Wide Area Networks (WANs)
A Wide Area Network (WAN) interface can be an Ethernet, DSL, or cellular interface that connects to a
remote network, such as the internet.
Ethernet interfaces
Ethernet interfaces can be used as a WAN interface when connecting to a remote network, such as
the internet, through a device such as a cable or DSL modem.
By default, the eth1 interface is configured as a WAN interface with both DHCP and NAT enabled. This
means you should be able to connect to the internet by connecting the wan/eth1 interface to a
device that already has an internet connection.
By default, the eth2 , eth3 , and eth4 interfaces are configured as a LAN interface. If necessary, you
can assign these interfaces to a WAN. For more information on Ethernet interfaces and their
configuration, see
Ethernet interfaces on page 28 .
Cellular interfaces
The LR54 supports two cellular interfaces, cellular1 and cellular2 .
To use a cellular interface as a WAN interface, it must be configured to connect to the cellular
network. For more information on cellular interfaces and their configuration, see
Cellular interfaces
on page 32 .
DSL interface
The TransPort LR device supports one Asymmetric Digital Subscriber Line (ADSL) interface, dsl .
To use the DSL interface as a WAN interface, you must configure it to connect to the DSL network.
For more information on the DSL interface and its configuration, see
DSL interface on page 35 .
