Custom Developer Images
To extend the base unit functionality provided by the gateway firmware, you can install developer
software images onto an overlay file system and adapt the gateway to specific needs. Developer images
can be created for custom applications and middleware, and to control third-party expansion cards.
Option licenses a software development kit which allows third parties to design developer images. For
information on the Option CloudGate developer program, contact Option Customer Support.

Network Interfaces
For connecting to the Internet, the base unit comes with an Ethernet interface and a WWAN (3G)
interface. An optional WLAN interface is available only when the
While the WWAN network interface is always a direct connection to the Internet, or WAN, the Ethernet
interface and optional WLAN interface can act as either a WAN or a local Area Network (LAN). The LAN
interface allows local devices to connect to the Internet through the gateway.
The network interfaces available on the gateway are:
Ethernet interface: can be a WAN or LAN connection depending on the behavior of the
switchover feature
at start-up or can be set manually.
WWAN interface: always a WAN connection because it connects directly to the internet.
WLAN interface: optional Wi-Fi expansion card can be configured as either a WLAN client, which will
act as a WAN interface, or as a WLAN access point, which will act as a LAN interface.
Choosing a WAN or LAN Interface
The gateway can have only one WAN connection at a time. However the gateway can be connected to
several different LAN networks simultaneously.
In choosing the network interface, you can specify:
Manual: the network interface is selected through the embedded web interface on the Home page.
Automatic: a priority list defines which network interface to use to connect to the WAN/internet.
The network interface at the top of the list will try to connect to the WAN/internet first. If this
succeeds then the gateway continues to use this network interface to connect to the WAN/internet.
If the connection to the internet fails, the gateway tries the second interface in the priority list and
so on. The priority list is defined in the embedded web interface on the Home page.
