Mediasoup WebRTC IP address

[Richard Phillips]

Latest 2.5.8 installed and working, but have a problem when re-configuring machine with different IP address as this breaks webrtc. 

I have a script which did this successfully in 2.4 - but I now (with 2.5) appear to be missing something - likely with mediasoup. 

I update the following files with the correct IP address, and also correct the dummy NIC

/opt/freeswitch/etc/freeswitch/vars.xml

/opt/freeswitch/etc/freeswitch/sip_profiles/external.xml

/usr/local/bigbluebutton/bbb-webrtc-sfu/config/default.yml

/etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini

Restart BBB and meetings work fine - though sharing video fails with ICE errors. 

On examination (webrtc:about) I can see that mediasoup is reporting the WRONG ip address (ie. the old one, before scripts re-allocated this)

So my question is quite simple - where else do I need to change the IP address in order for medasoup WebRTC negotiation to report the correct external IP address of the bbb server? 

Thanks for any nudges!  

Regards

Did you change the settings in the Coburn server as well?

Coturn...damn spell check.

Many thanks Andrew - I think I figured out this particular problem. 

The problem was that (I think new in 2.5) bbb sets up a systemd service to set up the dummy NIC for freeswitch: /usr/lib/systemd/system/dummy-nic.service  - and this still had the old IP address which was set as the dummy-nic IP every time the machine booted.  

I also had the wrong old IP in one of the override files.  

For anyone who passes this way: the simplest way of updating IP address if that changes on your machine appears to be re-running install.sh - but if you are doing something where this is not practicable, checking all the overrride files as well as the dummy-nic would be a good place to start!  Check ip addr and check that it does not show two different external ip addresses...

I now have everything working chrome but sound webrtc is failing on FF but will raise that in yet another email if I can't figure it out!

Thanks again

Richard
