That’s because the nginx server _is_ the one making the connection to  
the IIS instance.

You need to teach your application about the X-Forwarded-For (X-F-F)  
HTTP header, or tell IIS to log this header in place of the client IP.  
Failing that, you could look at using something like

, but that’s kind of overkill IMHO.

For all of these, you’ll need to add the client’s IP to the X-F-F  
header in nginx. A bit of very simple googling should teach you how to  
achieve this.
