CHAPTER 1
Introduction
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.
There are two USB 2.0 ports on the side panel of your NBG6815. You can connect USB (version 2.0
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6815
automatically detects the USB devices.
1.2 Applications
Your can have the following networks with the NBG6815:
•Wired. You can connect network devices via the Ethernet ports of the NBG6815 so that they can
communicate with each other and access the Internet.
•Wireless. 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 WPS-
compatible device.
•WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG6815
Use any of the following methods to manage the NBG6815.
• 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 NBG6815.
• Web Configurator. This is recommended for everyday management of the NBG6815 using a
(supported) web browser.
Chapter 1 Introduction
NBG6815 User’s Guide

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
1Make sure the power LED is on.
2Press the RESET button for one to four seconds to restart/reboot the NBG6815.
3Press 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 side panel of the NBG6815 to activate WPS in order to
quickly set up a wireless network with strong security.

1Make sure the power LED is on (not blinking).
2Press the WPS button for more than three seconds and release it. Press the WPS button on another
WPS-enabled device within range of the NBG6815.
Note: You must activate WPS in the NBG6815 and in another wireless device within two
minutes of each other.
For more information on using WPS, see Section 8.2 on page 48.

CHAPTER 2
Introducing the Web Configurator
2.1 Overview
This chapter describes how to access the NBG6815 Web Configurator and provides an overview of
its screens.
The Web Configurator is an HTML-based management interface that allows easy setup and
management of the NBG6815 via Internet browser. Use a browser that supports HTML5, such as
Internet Explorer 9.0 and later versions, Mozilla Firefox 21 and later versions, Safari 6.0 and later
versions or Google Chrome 26.0 and later versions. The recommended screen resolution is 1024 by
768 pixels.
In order to use the Web Configurator you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in
Windows XP SP (Service Pack) 2.
• JavaScript (enabled by default).
• Java permissions (enabled by default).
Refer to the Troubleshooting chapter (Chapter 16 on page 152) to see how to make sure these
functions are allowed in Internet Explorer.
2.2 Accessing the Web Configurator
1Make sure your NBG6815 hardware is properly connected and prepare your computer or computer
network to connect to the NBG6815 (refer to the Quick Start Guide).

3.3.1 WAN Selection Type: Automatic - DHCP
Select the Automatic - DHCP 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
Tutorials
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.
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.
•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a
button. See Section 8.2.1 on page 48. 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 NBG6815’s interface. See Section 8.2.2 on page 49. This
is the more secure method, since one device can authenticate the other.
8.2.1 Push Button Configuration (PBC)
1Make sure that your NBG6815 is turned on. Make sure the WIFI button (at the back panel of the
NBG6815) is pushed in, and that the device is placed within range of your notebook.
2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or
WPS button)
4Log into NBG6815’s Web Configurator and press the Push Button in the Expert > Wireless >
WPS screen.
Chapter 8 Tutorials
NBG6815 User’s Guide

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.
1Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method
to get a PIN number.

8.3.1 Configure Your Notebook
Note: In this example, we use the ZyXEL NWD6505 wireless adapter as the wireless
client and use the Windows built-in utility (Windows Zero Configuration (WZC)) to
connect to the wireless netwok.
1The NBG6815 supports IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n and IEEE
802.11ac wireless clients. Make sure that your notebook or computer’s wireless adapter supports
one of these standards.
2Wireless adapters come with software sometimes called a “utility” that you install on your
computer. See your wireless adapter’s User’s Guide for information on how to do that.
3After you’ve installed the driver and attached the NWD6505 to your computer’s USB port, right-
click the Wireless Network Connection icon in your computer’s system tray, select and click

7Check the status of your wireless connection in the screen below.
8If the wireless client keeps trying to connect to or acquiring an IP address from the NBG6815, make
sure you entered the correct security key.
If the connection has limited or no connectivity, make sure the DHCP server is enabled on the
NBG6815.
If your connection is successful, open your Internet browser and enter http://www.zyxel.com or the
URL of any other web site in the address bar. If you are able to access the web site, your wireless
connection is successfully configured.
8.4 Using Guest SSIDs on the NBG6815
You can configure more than one guest SSID on a NBG6815. See Section 11.4 on page 94.
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).

