Don't remember where I found this, part of a downloaded DOC ant Microsoft's
site if I remember correctly...
Hope it helps... I think it pertains to 3 (that's what I use) but there is
no way for me to tell from the excerpt I saved.

Proxy server configuration details
Sometimes a proxy server limits the use of certain ports because of security
concerns. NetMeeting cannot communicate fully if it is blocked from using
the following ports:
� 389 LDAP (TCP)
� 522 User Location Server [Transmission Control Protocol (TCP)]
� 1503 T.120 protocol (TCP)
� 1720 H.323 call setup (TCP)
� 1731 Audio call control (TCP)
� Dynamic H.323 call control (TCP)
� Dynamic H.323 streaming [Realtime Transport Protocol (RTP) over User
Datagram Protocol (UDP)]
In addition, to establish outbound NetMeeting connections through a proxy
server, the proxy server must be configured to do the following:
� Pass through primary TCP connections on ports 389, 522, 1503, 1720 and
1731.
� Pass through secondary UDP connections on dynamically assigned ports
(1024-65535).
Notes
� Some proxy servers can pass through TCP connections on specific ports, but
cannot pass through secondary UDP connections on dynamically assigned ports.
� Some proxy servers can pass through TCP connections on specific ports and
secondary UDP connections on dynamically assigned ports, but cannot
virtualize an arbitrary number of IP addresses, or cannot do so dynamically.
� With these proxy servers, you can establish NetMeeting connections from
computers inside the firewall to computers outside the firewall and use the
audio features of NetMeeting, but you cannot establish connections from
computers outside the firewall to computers inside the firewall.
If both you and the user to whom you are trying to connect are operating
behind proxy servers, you may have better results if you use a Multipoint
Conference Unit (MCU). Consult your IS administrator for information on how
to connect using an MCU.
