<p>Hello Markus,</p>
<p>another idea: the dmq module supports multiple destinations, so you could enter a internal and public IP adress into a A record, and then let dmq connect to both. But the actual routing descision is (currently) done on a linux network layer level.<br>
</p>
<p>Cheers,</p>

Hello Henning,

</div>
<div class="">I was hoping that there would be a way with dmq, but anyway I’ll solve this on network level. Thanks for the hint.</div>

This is a bit an IP routing question, as Kamailio more or less just send the message out to the network stack.<br class="">

Another idea would be to enter a DNS record as dmq endpoint and then change it with a monitoring trigger event. Not 100% sure how dmq refresh this, will need some testing.<br class="">

Hello NG,<br class="">
<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
I have a question regarding the dmq / dmq_userloc module.<br class="">
<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
In my test setup have 2 Kamailio servers in 2 different data centers. <br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
The data centers are interconnected by a crosslink.<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
Each Kamailio server has configured an internal (private) and an external (public) IP address.<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
The internal IPs are routed to use the crosslink.<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
The external IPs are routed through the public internet by different ISPs.<br class="">
<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
The requirement is that the replication should primarily be routed via the crosslink, only if the crosslink is down it should be routed via public internet. <br class="">
<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
As I understand the „server_address“ parameter can have only one IP address. <br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
If I configure the public IPs on both sides and one ISP connection gets disconnected, packets will NOT be routed automatically via the crosslink. <br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
And the other way around, if I configure the private IPs on both sides and the crosslink gets disconnected, packets will NOT be routed automatically via public internet.<br class="">
<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
Is there any way to setup and use dmq for such a scenario ? <br class="">
<br class="">
</div>
<div dir="auto" style="direction: ltr; margin: 0px;
padding: 0px; font-family: sans-serif; font-size: 11pt;" class="">
Thanks and regards<br class="">
