The NBG-418N extends the range of your existing wired network without additional wiring,
providing easy network access to mobile users.
Your can create the following connections using the NBG-418N:
• LAN. You can connect network devices via the Ethernet ports of the NBG-418N so that they can
communicate with each other and access the Internet.
• WLAN. Wireless clients can connect to the NBG-418N to access network resources.
• WAN. Connect to a broadband modem/router for Internet access.

• Change the password. Use a password that’s not easy to guess and that consists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the NBG-418N to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG-418N.
You could simply restore your last configuration.

2.1 Overview
This chapter describes how to access the NBG-418N W eb Configur ator and provides an overview of
its screens.
The Web Configurator is an HTML-based management interface that allows easy setup and
management of the NBG-418N via Internet browser. Use Internet Explorer 6.0 and later versions,
Mozilla Firefox 3 and later versions, or Safari 2.0 and later versions. The recommended screen
resolution is 1024 by 768 pixels.
In order to use the Web Configurator you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in
Windows XP SP (Service Pack) 2.
• JavaScript (enabled by default).
• Java permissions (enabled by default).

3.4 Connection Wizard: STEP 3: Internet Configuration
The NBG-418N offers three Internet connection types. They are Ethernet, PPP over Ethernet or
PPTP. The wizard attempts to detect which WAN connection type you are using. If the wizard does
not detect a connection type, you must select one from the drop-down list box. Check with your ISP
to make sure you use the correct type.
This wizard screen varies according to the connection type that you select.

3.4.2 PPPoE Connecti
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with
a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data
networks.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for instance, RADIUS).
One of the benefits of PPPoE is the ability to let end users access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily create
and offer new IP services for specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber’s site.
By implementing PPPoE directly on the NBG-418N (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the NBG-418N does that part of
the task. Furthermore, with NAT, all of the LAN's computers wi ll have Internet access.

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers of data from a
remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based
networks.
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks,
such as the Internet.
Refer to the appendix for more information on PPTP.

AN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated from
the Internet, for instance, only between your two branch offices, you can assign any IP addresses
to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has
reserved the following three blocks of IP addresses specifically for private networks.
Table 10 Private IP Address Ranges
10.0
.0.0
16.0.0
172.
168.0.0
192.
You can obtain your IP address from the IANA, from an ISP or have it assigned by a private
network. If you belong to a small organization and your Internet access is through an ISP, the ISP
can provide you with the Internet addresses for your local networks. On the other hand, if you are
part of a much larger organization, you should consult your network administrator for the
appropriate IP addresses.
Not
e: Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment,
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,
Guidelines for Management of IP Address Space.

3.4.6 IP Address and Subnet Mask
Similar to the w
share one common network number.
Where you obtain your network number depends on your particular situation. If the ISP or your
network administrator assigns you a block of registered IP addresses, follow their instructions in
selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user
account and the ISP will assign you a dynamic IP address when the connection is established. The
Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private
use; please do not use any other number unless you are told otherwise. Let's say you select
192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to
192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the
network number while the last number identifies an individual computer on that network.
Once you have decided on the network number, pick an IP address that is easy to remember, for
instance, 192.168.1.1, for your NBG-418N, but make sure that no other device on your network is
using that IP address.
The subnet mask specifies the network number portion of an IP address. Your NBG-418N 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 NBG-418N unless you are instructed to do otherwise.

This section gives you an example of how to set up wireless network using WPS. This example uses
the NBG-418N as the AP and NWD210N as the wireless client which connects to a notebook.
e: The wireless client must be a WPS-aware device (for example, a WPS USB adapter

or PCI card).
There are two WPS methods for creating a secure connection. This tutorial shows you how to do
both.

• Push Button Configuration (PBC) - create a secure wireless network simply by pressing a
button. See Section 5.2.1.1 on page 58.This is the easier method.
• PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the NBG-418N’s interface. See Section 5.2.1.2 on page 59.
This is the more secure method, since one device can authenticate the other.

