An IP packet whose source IP address originates from the RF network and is sent towards the Ethernet network will
have its source IP address replaced by the Ethernet IP address of Viper (2). Notice in this configuration the Ethernet IP
address for Viper (1) is considered private and the RF IP address for Viper (2) is considered private. The following figure
shows how packets will be modified as the packets pass through the network.
Figure 87 – Packet Flow, Ethernet and RF (Private)
In the following figure, the RF interface of Viper (2) is considered private. NAT is disabled for Viper (1). Viper (1)
