You might need a stateful-inspection engine... Or a custom written proxy to
take care of all this ports. 

I know there are some other vendors supporting net-meeting proxies..
 
Your last resort would be pt up your net meeting server on DMZ with a pretty
much hardened box !!!! Configure trust relations accordingly

Subject: NetScreen XP and NetMeeting


Greetings,

As the subject goes, i need to get net meeting to work via NetScreen. I
found a KB
article(http://support.microsoft.com/default.aspx?scid=kb;en-us;158623) but
it seems to show, i had to open a whole range of ports. I am skeptical about
that!

e.g..
Pass through primary TCP connections on ports 522, 389, 1503, 1720 and 1731.
Pass through secondary UDP connections on dynamically assigned ports
(1024-65535).

the above shows a whole range of ports that i have to open. Is there a work
around.

Kind Regards
Gill
