	Yes, that is the symptom that I have heard of.  The reason he can
	not see the other party, is because his host is trying to send to
	a private address...that is non routeable.  If you talk to him,
	you can verify that netmeeting on his machine is trying to connect
	to the private address of the machine that is on your private
	network.

	The firewall is not the problem...its nat.

	Yep.  You may be able to run some sort of H323 gateway proxy that
	would eliminate the problem.  Check out www.openh323.org [I
	think].
