In a transparent ProxySG deployment, what value does the TCP packet sent to the origin content server have as the source IP address?

In a transparent ProxySG deployment, the source IP address of the TCP packet sent to the origin content server is configured to reflect the client's IP address if this setting is enabled on the ProxySG. This feature is crucial in maintaining the visibility of client requests to the origin server, enabling better tracking and logging of requests at the application level.

When enabled, the ProxySG uses a technique called X-Forwarded-For (XFF), which allows the original client IP to be preserved in the request headers. This way, the server receiving the request can see the real client IP instead of just the ProxySG's IP address. This is particularly important for applications that rely on client identification for functionality like access control, personalized services, or analytics.

In contrast, if the setting were not enabled or implemented differently, the source IP sent to the origin server would default to the ProxySG's IP address, which would obscure the client's actual identity. Thus, understanding the importance of configuring client IP preservation in proxy deployments is vital for ensuring that application intelligence and proper logging practices are maintained.
