Can a Backend Server Access Its Load Balancer?

Generally, you are not advised to use a server as both a backend server and a client.

If you have special requirements, select a solution with caution.

Public network communication: If a backend server has a public IP address, it can access the public IP address of the associated load balancer.
Private network communication:
- The backend server can access the associated load balancer at Layer 7.
- If Transfer Client IP Address is enabled for Layer 4 listeners, the backend server cannot serve as a client and access the associated load balancer.
- If Transfer Client IP Address is not enabled for Layer 4 listeners, the backend server can serve as a client and access the associated load balancer.
  Note
  If IP as a Backend is enabled for the load balancer, Transfer Client IP Address settings will not be applied. In this case, the backend server can serve as a client and access the associated load balancer.
