Figure 35 – NAT Enabled, RF (Private), Ethernet (Private)
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. Figure 36 shows how the packets
will be modified as the packets pass through the network.
Figure 36 – Packet Flow: Ethernet and RF (Private)
Figure 37, the RF interface of Viper (2) is considered private. NAT is disabled for Viper (1). Viper (1) changes the source
address of the packet, making Viper (2) believe that the packet originated from the RF network.
