<DIV class=gmail_quote>Hi Andrew,</DIV>
<DIV class=gmail_quote> </DIV>
<DIV class=gmail_quote>Sorry for not explaining correctly.</DIV>
<DIV class=gmail_quote>The server doesn't have a public IP, it is the public mapping that is configured on the NAT.</DIV>
<DIV class=gmail_quote> </DIV>
<DIV class=gmail_quote>Both the 200OK and the ACK are captured on the PC, where the clients are. </DIV>
<DIV class=gmail_quote> </DIV>
<DIV class=gmail_quote>If I use record_route(), then the "200OK" sent from the client is sent to the internal address (10.133.305.200).</DIV>
<DIV class=gmail_quote> </DIV>
<DIV class=gmail_quote>If I use record_route_preset("<A href="http://145.18.29.67/" target=_blank rel=nofollow><FONT color=#0000ff>145.18.29.67</FONT></A>") instead, then the 200 OK sent from the client is proxied through the server to the other client. On the other hand, the responding ACK has route=145.18.29.67 so the server actually sends it to it self. I've used Ethereal on the server to confirm this.</DIV>
<DIV class=gmail_quote> </DIV>
<DIV class=gmail_quote>Is there a solution to this, and can the solution also include calls from the internal network?</DIV>
<DIV class=gmail_quote> </DIV>
<DIV class=gmail_quote>Regards,</DIV>

<DIV class=gmail_quote><BR>Hi Andrijana,<BR><BR>Do you mean the server does not have a public IP and <A href="http://145.18.29.67/" target=_blank rel=nofollow>145.18.29.67</A> is just a public IP mapping configured on the NAT/router? That explains why<BR>advertised_address setting did not have effect on the Record-Route (it<BR>must be an address OpenSIPS listens on). Or the server has two real network interfaces (public and private) and OpenSIPS is listening on both?<BR><BR>It's quite important to know whether 200 OK sent by Zoiper and ACK sent by X-Lite are shown as caught on the server's outgoing interface or on the your PC. I think that both have been captured on the PC since I'm not seeing the server's address anywhere in the Via headers. But that leads to a difficult question.<BR><BR>It's indeed strange that 200 OK doesn't go through the proxy server. ACKs for 2xx responses use the Route values learned from the Record-Route of the 2xx responses, so
X-Lite must send ACK through the proxy. You say currently it sends it directly to the peer, right? The next step depends on the configuration, e.g. if your OpenSIPS is listening on private and public interfaces you should set the enable_double_rr param of the rr module to 1.<BR><BR>Andrijana Popovska wrote:<BR></DIV>
