Using Ethernet devices in a WAN
The Connect IT 16/48 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 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 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 Connect IT 16/48 supports one cellular modem, named WWAN cellular modem, which is included
in a preconfigured Wireless WAN, also named WWAN.
The cellular modem can have only one active SIMslot at any one time. For example, WWAN cellular
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 Connect IT 16/48 device cannot connect to the network
using SIM1, it automatically fails over to SIM2. Connect IT 16/48 devices automatically use the correct
cellular module firmware for each carrier when switching SIMs.
