Hello<div><br></div><div>I got the following setup: Phones -&gt; FreeSwitch -&gt; NAT -&gt; Internet -&gt; Gateway</div><div><br></div><div>And I&#39;m struggling to get NAT working properly. I&#39;m running freeswitch with the &quot;-nonat&quot; option and have tried different ext-rtp-ip/ext-sip-ip combinations in external/internal profiles.</div>
<div>The From header seems to be correct while contact header and SDP uses local ip? Please help me configure everything correctly.</div><div><br></div><div>Currently I have this setup:</div><div><br></div><div><div>API CALL [sofia(status profile external)] output:</div>
