Subject: RE: [stunnel-users] FW: Stunnel with IIS8 on server 2012 64 bit Hi Jose, I made the changes you suggested, but I am still getting the same behavior. My external address is: https://website.company.com/website I am not adding any ports to the address. Thanks so much for your help! Michael From: Jose Alf.

Michael Drew; [email protected] Subject: Re: [stunnel-users] FW: Stunnel with IIS8 on server 2012 64 bit Michael, I guess what you want to do is to be able to connect to your internal Webserver via your Win2012 stunnel proxy using a URL like: https://yourwin2012dnsname:9001/ <https://yourwin2012dnsname:9009/> if that is correct, I suggest to adjust your configuration as follows: 1. Your stunnel mode must be server, not client. So adjust your service stanza as follows: [CLI9F529A0A] accept=9001 connect=10.xxx.xxx.xxx:9009 client=no 2. In your current configuration stunnel is listening only in the localhost ipv4 address (127.0.0.1). Therefore, you can only connect when you are logged on the server, you can't connect from a remote client. Hope this helps you clarify what's going on. Regards, Jose From: J.
