[GnomeMeeting-list] Configuration for calls with Netmeeting Users

[TD <nospam neuf fr>]

Dear gnomemeeting-list reader,

I am looking for some help or advice. I am trying to establish connection with 
correspondant running Netmeeting under windows XP (recognized by GM as 
Microsoft(R) Netmeeting (R) 3.0 181/21324).

My problems are:

*  For the calls I make to netmeeting, my correspondant don't get 
notification.

*  For incoming calls, I can see the windows which warns that somebody is 
trying to call me, but when I authorized the connection, nothing happen. 


I am not a expert in firewall and videoconf configuration, and I did not found 
or understood documentation relative to my case.

Test cases with both firewall deactivated did not allow us to connect either.


My PC is a standalone workstation running with Mandrake 2006 and GM 1.2.2.
My firewall is configured with shorewall with the following parameters 
in /etc/shorewall/rules:
-----------------------------------------------------------
..
# Listening Port: TCP port 1720,  If you don't forward that port, then other 
users won't be able to call you.
ACCEPT          net     fw      tcp     1720
# H.245 Port Range: TCP port range [30000-30010],
ACCEPT          fw      net     tcp     30000:30010
ACCEPT          net     fw      tcp     30000:30010
# RTP Port Range: UDP port range [5000-5016],
# This port range is used for the RTP and RTCP channels for audio and video 
transmission/reception.
ACCEPT          fw      net     tcp     5000:5016
ACCEPT          net     fw      tcp     5000:5016
...

Here are some debug data output:
