Let's say I have a Server A with a valid certificate and a Server B with the key for the certificate.
Client === Nginx Proxy with valid cert === Apache with key
I don't want Ngnix to decrypt all traffic like a MITM. Nginx should pass all encrypted traffic to Apache without leaking the IP-Address of Apache.
If that is possible how do I now set up a "reverse Proxy" with nginx and apache as the upstream server?
