I am using IIS8.5 to host a few internal and external sub domains. Everything is working prefect but I have one thing I would like to change and I have no idea where to start.
I have set each site http and https bindings and I require SNI since I have multiple sub domains and no external trusted wildcard cert.
When attempting to visit the external (http or https) IP address of my server I get a simple version of a 404 Not found page. (Not the normal iis 404 page)
When someone visits the external IP of my server I would like both http and https to refuse the connection / provide web page not available. I do not know how to stop serving the Not Found error and just refuse the connection and if that is not possible where is this simple 404 Not Found page located so I can modify it in some way.
Any help would be great. Thank you
