<p>I was getting ready to implement this but I'm questioning
something. </p>
<p>The PBX itself is not behind a NAT. Why would I set the
ext-sip-ip and ext-rtp-ip to use autonat? <br>
</p>
<p>Presently thety are set to the below where private_rtp_ip is the
RFC address space IP of the internal interface of the PBX.<br>
</p>
<p><param name="ext-rtp-ip" value="$${private_rtp_ip}"/><br>
<param name="ext-sip-ip" value="$${private_rtp_ip}"/><br>
</p>
<p>Also, in the profile I have <param name="local-network-acl"
value="localnet.auto"/> already. <br>
</p>
<p>thoughts?<br>

<p>Let me try this.</p>
<p>I have a public network interface connected to the
external profile with ip <a href="http://1.1.1.1/24"
target="_blank" moz-do-not-send="true">1.1.1.1/24</a>
(e.g. of course) I have a private subnet attached to the
internal profile on <a href="http://192.168.0.2/24"
target="_blank" moz-do-not-send="true">192.168.0.2/24</a>.
I've got polycoms registering to 192.168.0.2 using TLS
that show up as 192.168.0.1 given they are NAT'd behind
this firewall. It seems that if the devices try to
register to .2 via an ip on the same subnet that NAT
detection is not happy. When the clients come from
something totally different it works. Any way to force
this to work?<br>

<p>Not sure I 100% follow. The clients are on the
same /24 as the "internal" profile interface is
on. The only thing is they are behind a NAT. <br>
</p>
<p>What led me to this was I had a previous
configuration whereby the internal and external
profiles were on the same interface IP. When the
clients connected to the internal profile via an
totally different public IP, but also behind a NAT
it worked (registrations showed fs_nat and a
fs_path properly). However, for this
configuration when I put the clients on a NAT that
was on the same subnet as the internal and
external shared IP it wouldn't work. I thought
maybe this was an issue with the profiles sharing
the same IP. Thus I split it to the configuration
I documented below. It makes me think that the
NAT issue is related to the fact that the profile
IP is on the same subnet as the NAT. <br>

<br>
I'm running FreeSWITCH Version
1.10.3-release~64bit (-release 64bit) on<br>
a FreeBSD 12.1 box.<br>
<br>
The issue I'm having is related to NAT, I'm
sure no one has ever seen a<br>
post on this topic....<br>
<br>
My configuration is a box that is multi homed
with an Internet facing<br>
interface and a private IP LAN interface. The
clients (Polycoms) are on<br>
the private LAN interface but behind a NAT
(pfsense) on this subnet. If<br>
I have the clients route directly to the FS
box's private LAN without<br>
NAT I can make this work but as soon as I NAT
them (which I need to for<br>
other reasons) I don't see the registrations
show up with fs_path or the<br>
other variables like I might expect.<br>
<br>
I've fiddled with the apply-nat-acl variable
to no avail. <br>
<br>
Thoughts?<br>
<br>
Thanks<br>
<br>
Jim<br>
