Hi<div><br></div><div>I&#39;m about to add stunnel to my buildroot embedded project (ARM926EJ-S) and I was hoping the list could answer a few performance questions?</div><div><br></div><div>I&#39;ve been looking for a way to encrypt the connections between my embedded units and my server. From what I understood about openvpn, the server </div>
<div>starts to give problems beyond 1024 &quot;concurrent sessions&quot; .... I&#39;m looking at a design that can handle 4K concurrent sessions....although it&#39;ll take a few</div><div>years to get that big.</div><div>
<br></div><div>My embedded devices have a GSM modem and setup a ppp0 interface over gprs. I&#39;m considering stunnel in the hope that I could have up to 3000 stunnel connections</div><div>coming into my servers. I say 3K because by the tike I reach this figure I hope to have implemented better switches and off load the overhead of the encrypted connection to </div>
<div>the switch.</div><div><br></div><div>The requirement is that the embedded &quot;non-ssl aware client&quot; will be able to communicate with the server over a secure tunnel.</div><div><br></div><div>Am I completely on the wrong road? .... could stunnel cater for something like this?</div>
<div><br></div><div><br></div><div>Thanks in advance!</div>
