If you want to ease the woes then just order a small vps and install jitsi on it.  I am trying to save some money so have it in a virtual machine.  Can connect but no audio, no video from the users.  If anyone has set up jitsi in a vm and using nginx as reverse proxy to jitsi server, please help out.  Maybe I need to change how the network from the host to the client is set up.  Documentation from jitsi isn't the greatest.
