Getting to Know Your NBG
1.1 Overview
This chapter introduces the main features and applications of the NBG.
The NBG upgrades the speed of your existing WiFi network, providing faster network access to mobile
users. Making use of IEEE 802.11AC technology, it not only upgrades your network to the next level but
also eliminates dead spots, while offering backward compatibility 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. 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).
CHAPTER 1
1.2 Applications
Your can create the following networks using the NBG:
• Wired. You can connect network devices via the Ethernet ports of the NBG so that they can
communicate with each other and access the Internet.
• Wireless. WiFi clients can connect to the NBG to access network resources.
• WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG
Use any of the following methods to manage the NBG.
• Web Configurator. This is recommended for everyday management of the NBG using a (supported)
web browser.
• Wireless switch. You can use the built-in switch of the NBG to turn the WiFi function on and off without
opening the Web Configurator.
• WPS (Wi-Fi Protected Setup) button. You can use the WPS button or the WPS section of the Web
Configurator to set up a WiFi network with your NBG.
NBG6515 User’s Guide

Chapter 1 Getting to Know Your NBG
1.4 Good Habits for Managing the NBG
Do the following things regularly to make the NBG more secure and to manage the NBG 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 to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the NBG. You could simply restore your
last configuration.

Blinking The NBG is negotiating a WPS connection with a WiFi client.
Off The wireless LAN is not ready or has failed.
Your NBG supports WiFi Protected Setup (WPS), which is an easy way to set up a secure WiFi network.
WPS is an industry standard specification, defined by the WiFi Alliance.
WPS allows you to quickly set up a WiFi 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 10.3 on page 70.
1.7 Wall Mounting
You may need screw anchors if mounting on a concrete or brick wall.
Table 2 Wall Mounting Information

1 Select a position free of obstructions on a wall strong enough to hold the weight of the
device.
2 Mark two holes on the wall at the appropriate distance apart for the screws.
NBG6515 User’s Guide
15
Chapter 1 Getting to Know Your NBG
Be careful to avoid damaging pipes or cables located inside the wall
when drilling holes for the screws.
3 If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into
the full depth of the holes, then insert the screws into the anchors. Do not insert the screws all
the way in - leave a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the
screws all the way in - leave a gap of about 0.5 cm.
4 Make sure the screws are fastened well enough to hold the weight of the NBG with the
connection cables.
5 Align the holes on the back of the NBG with the screws on the wall. Hang the NBG on the
screws.

LABEL DESCRIPTION
Primary DNS 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 uses a system DNS server (in the order
you specify here) to resolve domain names for DDNS and the time server.
Enter the primary DNS server's IP address in the fields provided.
Secondary DNS Enter the secondary DNS server's IP address in the fields provided.

2.3.3 Connection Type: PPPoE
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, WiFi, 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 (rather than individual computers), the computers on the
LAN do not need PPPoE software installed, since the NBG does that part of the task. Furthermore, with
NAT, all of the LAN's computers will have Internet access.

5.1 Overview
This chapter introduces the different modes available on your NBG. First, the term “mode” refers to two
things in this User’s Guide.
• Web Configurator mode. This refers to the Web Configurator interface you want to use for editing NBG
features.
• Device mode. This is the operating mode of your NBG, or simply how the NBG is being used in the
network.
5.1.1 Web Configurator Modes
This refers to the configuration interface of the Web Configurator, which has two modes:
CHAPTER 5
NBG Modes
• Easy. The Web Configurator shows this mode by default. Refer to Chapter 6 on page 37 for more
information on the screens in this mode. This interface may be sufficient for users who just want to use
the device.
• Expert. Advanced users can change to this mode to customize all the functions of the NBG. Click
Expert Mode after logging into the Web Configurator. The User’s Guide Chapter 3 on page 26 through
Chapter 25 on page 156 discusses the screens in this mode.
5.1.2 Device Modes
This refers to the operating mode of the NBG, which can act as a:
• Router. This is the default device mode of the NBG. Use this mode to connect the local network to
another network, like the Internet. Go to Section 7.3 on page 48 to view the Status screen in this
mode.
• Access Point. Use this mode if you want to extend your network by allowing network devices to
connect to the NBG wirelessly. Go to Section 8.4 on page 56 view the Status screen in this mode.
• Universal Repeater: In this mode, the NBG can be an access point and a WiFi client at the same time.
Use this mode if there is an existing wireless router or access point in your network and you also want
to allow clients to connect to the NBG. Go to Section 9.5 on page 62 to view the Status screen in this
mode.
The menu for changing device modes is available in Expert mode only.
Note: Choose your Device Mode carefully to avoid having to change it later.
When changing to another mode, the IP address of the NBG changes. The running applications and
services of the network devices connected to the NBG can be interrupted.

