Hi Damien,

We run an ipfilter based firewall which hides the LAN behind one
external IP addr with NAT. I've opened for my two laptops all
outgoing ports TCP and UDP > 1024 and I have no other firewall on
the laptops active. For incoming IP there are no special NAT redirect
rules, ie. only an outgoing UDP or TCP let come in a pkg for the
same connection.

I spend a lot of time testing both installations of Ekiga 2.0.2 in
the two laptops.... Both are configured the same way (NAT Traversal
Method: STUN, server: stun.ekiga.net, and for each of them I've
registered a separate login in 'ekiga.net').

The results are as following.

1. On both systems the registering to the server 'ekiga.net' is not
   very stable, sometimes it registers on first shoot; sometimes you
   can try it for half an hour in the tab of the accounts to get it
   registered; is there some load problem?

2. Calling up <500 ekiga net> gives a lot of times 'abnormal call
   termination' and in tcpdump you see some CANCEL:

   sometimes the call to <500 ekiga net> is successful;

3. when it is successful to <500 ekiga net> (the echo-room) I was able
   with the FreeBSD 6.1-RELEASE client to hear the greeting message about
   the echo-test and in this case traffic goes really in both
   directions:

4. with the FreeBSD 6.0-RELEASE client in a successfull call to
   <500 ekiga net> at the beginning I only see outbound traffic after
   the SIP exchange; und it does not play the greeting message:

5. with the FreeBSD 6.0-RELEASE client must be something completely
   broken, I think; on launching it with -d3 it says 6 times at the
   beginning:

   (ekiga:13943): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT
(object)' failed

   maybe the cause for the problem of the Subject:?

Thx
