Proxy to TCP port with real IP (lemmy.world)

Simple question, difficult solution. I can't work it out. I have a server at home with a site-to-site VPN to a server in the cloud. The server in the cloud has a public IP.

I want people to access server in the cloud and it should forward traffic through the VPN. I have tried this and it works. I've tried with nginx streams, frp and also HAProxy. They all work, but, in the server at home logs I can only see that people are connecting from the site-to-site VPN, not their actual source IP.

Is there any solution (program/Docker image) that will take a port, forward it to another host (or maybe another program listening on the host) that then modifies the traffic to contain the real source IP. The whole idea is that in the server logs I want to see people's real IP addresses, not the server in the cloud private VPN IP.

Isn't that what the logs on the proxy are for?

This is only true if the proxy can understand the application layer of the backend (eg. HTTP). For TCP/UDP based proxy, you only get "X connected to Y" type of logs, which isn't very useful to debug an application.
