Notice that in this example, the source address of the packet comes from the Remote network and not the
RF network, thus the HiPR-900 (2) unit does not do any source IP address translation on it (
Figure 51). In the previous example, the HiPR-900 (1) unit was changing the source IP address of the
packet, making the HiPR-900 (2) unit believe that the packet was originating from the RF network.
