Sierra Wireless EV-DO manual Data Communication, Public and Private Mode

Note: The PinPoint-E forwards messages to and from the cellular network for only ONE device per port. The PinPoint-E is a one-to-one gateway and does not have advanced routing features required to do one-to- many routing.

Data Communication and Host Modes

Data Communication

The primary purpose of the PinPoint‐E 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 PinPoint‐E obtains its IP address from Verizon, it also obtains the network routing information necessary to forward messages to their routers which can then forward on from there. The PinPoint‐E 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 PinPoint‐E 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 PinPoint‐E.

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 PinPoint‐E 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 PinPoint-E 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.
