Hi Jose,
Thank you for your reply. I double checked and actually there is SSL handshake. Sorry, it was my mistake I did not analyze WireShark capture carefully.
But handshake failed and here is stunnel log:

Denis,
Looks like your configuration is incomplete. Check the sample stunnel.conf file in the stunnel distribution. Read the man page. Post your log file.
Try adding lines like these before [Router]
sslVersion = SSLv3
cert=stunnel.pem key=stunnel.pem
# Authentication stuff, try 0 for test verify = 0
CApath = /your/CAcerts/path
debug = 7 output = stunnel.log

Hi guys, I have a quick question. I am trying to use stunnel in client mode to encrypt traffic going to my server. Basically, I have a server which listens for SSL connection. And I have a client which can not do SSL but it needs to communicate with server over SSL. I setup stunnel in client mode to accept unecrypted traffic from client and redirect it to server over SSL. I checked TCP traffic with WireShark between stunnel and my server and I can see that there is no SSL handshake, stunnel makes TCP connection with server and sends some TCP packets but I expect to see SSL handshake. My stunnel conf file is here: [Router] client=yes accept = 192.168.1.121:55555 connect = 192.168.160.168:55443 Can you please comment on this? Best regards, Denis
