Hi all.  
Maybe someone can help. I can't connect to elastic from other host.  
Elastic configured to bind on "network.host: 10.254.1.88"

Log shows the following:

> ```
> [2019-02-23T16:17:37,387][INFO][o.e.t.TransportService] [srv-monsc-tst] publish_address {10.254.1.88:9300}, bound_addresses {10.254.1.88:9300}
> [2019-02-23T16:17:37,407][INFO][o.e.b.BootstrapChecks] [srv-monsc-tst] bound or publishing to a non-loopback address, enforcing bootstrap checks
> 
> ```

netstat -tulpen:

> tcp 0 0 10.254.1.88:9200 0.0.0.0:\* LISTEN 995 43449 5756/java  
> tcp 0 0 10.254.1.88:9300 0.0.0.0:\* LISTEN 995 39894 5756/java

Curl from locahost shows:

> {  
> "name" : "elastic-tst",  
> "cluster\_name" : "elasticsearch",  
> "cluster\_uuid" : "DnmMuVTiST-iKeZtFQe4XA",  
> "version" : {  
> "number" : "6.6.1",  
> "build\_flavor" : "default",  
> "build\_type" : "rpm",  
> "build\_hash" : "1fd8f69",  
> "build\_date" : "2019-02-13T17:10:04.160291Z",  
> "build\_snapshot" : false,  
> "lucene\_version" : "7.6.0",  
> "minimum\_wire\_compatibility\_version" : "5.6.0",  
> "minimum\_index\_compatibility\_version" : "5.0.0"  
> },  
> "tagline" : "You Know, for Search"  
> }

I also made tcpdump at elastic node to capture incoming connection from other host. There were only incoming SYN requests without any response.

IP table doesnt have any rules.
