[stunnel-users] ssl3_get_record:wrong version number

what I´m trying to accomplish is to build a secure RDP Connection between my
Laptop and a Server, which are in the same Network but as RDP in itself is
not secure enough I need the stunnel encryption. 

As of now I can establish a connection but as soon as I try to start an RDP
Connection I get the following message:

SSL_accept: 1408F10B: error:1408F10B:SSL routines:ssl3_get_record:wrong
version number

I tried serveral things for example: 
sslVersion = all

options = NO_SSLv2



Sadly this doesn´t work either as I get a different error after that.


This is pretty much the config for both Server and Client.


; R.B. Konfiguration HMailServer InvNr. 4522 RDP Zugriff mit


CAfile = certs.pem

accept = 9000

connect = 3389

;verify = 4

verifyPeer = yes

verifyChain = no

sslVersion = all



cert = stunnel.pem


I exchanged the certificates between the Server and the Laptop but can´t
establish a connection to get a RDP Session going.


Hope someone can help me.


Kind regards.





Mit freundlichen Grüßen