WAN
10.1 Overview
This chapter discusses the NBG6815’s WAN 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.
Figure 45 LAN and WAN
10.2 What You Can Do
•Use the Internet Connection screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (Section 10.4 on page 70).
•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 Dynamic DNS screen to change your NBG6815’s DDNS settings (Section 10.6 on page
82).
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 NBG6815.
Chapter 10 WAN
NBG6815 User’s Guide
68
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.
1The 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.
2If 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 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.
Chapter 10 WAN
NBG6815 User’s Guide

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.
Figure 46 Multicast Example
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
(IGMP-v1) and IGMP version 2 (IGMP-v2).
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 (WAN). Select None to disable IP
multicasting on these interfaces.
Auto-IP Change
When the NBG6815 gets a WAN IP address or a DNS server IP address which is in the same subnet
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.

Auto-IP-Change only works under the following conditions:
• The NBG6815 must be in Router Mode (see Section 15.12 on page 149 for more information)
for Auto-IP-Change to become active.
• The NBG6815 is set to receive a dynamic WAN 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 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.
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.

CHAPTER 11
Wireless LAN
11.1 Overview
This chapter discusses how to configure the wireless network settings in your NBG6815. The
NBG6815 is able to function both 2.4GHz and 5GHz network at the same time. You can have
different wireless and wireless security settings for 2.4GHz and 5GHz wireless LANs. Click Expert
Mode > Wireless to configure wireless LAN 2.4G or wireless LAN 5G.
See the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 53 Example of a Wireless Network
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.
Chapter 11 Wireless LAN
NBG6815 User’s Guide
85
11.1.1 What You Can Do
•Use the Wireless screen to enable or disable the 2.4GHz or 5GHz wireless LAN, set up wireless
security between the NBG6815 and the wireless clients, and make other basic configuration
changes (Section 11.2 on page 89).
•Use the Guest Wireless screen to set up multiple wireless networks on your NBG6815 (Section
11.4 on page 94).
•Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the NBG6815 (Section 11.5 on page 97).
•Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section
11.6 on page 98).
•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 99).
•Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 11.8
on page 101).
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 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 characters2; for 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.
Chapter 11 Wireless LAN
NBG6815 User’s Guide
86
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 86
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.
Table 25 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
Weakest No Security WPA
WPA-PSK
Strongest WPA2-PSK WPA2
Chapter 11 Wireless LAN
NBG6815 User’s Guide
87
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, 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 WPA, and device B supports WPA and WPA2.
Therefore, you should set up WPA or WPA-PSK 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 NBG6815, you can also select an option (WPA/
WPA-PSK Compatible) to support WPA/WPA-PSK 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/WPA-PSK Compatible 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.

LAN
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.
Figure 66 LAN Example
The LAN screens can help you configure a manage IP address, and partition your physical network
into logical networks.
12.2 What You Can Do
•Use the LAN IP screen to configure the IPv4 and IPv6 addresses for your NBG6815 on the LAN
(Section 12.4 on page 104).
•Use the Static DHCP screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 12.5 on page 105).
•Use the IPv6 LAN screen to configure the IPv6 address for your NBG6815 on the LAN (Section
12.6 on page 106).
12.3 What You Need To Know
The actual physical connection determines whether the NBG6815 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.
Chapter 12 LAN
NBG6815 User’s Guide

Applications
13.1 Overview
This chapter shows you how to configure parental control, bandwidth management, USB media
sharing, UPnP and file sharing.
13.1.1 What You Can Do
•Use the Parental Control screens to enable parental control, configure the parental control
rules and schedules, and send e-mail notifications. (Section 13.2 on page 110).
•Use the Bandwidth Management screen to configure bandwidth management and the device
priority (Section 13.3 on page 116).
•Use the USB Media Sharing screen to use the NBG6815 as a media server and allow DLNA-
compliant devices to play media files stored in the attached USB device (Section 13.4 on page
119).
•Use the UPnP screen to enable UPnP on your NBG6815 (Section 13.5 on page 121).
•Use the File Sharing screen to allow file sharing via the NBG6815 using Windows Explorer, the
workgroup name or FTP (Section 13.6 on page 122).
•Use the One Connect screen to enable or disable Wi-Fi auto-configuration (Section 13.7 on page
129).
13.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Keyword Blocking URL Checking
The NBG6815 checks the URL’s domain name (or IP address) and file path separately when
performing keyword blocking.
The URL’s domain name or IP address is the characters that come before the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is
www.zyxel.com.tw.
The file path is the characters that come after the first slash in the URL. For example, with the URL
www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.
Since the NBG6815 checks the URL’s domain name (or IP address) and file path separately, it will
not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/
pressroom.php, the NBG6815 would find “tw” in the domain name (www.zyxel.com.tw). It would
also find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.

