6.7.3.3.2.1.2 RF Interface is Considered Private
Figure 47 - NAT on HiPR-900 Enabled: RF interface is 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 the HiPR-900 unit. In the
example Figure 48, the RF interface of the HiPR-900 (1) unit is considered private. The Ethernet interface
of the HiPR-900(2) unit is considered private.
Figure 48 - NAT Enabled on RF interface
Notice that in the example (Figure 48 and Figure 49) NAT is enabled on HiPR-900 (2) on the Ethernet
interface and that on the HiPR-900 (1) unit on the RF interface.
