I've been asked to do this before, but I just don't know an easy way to tell IIS (we're running 7.5) to block all requests coming from a specific country/countries. Does anyone know? I knew of an older ISAPI add-in called GeoSniper, but it dosn't seem to work in IIS 7.5.
Thanks for pointing out this question has been asked before. I was relying too much on the auto-suggestion bit. Following some of those threads, I'm going to go with translating the .htaccess produced by blockacountry.
