[GnomeMeeting-list] Another Gnomemeeting-Netmeeting problem

[Dean Tsou <dttsou iinet net au>]

Hi All,

I've been trying to get my Gnomemeeting to work behind the firewalled 
gateway on my home network for ages! It is finally SORT OF working using 
the gnugk (openh323gk) . I am trying to call someone outside my home 
network who is using NetMeeting without a firewall/NAT. The result is 
that they can see me, but I can't see them (I have made sure that they 
are transmitting video).  I believe my problem lies in the port 
configurations on my gatekeeper and firewall. I have tcp ports 
30000-30010 open as well as 1720-1721 open... I don't have any udp ports 
open for it. Could that be the problem?

BTW, can someone explain to me what the use of tcp ports 30000-30010 and 
udp ports 5000-5003 are used for?? I am not clear on the H323 protocol 
and have done lots of searching on the web without much success. Have 
also read the FAQ but still don't know what ports are used for what. Any 
help would be appreciated.

Cheers,
Dean