Universal Repeater Mode
9.1 Overview
In universal repeater mode, your NBG can act as an access point and WiFi client at the same time. The
NBG can connect to an existing network through another access point and also lets WiFi clients connect
to the network through it. This helps you expand WiFi coverage when you have an access point or
wireless router already in your network.
In the example below, the NBG (A) is configured as a universal repeater. It has three clients that want to
connect to the Internet. The NBG wirelessly connects to the available access point (B).
Figure 46 Universal Repeater Mode
CHAPTER 9
After the NBG and the access point connect, the NBG acquires its IP address from the access point. The
clients of the NBG can now surf the Internet.
9.2 What You Can Do
• Use the Status screen to view read-only information about your NBG (Section 9.5 on page 62).
• Use the AP Select screen to choose an access point that you want the NBG to connect to. You should
know the security settings of the target AP (Section 9.6 on page 65).
• Use other Wireless LAN screens to configure the WiFi settings and WiFi security between the WiFi clients
and the NBG.
• Use the LAN screen to set the IP address for your NBG acting as an access point (Section 8.5 on page
59).

10.3 Configuring WiFi Security Using WPS
This section gives you an example of how to set up a WiFi network using WPS. This example uses the NBG
as the AP and a WPS-enabled Android smartphone as the WiFi client.
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 WiFi network simply by pressing a button. See
Section 10.3.1 on page 70.This is the easier method.
• PIN Configuration - create a secure WiFi network simply by entering a WiFi client's PIN (Personal
Identification Number) in the NBG’s interface. See Section 10.3.2 on page 71. This is the more secure
method, since one device can authenticate the other.

11.1 Overview
This chapter discusses how to configure the WiFi network settings in your NBG. See the appendices for
more detailed information about WiFi networks.
The following figure provides an example of a WiFi network.
Figure 60 Example of a WiFi Network
CHAPTER 11
Wireless LAN
The WiFi 2.4G network is the part in the blue circle and WiFi 5G network is the part in the green circle. In
these WiFi networks, devices A, B and C are called WiFi clients. The WiFi clients use the access point (AP)
to interact with other devices (such as the printer) or with the Internet.
11.2 What You Can Do
• Use the General screen (Section 11.4 on page 82) to enable the wireless LAN, enter the SSID and
select the WiFi security mode.
• Use the MAC Filter screen (Section 11.6 on page 87) to allow or deny WiFi stations based on their MAC
addresses from connecting to the NBG.
NBG6515 User’s Guide
79
Chapter 11 Wireless LAN
• Use the Advanced screen (Section 11.7 on page 88) to allow WiFi advanced features, such as intra-
BSS networking and set the RTS/CTS Threshold.
• Use the QoS screen (Section 11.8 on page 89) to set priority levels to services, such as e-mail, VoIP,
chat, and so on.
• Use the WPS screen (Section 11.9 on page 90) to quickly set up a WiFi network with strong security,
without having to configure security settings manually.
• Use the WPS Device screen (Section 11.10 on page 91) to add a WiFi device using WPS.
• Use the Scheduling screen (Section 11.11 on page 92) to set the times your wireless LAN is turned on
and off.
• Use the Guest WLAN screen (Section 11.12 on page 93) to configure multiple BSSs on the NBG.
11.3 What You Should Know
Every WiFi network must follow these basic guidelines.
• Every WiFi client in the same WiFi network must use the same SSID.
The SSID is the name of the WiFi network. It stands for Service Set IDentity.
• If two WiFi networks overlap, they should use different channels.
Like radio stations or television channels, each WiFi network uses a specific channel, or frequency, to
send and receive information.
• Every WiFi client in the same WiFi network must use security compatible with the AP.
Security stops unauthorized devices from using the WiFi network. It can also protect the information
that is sent in the WiFi network.
11.3.1 WiFi Security Overview
The following sections introduce different types of WiFi security you can set up in the WiFi network.
11.3.1.1 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 WiFi network.
11.3.1.2 MAC Address Filter
Every WiFi client has a unique identification number, called a MAC address.1 A MAC address is usually
written using twelve hexadecimal characters
the MAC address for each WiFi client, see the appropriate User’s Guide or other documentation.
1. Some wireless devices, such as scanners, can detect WiFi networks but cannot use WiFi 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.
2
; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get
NBG6515 User’s Guide
80
You can use the MAC address filter to tell the AP which WiFi clients are allowed or not allowed to use the
WiFi network. If a WiFi client is allowed to use the WiFi network, it still has to have the correct settings
(SSID, channel, and security). If a WiFi client is not allowed to use the WiFi 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 WiFi network. Furthermore, there
are ways for unauthorized devices to get the MAC address of an authorized WiFi client. Then, they can
use that MAC address to use the WiFi network.
11.3.1.3 Encryption
WiFi networks can use encryption to protect the information that is sent in the WiFi 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.
Table 36 Types of Encryption for Each Type of Authentication
Weakest No Security
Strongest WPA2-PSK
Chapter 11 Wireless LAN
NO AUTHENTICATION
WEP
WPA-PSK
Usually, you should set up the strongest encryption that every WiFi client in the WiFi network supports.
Suppose the WiFi network has two WiFi clients. Device A only supports WEP, and device B supports WEP
and WPA-PSK. Therefore, you should set up WEP in the WiFi network.
Note: It is recommended that WiFi networks use WPA-PSK or stronger encryption. IEEE 802.1x
When you select WPA2-PSK in your NBG, you can also select an option (WPA Compatible) to support
WPA as well. In this case, if some WiFi clients support WPA and some support WPA2, you should set up
WPA2-PSK (depending on the type of WiFi network login) and select the WPA Compatible option in the
NBG.
Many types of encryption use a key to protect the information in the WiFi network. The longer the key,
the stronger the encryption. Every WiFi client in the WiFi network must have the same key.
11.3.1.4 WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a WiFi 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 WiFi
network using WPS in the Section 10.3 on page 70.
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.
11.3.1.5 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
NBG6515 User’s Guide
81
Chapter 11 Wireless LAN
between APs is not encrypted. When WDS security is enabled, both APs must use the same pre-shared
key.
11.4 General Wireless LAN 2.4G/5G General Screen
Use this screen to enable the Wireless LAN 2.4G or 5G, enter the SSID and enable Guest WLAN.
Note: If you are configuring the NBG from a computer connected to the wireless LAN and you
change the NBG’s SSID, channel or security settings, you will lose your WiFi connection
when you press Apply to confirm. You must then change the WiFi settings of your
computer to match the NBG’s new settings.
This screen varies depending on whether you chose Static WEP, WPA-PSK or WPA2-PSK to add security
on the selected WiFi network. The WiFi clients which want to associate to this network must have same
WiFi security settings as the NBG. No Security allows any client to connect to this network without
authentication.
If you enable the WPS function, only No Security, Static WEP, WPA-PSK and WPA2-PSK are available in this

