Hi,

I have a quick NAT related question.

Is there a way to disable NAT handling completely?

FreeSwitch always replies to the IP/Port were it received the message from and not to the host/port in Via....

recv 1166 bytes from udp/[172.17.0.1]:36835 at 10:20:56.652918:

Is there a way, to make FreeSwitch simply reply to the Host/Port in the Via-Header?

My Profile is rather simple and I tried it with setting the local network ACS and NDLB-force-rport:

    <profile name="local">
   <settings>
   <param name="local-network-acl" value="none"/>
<param name="NDLB-force-rport" value="disabled"/>    
   <param name="context" value="local"/>
        <param name="sip-ip" value="$${local_address}"/>
        <param name="ext-sip-ip" value="autonat:167.99.136.226"/>
        <param name="sip-port" value="5080"/>
        <param name="rtp-ip" value="$${local_address}"/>
        <param name="ext-rtp-ip" value="autonat:167.99.136.226"/>
        <param name="auth-calls" value="false"/>
      </settings>
    </profile>

Changing "NDLB-force-rport" to false did not have any impact.

Thanks,

Carsten