DLNA
The Digital Living Network Alliance (DLNA) is a group of personal computer and electronics
companies that works to make products compatible in a home network. DLNA clients play files
stored on DLNA servers. The NBG6815 can function as a DLNA-compliant media server and stream
files to DLNA-compliant media clients without any configuration.
Workgroup name
This is the name given to a set of computers that are connected on a network and share resources
such as a printer or files. Windows automatically assigns the workgroup name when you set up a
network.
File Systems
A file system is a way of storing and organizing files on your hard drive and storage device. Often
different operating systems such as Windows or Linux have different file systems. The file-sharing
feature on your NBG6815 supports New Technology File System (NTFS), File Allocation Table (FAT)
and FAT32 file systems.
Windows/CIFS
Common Internet File System (CIFS) is a standard protocol supported by most operating systems
in order to share files across the network.
CIFS runs over TCP/IP but uses the SMB (Server Message Block) protocol found in Microsoft
Windows for file and printer access; therefore, CIFS will allow all applications, not just Web
browsers, to open and share files across the Internet.
The NBG6815 uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS
compatible computers can access the USB file storage devices connected to the NBG6815. CIFS
protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to
your systems specifications for CIFS compatibility).
Samba
SMB is a client-server protocol used by Microsoft Windows systems for sharing files, printers, and
so on.
Samba is a free SMB server that runs on most Unix and Unix-like systems. It provides an
implementation of an SMB client and server for use with non-Microsoft operating systems.
File Transfer Protocol
This is a method of transferring data from one computer to another over a network such as the
Internet.

Universal Plug-and-Play (UPnP)
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP
compatible device installed on your network will appear as a separate icon. Selecting the icon of a
UPnP device will allow you to access the information and properties of that device.
13.1.3 Before You Begin
Make sure the NBG6815 is connected to your network and turned on.
1Connect the USB device to one of the NBG6815’s USB ports.
2The NBG6815 detects the USB device and makes its contents available for browsing. If you are
connecting a USB hard drive that comes with an external power supply, make sure it is connected
to an appropriate power source that is on.
Note: If your USB device cannot be detected by the NBG6815, see the troubleshooting
for suggestions.
13.2 Parental Control
Parental Control allows you to block specific URLs. You can also define time periods and days during
which the NBG6815 performs parental control on a specific user.

13.3 Bandwidth Management
The NBG6815 supports the new StreamBoost technology, introduced by Qualcomm, to redistribute
traffic over the NBG6815 for the best possible performance in a home network.
Streamboost is smart Quality of Service (QoS). Streamboost detects traffic flow and applies traffic
shaping policies automatically. It gives each device and each application priority and provides the
exact amount of bandwidth they need at a given time. This helps free up bandwidth for other
applications or connected devices. If there is not enough bandwidth for optimal performance,
Streamboost makes sure the application or device has the minimum acceptable bandwidth which is
determined according to StreamBoost’s cloud-based database.
Real-time application traffic (such as on-line games or communications) and video/audio streaming
are given the highest priority. Downloads or torrent files are classified as best effort and placed
lower than general network traffic (general browsing).
In the figure below, the StreamBoost-enabled NBG6815 differentiates incoming traffic flow going
from the LAN device (A) or wireless device (B) to the Internet. It shapes traffic and gives priority
and allocates bandwidth according to traffic types.

13.8 Technical Reference
The following section contains additional technical information about the NBG6815 features
described in this chapter.
Customizing Keyword Blocking URL Checking
You can use commands to set how much of a website’s URL the content filter is to check for
keyword blocking. See the appendices for information on how to access and use the command
interpreter.
Domain Name or IP Address URL Checking
By default, the NBG6815 checks the URL’s domain name or IP address when performing keyword
blocking.
This means that the NBG6815 checks the characters that come before the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, content filtering only searches
for keywords within www.zyxel.com.tw.
Full Path URL Checking
Full path URL checking has the NBG6815 check the characters that come before the last slash in the
URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking
searches for keywords within www.zyxel.com.tw/news/.
Use the ip urlfilter customize actionFlags 6 [disable | enable] command to extend (or
not extend) the keyword blocking search to include the URL's full path.
File Name URL Checking
Filename URL checking has the NBG6815 check all of the characters in the URL.
For example, filename URL checking searches for keywords within the URL www.zyxel.com.tw/
news/pressroom.php.

NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP
network devices can automatically configure network addressing, announce their presence in the
network to other UPnP devices and enable exchange of simple product and service descriptions.
NAT traversal allows the following:
• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the NAT chapter for more information on NAT.
Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configuration may also
be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the NBG6815 allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.

CHAPTER 14
Security
14.1 Overview
Use these screens to enable and configure the firewall that protects your NBG6815 and your LAN
from unwanted or malicious traffic.
Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and
control access between the LAN and WAN. By default the firewall:
• allows traffic that originates from your LAN computers to go to all of the networks.
• blocks traffic that originates on the other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant
Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2).
However other traffic initiated from the WAN is blocked (3 and 4).
Figure 87 Default Firewall Action
14.1.1 What You Can Do
•Use the IPv4 Firewall screen to enable or disable the NBG6815’s IPv4 firewall (Section 14.2 on

About the NBG6815 Firewall
The NBG6815’s firewall feature physically separates the LAN and the WAN and acts as a secure
gateway for all data passing between the networks.
It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when
activated (click the IPv4 Firewall or IPv6 Firewall tab under Security and then click the Enable
Firewall check box). The NBG6815's purpose is to allow a private Local Area Network (LAN) to be
securely connected to the Internet. The NBG6815 can be used to prevent theft, destruction and
modification of data, as well as log events, which may be important to the security of your network.
The NBG6815 is installed between the LAN and a broadband modem connecting to the Internet.
This allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The NBG6815 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically
separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband
(cable or DSL) modem to the Internet.
The LAN (Local Area Network) port attaches to a network of computers, which needs security from
the outside world. These computers will have access to Internet services such as e-mail, FTP and
the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host
is authorized to use a specific service.
Guidelines For Enhancing Security With Your Firewall
1Change the default password via Web Configurator.
2Think about access control before you connect to the network in any way, including attaching a
modem to the port.
3Limit who can access your router.
4Don't enable any local service (such as NTP) that you don't use. Any enabled service could present
a potential security risk. A determined hacker might be able to find creative ways to misuse the
enabled services to access the firewall or the network.
5For local services that are enabled, protect against misuse. Protect by configuring the services to
communicate only with specific peers, and protect by configuring rules to block packets for the
services at specific interfaces.
6Protect against IP spoofing by making sure the firewall is active.
7Keep the firewall in a secured (locked) room.

I don’t know the IP address of my NBG6815.
6The default IP address of the NBG6815 in Router Mode is 192.168.1.1. If the NBG6815 obtains a
WAN IP address in the same subnet as the LAN IP address 192.168.1.1, the default LAN IP address
will be changed to 10.0.0.1 automatically. See Auto-IP Change on page 69 for more information.
The default IP address of the NBG6815 in Access Point Mode is 192.168.1.2.
7If you changed the IP address and have forgotten it, you might get the IP address of the NBG6815
in Router Mode by looking up the IP address of the default gateway for your computer. To do this
in most Windows computers, click Start > Run, enter cmd, and then enter ipconfig. The IP
address of the Default Gateway might be the IP address of the NBG6815 (it depends on the
network), so enter this IP address in your Internet browser.
8If your NBG6815 in Access Point Mode is a DHCP client, you can find your IP address from the
DHCP server. This information is only available from the DHCP server which allocates IP addresses
on your network. Find this information directly from the DHCP server or contact your system
administrator for more information.
9Reset your NBG6815 to change all settings back to their default. This means your current settings
are lost. See Section 16.5 on page 156 in the Troubleshooting for information on resetting your

• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless
devices.
To optimize the speed and quality of your wireless connection, you can:
• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless networks or surrounding
wireless electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the wireless client.
• Reduce the number of wireless clients connecting to the same AP simultaneously, or add
additional APs if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the
wireless client is sending or receiving a lot of information, it may have too many programs open
that use the Internet.
