In a transparent ProxySG deployment, what value is included in the TCP packet's destination IP address?

In a transparent ProxySG deployment, the correct value included in the TCP packet's destination IP address is the IP address of the origin content server. This is because a transparent proxy operates in a way that makes it invisible to the client. The client sends its requests directly to the original destination, which is the origin content server.

The ProxySG intercepts these requests and forwards them to the appropriate resource while keeping the original destination address intact in the TCP packet. This ensures that data flows between the client and the origin server without any alteration to the destination IP address by the transparent proxy. As a result, the proxy is able to analyze and manage traffic without requiring any configuration changes on the clients or the server, acting largely in the background.

In contrast, other options refer to addresses that do not correctly reflect the nature of a transparent proxy's operation. The ProxySG's IP address would not be the destination IP because the client is unaware of the proxy's presence in this deployment type. Similarly, the default gateway and intermediary server would not be the destination address for packets intended for the content server.
