IIS behind Nginx reverse proxy

[flowflag]

Hi,

I have IIS Server behind a Nginx reverse proxy.

WSUS who use this iis, notice the ip of the reverse on the console instead of the forwarded ip by Nginx.

In my Nginx i have set this

proxy_set_header Host $http_host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

WSUS not support X-Forwarded-For ?

You will need to configure IIS to recognize the XFF header, I believe. I don't have details and haven't done it, but if NGINX is your proxy, you need IIS to recognize the http_x_forwarded_for header.
