M2M Cellular Gateway
Chapter 3 Basic Network
3.1 WAN
The gateway provides one or more WAN interfaces to let all client hosts in Intranet of the gateway
access the Internet via ISP. But ISPs in the world apply various connection protocols to let gateways or
user's devices dial in ISPs and then link to the Internet via different kinds of transmit media.
So, the WAN Connection lets you specify the WAN Physical Interface, WAN Internet Setup and
WAN Load Balance for Intranet to access Internet. For each WAN interface, you must specify its
physical interface first and then its Internet setup to connect to ISP. If the gateway has multiple WAN
interfaces, you also can assign physical interface to participate in the Load Balance function.
In Physical Interface, you can choose "Ethernet", "3G/4G", "USB 3G/4G" or "ADSL" based on the
supported interfaces of the gateway. In Internet Setup, you can choose adequate WAN type for
different kind of WAN interface. When the gateway has multiple WAN interfaces, load balance
function operates between these interfaces to maximize the WAN bandwidth utilization.
Index skipping is used to reserve slots for new function insertion, when required.
