To achieve this, we would have to disable the Use Proxy Port option.
To configure the Use Proxy Port setting on a service by using the configuration utility:
- Navigate to Traffic Management > Load Balancing > Services, and open a service.
- In Advanced Settings, select Traffic Settings, and unselect Use Proxy Port.
To configure the Use Proxy Port setting on a service by using the CLI:
At the command prompt, type:
set service svc -useproxyport NO
The Use Proxy Port option works only when the Use Source IP/ Use Client IP option is enabled on the Service/Service Group respectively.
Also, this option is enabled by default for TCP-based service types, such as TCP, HTTP, and SSL,
This will allow the backend server to see client IP and source port from which the client tries to connect.
