1.1 Overview
This chapter introduces the main features and applications of the NBG6815.
The NBG6815 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/ac compatible devices. The NBG6815 is able to function both 2.4GHz and 5GHz networks at the
same time.
A range of services such as a firewall and content filtering are also available for secure Internet
computing.
CHAPTER 1
Introduction
There are two
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6815
automatically detects the USB devices.
USB 2.0 ports on the side panel of your NBG6815. You can connect USB (version 2.0
1.2 Applications
Your can have the following networks with the NBG6815:
• W i red. You can connect network devices via the Ethernet ports of the NBG6815 so that they can
communicate with each other and access the Internet.
• W i rele ss. Wireless clients can connect to the NBG6815 to access network resources. You can
use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPScompatible device.
• W AN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG6815

Chapter 1 Introduction
1.4 Good Habits for Managing the NBG6815
Do the following things regularly to make the NBG6815 more secure and to manage the NBG6815
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 NBG6815 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG6815.
You could simply restore your last configuration.
1.5 Resetting the NBG6815
If you forget your password or IP address, or you cannot access the Web Configurator, you will need
to use the RESET button at the back of the NBG6815 to reload the factory-default configuration
file. This means that you will lose all configurations that you had previously saved, the password
will be reset to “1234” and the IP address will be reset to “192.168.1.1”.
1.5.1 How to Use the RESET Button
1 Make sure the power LED is on.
2 Press the RESET button for one to four seconds to restart/reboot the NBG6815.
3 Press the RESET button for longer than five seconds to set the NBG6815 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG6815 supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure
wireless network. WPS is an industry standard specification, defined by the Wi-Fi 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.
You can use the WPS button ( ) on the

3.3.1 WAN Selection Type: Automatic - DHCP
Select the Au t o m a t ic - D HCP option if your ISP did not assign you a fixed IP address.
Figure 9 WAN Selection Type: Automatic - DHCP
3.3.2 WAN Selection 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, 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 NBG6815 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6815 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.

CHAPTER 8
8.1 Overview
This chapter provides tutorials for setting up your NBG6815.
•
Set Up a Wireless Network Using WPS
• Connect to NBG6815 Wireless Network without WPS
• Using Guest SSIDs on the NBG6815
8.2 Set Up a Wireless Network Using WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the NBG6815 as the AP and NWD210N as the wireless client which connects to a notebook.
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 via the web configurator or utility.
This tutorial shows you how to do both.
• Pu sh Bu t t on Conf ig u ration ( PBC) - create a secure wireless network simply by pressing a
button. See
• PI N Con f igu r atio n - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the NBG6815’s interface. See Section 8.2.2 on page 49. This
is the more secure method, since one device can authenticate the other.
Section 8.2.1 on page 48. This is the easier method.
8.2.1 Push Button Configuration (PBC)
1 Make sure that your NBG6815 is turned on. Make sure the W I FI button (at the back panel of the
NBG6815) is pushed in, and that the device is placed within range of your notebook.
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 (St art or
W PS button)
4 Log into NBG6815’s Web Configurator and press the Pu sh Button in the Ex pert > W ire l ess >

Note: Your NBG6815 has a WPS button located on its front 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 NBG6815 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 NBG6815 securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both NBG6815 and wireless client (the NWD210N in this example).
Figure 35 Example WPS Process: PBC Method
8.2.2 PIN Configuration
When you use the PIN configuration method, you need to use both NBG6815’s configuration
interface and the client’s utilities.
1 Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method
to get a PIN number.
2 Enter the PIN number to the PI N field in the Expe r t > W irele ss > W PS screen on the NBG6815.

You can configure more than one guest SSID on a NBG6815. See
This allows you to configure multiple independent wireless networks on the NBG6815 as if there
were multiple APs (virtual APs). Each guest SSID has its own wireless security type. That is, each
SSID on the NBG6815 represents a different access point/wireless network to wireless clients in the
network.
Clients can associate only with the SSIDs for which they have the correct security settings. Clients
using different SSIDs can access the Internet and the wired network behind the NBG6815 (such as
a printer).

10.1 Overview
This chapter discusses the NBG6815’s W AN screens. Use these screens to configure your NBG6815
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.

•Use the I nter n e t Co n nectio n screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (
•Use the NAT screens to enable NAT, set a default server and change your NBG6815’s port
forwarding settings and trigger port settings (Section 10.5 on page 79).
•Use the Dyn a m i c D N S screen to change your NBG6815’s DDNS settings (

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 NBG6815, which makes it accessible from an outside
network. It is used by the NBG6815 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG6815 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 NBG6815 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 NBG6815’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 Fa ct o ry D e fau lt
to select the factory assigned default MAC Address.
Otherwise, click Clo ne t h e com puter' s M AC addr e ss - I P Addr e ss 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.

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.

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 NBG6815 supports both IGMP version 1
(I GM P-v1 ) and IGMP version 2 (I GMP- v 2 ).
At start up, the NBG6815 queries all directly connected networks to gather group membership.
After that, the NBG6815 periodically updates this information. IP multicasting can be enabled/
disabled on the NBG6815 WAN interface in the Web Configurator (W AN ). Select No ne to disable IP
multicasting on these interfaces.
Auto-IP Change
When the NBG6815 gets a WAN IP address or
as the LAN IP address 192.168.1.1, Auto-IP-Change allows the NBG6815 to change its LAN IP
address to 10.0.0.1 automatically. If the NBG6815’s original LAN IP address is 10.0.0.1 and the
WAN IP address is in the same subnet, such as 10.0.0.3, the NBG6815 switches to use 192.168.1.1
as its LAN IP address.

10.4.2 PPPoE Encapsulation
The NBG6815 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 PP P ove r Ethern e t option is for a dial-up connection using
PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example Radius).
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a
function known as dynamic service selection. This enables the service provider to easily create and
offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no
specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the NBG6815 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6815 does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

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 NBG6815 is the AP.

Every wireless network must follow these basic guidelines.
Chapter 11 Wireless LAN
Section
Section 11.5 on page 97).
Section
Section 11.8
• 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 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.
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.
NBG6815 User’s Guide

; for example, 00A0C5000002 or
85
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
for information about this.)

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.
NBG6815 User’s Guide

Chapter 11 Wireless LAN
For example, if the wireless network has a RADIUS server, you can choose W PA or W PA2 . If users
do not log in to the wireless network, you can choose no encryption, W PA- PSK, or W PA 2 - P SK.
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 WPA, and device B supports WPA and WPA2.
Therefore, you should set up W PA or W PA- P SK in the wireless network.
Note: It is recommended that wireless networks use W PA- PSK, W PA, 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 W PA- PSK, W PA 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 W PA2 or W PA2 - PSK in your NBG6815, you can also select an option (W P A/
W P A- PSK Com pa t ible) to support WPA/WPA-PSK as well. In this case, if some wireless clients
support WPA and some support WPA2, you should set up W PA 2 - PSK or W PA2 (depending on the
type of wireless network login) and select the W PA/W PA-PSK Com pa t ib le option in the
NBG6815.
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.
Guest WLAN
Guest WLAN allows you to set up a wireless network where users can access to Internet via the
NBG6815 (Z), but not other networks connected to the Z. In the following figure, a guest user can
access the Internet from the guest wireless network A via Z but not the home or company network
N .
Note: The home or company network N and Guest WLAN network are independent
networks.
Note: Only Router mode supports guest WLAN.

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
