Tips for Reading User’s Guides On-Screen
When reading a ZyXEL User’s Guide On-Screen, keep the following in mind:
• If you don’t already have the latest version of Adobe Reader, you can download it from http://
www.adobe.com.
• Use the PDF’s bookmarks to quickly navigate to the areas that interest you. Adobe Reader’s
bookmarks pane opens by default in all ZyXEL User’s Guide PDFs.
• If you know the page number or know vaguely which page-range you want to view, you can
enter a number in the toolbar in Reader, then press [ENTER] to jump directly to that page.
• Type [CTRL]+[F] to open the Adobe Reader search utility and enter a word or 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.
• Embedded hyperlinks are actually cross-references to related text. Click them to jump to the
corresponding section of the User’s Guide PDF.

1.1 Overview
This chapter introduces the main features and applications of the NBG5715.
The NBG5715 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 802.11a/b/
g/n compatible devices. The NBG5715 is able to function both 2.4G and 5G network at the same
time.
A range of services such as a firewall and content filtering are also available for secure Internet
computing. You can use media bandwidth management to efficiently manage traffic on your
network. Bandwidth management features allow you to prioritize time-sensitive or highly important
applications such as Voice over the Internet (VoIP).
There are two USB 2.0 ports on the side panel of your NBG5715. You can connect USB (version 2.0
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG5715
automatically detects the USB devices.
CHAPTER 1
Introduction
T wo USB eject buttons are located above the USB ports. Push the eject button of the corresponding
USB port for 2 seconds. Make sure the USB LED is off before removing your USB device. This will
remove your USB device safely, preventing file or data loss if it is being transmitted through the
USB device.

1.3 Ways to Manage the NBG5715
Use any of the following methods to manage the NBG5715.
• 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 NBG5715.
• Web Configurator. This is recommended for everyday management of the NBG5715 using a
(supported) web browser.
1.4 Good Habits for Managing the NBG5715
Do the following things regularly to make the NBG5715 more secure and to manage the NBG5715
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.
22
NBG5715 User’s Guide
• 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 NBG5715 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG5715.
You could simply restore your last configuration.
1.5 LEDs
Look at the LED lights on the front panel to determine the status of the NBG5715. Use the LED
button at the side panel of the device to turn the LED lights on or off. If you have already pushed
the LED button to the ON position but none of the LEDS are on, make sure the NBG5715 is
receiving power and the power is turned on.
Note: The Power LED will be on even if you push the LED button to the OFF position.

NBG5715 User’s Guide
2.1 Overview
Your NBG5715 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.

This chapter provides tutorials for setting up your NBG5715.
• Set Up a Wireless Network with WPS
• Configure Wireless Security without WPS
9.2 Set Up a Wireless Network with WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the NBG5715 as the AP and NWD210N as the wireless client which connects to a notebook.
Wireless LAN 2.4G is used as the wireless mode in this example.
Tutorials
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 9.2.1 on page 61.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 NBG5715’s interface. See Section 9.2.2 on page 63 . This
is the more secure method, since one device can authenticate the other.
9.2.1 Push Button Configuration (PBC)
1 Make sure that your NBG5715 is turned on. The wireless LAN is enabled by default. Check if WLAN
2.4G LED is on. If not, you can enable wireless LAN by pressing the WLAN On/Off button on the
device’s side panel or in the Network > Wireless LAN 2.4G screen. Make sure that the device is
placed 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).

10.1 Overview
This chapter discusses the NBG5715’s WAN screens. Use these screens to configure your NBG5715
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.

IP, DNS and WAN MAC addresses (Section 10.4 on page 73).
•Use the Advanced screen to enable multicasting (Section 10.5 on page 77).
10.3 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 NBG5715.
NBG5715 User’s Guide 71
Chapter 10 WAN
10.3.1 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 NBG5715, which makes it accessible from an outside
network. It is used by the NBG5715 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG5715 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 NBG5715 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 NBG5715’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by either using the

10.3.2 Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipien t)
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.
Figure 37 Multicast Example
Chapter 10 WAN
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-laye r protocol used to establish membership
in a multicast group - it is not used to carry user data. The NBG5715 supports both IGMP version 1
(IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the NBG5715 queries all directly connected networks to gather group membership.
After that, the NBG5715 periodically updates this information. IP multicasting can be enabled/
disabled on the NBG5715 LAN and/or WAN interfaces in the Web Configurator (LAN; WAN). Select
None to disable IP multicasting on these interfaces.

10.4.2 PPPoE Encapsulation
The NBG5715 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).
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.
Chapter 10 WAN
By implementing PPPoE directly on the NBG5715 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG5715 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.

