This code is a simple demonstration of using the Go standard library to build a performant TCP proxy server that filters out traffic based on the country of origin. It isn't smart about traffic that has already been through another proxy, like a load balancer; there's nothing in the TCP/IP connection information that can be used to figure out the original source of the request. It also doesn't know anything about HTTP and proxy headers. It also doesn't handle IPv6 traffic. The data comes from , using the country-level dataset. A future version might support the city-level dataset.
