<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have the following setup:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>UA1(1000@192.168.1.x) --> NAT box (@public IP) -->
OpenSIPs (@public IP) <-- UA2(1001@public IP)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Both UA1 and UA2 are registering fine. Call from UA1
(private IP) to UA2 (public IP) succeeded. However, call from UA2 to UA1 failed
with error 513.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Ngrep shows the below, I assume after proxy authentication
required by OpenSIPs, UA2 should return an INVITE with Proxy-Authorization
header? In this case, an ACK (in bold) was returned by UA2. Any
idea?<o:p></o:p></p>
