Jvb client connection over colibri websocket

Unfortunately I cannot find any documentation on howto instruct clients of using websocket for jvb.
The jvb does not listen on 10000 UDP, and I also am unaware why, noting in logs, so I tried to connect my clients over colibri websocket.
The forum is full with questions on websocket proxying and mix-ups with xmpp websocket, found nothing useful here.

The question is how should I configure the system to force client try to connect to the jvb over colibri websocket?

I use jvb, jicofo, jitsi-meet from latest git, also tried latest stable jvb, no luck with both websocket and WebRTC. No error in any log, but jvb does not listen on ice ports.

If JMS and JVB are on the same host, there is no need to do anything. It works with the default config. JVB starts to listen UDP/10000 after the first room created

so you may conclude, having seen the log, the jvb instance is quite well configured?
when I start the conference first user is unable to connect, and not because ice listener is down, correct?


As you say, JVB starts to listen on udp:10000 once the first room is created. I have a VM with 3 interfaces. I need JVB to only listen on one interface. It must not bind to the other two interfaces. How can i configure the interface to use, please ?

Thanks in advance.
