<p class="MsoNormal"><span style="color:#1F497D">I’ve done some more troubleshooting on this and it doesn’t appear to have anything to do with the NAT. The issue seems to be related to one host sending calls to Opensips. From all other hosts it works fine,
but this one host doesn’t work at all. I’ve double checked the ip address, port, etc. I”ve also tried removing the address from the table and adding it back, still nothing. Very strange.<o:p></o:p></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This server is behind a firewall doing NAT and I’ve changed all references in the opensips.cfg to the new external address.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Opensipsctl address dump shows the address table and the server that’s sending the calls from properly.

<p class="MsoNormal">I’m not really sure where to look next, I’m pretty green when it comes to opensips. I only have to tinker with it when I change something like this. Any assistance would be greatly appreciated.<o:p></o:p></p>
