I am fighting for days with a Jitsi instance on a virtual machine.
I just found that the server doesn't know it's own IP (don't really understand how it is virtualized). In the logs, I think the videbridge is binding to it's local IP that doesn't correspond to nothing real. I can see a lot of lines like theese ones :
JVB 2016-03-14 16:11:24.948 INFO:  org.ice4j.ice.Agent.createComponent() 10.0.0.2:4443/tcp (host)
JVB 2016-03-14 16:11:24.948 INFO:  org.ice4j.ice.Agent.createComponent() 10.0.0.2:10000/udp (host)
10.0.0.2 is the IP the machine sees. Maybe it's behind a vlan, I don't really know. I can confirm it with an "ip addr", for example. But it's real IP starts with 51.
Is there a way to inform the videobridge (and jicofo if relevant) of it's real IP ?
