No video or sound

I’m trying to run this at home. I have dynamic dns updating set up and ports 80, 443, 4443 and 10,000 forwarded to the machine running jitsi meet, etc. The machine has four cores, 16gb RAM running Debian Stretch. When testing it, chatting works but no video or sound. Even trying two local machines, it is not working.

Am I missing something in my setup or missing a port that needs to be forwarded?

The following extra lines need to be added to the file /etc/jitsi/videobridge/ when you are behind a NAT

Personally I have bough an extra network card and replaced my router with the debian machine running jitsi and configured it as the router. By doing so i have removed all bottlenecks in my network.

Many thanks! Worked like a charm!
