Securing ES cluster

Elastic Stack Elasticsearch
1

Hi

As part of ES clustering, I have mapped my ES ip to network.host. After that I see my elasticsearch is accessible for all machines/ip's. How to restrict elasticsearch to be accessible only within cluster nodes, not to others?
Should I need to implement a kind of proxy or open source elasticsearch has inbuilt way?

Regards
Ram
