Wide Area Networks (WANs)
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

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

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
