How to make friends with a domain RDP multiple servers?

Question

System administration

I have X employees, X servers, somewhere I previously saw the practice of changing the connection port to RDP, for example
123.123.123.123:4040
and used this practice for a long time, but now the moment has come when these IPs are already a dime a dozen and I want to ennoble them with a domain , but the problem is that the domain does not allow you to specify the port, in addition, if there are 5 servers on one ip, how to understand where to send someone? I have an nginx server, but for me it's somehow not right to send things like RDP through the web server

Answer 1

Remote Desktop Gateway is a standard component of Windows Server. Outside, port 443 sticks out, inside - the usual 3389. Ports can be changed. Inside the RDG itself, configure the CAP (to) and RAP (to) policies. For more specific settings, you can use NPS (set automatically when installing RDG). For internal clients, the use of RDG can be disabled.
Outside, RDG can be set independently (if, for example, two network interfaces are used) or through, for example, Haproxy

Answer 2

rdp does not support srv record, so in your case if you already have nginx then go through it :(
