It is possible to arrange this through a proxy. I have a WireGuard that has the internal IP address of the participants.
Let's take an example from a server that connected VPN with IP address: 10.8.0.2 (internal IP address)
VPN IP address: 10.8.0.2
You need to install on your vps a vpn which creates a local network.
I have wireguard.
Then set nginx as proxy.
once installed, open a browser and enter the IP address of your vps.
If the nginx greeting opens.
This is good.
It should work something like this: a request comes to vps, nginx processes it and sends information to the connected server via vpn (WireGuard), waits for a response and sends it back to who sent the request.
It remains to fix the config.
vpn nginx config
enter code here
server {
client_body_timeout 5s;
client_header_timeout 5s;
listen 80; #port
server_name 2.16.136.1;# domen/ip vpn

}
PS: sorry for config typos if there are any.
