Your posts are not formatted using `</>`.  
That may explain the limit.

I don't understand what is happening. You set `network host: _ec2_` but got:

```auto
[2016-07-11 09:57:33,797][INFO][transport] [dev-lambda-elastic-1] publish_address {127.0.0.1:9300}, bound_addresses {[::1]:9300}, {127.0.0.1:9300}

```

It does not make sense. Are you sure that your configuration is applied?

What happens if you set:

```auto
network host: 192.168.0.1

```

It should fail.
