Hi

When I run this, I get this:

vaio:/home/ben# gconftool-2 
-g /apps/gnomemeeting/protocols/h323/ports/tcp_port_range
30000:30010
vaio:/home/ben#

When I log into my router, these ports are open for me

	1		NETMEETING		1720	1720	192.168.0.4
	2		NETMEETING		1503	1503	192.168.0.4
	3		H.245 for Netmee	30000	30010	192.168.0.4
	4		Netmeeting Trying	5000	5016	192.168.0.4

Now, I am puzzled again. The ports are all open. On the NM side, there is DMZ> 
I can even telnet to port 1720. What might be wrong?

When I send a call to a NM on my local network, the video goes through, so I 
think it should work fine overseas as well. The two NMs are identical, 
Japanese Windows XP. One works, that is on the LAN, and one rejects, which is 
in Japan.
