How to wrap old 2003 RDP server in SSL?

Question

Stunnel

In short, there is an old server on Win2003. And to it access under the RDP protocol.
How can I wrap RDP traffic in SSL without putting a certificate on the final 2003 server?
I've been playing around with the stunnel4 package, which is on a nearby Linux server.
For an HTTP server, everything is chocolate: HTTPS traffic goes to stunnel from a regular web browser, and it reaches the final server via flat HTTP, via 80/tcp - everything works fine.
But for RDP, the client cannot agree on the protocol and ciphers.
How to do it right?
On Linux is Ubuntu 18.04.1 LTS, regularly updated.

Roman get off the mare if she is dead. There are several cases when it is worth supporting it, but this is not your case. Just install a new server.
