<div>Indeed this issue does not manifest at all. I'm awfully
sorry for the false alarm, and on release day no less!</div>

</div>
<div>The problem was there was a lingering DNAT rule in
iptables, which would translate port 5066 to port 5060. The
deployment script injected this as it was carried over from
our legacy platform.</div>
<div><br>
</div>
<div>Of course, I kept banging my head against the wall here
because sngrep wouldn't show the DNAT's effect as it captures
traffic from the NIC directly: it would show a REGISTER
arriving on 5066, but the dport was masqueraded before being
handed over to kamailio. Similarly for the outgoing INVITE.</div>

<div>Hello all,<br>
<br>
</div>
I have the following issue in my
configuration, tested with 5.2.0-rc1 so far:<br>
<br>
</div>
At some point, I set the $fs pseudovariable to
force a request to be relayed through a
specific socket. Although this is honoured by
kamailio (i.e. the request does indeed leave
the kamailio host from the respective socket),
the port number is not added to the Via and RR
headers. As a result, all replies to the
request, as well as all subsequent requests
from the other SIP UA are relayed to the
default port, 5060. Here's an example:</div>
<div><br>
</div>
<div>SIP UAC to kamailio:</div>
<div style="margin-left:40px">INVITE <a
href="http://192.168.1.1:5060"
target="_blank" moz-do-not-send="true">192.168.1.1:5060</a>
---> <a href="http://192.168.1.254:5060"
target="_blank" moz-do-not-send="true">192.168.1.254:5060</a></div>
<div>Kamailio to UAS ($fs is set):</div>
<div style="margin-left:40px">INVITE <a
href="http://2.2.2.2:5066" target="_blank"
moz-do-not-send="true">2.2.2.2:5066</a>
---> <a href="http://3.3.3.3:5060"
target="_blank" moz-do-not-send="true">3.3.3.3:5060</a></div>
<div style="margin-left:40px">Topmost Via in
request relayed by kamailio is:</div>
<div style="margin-left:80px">SIP/2.0/UDP
2.2.2.2;branch=aaaaaaaaaaaaaa <wbr> <-
port 5066 is not added<br>
</div>
<div style="margin-left:40px">Topmost RR in
request relayed by kamailio is:</div>
<div style="margin-left:80px"><a
class="gmail-m_5571352520475869339moz-txt-link-rfc2396E"
moz-do-not-send="true"><sip:2.2.2.2;r2=on;lr;did=<wbr>bbbbbbb;nat=yes></a>
<- port 5066 is not added</div>
RESULT: Reply from UAS is sent to <a
href="http://2.2.2.2:5060" target="_blank"
moz-do-not-send="true">2.2.2.2:5060</a><br>
<div>
<div>
<div><br>
</div>
Is this behaviour valid? Am I missing
anything? Kamailio is configured to listen
on both sockets on IP 2.2.2.2, namely: a)
udp:<a href="http://2.2.2.2:5060"
target="_blank" moz-do-not-send="true">2.2.2.2:5060</a>
and b) <a href="http://2.2.2.2:5066"
target="_blank" moz-do-not-send="true">2.2.2.2:5066</a>.
Thanks.</div>
