What ports to use for netmeeting?

[IsOs]

Given 3 computers, computer A has one nic connected to the hub. Computer B has 2 NICs, 1 connected to the hub, the other one connected to computer C. Computer B acts as a relay computer where ports are forwarded between A & C. What TCP or UDP ports should I open & forward for Netmeeting to work between computer A & C. Computer A is Windows 2000 Pro, Computer B is Windows 98SE and Computer C is Windows Millenium.

Any help is highly appreciated.

Check Microsoft's Knowledge Base for the specifics. I believe there are at least three ranges of ports you have to work with. I believe for security they are still using a variable port to the video stream and another one of the audio.

Thanks for the suggestions. That's my last resort. I was hoping someone here have similar experience and know the answer.
