</font> </div><div><div> <br>
<div><div>Hi guys, </div><div>I have a quick question. I am trying to use stunnel in client mode to encrypt traffic going to my server.</div><div>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. </div>
<div>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.</div>
<div>My stunnel conf file is here:</div><div>[Router]<br>client=yes<br>accept = <a rel="nofollow" href="http://192.168.1.121:55555" target="_blank">192.168.1.121:55555</a><br>connect = <a rel="nofollow" href="http://192.168.160.168:55443" target="_blank">192.168.160.168:55443</a></div>
<div>Can you please comment on this?</div>
<div>Best regards,</div><div>Denis</div>
