A transparent proxy (also known as an intercepting, inline, or forced proxy) intercepts normal communication at the network layer without requiring any special client configuration, as shown in the following figure. Customers do not need to be aware of the existence of the proxy.
The solution does not support normal proxies. If the data center requires all traffic to use a proxy, configure a transparent proxy to process all traffic from the rack to handle it according to policy, separating between the zones on your network.
