e. Set the packet size to 256 bytes:
(config network interface eth1 ipv4 surelink target 0)> ping_size 256
(config network interface eth1 ipv4 surelink target 0)>
f. Set the host to ping:
(config network interface eth1 ipv4 surelink target 0)> ping_host
43.66.93.111
(config network interface eth1 ipv4 surelink target 0)>
1. Repeat the above step for the cellular Modem (modem) interface to enable SureLink on that
interface.

Using Ethernet devices in a WAN
The IX20 device has Ethernet devices, named ETH1ETH2. 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.
Using cellular modems in a Wireless WAN (WWAN)
The IX20 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 IX20 device cannot connect to the network using SIM1, it
automatically fails over to SIM2. IX20 devices automatically use the correct cellular module firmware
for each carrier when switching SIMs.
