Active remote cluster in ECK

I am trying to add a remote cluster within a kibana deployed in kubernetes, but it asks me to enter the seed of the remote node. From what I see port 9300 is not exposed.

How can this communication be done?


Kibana uses port 9200 (http).

I am trying from the same Kibana to visualize multiple cluster of elasticserach. I don't know how it should be set. Both ports do not connect.
