Yes it is actually terminating and opening a new connection.<br>
<br>
I don't need HAProxy for anything at the moment, I was mentioning
it for its support of the proxy protocol which enables
applications to get source address information behind TCP load
balancers.<br>
<br>
I'm not so much worried about the speed of kamailio - I'm
confident it's quite fast. But for every piece of infrastructure I
need to stand up, there's another opportunity for failure. Being
able to use an ELB at the edge lets me place some of that hard
work on Amazon, who has already thought of things like DNS load
balancing, multi zone failover, etc.<br>
<br>
I think it'd be great if Kamailio could support something like
proxy protocol to allow this scenario to work (it's just a single
line sent right after a TCP connection is opened)<br>

I haven't found any need myself for using haproxy, and as we work as
a community adding features as one needs them, if someone will
submit a patch for support of haproxy, will be considered, of
course. Personally I have no haproxy around, so not something that I
quickly look further at such feature.<br>
<br>
Cheers,<br>

<p>Hello,</p>
<p>is the tcp load balancer changing the source address,
like accepting the connection from the phone and then
opening one to kamailio?</p>
<p>Do you need haproxy because of other reasons or only for
sip?</p>
<p>A kamailio load balancer (sip aware) is also quite fast.<br>

<div dir="ltr">Hey all,
<div><br>
</div>
<div>I'm looking to put Kamailio behind a TCP load
balancer that is SIP-unaware. My application is
deployed in AWS and I'm tying to place Kamailio behind
an ELB.</div>
<div><br>
</div>
<div>For the most part, everything is fine. For my
specific implementation I'm disabling UDP as a
signaling transport and using only TLS. This enables
me to not have to worry about a SIP-aware LB at the
edge because replies to an incoming request will be
sent over the existing established TCP socket
(avoiding any crazy routing requirements).</div>
<div><br>
</div>
<div>However - this poses an issue with source
addresses. Does Kamailio support anything like the
proxy protocol (<a moz-do-not-send="true"

target="_blank">http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt</a>)
for getting TCP stream information from a load
balancer? Do I need to go back to exposing it directly
to the world so that I can get source addresses?</div>
<div><br>
</div>
<div>Thanks,</div>
