Proxy Protocol Support

Proxy Protocol Support is a modification for Fabric and Quilt that provides support for Proxy Protocol (HAProxy) on your Minecraft server. This allows you to use solutions like TCPShield or other software (such as Nginx) to forward traffic and hide your server's real IP address. Without Proxy Protocol, the console would display the proxy's IP, but reading Proxy Protocol packets enables showing players' actual IP addresses. This mod works only on the server side and has no effect on the client part. It supports Minecraft versions from 1.14 to 1.21.1, and possibly snapshots (untested).
