What are the implications of the "public port" setting?

Question

One of the settings for a MarkLogic app server is "public port" (true/false).

The setting description in the Admin UI says:

Whether the port is accessible from the public internet.

The help tab's description is:

specifies whether this port can be accessed by anyone on the internet.

I don't see any reference to this setting in the documentation.

What are the implications of this setting?

Answer 1

Documentation is sparse, but I believe this was added in order to facilitate Data Hub Service and more fine grained security controls and management.

For a local install I don't think it has any impact.
