This is true, but if the services run in the dmz, there is far less a
threat to the soft cneter network if they get hit <the DMZ services>. If
run on the FW and you seen not the vuln in the lists, are too busy to
patch if you saw it, or something else interfieres, you are more liely to
toast more then a singe services server on the outside.
