Windows – Data Channel Port Range box in IIS Manager is disabled

amazon ec2ftpiiswindowswindows-server-2012

I'm setting the FTP on IIS on my Amazon. I already make it work and can connect if I'm directly on the Amazon server. When I connect from outside, I can connect and accept login, but I cannot list the folder files.

I'm following the instructions here:
https://docs.microsoft.com/en-us/iis/publish/using-the-ftp-service/configuring-ftp-firewall-settings-in-iis-7

In this image show you need to enter the port so passive mode works.

But in my PC this field is not editable.

And as is mentioned also in the page you link to:

Go to IIS 7 Manager. In the Connections pane, click the server-level node in the tree.

I.e. the option can be set on server-level node only (for all sites on the server).

Not per FTP site:
