Good day!
CentOS Linux release 8.2.2004 (Core)
there was installed (number "7.9.0") so what we need. open 9200 for only one IP. what I did
iptables -I INPUT -s myserverip/32 -p tcp -m tcp --dport 9200 -j ACCEPT
iptables -A INPUT -p tcp --destination-port 9200 -j DROP
14
network.host: 0.0.0.0
transport.host: my real server ip
http.port: 9200
and I want to open [http://myserverip:9200](http://myserverip:9200) everything is good and I get someinfortmation on page it is working
But after that configuration our programmer tell me that elastic doesn't work wih PHP.
He wants that He has get success from his IP to 9200 and php work with elastic
How can I do that open port for him like myserverip:9200 and that php and elasticserach work ?

If you can access Elasticsearch from other external hosts, then it's probably something with the code they have. It's hard to suggest more without details.
Please note that it is dangerous to expose Elasticsearch to the internet. Make sure you have setup Security access controls.
