I'm using https://www.ip2location.com/blockvisitorsbycountry.aspx, but it's a rather tedious job to have to insert each and every IP range. I've also tried posting the IP blocking in my .httaccess file but receive an error 500 each time. I'm just trying to block IPs outside of my country from accessing my site---quite an extensive list.
Any other ideas/options since the Admin Tools Geographic Blocking isn't completely reliable?
Thank you.
