Ports used by Netmeeting and their Purpose
Solution
In order to use MS Netmeeting behind a firewall, you'll need to configure the appropriate ports:
1) TCP (bidirectional) over 389, 522, 1503, 1720 and 1731 (purposes see below)
2) UDP (dynamically assigned): 1024 - 65535 (see below)
Port Purpose
-------------------------------------
389 Internet Locator Server (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 (UDP)
- when TCP connections on specific ports is enabled, but no secondary UDP connections on dynamically assigned ports, audio features cannot be used
