R450™ DC or R450™ MC Backhauls
There are two different types of backhaul options available for the R450 DC and R450 MC:
Ethernet and cellular. The network setup is slightly different for each type, depending on the
method used.
Network (Ethernet) R450™ DCs or R450™ MCs
The R450 DCs and R450 MCs are installed inside the utility network and there are very few
firewall considerations.
Figure 18 – Fixed Network System Architecture – Ethernet Bakhaul
The R450 DCs and R450 MCs require either dynamic or static IP addresses. Static IP
addresses are more reliable and secure for firewall maintenance as ports can be opened for
specific addresses rather than a range of addresses assigned by the IT network administrator.
Regardless, a list of IP addresses or ranges must be made available prior to R450 DCs or
R450 MCs configuration and activation.
An external IP address is required for the database. R450 DCs and R450 MCs can connect to
the external address through a DMZ. The external address can use NAT (network address
translation) to point to the internal address.
