Subject: Re: [stunnel-users] Using stunnel for RDP / Proxy / Firewall

I do this all the time.  The way I do it is to connect locally to RDP on
a non-stardard port.  In the RDP dialog box, I have 127.0.0.10:12121,
then in stunnel on the local side is:

[xxx-rdp]
accept = 127.0.0.10:12121
connect = server:12122
client = yes

on the remote side is

[rdp-incoming]
accept = 12122
connect = 3389
client = no.

Normally RDP listens for any connection to port 3389, so I found it was
easiest to get to to work by moving off that port.  Note that you have
to open port 12122 in the firewall on the remote side.  On the other
hand, you can close 3389 on the remote side which takes away an obvious
port for hackers.
