CHAPTER 1
Getting to Know Your NBG-417N
1.1 Overview
This chapter introduces the main features and applications of the NBG-417N.
The NBG-417N extends the range of your existing wired network without
additional wiring, providing easy network access to mobile users. You can set up a
wireless network with other IEEE 802.11b/g/n compatible devices.
A range of services such as a firewall and content filtering are also available for
secure Internet computing.
1.2 Applications
Your can create the following networks using the NBG-417N:
• Wired. You can connect network devices via the Ethernet ports of the NBG417N so that they can communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the NBG-417N to access network
resources.
• WAN. Connect to a broadband modem/router for Internet access.

Chapter 1 Getting to Know Your NBG-417N
1.3 Ways to Manage the NBG-417N
Use any of the following methods to manage the NBG-417N.
• WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of
the Web Configurator to set up a wireless network with your ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the NBG417N using a (supported) web browser.
1.4 Good Habits for Managing the NBG-417N
Do the following things regularly to make the NBG-417N more secure and to
manage the NBG-417N more effectively.
• 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-417N to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the NBG-417N. You
could simply restore your last configuration.

CHAPTER 2
The WPS Button
2.1 Overview
Your NBG-417N supports WiFi Protected Setup (WPS), which is an easy way to set
up a secure wireless network. 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. Each WPS connection works
between two devices. Both devices must support WPS (check each device’s
documentation to make sure).
Depending on the devices you have, you can either press a button (on the device
itself, or in its configuration utility) or enter a PIN (a unique Personal Identification
Number that allows one device to authenticate the other) in each of the two
devices. When WPS is activated on a device, it has two minutes to find another
device that also has WPS activated. Then, the two devices connect and set up a
secure network by themselves.
For more information on using WPS, see Section 6.2 on page 61.

CHAPTER 3
Introducing the Web
Configurator
This chapter describes how to access the NBG-417N Web Configurator and
provides an overview of its screens.
3.1 Web Configurator Overview
The Web Configurator is an HTML-based management interface that allows easy
setup and management of the NBG-417N via Internet browser. Use Internet
Explorer 6.0 and later or Netscape Navigator 7.0 and later versions or Safari 2.0
or 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.
• JavaScripts (enabled by default).
• Java permissions (enabled by default).
Refer to the Troubleshooting chapter to see how to make sure these functions are
allowed in Internet Explorer.
3.2 Accessing the Web Configurator
1 Make sure your NBG-417N hardware is properly connected and prepare your
computer or computer network to connect to the NBG-417N (refer to the Quick
Start Guide).
2 Launch your web browser.

NBG-417N User’s Guide

Chapter 4 Connection Wizard
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-417N (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG-417N does that part of the task. Furthermore, with NAT, all of the
LAN's computers will have Internet access.
Refer to the appendix for more information on PPPoE.

4.4.5 WAN 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 15 Private IP Address Ranges
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
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.
Note: 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.
4.4.6 IP Address and Subnet Mask
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.
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.
48
NBG-417N User’s Guide
Page 49
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-417N, 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-417N 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-417N unless you are instructed to do otherwise.
4.4.7 DNS Server Address Assignment
Use DNS (Domain Name System) to map a domain name to its corresponding IP
address and vice 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-417N can get the DNS server addresses in the following ways.
Chapter 4 Connection Wizard
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, enter them
in the DNS Server fields in the Wizard and/or WAN > Internet Connection
screen.
2 If the ISP did not give you DNS server information, leave the DNS Server fields
set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN >
Internet Connection screen for the ISP to dynamically assign the DNS server IP
addresses.

