GeoFence is a fast TCP reverse-proxy to block countries from connecting to your service. Written to whitelist players in my community accessing my minecraft server while keeping out the bots.
To determine the country of an address, GeoFence uses the GeoLite2 IP Database. Sign over your firstborn to Maxmind to receive a copy of their binary database.
