Wide Area Networks (WANs) and Wireless Wide Area Networks
(WWANs)
A Wide Area Network (WAN) provides connectivity to the internet or a remote network. A WAN
configuration consists of the following:
n A physical device, such as an Ethernet device or a cellular modem.
n Several networking parameters for the WAN, such as firewall configuration and IPv4and IPv6
support.
n Several parameters controlling failover.
Configure WAN/WWAN priority and default route metrics
The Connect IT 4 device is preconfigured with one Wide Area Network (WAN), named WAN, and one
Wireless Wide Area Network (WWAN), named Modem. You can also create additional WANs and
WWANs.
When a WAN is initialized, the Connect IT 4 device automatically adds a default IP route for the WAN.
The priority of the WANis based on the metric of the default route, as configured in the WAN's IPv4
and IPv6 metric settings.
Assigning priority to WANs
By default, the Connect IT 4 device's WAN (WAN) is configured with the lowest metric (1), and is
therefor the highest priority WAN. By default, the Wireless WAN (Modem) is configured with a metric of
3, which means it has a lower priority than WAN. You can assign priority to WANs based on the
behavior you want to implement for primary and backup WANinterfaces. For example, if you want a
cellular connection to be your primary WAN,with an Ethernet interface as backup, configure the
metric of the WWANto be lower than the metric of the WAN.
Example: Configure cellular connection as the primary WAN, and the Ethernet
connection as backup
Required configuration items
n Configured WANand WWAN interfaces. This example uses the preconfigured WAN and Modem
interfaces.
n The metric for each WAN.
