Neptune Technology R900, User Manual, Page: 58 / 68

A static public / external IP address is required for the server. R450 DCs and R450 MCs can
connect to the public / external IP address through DMZ and firewall. The external address
uses NAT (network address translation) to point to the internal address.
The following ports are required to be open on the firewall, servers, and routers.
Port Purpose
UDP 123 NTP - R450 DC and R450 MC to access the server
TCP 2440 MobiLink - R450 DC and R450 MC communication with the server
TCP 2440 Collector database versions 2.6–
TCP 2500 Collector database versions 5.0+
Table 20 – Required Cellular Ports
Cellular data plans required for cellular modem provisioning are usually referred to as M2M
plans. For new systems, it is recommended to start with a large (2-GB to 4-GB / collector,
unlimited) data plan until usage can be assessed after several months. MIU, R450 DC, or
R450 MC installations can create added usage at project start. It is possible to provide an
estimate; however, the cellular account holder is responsible for any overage costs. Some
carrier plans include pooling multiple cellular devices into one large bucket of data, so make
sure the bucket equals number of collectors multiplied by 4-GB.
The carrier could require a SIM card and/or the IMEI, ESN, or MEID from cellular modem to
add to account and provision. The IMEI, ESN, or MEID are provided to the project / utility
stakeholders after R450 DCs and R450 MCs are shipped from the manufacturer, so the
account setup and provisioning can be completed by carrier.
If static IP addresses are desired for implementation, they must be requested during setup
and provisioning. GPRS with SIM cards have different APN for static IP versus dynamic IP. The
carrier also provides a static IP address for each modem or SIM.

Gateway Backhauls
R900 Gateway ports are the same for Ethernet or cellular. However, ports must be opened in
external firewalls for cellular to connect with server. Internal firewalls can also be challenging
for Ethernet when multiple networks are connected. It is important to verify all firewall ports
are set between R900 Gateway and server.

Gateway v4 Using Web Services
In addition to above server ports, the R900 Gateway v4 requires the following ports to be
opened for the firewall, servers, and routers for connectivity. These ports are subject to
change and additional ports could be needed in the future. The following ports are required
to be open on the firewall, servers, and routers.
