Charles,
Yes i now only see the "external" host ip in the DMQ packets (except for the callid header):

The value of the server address parameter is what appears in the from header - so if you want replies to go to your advertised/public address then this is what the server address should be set to.
Do the messages now contain the correct IP since updating the server address?
Cheers,
Charles

But after this to response from 10.20.8.88 back to 10.20.8.89 with the usrloc data. If i replace the primary node that should send the usrloc info with the original kamailio server that is not running in docker i see a KDMQ usrloc@... back to the server that is starting with all the usrloc data in the body.
Let me know if you need more details or debug logs.
Thanks,

Julien,
I have the following config:

I will collect some traces as well of the sync request as
requested by
Charles.

Can you share the settings you are using :
modparam("dmq", "server_address", "?") modparam("dmq", "notification_address", "?")

Hi all,
Is there any other way to filter DMQ peers? I now have a issue
with
dmq_usrloc when running in a docker container. When the node
comes
online the peer is sending the KDMQ usrloc packet (with the registered contacts) to the internal container ip and not the actual
external
ip. Both ip's show up as DMQ peers, after a few keepalive failures
the
dmq peer with the internal container ip becomes inactive and no
updates
are sent to that peer. But the usrloc sync seems to happen before
the
peer is inactive.
I tried to strip the peers with the internal container ip's,
this
works for the requests, but i'm not able to fix this for the
responses.
Thanks,

Hi all,
I'm trying to run a kamailio DMQ node inside a docker
container.
All
works fine but i have one issue with DMQ. Since the kamailio
process
inside the container is behind a nat i have set the advertise
address
to the external ip, this works fine for the via headers but DMQ
keeps
sending the internal interface in the KDMQ notification_peer
messages.
The external ip is in there as well. Example:
SIP/2.0 200 OK Via: SIP/2.0/UDP

ip sip:172.17.0.2:5060;status=disabled <-- entry for container
internal
ip
I tried to strip this entry using the replace_body_atonce in
the
tm:local-request route. This works fine for the KDMQ request,
but
when
i try to remove the same line from 200OK responses that are
send
out
as a response to incomming KDMQ messages this seems to fail. I
use
the
following code:
# Working code (for outgoing KDMQ requests): event_route [tm:local-request] { if(is_method("KDMQ") && $rU == "notification_peer") replace_body_atonce("sip:172.17.0.*:5060;status=.*", ""); }
# Failing code (for 200OK responses): reply_route { xlog("L_ALERT", "REPLY: Sending out reply, tU is $tU rs is
$rs\n");
if ($rs == "200" && $tU == "notification_peer") { replace_body_atonce("sip:172.17.0.*:5060;status=.*", ""); } }
I'm running kamailio 5.1.4. Is there a way to strip a line from
the
body of a local generated 200OK response? Or is there a way to
avoid
that DMQ inserts the internal container ip in the first place.
Thanks,
Jan Hazenberg
