Making P2P Video Chat with FMS

Hi, I'm trying to make a P2P video chat application with Flash Builder 4.5 and Flash Media Server 4.5.

First, I've tried a simple sample application using Cirrus(Stratus). It worked very well!

NetConnection -> NetGroup -> 2 NetStreams -> netstream play and publish -> last, netgroup post

The sample was all OK.

But now, I've changed the server url to my flash media development server.

rtmfp://p2p.rtmfp.net/XXXXXXXXXXXXXX -> rtmfp://my-fms/application

Here is my application trace log about NetStatusEvent:

[object NetConnection] NetConnection.Connect.Success

[object NetConnection] NetGroup.Connect.Success

[object NetStream] NetStream.Play.Reset

[object NetStream] NetStream.Play.Start

[object NetStream] NetStream.Publish.Start

[object NetConnection] NetStream.Connect.Success

[object NetConnection] NetStream.Connect.Success

I couldn't get events about NetGroup and NetStream any more!!!!

When using Stratus, It worked well...

I am not familiar with FMS.. did I skip something in FMS setting?
