-All the requests to this Plex Media Server should pass by the UnicornLoadBalancer, if someone reach the server directly without passing through UnicornLoadBalancer he will not be able to start a stream, since FFMPEG binary has been replaced. It is recomended to setup a nginx reverse proxy in front to setup a SSL certificate and to have an iptable to direct access to the users on port 32400.
+All requests to the Plex Media Server should pass through the *UnicornLoadBalancer*, if someone reach the server directly he will not be able to start a stream, since FFMPEG binary has been replaced. To solve this problem it is recomended to configure an iptable to drop direct access on port **32400**.
