This is my current setup, which works:<br>SIP client &lt;-&gt; SIP server.<br><br>As I&#39;ve currently moved to another country I would like to be able to do the following setup:<br>SIP client &lt;-&gt; Kamailio SIP proxy &lt;-&gt; SIP server.<br>

<br>As the SIP server only accept packets from specific IP&#39;s.<br><br>Is it possible?<br><br>I&#39;ve managed to setup a simple Kamailio installation on my server, which does have a valid IP for the SIP server.<br>With the Kamailio installation I&#39;ve also enabled NAT with RTPProxy.<br>

<br>My problem is now, that the Kamailio installation doesn&#39;t work as a simple proxy, but actually takes registrations etc. and acts as a &quot;full-blown&quot; SIP server.<br><br>It should only take SIP messages and transfer them between clients and server.<br>

<br>Any ideas?<br>
