A have an application server that serves a number of IIS 8.5 applications on a number of IP's. Some use port 80 only, some use port 443 only, some use 80 & 443.
For the sites that use 443 only, we do not want IIS to listen on port 80 for those IP addresses. If someone tries to access http://securesite.domain.com we do not want them to get a 404 not found, we do not want the server to respond at all (e.g. Server not found)
One option would be to use a firewall, including Windows firewall, but I was hoping I could just stop IIS from listing on port 80 for those specific IP's, while still listening on port 443, or any other bound port for that matter. I hoped iplisten had a port option, but alas it does not.
Note: I have ensured there are no sites using a wildcard biding on port 80. All sites are bound to specific IPs/ports. Am I missing somthing simple?
