I am hosting a jitsi-instance on my laptop (Ubuntu 18.04) in my local network behind my router (DSL connection 100Mbit/s down, 40Mbit/s up). I know that this might not be the ideal setup but since I just do it to have informal conversations with a couple of colleagues, it is okay.
I spent hours of setting up the NAT but now it works like a charm. BUT… after every reboot of Ubuntu I have to restart the service jitsi-videobridge2 (sudo /etc/init.d/jitsi-videobridge2 restart).
The service starts after reboot (= it is shown as active/running) and I can access the start-page of Jitsi using my subdomain - but no video meetings with people from outside my network (= internet) are possible. After restarting the service it starts working again.
Do you have any ideas? Thanks in advance!
