4: LAN/Wi-Fi Configuration
Note: The LAN/WiFi tab in ACEmanager only appears when a Wi-Fi X-Card
is installed in the AirLink GX Series device. If a Wi-Fi X-Card is not installed,
this tab appears as LAN.
The primary purpose of the AirLink device is to route data between
one or more connected devices and the Internet via the mobile
network. The AirLink device has two modes you can use for
configuring a LAN—Private Mode and Public Mode.
Private and Public Mode
Private Mode and Public Mode are Sierra Wireless terms.
In Private Mode, the AirLink device itself has a routable IP address
from the MNO. Connected devices are assigned non-routable
(private) IP addresses, making the connected router or laptop not
directly accessible from the Internet.
In Public Mode the AirLink device passes the public routable IP
address from the MNO through to the connected device such as a
router or laptop, making the router or laptop publicly addressable for
Internet applications. Figure 4-1 shows the two types of
configurations.
