For a REGISTER you should use the fix_nated_register() function.<br>

<div>Here's another log, I'm doing 'fix_nated_register' in this
case at the REGISTER route and doing 'fix_nated_contact()' at
the very beginning of my script, just for the testing purpose.<br>

Are there any errors when the "fixing" is done? The

<div dir="ltr">Hi,
<div>I'm using OpenSIPS 3.2.4 and recently run into
following issue:</div>
<div><br>
</div>
<div>Imagine simplest proxy setup - OpenSIPS just
accepts new packet, for example INVITE, changes
destination using 'sethostport(....)' and then issues
't_relay()' to forward the packet. Let's ignore
replies and so on.</div>
<div><br>
</div>
<div>If I'm doing a 'fix_nated_contact()' before sending
this packet I'm expecting Contact: field to be
replaced with a source IP:port as per manual. And this
works if the Contact is in simple form like '<a href="http://sip:7777777@192.168.29.106:65033" target="_blank">sip:7777777@192.168.29.106:65033</a>'.</div>
<div><br>
</div>
<div>But if following Contact comes in OpenSIPS doesn't
change it leaving private IP in the contact:</div>
<div><br>
</div>
<div>'Contact: <a>sip:7777777@192.168.29.106:65033;rinstance=2f59b175103f1088</a>'<br>
</div>
<div><br>
</div>
<div>Can you please let me know why is that happening?
Thanks!<br>
</div>
<div><br>
</div>
<div>Best regards,</div>
<div>Yury.</div>
