Wide Area Networks (WANs)
A Wide Area Network (WAN) provides connectivity to the internet or a remote network. A WAN
configuration consists of the following:
A physical device, such as an Ethernet device.
n
Several networking parameters for the WAN, such as firewall configuration and IPv4 and IPv6
n
support.
Several parameters controlling failover.

Configure WAN priority and default route metrics
The Connect EZ device is preconfigured with one Wide Area Network (WAN), named ETH1. You can
also create additional WANs and WWANs.
When a WAN is initialized, the Connect EZ 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 EZ device's WAN (ETH1) 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 ETH1. 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
