Hello,<br>
<br>
First of all, I'm spanish and my english isn't good, so please excuse my mistakes.<br>
I've been working with openser for a year. Now I'm modifying my SIP service in order to allow clients in NAT scenarios.<br>
I've read about symmetric / full cone / ... and other NAT scenarios.
I've read about mediaproxy / rtpproxy and nathelper modules.<br>
I've got a openser.cfg working properly without NAT clients. And I've modified it (see attach).<br>
<br>
Client X-Lite:<br>
IP: <a href="http://192.168.1.2">192.168.1.2</a> (public address <a href="http://81.39.220.5">81.39.220.5</a>)<br>
Listen SIP port: 5060<br>
Listen RTP port: 8000<br>
<br>
Server: Openser 1.0 with Media Proxy<br>
IP: <a href="http://147.83.197.39">147.83.197.39</a><br>
Config in opernser.cfg<br>
<br>
If i try to register with a UAC (X-Lite or K-Phone) with symmetric NAT
scenario. Opernser server doesn't answer the client to 5060 port, as i
need.<br>
X-Lite Diagnostic LOG is client_messages.txt<br>
Client timed out without receiving any server messages.<br>
<br>
This is a tcpdump on clients side:<br>

On the server this is the tcpdump:<br>

<br>
What's wrong?<br>
<br>
It's necessary to use a STUN server?<br>
Why can't register?<br>
Why openser doesn't reply to 5060 port? My client it's only reachable in this.<br>
Can anyone help me?<br>
Anyone have a OpenSer config working?<br>
<br>
Thanks in advance<br>
