2. Notes

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.

#Example iptable
#Allow transcoders to reach the Plex Media Server
iptables -A INPUT -p tcp --dport 32400 -i eth0 -s <transcoderIP> -j ACCEPT
#Deny all other incoming connections
iptables -A INPUT -p tcp --dport 32400 -i eth0 -j DROP
