TLS transport in single node cluster

Elastic Stack Elasticsearch
1

Hi,

(Elasticsearch Version 7.12)
I'm securing my single-node ES cluster with TLS.

network.host: _site_
discovery.type: single-node

I've already successfully configured TLS over http for communication from outside with the cluster:

xpack.security.enabled: true
xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.keystore.path: mycert_with_key.pfx
xpack.security.http.ssl.keystore.password: ***

My question is about the transport layer:
As I understand, since there is only one node, there is no internode communication (port 9300) so no need to configure the xpack.security.transport.ssl.* stuff, right?

Thanks for information!
