[Freeswitch-users] Calls between extensions with no audio on NAT

I'm having a problem with a NAT scenario, I have some pcs (
and using verto behind a NAT calling to a LAN FS

I added a gateway and the callout is working good enough, but the calls
between extensions I am not getting audio, I just get the "No audio stun
for a long time!".

I set in many ways the following:

 <param name="ext-rtp-ip" value=""/>

 <param name="ext-sip-ip" value="auto"/>

I tried auto, auto-nat, $${external_rtp_ip} and $${external_sip_ip}
respectively, and that one I just added with no luck.

What can be the problem with this?