6.2 Configure Wireless Security Using WPS on both your NBG-417N and Wireless Client
This section gives you an example of how to set up wireless network using WPS.
This example uses the NBG-417N as the AP and NWD210N as the wireless client
which connects to a notebook.
Note: 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 6.2.1 on page 62.This is the easier method.
NBG-417N User’s Guide
61
Page 62
Chapter 6 Tutorials
• PIN Configuration - create a secure wireless network simply by entering a
wireless client's PIN (Personal Identification Number) in the NBG-417N’s
interface. See Section 6.2.2 on page 63. This is the more secure method, since
one device can authenticate the other.
6.2.1 Push Button Configuration (PBC)
1 Make sure that your NBG-417N is turned on and that it is within range of your
computer.
2 Make sure that you have installed the wireless client (this example uses the
NWD210N) driver and utility in your notebook.
3 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS
button (Start or WPS button)
4 Log into NBG-417N’s Web Configurator and press the Push Button button in the
Network > Wireless Client > WPS Station screen.
Note: Your NBG-417N has a WPS button located on its panel, as well as a WPS
button in its configuration utility. Both buttons have exactly the same function;
you can use one or the other.
Note: It doesn’t matter which button is pressed first. You must press the second
button within two minutes of pressing the first one.
The NBG-417N sends the proper configuration settings to the wireless client. This
may take up to two minutes. Then the wireless client is able to communicate with
the NBG-417N securely.

clients. Make sure that your notebook or computer’s wireless adapter supports
one of these standards.
2 Wireless adapters come with software sometimes called a “utility” that you install
on your computer. See your wireless adapter’s User’s Guide for information on
how to do that.

7.2 What You Can Do In the Wireless LAN Screen
•Use the General screen (Section 7.4 on page 75) to enable the Wireless LAN,
enter the SSID and select the wireless security mode.
•Use the MAC Filter screen (Section 7.5 on page 80) to allow or deny wireless
stations based on their MAC addresses from connecting to the NBG-417N.
•Use the Advanced screen (Section 7.6 on page 82) to allow intra-BSS
networking and set the RTS/CTS Threshold.
•Use the QoS screen (Section 7.7 on page 83) to ensure Quality of Service (QoS)
in your wireless network.
•Use the WPS screen (Section 7.8 on page 87) to quickly set up a wireless
network with strong security, without having to configure security settings
manually.
•Use the WPS Station screen (Section 7.9 on page 88) to add a wireless station
using WPS.
•Use the Scheduling screen (Section 7.10 on page 88) to set the times your
wireless LAN is turned on and off.
7.3 What You Should Know About Wireless LAN
Every wireless network must follow these basic guidelines.
• 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.
7.3.1 Wireless Security Overview
The following sections introduce different types of wireless security you can set up
in the wireless network.
7.3.1.1 SSID
72
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area.
You can hide the SSID instead, in which case the AP does not broadcast the SSID.
NBG-417N User’s Guide
Page 73
In addition, you should change the default SSID to something that is difficult to
guess.
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.
7.3.1.2 MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A
MAC address is usually written using twelve hexadecimal characters
example, 00A0C5000002 or 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.
Chapter 7 Wireless LAN
2
; for
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.
7.3.1.3 User Authentication
You can make every user log in to the wireless network before they can use it.
This is called user authentication. However, every wireless client in the wireless
network has to support IEEE 802.1x to do this.
For wireless networks, there are two typical places to store the user names and
passwords for each user.
• In the AP: this feature is called a local user database or a local database.
• In a RADIUS server: this is a server used in businesses more than in homes.
If your AP does not provide a local user database and if you do not have a RADIUS
server, you cannot set up user names and passwords for your users.
Unauthorized devices can still see the information that is sent in the wireless
network, even if they cannot use the wireless network. Furthermore, there are
ways for unauthorized wireless users to get a valid user name and password.
Then, they can use that user name and password to use the wireless network.
1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks.
These kinds of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
NBG-417N User’s Guide
73
Page 74
Chapter 7 Wireless LAN
Local user databases also have an additional limitation that is explained in the
next section.
7.3.1.4 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.
The types of encryption you can choose depend on the type of user
authentication. (See Section 7.3.1.3 on page 73 for information about this.)
Table 22 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
Weakest No Security WPA
Static WEP
WPA-PSK
StrongestWPA2-PSK WPA2
For example, if the wireless network has a RADIUS server, you can choose WPA
or WPA2. 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. For example, suppose the AP does not have a local
user database, and you do not have a RADIUS server. Therefore, there is no user
authentication. Suppose the wireless network has two wireless clients. Device A
only supports WEP, and device B supports WEP and WPA. Therefore, you should
set up Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, 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 original information
pretty quickly.
Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user
database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select WPA2 or WPA2-PSK in your NBG-417N, you can also select an
option (WPA Compatible) to support WPA as well. In this case, if some wireless
clients support WPA and some support WPA2, you should set up WPA2-PSK or
WPA2 (depending on the type of wireless network login) and select the WPA
Compatible option in the NBG-417N.
74
NBG-417N User’s Guide

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.
7.3.1.5 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 6.2 on page 61.

access points must use the same WEP key.
Your NBG-417N allows you to configure up to four 64-bit or 128-bit WEP keys but
only one key can be enabled at any one time.

