On this page you will find how to install and configure a Kurento Media Server environment.

Requirements

Hardware

Minimum hardware requirements are:

• 2 cores - CPU
• 4GB di RAM
• 40GB di HDD

Software

Recommended operating system is Ubuntu Linux 18.04 LTS Server.

Network

On your firewall you will have to enable these ports in order to have your Kurento Media Server working:

Inbound

• 8888/TCP
• 50000-65000/UDP (RTP stream)

For security reasons, port 8888/TCP has to be opened specifying IP 35.180.105.193 as source address, that corresponds to our API server IP address.

Regarding RTP stream ports, you have to open these ports to any (0.0.0.0/0) or, if users connects from a VPN or specific IP, just open that IP address source.

Outbound

• 50000-65000/UDP (RTP stream)

Outbound stream needs to comprehend in its destination networks the same networks specified as source on inbound rule; this rule can be opened to “any” without causing any security issue.

maxPort=65000

• In order to configure STUN and external address, modify file:

/etc/kurento/modules/kurento/WebRtcEndopoint.conf.ini

• Modify stunServerAddress and stunServerAddress values indicating selected parameters, for example: 

stunServerAddress=stun.l.google.com

stunServerPort=1932
