Hi All<br>
<br>
I&#39;m a new member and trying to use Openser as my VOIP &quot;router&quot;<br>
I plan to make following configuration:<br>
<br>
<br>
UA &lt;---&gt; Openser &lt;---&gt; Firewall/NAT &lt;--INTERNET--&gt; Firewall/NAT &lt;---&gt; UA<br>
a.a.a.a/24&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; x.x.x.x&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; y.y.y.y&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; b.b.b.b/24 &nbsp;&nbsp;&nbsp;  <br>
<br>
<br>
a.a.a.a and b.b.b.b is internal IP not internet route-able<br>
x.x.x.x and y.y.y.y is Firewall/NAT external IP number<br>
<br>
I know there is mediaproxy and RTPProxy to solve the UA b.b.b.b that
behind NAT but I don&#39;t know if my decision to put Openser behind NAT is
correct or not. <br>
How to archive the above diagram with Openser ?<br>If above Openser location is wrong, where should the Openser reside in the diagram? Install in Firewall/NAT or in INTERNET (dedicated server)<br>
<br>
Thank you for your help and sorry if my question is too newbie<br>
