Can you describe more about your usage scenario?

[Nats-ji]

I'm currently running a Minecraft server behind NAT. I want to use frp's XTCP mode for the reverse proxying, so the players can connect directly to the Minecraft server to reduce the latency. I also need to know the players' real IP addresses, however currently XTCP can't do that. I'm currently using TCP mode's proxy protocol to achieve this, but the TCP mode will add extra latency because all the traffic is routed through the frp server first. That's why I want to request the support of the proxy protocol in XTCP mode.

Got it.
