I am trying to add a new node to the existing cluster of elasticsearch (v 2.3.4). I have public ip as well as private ip for the new virtual machine I have created.  
In yml file, below changes are done  
[cluster.name](http://cluster.name): myclustername  
discovery.zen.ping.unicast.hosts: I have tried both ip's along with port 9200 and 9300.  
The new node is not getting added to the cluster. Is there any other setting I need to do?

You need to set `network.host` on both nodes. Otherwise they can't communicate as they are only listening on 127.0.0.1 by default.
