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
https://devcentral.f5.com/weblogs/Joe/archive/2009/12/23/x-forwarded-for-http-module-for-iis7-source-included.aspx
, 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.

HTH,
Jonathan
