Introduction
1.1 Overview
This chapter introduces the main features and applications of the NBG6817.
The NBG6817 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 NBG6817 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 ports on the side panel of your NBG6817. One is USB 2.0, and the other is USB
3.0. You can connect USB memory sticks, USB hard drives, or USB devices for file sharing. The
NBG6817 automatically detects the USB devices.
1.2 Applications
Your can have the following networks with the NBG6817:
• W ir e d. You can connect network devices via the Ethernet ports of the NBG6817 so that they can
communicate with each other and access the Internet.
• W ir e le ss. Wireless clients can connect to the NBG6817 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 NBG6817
Use any of the following methods to manage the NBG6817.
• 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 NBG6817.
• Web Configurator. This is recommended for everyday management of the NBG6817 using a
(supported) web browser.
NBG6817 User’s Guide

Chapter 1 Introduction
1.4 Good Habits for Managing the NBG6817
Do the following things regularly to make the NBG6817 more secure and to manage the NBG6817
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 NBG6817 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG6817.
You could simply restore your last configuration.
1.5 Resetting the NBG6817
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 NBG6817 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
Make sure the power LED is on.
Press the RESET button for one to four seconds to restart/reboot the NBG6817.
Press the RESET button for longer than five seconds to set the NBG6817 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG6817 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 rear panel of the NBG6817 to activate WPS in order to quickly
set up a wireless network with strong security.
NBG6817 User’s Guide

Chapter 1 Introduction
Make sure the power LED is on (not blinking).
Press the WPS button for more than three seconds and release it. Press the WPS button on another
WPS-enabled device within range of the NBG6817.
Note: You must activate WPS in the NBG6817 and in another wireless device within two
minutes of each other.
For more information on using WPS, see Section 8.2 on page 49.

Introducing the Web Configurator
2.1 Overview
This chapter describes how to access the NBG6817 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 NBG6817 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 7.

Configure the Internet type settings on your NBG6817 in the first part. The following screen
depends on your Internet connection type. Enter the details provided by your Internet Service
Provider (ISP) in the fields (if any).
Check with your ISP to make sure you use the correct type. This wizard screen varies according to
the connection type that you select.

3.3.1 WAN Selection Type: Automatic - DHCP
Select the Aut om a t ic - D H CP option if your ISP did not assign you a fixed IP address.
Figure 10 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 NBG6817 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6817 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.

8.1 Overview
This chapter provides tutorials for setting up your NBG6817.
• Set Up a Wireless Network Using WPS
• Connect to NBG6817 Wireless Network without WPS
• Using Guest SSIDs on the NBG6817
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 NBG6817 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
).
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 Bu t t on Configu r a t ion ( PBC) - create a secure wireless network simply by pressing a
button. See Section 8.2.1 on page 49. This is the easier method.
• PI N Con figu r a t ion - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the NBG6817’s interface. See Section 8.2.2 on page 50. This
is the more secure method, since one device can authenticate the other.
8.2.1 Push Button Configuration (PBC)
Make sure that your NBG6817 is turned on. Make sure the W I FI button (at the back panel of the
NBG6817) is pushed in, and that the device is placed within range of your notebook.
Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (St a r t or
W PS button)
Log into NBG6817’s Web Configurator and press the Pu sh Bu t t on in the Ex pe r t > W ir e le ss >
W PS screen.
NBG6817 User’s Guide

Note: Your NBG6817 has a WPS button located on its rear 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 NBG6817 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 NBG6817 securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both NBG6817 and wireless client (the NWD210N in this example).

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.
The NBG6817 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.
Wireless 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.
After you’ve installed the driver and attached the NWD6505 to your computer’s USB port, rightclick the W ir e le ss N e t w or k Conn e ct ion icon in your computer’s system tray, select and click

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 NBG6817
You can configure more than one guest SSID on a NBG6817. See Section 11.4 on page 105.
This allows you to configure multiple independent wireless networks on the NBG6817 as if there
were multiple APs (virtual APs). Each guest SSID has its own wireless security type. That is, each
SSID on the NBG6817 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 NBG6817 (such as
a printer).

WAN
10.1 Overview
This chapter discusses the NBG6817’s W AN screens. Use these screens to configure your NBG6817
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 52 LAN and WAN
10.2 What You Can Do
• Use the I n t e r n e t Con n e ct ion screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (Section 10.4 on page 76).
• Use the N AT > Ge n e r a l screen to enable NAT, set a default server and change your NBG6817’s
port forwarding settings (Section 10.5.1 on page 88).
• Use the N AT > Por t Tr igge r screen to configure your NBG6817’s trigger port settings (Section
10.5.2 on page 90).
• Use the N AT > Pa sst hr ough screen to configure your NBG6817’s ALGs and VPN pass-through
settings (Section 10.5.3 on page 90).
• Use the D yn a m ic D N S screen to change your NBG6817’s DDNS settings (Section 10.6 on page
92).
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 NBG6817.

