Users outside of the Firms - VPN can't prodcast videos or audio, but can chat

Hello,

do to some bad hiccups from Ms Teams we wanted a backup solution. I quickly set up an ubuntu sever an installed jitsi-meet on it. The lets encrypt certs works …
But if users outside of the network which not uses an VPN, can’t broadcast video or audio in the jitsi rooms. We can see the external users and they can chat with us but that’s it.
The ports a correct forwarded - udp 1000 - did i miss something ?

best regards

udp 10000

me interesa. yo creo que lo solucione, pero fue cambiando otro puerto como el 10001
