RDP over ILO4 SSH Tunnel using putty (plink)

Hi Everyone,

Our test lab is running a HPE ProLiant DL360 Gen9 ILO4 Firmware Version 2.55 System ROM P89 v2.52 (10/25/2017). It's NIC is connected to the test lab switch.

The ILO port is connected to the internal LAN network. Yes I realise TS passthrough was removed after ILO2

I'm using the following command so my local port 127.0.0.1:1521 can forward RDP to the test lab Server NIC on 3389

plink -v -x -a -T -C -noagent -ssh -L 127.0.0.1:1521:<test lab IP>:3389 administrator@ILO_IP -pw pass

Looking up host "ILO IP"
Connecting to ILO IP port 22
Server version: SSH-2.0-mpSSH_0.2.1
Using SSH protocol version 2

iLO Advanced 2.55 at Aug 16 2017
Server Name: SERVER
Server Power: On

When I run RDP on Windows 10, RDP returns "An internal error has occured"

ILO session returns:

</>hpiLO-> Opening forwarded connection to <test lab IP>:3389
Received disconnect message (by application)
Disconnection message text: Client Disconnect
Server sent disconnect message
type 11 (by application):
" Client Disconnect"
FATAL ERROR: Server sent disconnect message
type 11 (by application):
" Client Disconnect"

Is it possible to do this???

Checklist of things done:

NLA is disabled, ILO SSH port 22, RDP service on test lab server started.

I can always just use the ILO Integrated Remote Console app but RDP allows copy/paste and is superior IMO

SSH logging returns 

Incoming packet #0xc, type 0 / 0x00 (unknown)
00000000 00 01 01 63 74 2d 74 63 70 69 70 00 00 00 00 00 ...ct-tcpip.....
Outgoing packet #0x16, type 3 / 0x03 (SSH2_MSG_UNIMPLEMENTED)

Thanks.
