I'm trying to bind the API to 127.0.0.1 and use the apache reverse proxy settings with kibana to talk to ES. This works as I expected. However, I need to bind the inter-cluster communication to a real IP address, supposedly with network.publish\_host, but this does not work. Both bind to 127.0.0.1 Running from the latest deb package, on ubuntu 12.04 from /etc/elasticsearch/elasticsearch.yaml network.bind\_host: 127.0.0.1 network.publish\_host: my.redacted.ip.address netstat -an | grep 9300 tcp 0 0 127.0.0.1:9300 0.0.0.0:\* LISTEN netstat -an | grep 9200 tcp 0 0 127.0.0.1:9200 0.0.0.0:\* LISTEN this is a major deal as I do not want to bind the api directly to a routable interface. from the docs: The network.bind\_host setting allows to control the host different network components will bind on. By default, the bind host will be anyLocalAddress (typically 0.0.0.0 or ::0). The network.publish\_host setting allows to control the host the node will publish itself within the cluster so other nodes will be able to connect to it. Of course, this can’t be the anyLocalAddress, and by default, it will be the first non loopback address (if possible), or the local address. The network.host setting is a simple setting to automatically set both network.bind\_host and network.publish\_host to the same host value. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

As far as I am aware you can't split the two, they both need to be on the same interface/IP. I don't know if this is a bug or if the docs are incorrect.

That doesn't make a lot of sense then. Why would you be able to set the publish host to something different if they both have to bind to the same interface? I'm not understanding what the purpose of these configuration bits is. I was also told in the IRC room that this was how you separated them a while back... I can't really believe that nobody else has run into this? Why would you want to bind your zero security direct access api to a routable layer 3 address if you don't have to? Kibana proxypass config is also set to use 127.0.0.1 as its bind, is it then expected that there is no cluster capability whatsoever? The only alternative I can think of is to bind it on 0.0.0.0 and then rely on host based firewall to only allow connection via 127.0.0.1 for 9200 and l3 ip for 9300, but this seems like something the app should be able to do.

Due to limitations of TCP/IP server socket bind, you can do the following: - just use network.host to configure an IP address. This is the most common case. - use network.bind\_host to a single internal IP address and network.publish\_host to a single external IP address on the same(!) network interface (also known as virtual IP address). ES uses the "bind all" address as a fall back if the bind fails. - use the "bind all" address = 0.0.0.0 (or IPv6 ::1) for network.host if you want to use different (=all) network interfaces you want ES to listen on The name "publish\_host" is a bit unfortunate. This is not a second IP address on another interface.

The [doc of Elasticsearch](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html) about `network.host` should be updated in order to reflect your three options. I've spent a lot of time searching for "bind\_all" since Elasticsearch 2.0. ---
**Author:** ![j16r](https://sea2.discourse-cdn.com/elastic/user_avatar/discuss.elastic.co/j16r/32/9676_2.png) [@j16r](https://discuss.elastic.co/u/j16r)\ **Post date:** [May 9, 2016, 10:32pm UTC](https://discuss.elastic.co/t/network-publish-host-does-not-seem-to-do-what-it-says-it-does/17055/7 "2016-05-09T22:32:15Z")
I've been trying this (as you suggested): ``` network.publish_host: _ec2:privateIpv4_ network.bind_host: 0.0.0.0 ``` As I want to be able to `curl localhost:9200` as well as `curl http://mycluster.org:9200`, and it appears that if you set `bind_host` to `0.0.0.0` independent of `publish_host`, it'll advertise its address as `127.0.0.1` and then you'll get this: > [2016-05-09 21:45:18,484][WARN][discovery.zen.ping.unicast] [client\_0] failed to send ping to [{#zen\_unicast\_1#}{127.0.0.1}{127.0.0.1:9300}] > SendRequestTransportException[[127.0.0.1:9300][internal:discovery/zen/unicast]]; nested: NodeNotConnectedException[[127.0.0.1:9300] Node not connected]; This doesn't really make any sense to me, I would expect `publish_host` to be the ip advertised to other elasticsearch instances, and `bind_host` only to affect how listen works. Furthermore if you happen to configure your cluster this way, it seems totally stuck in this fashion! ---
