Dear all,<br>I&#39;m testing my proxy and I&#39;m using mediaproxy for natted client.<br>Everything works fine, if there is a client behind nat calling a public user, mediaproxy works fine. This is true also if there is a public client calling a natted user.
<br><br>I have some problem when there are 2 client behind NAT. <br><br>1. I tryed to test the system with 1 client behind NAT and 1 client behind the SAME NAT (both of client under the same subnet:192.168.10.x).<br>&nbsp;&nbsp;&nbsp;&nbsp; In this case Mediaproxy doesn&#39;t work. RTP in direct between clients.
<br><br>2. I tryed to test the system with 1 client behind NAT and 1 client behind
the SAME NAT (with clients under different subnet:192.168.10.x and 192.168.0.x).<br>
&nbsp;&nbsp;&nbsp;&nbsp; In this case Mediaproxy doesn&#39;t work. RTP in direct between clients.<br clear="all"><br>This is Mediaproxy Debug in the last case:<br><br>**********************************************<br>

And xlogs DEBUG show me that openser enters in &quot;use_media_proxy&quot; routine) . 
<br><br>But when I sniff the packet on client side, I see SDP part with private IP !<br><br>Any suggestion?<br><br>Regards,<br>daniel<br><br>-- <br>Daniel Grotti<br>________________________<br>e-mail : <a href="mailto:d.grotti@gmail.com">
