I've been trying to get IP Address restrictions working on a website. When I change the feature settings for unspecified clients to deny, on one server it works fine and immediately blocks everyone but on the other it has no effect. I feel like I'm missing something really simple?
Both servers are patched up to date running 2012R2 and IIS 8.5. The only differences are that the server it works on is stand alone and hosted locally. The server it doesn't work on is hosted in Azure, it was part of a shared configuration cluster but I've removed that now.
Any ideas?
