the traffic is accepted at firewall then forwarded to private load-balancer on oracle cloud, the forwarded to internal web servers. the problem is that client IP address at we server is seen as load-balancer IP address. is there a way to add X-Forwarded-for or X-real-IP in order to see actual IP address on internal web server.
The Loadbalancer may be configured to use TCP as opposed to HTTP. This can cause the header to not be added correctly. Try reconfiguring the loadbalancer to use HTTP
