I don't think stunnel does host name lookup from ip. But you can try messing with your windows hosts file.

I'm pretty sure I can't be the first person who wanted to see reverse DNS name lookup in the stunnel log. I tried looking in the settings and documentation; but, didn't see anything related to this.

I currently have stunnel strip SSL from incoming https connections; which then passes the connections to a proxy before ultimately reaching my web server. So, the only easy way to see where incoming connections are coming from are in the stunnel log.
Below, is a small example of what my stunnel log looks like (no, those arent the real IPs [image: *:) happy]). The information below would be much more useful to me if it included the DNS names in addition to their numeric IP.
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.
