Elasticsearch Ports apart from 9200 and 9300

[Divit_Sharma]

Which other ports do elasticsearch uses apart from 9200 and 9300?

Can I use 9201 for kibana assuming that Elasticsearch won't use other port in 920* ranges? What issues it could create?

That's fine. You can use 9201 for Kibana if needed.

Thanks for the reply.

To answer your question, ES normally uses only 9200 (HTTP, i.e. from clients) and 9300 (Transport, i.e. between nodes) normally, though I suppose it might use others for some SSO or other options, but certainly not by default for most users.

More generally, I usually use the normal 5601 for Kibana if possible, just for simplicity, unless you are doing a single range-based security group or FW rule or ACL, in which case 9201, 9261, etc. work for a range 9200-9300.
