FAQ
Q: Does this affect performance?
A (Simple): No.
A (Full): No, this mod only reads connection packets and checks if they are using an HAProxy header. There is no hard operations happening. If anything, this should speed up logins as we patch players loading in to the world. We do this because the HAProxy handler handles connections on a different thread than the main server thread.
Q: Does this fix TCPShield connections?
A (Simple): Yes!
A (Full): Yes! You can actually turn proxy-protocol to enabled in your TCPShield panel and then your players' IPs will actually be parsed correctly by your server.
