phrase. This can help you quickly pinpoint the information you require. You can
also enter text directly into the toolbar in Reader.
• To quickly move around within a page, press the [SPACE] bar. This turns your
cursor into a “hand” with which you can grab the page and move it around
freely on your screen.

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 6.2.1 on page 61.

PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host
44
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.

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
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.

System DNS Server Address Assignment (if applicable)
DNS (Domain Name System) is for mapping 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 NBG-417N uses a
system DNS server (in the order you specify here) to resolve domain names for DDNS
and the time server.

4.4.9 WAN 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.

6.2.1 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).
NBG-417N User’s Guide
61
Chapter 6 Tutorials
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 6.2.1.1 on page 62.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-417N’s
interface. See Section 6.2.1.2 on page 63. This is the more secure method,
since one device can authenticate the other.
6.2.1.1 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.

6.3 Bandwidth Management for your Network
This section shows you how to configure the bandwidth management feature on
the NBG-417N to limit the bandwidth for specific kinds of outgoing traffic. ZyXEL's
bandwidth management feature allows you to specify bandwidth management
rules based on an application or subnet.
Use the Management > Bandwidth MGMT > Advanced screen to configure
bandwidth management for your network.
6.3.1 Configuring Bandwidth Management by Application
For this example, your company’s customer support department wants to
prioritize VoIP, e-mail and MSN Messenger services.
In the Priority Queue table, VoIP and e-mail services are already pre-defined.
However, you still need to add MSN Messenger in the list (refer to Section 6.3.2
on page 69).
68
NBG-417N User’s Guide
Chapter 6 Tutorials
In the following screen, you set the priorities for VoIP and e-mail.
Figure 37 Tutorial: Priority Queue
Click Enable for the VoIP (SIP) service and set priority to High. Do the same for
E-mail. For the rest of the applications, click Enable if you need these services
and set the priority to Low.
Note: You can also leave the Enable field blank for the rest of the applications. In
doing so, the NBG-417N does not apply bandwidth management to these
services.
6.3.2 Configuring Bandwidth Management by Custom Application
Aside from the VOIP and e-mail services, you need to set the priority for MSN
Messenger. To do this, add the service in the Priority Queue table of the
Management > Bandwidth MGMT > Advanced screen.
Figure 38 Tutorial: Adding MSN Messenger to Priority Queue
NBG-417N User’s Guide

Chapter 6 Tutorials
To add the MSN Messenger service in the Priority Queue:
1 Click Enable in one of the fields for additional services.
2 Add MSN as the service name.
3 Set the priority for this to High.
4 For the port, choose TCP from the drop-down menu and enter 1863 in the
Specific Port field.
Your priority table should now have the VoIP, E-mail and MSN Messenger
services priorities set to High.
6.3.3 Configuring Bandwidth Allocation by IP or IP Range
For this example, your company’s 20th anniversary is coming up. You want to use
the multimedia room’s Internet connection to upload some videos to the website.
You also use this room for video conferences, radio broadcasts, live video
streaming, and so on throughout the day. While these media-heavy activities are
going on, you still want to keep uploading the videos in the background. As such,
you want to dedicate the minimum amount of bandwidth for this traffic.
You know the following:
• Multimedia room’s LAN IP range: 192.168.1.1 to 192.168.1.34
• IP Address of the computer uploading through FTP: 192.168.1.34
• Services you want to configure:

7.3 What You Should Know
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.
76
NBG-417N User’s Guide
7.3.1.1 SSID
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.
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.
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
77
Chapter 7 Wireless LAN
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.
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 77 for information about this.)
Table 23 Types of Encryption for Each Type of Authentication
Weakest No Security WPA
Strongest WPA2-PSK WPA2
NO AUTHENTICATION RADIUS SERVER
Static WEP
WPA-PSK
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
78
NBG-417N User’s Guide
WPA2 (depending on the type of wireless network login) and select the WPA
Compatible option in the NBG-417N.
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 6.2.1 on page 61.

LABEL DESCRIPTION
WEP Encryption Select 64-bit WEP or 128-bit WEP to enable data encryption.
Authentication
Method
ASCII/HEX
Keys 1 to 4t
There are two types of WEP authentication namely, Open System and
Shared Key.
Open system is implemented for ease-of-use and when security is not
an issue. The wireless station and the AP or peer computer do not share
a secret key. Thus the wireless stations can associate with any AP or
peer computer and listen to any transmitted data that is not encrypted.
Shared key mode involves a shared secret key to authenticate the
wireless station to the AP or peer computer. This requires you to enable
the wireless LAN security and use same settings on both the wireless
station and the AP or peer computer.
•Select Shared Key to have the NBG-417N authenticate only those
wireless clients that use Shared Key mode and have the correct WEP
key.
•Select Auto to have the NBG-417N allow association with wireless
clients that use Open System mode. Data transfer is encrypted as
long as the wireless client has the correct WEP key for encryption.
The NBG-417N authenticates wireless clients using Shared Key
mode that have the correct WEP key.
The WEP keys are used to encrypt data. Both the NBG-417N and the
wireless stations must use the same WEP key for data transmission.
If you chose 64-bit WEP, then enter any 5 ASCII characters or 10
hexadecimal characters ("0-9", "A-F").
If you chose 128-bit WEP, then enter 13 ASCII characters or 26
hexadecimal characters ("0-9", "A-F").
You must configure all four keys, but only one key can be activated at
any one time. The default key is key 1.

CHAPTER 8
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 56 LAN and WAN
See the chapter about the connection wizard for more information on the fields in
the WAN screens.
8.2 What You Can Do
•Use the Internet Connection screen (Section 8.4 on page 103) to enter your
ISP information and set how the computer acquires its IP, DNS and WAN MAC
addresses.
•Use the Advanced screen (Section 8.5 on page 109) to enable multicasting,
configure Windows networking and bridge.

8.3 What You Need To Know
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.
100
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.
