Yes, I have read the FAQ.  I'm not a noob.. I never ask in the ML when I can 
have answers in FAQ... :P  But now, I have tried all, without results.

I can see the traffic from users (UDP traffic), but the remote window on 
gnomemeeting is alway grey. In other words, no image.

So, yes I have a communication with them.  They can see me, but I cannot see 
them.

Exaclty.

But, when an UDP packet reach the non-existent port (no opened for example) 
the machine will return a ICMP error message.

That never happen in this case, I have received all ports, they are all 
forwarded in range 5000-5003 and between 30000-30010.  Also, on port 1720 if 
they call me.

Yes, they are configured... I can send to you my tcpdump files, screenshot 
of my configurations from gnomemeeting, and others userful informations you 
will need, because I know they are all OK :-/  I have checked theses 
configurations many times...

Finally, I my original post, I told you when I connect with gnomemeeting 
user, it's work pefectly, but not with netmeeting users.

Thanks!
