Stateful Packet Inspection

["Paul Kurczaba" <paul () myipis com>]

I have set up a free online security scanning site located at http://scan.myipis.com. One of the ports that it probes 
is the clients source port. Am I correct in saying, that if the status of the source port is "stealth", the remote 
firewall uses Stateful Packet Inspection; and if the status is "closed", the firewall does not use Stateful Packet 
Inspection?
