I want to connect 3 external PCs. Three internal devices tested have been connected correctly. I want to set it to communicate with an external PC. Testing Elasticsearch.yml on the internal network --------------------- pc1 ---------------- cluster.name: "test-cluster" node.name: "master" node.master: true node.data: false transport.tcp.port: 9300 http.port: 9200 discovery.seed\_hosts: ["192.168.0.x1:9300","192.168.0.x2:9301","192.168.0.x3:9302"] cluster.initial\_master\_nodes: ["master"] network.host: 0.0.0.0 --------------------- pc2 ---------------- cluster.name: "test-cluster" node.name: "data1" node.master: false node.data: true transport.tcp.port: 9301 http.port: 9201 discovery.seed\_hosts: ["192.168.0.x1:9300","192.168.0.x2:9301","192.168.0.x3:9302"] cluster.initial\_master\_nodes: ["master"] network.host: 0.0.0.0 --------------------- pc3 ---------------- cluster.name: "test-cluster" node.name: "data2" node.master: false node.data: true transport.tcp.port: 9302 http.port: 9202 discovery.seed\_hosts: ["192.168.0.x1:9300","192.168.0.x2:9301","192.168.0.x3:9302"] cluster.initial\_master\_nodes: ["master"] network.host: 0.0.0.0 This works very well. * * * but, I want an external network connection, not an internal network connection. 218.xxx.xxx.xxx Open port: 9200, 9300,5601 182.xxx.xxx.1 Open port: 9211,9212 182.xxx.xxx.2 Open port: 9311,9312 elasticsearch.yml --------------------- 218.xxx.xxx.xxx---------------- cluster.name: "test-cluster" node.name: "master" node.master: true node.data: false transport.tcp.port: 9300 http.port: 9200 discovery.seed\_hosts: ["218.xxx.xxx.xxx:9300","182.xxx.xxx.1:9311","182.xxx.xxx.2:9312"] cluster.initial\_master\_nodes: ["master"] network.host: 0.0.0.0 --------------------- 182.xxx.xxx.1---------------- cluster.name: "test-cluster" node.name: "data1" node.master: false node.data: true transport.tcp.port: 9311 http.port: 9211 discovery.seed\_hosts: ["218.xxx.xxx.xxx:9300","182.xxx.xxx.1:9311","182.xxx.xxx.2:9312"] cluster.initial\_master\_nodes: ["master"] network.host: 0.0.0.0 --------------------- 182.xxx.xxx.2---------------- cluster.name: "test-cluster" node.name: "data2" node.master: false node.data: true transport.tcp.port: 9312 http.port: 9212 discovery.seed\_hosts: ["218.xxx.xxx.xxx:9300","182.xxx.xxx.1:9311","182.xxx.xxx.2:9312"] cluster.initial\_master\_nodes: ["master"] network.host: 0.0.0.0 The process is running on each PC. 218.xxx.xxx.xxx Search 182.xxx:9211 on Google on PC The Json format information screen that appears when executed is displayed. However, when I index it, I get a warning message. "master not discovered yet" There is no port forwarding problem. Please let me know if there are any settings I have missed. ---

Try the following config on each node: --------------------- 182.xxx.xxx.2---------------- cluster.name: "test-cluster" node.name: "data2" node.master: false node.data: true transport.tcp.port: 9312 http.port: 9212 discovery.seed\_hosts: ["218.xxx.xxx.xxx:9300","182.xxx.xxx.1:9311","182.xxx.xxx.2:9312"] cluster.initial\_master\_nodes: [" **218.xxx.xxx.xxx**"] network.host: **182.xxx.xxx.2** **WARNING: it is not encouraged to expose elasticsearch nodes directly over the internet** ---

Thank you for your reply. Thanks for the warning. All of the above information is false information. 182.xxx.1 / 2 These two PCs are a vm environment. network.host:ip:port Can you write like this? ---

I don't understand, maybe the docs help you: [https://www.elastic.co/guide/en/elasticsearch/reference/current/network.host.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/network.host.html) [https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-discovery-bootstrap-cluster.html](https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-discovery-bootstrap-cluster.html) ---

Thanks for the kind answer. However, the link has already been confirmed. I didn't understand the link. My question is wrong. 182.xxx.1 182.xxx.2 \<\< ip was recorded incorrectly. 182.xxx.1 VM 10.0.2.15-docker-172.17.0.2 Port: 9211, 9311 182.xxx.1 VM 10.0.2.16-docker-172.17.0.2 Port: 9212, 9312 It is like this. network.host: ?? How should I use it? ---

In this setting you can either write down the IP of the server or FQDN IP: ``` network.host: 182.xxx.1 ``` or FQDN: ``` network.host: my_server.my_domain.com ``` ---

I solved it by adding 'network.publish\_host:'. Thank you so much ---
