Overview
A Local Area Network (LAN) is a shared communication system to which many
computers are attached. A LAN is usually located in one immediate area such as a
building or floor of a building.
The LAN screens can help you configure a LAN DHCP server and manage IP
addresses.
7.1.1
What You Can Do in this Chapter
•
Use the
LAN
IP
screen to set the LAN IP address, subnet mask, and DHCP
settings (
Section 7.2 on page 145
).
•

ZyXEL Device sends to the DHCP client devices on the LAN (
Section 7.3 on page
146
).
•
Use the
UPnP
screen to enable UPnP (
Section 7.4 on page 148
).

What You Need To Know
The following terms and concepts may help as you read this chapter.
7.1.2.1
About LAN
IP Address
Similar to the way houses on a street share a common street name, so too do
computers on a LAN share one common network number. This is known as an
Internet Protocol address.
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your
ZyXEL Device will compute the subnet mask automatically based on the IP
address that you entered. You don't need to change the subnet mask computed by
the ZyXEL Device unless you are instructed to do otherwise.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows clients to obtain TCP/IP
configuration at start-up from a server. This ZyXEL Device has a built-in DHCP
server capability that assigns IP addresses and DNS servers to systems that
support DHCP client capability.
DNS
DNS (Domain Name System) maps a domain name to its corresponding IP
address and vice versa. The DNS server is extremely important because without
it, you must know the IP address of a computer before you can access it. The DNS
server addresses you enter when you set up DHCP are passed to the client
machines along with the assigned IP address and subnet mask.
7.1.2.2
About UPnP
How do I know if I'm using UPnP?
UPnP hardware is identified as an icon in the Network Connections folder
(Windows XP). Each UPnP compatible device installed on your network will appear
as a separate icon. Selecting the icon of a UPnP device will allow you to access the
information and properties of that device.

Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own
services and opening firewall ports may present network security issues. Network
information and configuration may also be obtained and modified by users in some
network environments.
When a UPnP device joins a network, it announces its presence with a multicast
message. For security reasons, the ZyXEL Device allows multicast messages on
the LAN only.
All UPnP-enabled devices may communicate freely with each other without
additional configuration. Disable UPnP if this is not your intention.
UPnP and ZyXEL
ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum
UPnP™ Implementers Corp. (UIC). ZyXEL's UPnP implementation supports
Internet Gateway Device (IGD) 1.0.
See
Section 7.8 on page 158
for examples of installing and using UPnP.
7.1.2.3
About File Sharing
User Account
This gives you access to the file sharing server. It includes your user name and
password.
Workgroup name
This is the name given to a set of computers that are connected on a network and
share resources such as a printer or files. Windows automatically assigns the
workgroup name when you set up a network.
Shares
When settings are set to default, each USB device connected to the ZyXEL Device
is given a folder, called a “share”. If a USB hard drive connected to the ZyXEL
Device has more than one partition, then each partition will be allocated a share.
You can also configure a “share” to be a sub-folder or file on the USB device.
File Systems
A file system is a way of storing and organizing files on your hard drive and
storage device. Often different operating systems such as Windows or Linux have
Page 144 / 404

P-661HNU-Fx User’s Guide
144
different file systems. The file sharing feature on your ZyXEL Device supports File
Allocation Table (FAT), FAT32, and New Technology File System (NTFS).
Common Internet File System
The ZyXEL Device uses Common Internet File System (CIFS) protocol for its file
sharing functions. CIFS compatible computers can access the USB file storage
devices connected to the ZyXEL Device. CIFS protocol is supported on Microsoft
Windows, Linux Samba and other operating systems (refer to your systems
specifications for CIFS compatibility).
7.1.2.4
About Printer Server
Print Server
This is a computer or other device which manages one or more printers, and
which sends print jobs to each printer from the computer itself or other devices.
Operating System
An operating system (OS) is the interface which helps you manage a computer.
Common examples are Microsoft Windows, Mac OS or Linux.
TCP/IP
TCP/IP (Transmission Control Protocol/ Internet Protocol) is a set of
communications protocols that most of the Internet runs on.
Port
A port maps a network service such as http to a process running on your
computer, such as a process run by your web browser. When traffic from the
Internet is received on your computer, the port number is used to identify which
process running on your computer it is intended for.
Line Printer Remote Protocol
The Line Printer Remote (LPR) Protocol is software that provides printer spooling
and print-server features using TCP/IP to connect printers and computers on a
network.
Supported OSs
Your operating system must support TCP/IP ports for printing and be compatible
with the LPR protocol.

The following OSs support ZyXEL Device’s printer sharing feature.
•
Microsoft Windows 95, Windows 98 SE (Second Edition), Windows Me, Windows
NT 4.0, Windows 2000, Windows XP or Macintosh OS X.

The LAN Setup Screen
Click
Network Setting > Home Networking
to open the
LAN Setup
screen.
Use this screen to set the Local Area Network IP address and subnet mask of your
ZyXEL Device and configure the DNS server information that the ZyXEL Device
sends to the DHCP client devices on the LAN.
Figure 39
Network Setting > Home Networking > LAN Setup
The following table describes the fields on this screen.
Table 24
Network Setting > Home Networking > LAN Setup
LABEL
DESCRIPTION
LAN IP Setup
IP Address
Enter the LAN IP address you want to assign to your ZyXEL Device in
dotted decimal notation, for example, 192.168.1.1 (factory default).
IP Subnet Mask
Type the subnet mask of your network in dotted decimal notation, for
example 255.255.255.0 (factory default). Your ZyXEL Device
automatically computes the subnet mask based on the IP address you
enter, so do not change this field unless you are instructed to do so.
