NetMeeting uses the following Internet Protocol (IP) ports:

Port Purpose
-------------------------------------
389 Internet Locator Server [Transmission Control Protocol (TCP)]
522 User Location Server (TCP)
1503 T.120 (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)]

To establish outbound NetMeeting connections through a firewall, the firewall
must be configured to do the following:

- Pass through primary TCP connections on ports 522, 389, 1503, 1720 and 1731.

- Pass through secondary UDP connections on dynamically assigned ports
(1024-65535).
