Interfaces
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:
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
n
support.
n Several parameters controlling failover.
Configure WAN/WWAN priority and default route metrics
The AnywhereUSB Plus device is preconfigured with one Wide Area Network (WAN), named ETH1,
and one Wireless Wide Area Network (WWAN), named Modem. You can also create additional WANs
and WWANs.
When a WAN is initialized, the AnywhereUSB Plus device automatically adds a Setup 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.
A ssigning priority to WA Ns
By default, the AnywhereUSB Plus 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 asthe primary WA N, and the Ethernet
connection asbackup
