How to forward ports in VPN on another PC?

Question

VPN

There is
a Server on Windows Server 2016 Core with a white IP on which a DNS record was created in Cloudflare . WireGuard is hosted
on the same server and another PC with a gray IP address is connected through the tunnel.
The PC has OpenServer installed with the website.
It is necessary that when accessing the domain, the user receives a site hosted on a PC.

I tried forwarding port 80 from the server to the IP address of the computer in the VPN, it did not work

Answer 1

as an option, using the reverse proxy installed on the win server,
for example, nginx config
example:

http {

    server {
        listen 80;
        server_name my-public-domain.com;
        location / {
            proxy_pass http://192.168.1.123:8080/;
            include proxy.conf;
        }
    }

}

proxy.conf:

proxy_redirect          off;
proxy_set_header        Host            $host;
proxy_set_header        X-Real-IP       $remote_addr;
proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header        X-Forwarded-Proto $scheme;
client_max_body_size    1024m;
client_body_buffer_size 128k;
proxy_connect_timeout   900;
proxy_send_timeout      900;
proxy_read_timeout      900;
proxy_buffers           32 4k;
