e. Set the packet size to 256 bytes:
(config network interface wan1 ipv4 surelink target 0)> ping_size 256
(config network interface wan1 ipv4 surelink target 0)>
f. Set the host to ping:
(config network interface wan1 ipv4 surelink target 0)> ping_host
43.66.93.111
(config network interface wan1 ipv4 surelink target 0)>
1. Repeat the above step for the cellular WWAN (wwan) interface to enable SureLink on that
interface.
4. Save the configuration and apply the change:
(config)> save
Configuration saved.

5. Type exit to exit the Admin CLI.
Depending on your device configuration, you may be presented with an Access selection
menu. Type quit to disconnect from the device.

Using Ethernet devices in a WAN

The LR54 device has four Ethernet devices, named ETH1, ETH2, ETH3, and ETH4. 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 WAN1, 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, ETH3, and ETH4 devices are by default configured as part of a bridge named LAN1 that is
used by the LAN1 interface, which uses the Internal firewall zone. If desired, you can assign these
Ethernet devices to a WAN.

Using cellular modems in a Wireless WAN (WWAN)

The LR54 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 LR54 device cannot connect to the network using SIM1, it
