<p>What would be the benefit? It would slow stunnel down. </p>

<div>Probable would want to add some code to filter out
private address. </div>

<div>Final step would be to scan original log and add the name

The information below would be much more useful to me if it included the DNS names in addition to their numeric IP.</div>

I currently have the latest Windows version of stunnel installed. It would be great to know how to get it to resolve DNS names as well in the log file; preferably without impeding general stunnel performance. I tried several debug levels; but none them did reverse DNS lookup. Hopefully someone know how to do this on a Windows stunnel setup.<br>
