Using Ethernet devices in a WAN

The IX30 device has two Ethernet devices, named ETH1 and ETH2. You can use these Ethernet
interfaces as a WAN when connecting to the Internet, through a device such as a cable modem:
By default, the WAN/ETH1 Ethernet device is configured as a WAN, named ETH1, with both DHCP and
NAT enabled and using the External firewall zone. This means you should be able to connect to the
Internet by connecting the WAN/ETH1 Ethernet port to another device that already has an internet
connection.
The ETH2 device is configured as a LAN interface, named ETH2, which uses the Internal firewall zone.

Using cellular modems in a Wireless WAN (WWAN)

The IX30 supports one cellular modem, named Modem, which is included in a preconfigured Wireless
WAN, also named Modem.
The cellular modem can have only one active SIM slot at any one time. For example, Modem can have
either SIM1 or SIM2 up at one time.
Typically, you configure SIM1 of the cellular modem as the primary cellular interface, and SIM2 as the
backup cellular interface. In this way, if the IX30 device cannot connect to the network using SIM1, it
automatically fails over to SIM2. IX30 devices automatically use the correct cellular module firmware
for each carrier when switching SIMs.
Configure cellular modem
Configuring the IX30's cellular modem involves configuring the following items:
Required configuration items
Enable the cellular modem.
n
The cellular modem is enabled by default.
Determine the SIM slot that will be used when connecting to the cellular network.
n
Configure the maximum number of interfaces that can use the modem.
n
Enable carrier switching, which allows the modem to automatically match the carrier for the
n
active SIM.
Carrier switching is enabled by default.
Configure the access technology.
n
Determine which cellular antennas to use.
