ES has to be able to listen on both ports 9200 and 9300. Does anyone know why AWS doesn’t allow ES to listen in port **9300**? Any Advice appreciated. ---

I don't know why but anyway you should not use that port. ---

Thanks David, if anyone knows why we should not use port 9300 , that would be great. cheers, Robert ---

The question is more why would you use it for? Knowing that the TransportClient is removed in 8.0. ---

Hi David, I am asking because one of our solutions running in AWS , looks to use that port, out of the box. We can manually adjust it, was just curious about using that port ( 9300 ) I am new to ES, so are you saying that in the next release of ES, that port will not be used at all for ES? thanks in advance. cheers, Robert ---

It is still used for node to node communication. As a client the only port to use is 9200. ---

Are you talking about AWS ES service on GovCloud? If so I do not believe they expose port 9300, which is needed by the transport protocol. As David suggested you would therefore even need to host it yourself or switch to using a HTTP based client. ---