WAN
8.1 Overview
This chapter discusses the NBG-417N’s WAN screens. Use these screens to
configure your NBG-417N 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.
Figure 49 LAN and WAN

ISP information and set how the computer acquires its IP, DNS and WAN MAC
addresses.

Chapter 8 WAN
8.3 What You Need To Know About WAN
The information in this section can help you configure the screens for your WAN
connection, as well as enable/disable some advanced features of your NBG-417N.
8.3.1 Configuring Your Internet Connection
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 PPTP
(Point-to-Point Tunneling Protocol), 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 NBG-417N, which makes it accessible
from an outside network. It is used by the NBG-417N to communicate with other
devices in other networks. It can be static (fixed) or dynamically assigned by the
ISP each time the NBG-417N 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).
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP
address and vice 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-417N 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.
92
2 If your ISP dynamically assigns the DNS server IP addresses (along with the NBG-
417N’s WAN IP address), set the DNS server fields to get the DNS server address
from the ISP.
NBG-417N User’s Guide
Page 93
WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by
either using the factory default or cloning the MAC address from a computer on
your LAN. Choose Factory Default to select the factory assigned default MAC
Address.
Otherwise, click Clone the computer's MAC address - IP Address and enter
the IP address of the computer on the LAN whose MAC you are cloning. Once it is
successfully configured, the address will be copied to configuration file. It is
recommended that you clone the MAC address prior to hooking up the WAN Port.
8.3.2 Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just 1.
Chapter 8 WAN
Figure 50 Multicast Example
A
B
C
D
In the multicast example above, systems A and D comprise one multicast group.
In multicasting, the server only needs to send one data stream and this is
delivered to systems A and D.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group - it is not used to carry user data. The
NBG-417N supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-
v2).
At start up, the NBG-417N queries all directly connected networks to gather group
membership. After that, the NBG-417N periodically updates this information. IP
multicasting can be enabled/disabled on the NBG-417N LAN and/or WAN
interfaces in the Web Configurator (LAN; WAN). Select None to disable IP
multicasting on these interfaces.

Chapter 8 WAN
8.3.3 NetBIOS over TCP/IP
NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets
that enable a computer to connect to and communicate with a LAN. For some dialup services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.
However it may sometimes be necessary to allow NetBIOS packets to pass
through to the WAN in order to find a computer on the WAN.
8.3.4 Auto-Bridge
In the rear panel of your NBG-417N, you can see four LAN ports (1 to 4) and one
WAN port. The WAN port is for your Internet access connection, and the LAN ports
are for your network devices. The WAN port has a different IP address from the
LAN ports.
When you enable auto-bridging in your NBG-417N, all five ports (4 LAN ports and
the WAN port) share the same IP address as shown in the figure below.
Figure 51 Autobridging Example
IP Address: 192.168.1.20
This might happen if you put the NBG-417N behind a NAT router that assigns it
this IP address. When the NBG-417N is in auto-bridge mode, the NBG-417N acts
as an AP and all the interfaces (LAN, WAN and WLAN) are bridged. In this mode,
your NAT, DHCP server and firewall on the NBG-417N are not available. You do not
have to reconfigure them if you return to router mode.
Auto-bridging only works under the following conditions:
• The WAN IP must be 192.168.x.y (where x and y must be from zero to nine). If
the LAN IP address and the WAN IP address are in the same subnet but x or y
is greater than nine, the device operates in router mode (with firewall
available).
• The device must be in Router Mode (see Chapter 21 on page 181 for more
information) for auto-bridging to become active.

8.4.2 PPPoE Encapsulation
The NBG-417N supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is
an IETF standard (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).

NBG-417N User’s Guide

Chapter 8 WAN
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-417N (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG-417N does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.
This screen displays when you select PPPoE encapsulation.

8.4.3 PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure
transfer 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.
