Data Communication
Note: The Raven forwards
messages to and from the
cellular network for only ONE
device per port. The Raven is a
one-to-one gateway and does
not have advanced routing
features required to do one-to-
many routing. The primary purpose of the Raven is to forward data from a
single device connected to one of the ports to the cellular
network and, ultimately, under most circumstances, to the
Internet in a one‐to‐one gateway configuration.
When the Raven obtains its IP address from Sprint, it also
obtains the network routing information necessary to forward
messages to their routers which can then forward on from
there. The Raven then acts as a router for the device connected
to it, forwarding to or from the cellular network.
Public and Private Mode
In Public Mode, the Raven will pass the IP address assigned by
the cellular network to the device connected to its port. Public
Mode is the default mode for the Raven.
If you need more control over which gateway address, device
address, and netmask that is given out by the internal DHCP
server, you can use the private host mode, *HOSTPRIVMODE,
and set the internal network IP addresses. The Raven will use
NAT to forward packets to the end device.
Tip: When using Public mode, Sierra Wireless recommends
connecting the modem directly to the computer or other end device.
Using a hub or switch may prevent the Raven from updating the IP
address of the end device when an IP address is received from the
cellular network.
In AceManager, the Private mode settings are part of the PPP/
Ethernet group.
