Hi

Do you still remember still my problem? I in the meantime located
another NM box, wich now is in Hungary (same as I am) and has a
Hungarian windows, that I do understand. What happenes is, that it has a
Belkin router in front, and that belkin has a built in feature for
Netmeeting, so I can just click, and all ports are open for the NM.
Great, I am able to make calls now from the GM to the NM box with no
problem. So we established, that the problem was on the Japanese NM'
side, sone weird routing issue, maybe ISP related. So now, I have
ability to call from GM to NM and NM to GM. Call goes through, all
happy, except no video again. I was curious enough to travel to the
location where this NM resides, and hooked my GM to the same LAN, and
voila, video travels like a charm. No new ports opened on the SP2
firewall, and nothing changed, just being on the same lan. When I go
back to my location, hook the GM to my router, it wont send video again.

Somebody must be able to tell me how can I troubleshoot this problem?
Tcpdump on GM side, but what on NM side? And how to use Tcpdump
efficiently? Or what else to use? Really flustating problem.

Thanks again and sorry for the long-lasting thread. I hope I am close to
solution.

THanks