12.1 IPv6 Overview
CHAPTER 12
IPv6
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in
IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
Use the IPv6 screens to configure the IP address for your NBG on the LAN or on the WAN.
12.1.1 What You Can Do in this Chapter
• Use the General screen (Section 12.2 on page 97) to configure the IPv6 connection type.
12.1.2 What You Need to Know
IPv6 Addressing
An 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an
example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be
written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can
only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be
written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.

IP addresses.
Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6
prefix length specifies how many most significant bits (start from the left) in the address compose the
network address. The prefix length is written as “/x” where x is a number. For example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) from the left is the network prefix.
Link-local Address
A link-local address uniquely identifies a device on the local network (the LAN). It is similar to a “private IP
address” in IPv4. You can have the same link-local address on multiple interfaces on a device. A link-
NBG6515 User’s Guide

Chapter 12 IPv6
local unicast address has a predefined prefix of fe80::/10. The link-local unicast address format is as
follows.
Table 48 Link-local Unicast Address Format
1111 1110 10 0 Interface ID
10 bits 54 bits 64 bits
Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into
eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character
(1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters. For example,
FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.
Stateless Autoconfiguration
With stateless autoconfiguration in IPv6, addresses can be uniquely and automatically generated.
Unlike DHCPv6 (Dynamic Host Configuration Protocol version six) which is used in IPv6 stateful
autoconfiguration, the owner and status of addresses don’t need to be maintained by a DHCP server.
Every IPv6 device is able to generate its own and unique IP address automatically when IPv6 is initiated
on its interface. It combines the prefix and the interface ID (generated from its own Ethernet MAC
address) to form a complete IPv6 address.
When IPv6 is enabled on a device, its interface automatically generates a link-local address (beginning
with fe80).
When the NBG’s WAN interface is connected to an ISP with a router and the NBG is set to automatically
obtain an IPv6 network prefix from the router for the interface, it generates another address which
combines its interface ID and global and subnet information advertised from the router. (In IPv6, all
network interfaces can be associated with several addresses.) This is a routable global IP address.
Prefix Delegation
Prefix delegation enables an IPv6 router (the NBG) to use the IPv6 prefix (network address) received
from the ISP (or a connected uplink router) for its LAN. The NBG uses the received IPv6 prefix (for
example, 2001:db2::/48) to generate its LAN IP address. Through sending Router Advertisements (RAs)
regularly by multicast, the router passes the IPv6 prefix information to its LAN hosts. The hosts then can
use the prefix to generate their IPv6 addresses.
IPv6 Router Advertisement
An IPv6 router sends router advertisement messages periodically to advertise its presence and other
parameters to the hosts in the same network.
DHCPv6
The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol that
allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other configuration
information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages using UDP.
Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which is used for identification
when they are exchanging DHCPv6 messages. The DUID is generated from the MAC address, time,

This chapter discusses the NBG’s WAN screens. Use these screens to configure your NBG 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.

Chapter 13 WAN
13.3.1 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), 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, which makes it accessible from an outside network. It is
used by the NBG to communicate with other devices in other networks. It can be static (fixed) or
dynamically assigned by the ISP each time the NBG 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 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’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
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.
