Hi Warkolm,

For the first node is in machine 1:
cluster.name: sql
node.name: engineering
node.master: true
node.data: true
network.host: 127.0.0.0
transport.tcp.port: 9300-9400
http.port: 9200
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: [?]
index.number_of_shards: 2
index.number_of_replicas: 1
network.bind_host: 127.0.0.0
network.publish_host: 127.0.0.0

Second node is in second machine:
cluster.name: sql
node.name: team
node.master: false
node.data: true
network.host: 127.0.0.0
http.port: 9200
transport.tcp.port: 9300-9400
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: [?]
index.number_of_shards: 2
index.number_of_replicas: 1
network.bind_host: 127.0.0.0
network.publish_host: 127.0.0.0

Are the changes correct for my nodes? what should I place for the discovery.zen.ping.unicast.host?
