which stops icmp.

Edit objects.c and change the <display in menu> tag from T to F.  This
will not show the object in the window and allow you to add more
objects.  Obviously, you only want to do this for objects you dont need
often.  Its a mikey-mouse solutions, but until sun changes their XVIEW
libraries, you stuck with this solution.
