Examples of Failover action:
In your office you have a local network with cable
or ADSL as WAN connection, which uses Bytton
LTE as a backup link. You should set the Primary
Interface to “Ethernet port” and the secondary one
to the embedded mobile modem:
Figure 5-60: Example of setting up primary and secondary WAN Interfaces, using Failover.
In normal operation all computers in your local network
will reach the Internet via ETH port, so the Ethernet link
is up and the PPP link (GPRS/EDGE or UMTS/HSPA
modem) is disconnected:
The routing is done via 192.168.1.8 gateway in the Ethernet WAN network using the interface “wan”:

.
When the Ethernet link is broken, the PPP link goes up (online) automatically:
or:
and the access to Internet is performed through the HSPA modem (the “ppp1” interface) via generic
10.64.64.65 gateway.
