Hello,
Thank you for reaching out to us regarding this,
Could you please specify the version of RDM you are currently using?
What type of data source are you using?
Those three fields split into two different endpoints: the proxy itself, and the
RDP server you actually want to reach.
Host and its Port, at the top, are your PROXY_IP and PROXY_PORT, that's the HTTP
proxy server itself.
Username and Password only need to be filled in if that proxy enforces Basic
authentication; otherwise, leave them blank.
Remote host and its Port, defaulting to 3389, are the RDP server you're trying to
reach, going through the proxy.
Local host and its Port define the local loopback endpoint Remote Desktop Manager
opens on your machine to carry the tunnel, and in most cases you can leave that on
its default and let RDM pick the port automatically.
So concretely: Host = PROXY_IP with Port = PROXY_PORT, Remote host = your target
RDP server's address with Port = 3389, and Local host left on default.
Best regards,