11.1 Overview
This chapter discusses how to configure the wireless network settings in your NBG5715. The
NBG5715 is able to function both 2.4G and 5G network at the same time. You can have different
wireless settings for 2.4G and 5G. Click Configuration > Network > Wireless LAN 2.4G or
Wireless LAN 5G to configure to do so.
See the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 41 Example of a Wireless Network
CHAPTER 11
Wireless LAN
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 NBG5715 is the AP.
11.1.1 What You Can Do in this Chapter
•Use the General screen to enable or disable wireless LAN, configure SSID, operating channel,
and wireless security (Section 11.2 on page 82).
•Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the NBG5715 (Section 11.4 on page 88).
NBG5715 User’s Guide 79
Chapter 11 Wireless LAN
•Use the Advanced screen to allow intra-BSS networking and set the R TS/CTS Threshold (Section
11.5 on page 90).
•Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 11.6 on
page 90).
•Use the WPS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 11.7 on page 91).
•Use the WPS Station screen to add a wireless station using WPS (Section 11.8 on page 92).
•Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 11.9
on page 93).
11.1.2 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.
Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless
network.
SSID
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.
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.
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
00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s
Guide or other documentation.
2
; for example, 00A0C5000002 or
80
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.
NBG5715 User’s Guide
Chapter 11 Wireless LAN
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.
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.
Local user databases also have an additional limitation that is explained in the next section.
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 page 81
for information about this.)
Table 26 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
Weakest No Security WPA
Static WEP
WPA-PSK
Strongest WPA2-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.
NBG5715 User’s Guide
81
Chapter 11 Wireless LAN
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 NBG5715, 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 NBG5715.
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.
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 9.2 on page 61.
WDS
Wireless Distribution System or WDS security is used between bridged APs. It is independent of the
security between the wired networks and their respective APs. If you do not enable WDS security,
traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same
pre-shared key.
11.2 The General Wireless LAN Screen
Use this screen to configure the SSIDs of the wireless LAN.
Note: If you are configuring the NBG5715 from a computer connected to the wireless LAN
and you change the NBG5715’s SSID, channel or security settings, you will lose
your wireless connection when you press Apply to confirm. You must then change
the wireless settings of your computer to match the NBG5715’s new settings.

12.1 Overview
This chapter describes how to configure LAN settings.
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.
Figure 53 LAN Example
CHAPTER 12
LAN
The LAN screens can help you manage IP addresses.
12.2 What You Can Do in this Chapter
•Use the IP screen to change the IP address for your NBG5715 (Section 12.4 on page 97).
•Use the IP Alias screen to have the NBG5715 apply IP alias to create LAN subnets (Section 12.5
on page 97).
NBG5715 User’s Guide 95
Chapter 12 LAN
12.3 What You Need To Know
The actual physical connection determines whether the NBG5715 ports are LAN or WAN ports.
There are two separate IP networks, one inside the LAN network and the other outside the WAN
network as shown next.
Figure 54 LAN and WAN IP Addresses
The LAN parameters of the NBG5715 are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS
server address(es), read the embedded Web Configurator help regarding what fields need to be
configured.
12.3.1 IP Pool Setup
The NBG5715 is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the NBG5715 itself) in the
lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for
mail, FTP, TFTP, web, etc., that you may have.
12.3.2 LAN TCP/IP
The NBG5715 has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.

12.5 The IP Alias Screen
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The NBG5715 supports three logical LAN interfaces via its single physical
Ethernet interface with the NBG5715 itself as the gateway for each LAN network.
To change your NBG5715’s IP alias settings, click Network > LAN > IP Alias. The screen appears
as shown.

CHAPTER 13
13.1 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 NBG5715’s LAN as a
DHCP server or disable it. When configured as a server, the NBG5715 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.
13.1.1 What You Can Do in this Chapter
•Use the General screen to enable the DHCP server (Section 13.2 on page 99).
•Use the Advanced screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 13.3 on page 100).
•Use the Client List screen to view the current DHCP client information (Section 13.4 on page
101).
DHCP Server
13.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
MAC Addresses
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. Find out the MAC addresses of your network devices if you intend to add them
to the DHCP Client List screen.
13.2 The DHCP Server General Screen
Use this screen to enable the DHCP server. Click Network > DHCP Server. The following screen
displays.

allows individual clients (computers) to obtain TCP/IP configuration at
startup from a server. Enable the DHCP server unless your ISP instructs you
to do otherwise. Select Disable to stop the NBG5715 acting as a DHCP
server. When configured as a server, the NBG5715 provides TCP/IP
configuration for the clients. If not, DHCP service is disabled and you must
have another DHCP server on your LAN, or else the computers must be
manually configured. When set as a server, fill in the following four fields.
This field specifies the first of the contiguous addresses in the IP address
pool for LAN.
13.3 The DHCP Server Advanced Screen
This screen allows you to assign IP addresses on the LAN to specific individual computers based on
their MAC addresses. You can also use this screen to configure the DNS server information that the
NBG5715 sends to the DHCP clients.
