Hello all,<br>
I&#39;m having a strange NAT problem.  My Freeswitch server has a public<br>
ip and the endpoints which are Polycom IP 650s are all behind NAT with<br>
mainly Netgear SRX 5308 routers at multiple locations.  The server is<br>
on a public class C network and one of the locations has its router on<br>
the same class C.  I.e x.x.x.7/24-router, x.x.x.240/24-server.  I&#39;m<br>
only experiencing this with 2 of about 30 extensions.  The first<br>
endpoint to register from this location gets detected as NAT but the<br>
others with the ports remapped do not. This maybe explains it better:<br>

The port and IP are detected correctly but the contact is a private<br>
IP.  Any clue as to why the two extension 1101 and 1102 are any<br>
different?<br>
<br>
Thanks,<br>
