You can install the Kurento Media server with using our Kurento installation guide. To make Kurento work perfectly behind NATs, you need a Turn server. Coturn is an opensource turn server. We can easily setup Coturn on Ubuntu 16.04 (Xenial) with official Coturn repo.
First Make sure that you have opened up following ports in your firewall
3478 : UDP 49152–65535 : UDP
