Elasticsearch: connection issue

Elastic Stack Elasticsearch
1

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.
