Hello,
I am attempting to configure a remote desktop gateway server with web access. So far I've gotten the web page to display, I set up a test remote app for the calculator, and I can configure internal RDP clients to use this server as a gateway. I've only got 2 ports open to the RDP Gateway/web server on our internal network via the Cisco firewall from the internet. These are ports 443 and 3389, and everything works so far when these 2 ports are open. When I close port 3389, it's breaks the functionality of the remote apps on the web page.
I was under the impression that web RDP didn't require 3389, and if it is required, what advantage does web RDP even have? What can I do to make Web RDP work purely over HTTPs? Thanks!
