Change URL access

[#1]

I would like to hide local ip (Qlikview server) from my IIS server for security reasons, have two separate servers.

Default URL looks like this: http://host_name:4750/QvAJAXZfc/AccessPoint.aspx?open=&id=QVS@host_name|mount_folder/SampleTest.qvw&client=Ajax

So the name of the server appears instead of the QVS@host_name (IP address) the other host_name (in blue) is the internet dns (no problem with this).

There is a tab called documents in the QEMC configuration that have an AJAX access method URL but I'm not sure how It works.

Is there a tech document that you can point me out with this best practices about security and internet?

Thanks in advance.
