Client List
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients to obtain TCP/IP configuration at start-up from a server. You can
configure the Device as a DHCP server or disable it. When configured as a server,
the Device provides the TCP/IP configuration for the clients. If DHCP service is
disabled, you must have another DHCP server on your LAN, or else the computer
must be manually configured.
Click
Status > Client List
to open the following screen. The read-only DHCP table
shows current DHCP client information (including
IP Address
,
Host
Name
and
MAC Address
) of all network clients using the Device’s DHCP server.

DESCRIPTION
Host Name
This indicates the computer host name.
MAC Address
Every Ethernet device has a unique MAC (Media Access Control)
address. The MAC address is assigned at the factory and consists of six
pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02.
This indicates the MAC address of the client computer.
IP Address
This indicates the IP address assigned to this client computer.

WAN Setup
5.1
Overview
This chapter discusses the Device’s
WAN
screens. Use these screens to configure
your Device for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another
network or the Internet. It connects your private networks (such as a LAN (Local
Area Network) and other networks, so that a computer in one location can
communicate with computers in other locations.

What You Can Do in this Chapter
• The
Mode
screen lets you set the Device to use PTM over ADSL (
Section 5.4 on
page 75
).
• The
Layer 2 Interface
screen lets you view, remove or add a layer-2 WAN
interface (
Section 5.5 on page 75
).
• The
Internet Connection
screen lets you view and configure the WAN settings
on the Device for Internet access (
Section 5.6 on page 80
).

What You Need to Know
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower
layer protocol. To set up a WAN connection to the Internet, you need to use the
same encapsulation method used by your ISP (Internet Service Provider). If your
ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPPoA,
they should also provide a username and password (and service name) for user
authentication.
WAN IP Address
The WAN IP address is an IP address for the Device, which makes it accessible
from an outside network. It is used by the Device to communicate with other
devices in other networks. It can be static (fixed) or dynamically assigned by the
ISP each time the Device tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the
subnet mask and DNS server IP address(es) (and a gateway IP address if you use
the Ethernet or ENET ENCAP encapsulation method).
ATM
Asynchronous Transfer Mode (ATM) is a LAN and WAN networking technology that
provides high-speed data transfer. ATM uses fixed-size packets of information
called cells. With ATM, a high QoS (Quality of Service) can be guaranteed. ATM
uses a connection-oriented model and establishes a virtual circuit (VC) between
two endpoints before the actual data exchange begins.
PTM
Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2
standard. In PTM, packets are encapsulated directly in the High-level Data Link
Control (HDLC) frames. It is designed to provide a low-overhead, transparent way
of transporting packets over DSL links, as an alternative to ATM.
5.3
Before You Begin
You need to know your Internet access settings such as encapsulation and WAN IP
address. Get this information from your ISP.

The Mode Screen
Click
Network > LAN > Mode
to open the
Mode
screen. Use this screen to set
whether or not the Device uses PTM over ADSL. Since PTM has less overhead than
ATM, some ISPs use PTM over ADSL for better performance. Select or clear the
option for PTM over ADSL and click
Apply
to save your changes.

The Layer 2 Interface Screen
The Device must have a layer-2 interface to allow users to use the DSL port
to
access the Internet. The screen varies depending on the interface type you select.