The wireless network is the part in the blue circle. In this wireless network, devices A and B are
called wireless clients. The wireless clients use the access point (AP) to interact with other devices
(such as the printer) or with the Internet. Your NBG-418N is the AP in the above example.

• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific channel, or
frequency, to send and receive information.
• Every wireless client in the same wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network. It can also protect the
information that is sent in the wireless network.

network.
Normally , the AP acts like a beacon and regu larly broadcasts the SSID in the area. Y ou can hide the
SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change
the default SSID to something that is difficult to guess.
ou Should Know
ing sections introduce different types of wireless security you can set up in the wireless
This type of security is fairly weak, however, because there are ways for unauthorized devices to
get the SSID. In addition, unauthorized devices can still see the information that is sent in the
wireless network.
6.3.1.2 MAC Address Filter
wireless client has a unique identification number, called a MAC address.
Every
usually written using twelve hexadecimal characters
00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s
Guide or other documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to
use the wireless network. If a wireless client is allowed to use the wireless network, it still has to
have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the
wireless network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized
wireless client. Then, they can use that MAC address to use the wireless network.

6.3.1.3 Encryption
Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.
Table 25 Types of Encryption for Each Type of Authentication
We
akest No Security
Strongest WPA2-PSK
For example, if users do not log in to the wireless network, you can choose no encryption, Static
WEP, WPA-PSK, or WPA2-PSK.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. Suppose the wireless network has two wireless clients. Device A only supports
WEP, and device B supports WEP and WPA-PSK. Therefore, you should set up Static WEP in the
wireless network.
NO AUTHENTICATION
Static WEP
WPA-PSK
No
te: It is recommended that wireless networks use WPA-PSK, or stronger encryption.
IEEE 802.1x and WEP encryption are better than none at all, but it is still possible
for unauthorized devices to figure out the origi nal in formation pretty quickly.
When you select WPA2-PSK in your NBG-418N, you can also select an option (WPA Compatible)
to support WPA-PSK as well. In this case, if some wireless clients support WPA-PSK and some
support WPA2-PSK, you should set up WPA2-PSK and select the WPA Compatible option in the
NBG-418N.
Many types of encryption use a key to protect the information in the wireless network. The longer
the key, the stronger the encryption. Every wireless client in the wireless network must have the
same key.
6.3.1.4 WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a wireless network with strong security, without having to configure
security settings manually. Depending on the devices in your network, you can either press a
button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification
Number) in the devices. Then, they connect and set up a secure network by themselves. See how
to set up a secure wireless network using WPS in the Section 5.2.1 on page 57.

7.1 Overview
This chapter discusses the NBG-418N’s WAN screens. Use these screens to configure your NBG418N 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.

WAN IP Address
The WAN IP address is an IP address for the NBG-418N, which makes it accessible from an outside
network. It is used by the NBG-418N to communicate with other devices in other networks. It can
be static (fixed) or dynamically assigned by the ISP each time the NBG-418N 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).

versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, you must know the IP address of a computer before you can access
it.
The NBG-418N can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the NBG-418N’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.

(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL,
cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using
PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example Radius).
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a
function known as dynamic service selection. This enables the service provider to easily create and
offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no
specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the NBG-418N (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the NBG-418N does that part of
the task. Furthermore, with NAT, all of the LANs’ computers wi ll have access.

A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is a computer network limited to the immediate area, usually the same building or
floor of a building. The LAN screens can help you configure a LAN DHCP server, manage IP
addresses, and partition your physical network into logical networks.

9.1 Overview
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 NBG-418N’s LAN as a
DHCP server or disable it. When configured as a server, the NBG-418N 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.
9.2 What You Can Do
•Use the General screen to enable the DHCP server (Section 9.4 on page 97).
•Use the Advanced screen to assign IP addresses on the LAN to specific individual computers