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 NBG6817, which makes it accessible from an outside
network. It is used by the NBG6817 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG6817 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 NBG6817 can get the DNS server addresses in the following ways.
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.
If your ISP dynamically assigns the DNS server IP addresses (along with the NBG6817’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 or y D e fa ult
to select the factory assigned default MAC Address.
Otherwise, click Clon e t he com pu t e r 's M AC a ddr 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.
NBG6817 User’s Guide

Chapter 10 WAN
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 53 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 NBG6817 supports both IGMP version 1
(I GM P- v1 ) and IGMP version 2 (I GM P- v2 ).
At start up, the NBG6817 queries all directly connected networks to gather group membership.
After that, the NBG6817 periodically updates this information. IP multicasting can be enabled/
disabled on the NBG6817 WAN interface in the Web Configurator (W AN ). Select N one to disable IP
multicasting on these interfaces.
Auto-IP Change
When the NBG6817 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 NBG6817 to change its LAN IP
address to 10.0.0.1 automatically. If the NBG6817’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 NBG6817 switches to use 192.168.1.1
as its LAN IP address.

Auto-IP-Change only works under the following conditions:
• The NBG6817 must be in Rout e r M ode (see Section 15.12 on page 160 for more information)
for Auto-IP-Change to become active.
• The NBG6817 is set to receive a dynamic WAN IP address.

10.4.2 PPPoE Encapsulation
The NBG6817 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 ove r Et he r ne 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 NBG6817 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6817 does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

Wireless LAN
11.1 Overview
This chapter discusses how to configure the wireless network settings in your NBG6817. The
NBG6817 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 Ex pe r t
M ode > W ir e le ss to configure w ir e le ss LAN 2 .4 G or w ir e le ss LAN 5 G.
See the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 62 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 NBG6817 is the AP.
NBG6817 User’s Guide
94
Chapter 11 Wireless LAN
11.1.1 What You Can Do
• Use the W ir e le ss screen to enable or disable the 2.4GHz or 5GHz wireless LAN, set up wireless
security between the NBG6817 and the wireless clients, and make other basic configuration
changes (Section 11.2 on page 99).
• Use the Gue st W ir e le ss screen to set up multiple wireless networks on your NBG6817 (Section
11.4 on page 105).
• Use the M AC Filt e r screen to allow or deny wireless stations based on their MAC addresses from
connecting to the NBG6817 (Section 11.5 on page 108).
• Use the Adva nce d screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section
11.6 on page 109).
• Use the W PS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 11.7 on page 110).
• Use the Sche duling screen to set the times your wireless LAN is turned on and off (Section 11.8
on page 112).
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.
NBG6817 User’s Guide
95
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 96
for information about this.)

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.

Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
NBG6817 User’s Guide
96
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 PA2 - 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 W PA or W PA- PSK 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 NBG6817, you can also select an option (W PA/
W PA- 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 PA2 - PSK or W PA2 (depending on the
type of wireless network login) and select the W PA/W PA- PSK Com pa t ible option in the
NBG6817.
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
NBG6817 (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

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 75 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 I P screen to configure the IPv4 and IPv6 addresses for your NBG6817 on the LAN
(Section 12.4 on page 115).
• Use the St a t ic D H CP screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 12.5 on page 116).
• Use the I Pv6 LAN screen to configure the IPv6 address for your NBG6817 on the LAN (Section
12.6 on page 117).
12.3 What You Need To Know
The actual physical connection determines whether the NBG6817 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.

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 NBG6817 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 NBG6817 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 NBG6817 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 NBG6817 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 NBG6817 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 NBG6817 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 NBG6817. 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.

13.3 Bandwidth Management
The NBG6817 supports the new StreamBoost technology, introduced by Qualcomm, to redistribute
traffic over the NBG6817 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 NBG6817 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.

13.7 ONE Connect Screen
One Connect is a ZyXEL-proprietary feature. It complies with the IEEE 1905.1 standard and allows
auto-detection and auto-configuration.
If your wireless router supports ZyXEL ONE Connect, NBG6817 for example, you can download and
install the ZyXEL ONE Connect App in your mobile device to check the connection status, do speed
test, turn on or turn off the devices in your network, block or allow a device’s access and set up a
guest Wi-Fi network from the mobile device. You can even use the App to access the NBG6817’s
web configurator. The mobile device with the App installed must be connected to the NBG6817
wirelessly.
Note: You have to go to https://mycloud.zyxel.com and pair your device again when you

13.8 Technical Reference
The following section contains additional technical information about the NBG6817 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 NBG6817 checks the URL’s domain name or IP address when performing keyword
blocking.
This means that the NBG6817 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 NBG6817 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 NBG6817 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.

N AT Tr a ve r sa l
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.
Ca u t ion s w it h 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 NBG6817 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.

14.1 Overview
Use these screens to enable and configure the firewall that protects your NBG6817 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).

About the NBG6817 Firewall
The NBG6817’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 I Pv4 Fir e w a ll or I Pv6 Fir e w a ll tab under Se cur it y and then click the Ena ble
Fir e w a ll check box). The NBG6817's purpose is to allow a private Local Area Network (LAN) to be
securely connected to the Internet. The NBG6817 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 NBG6817 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 NBG6817 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
Change the default password via Web Configurator.
Think about access control before you connect to the network in any way, including attaching a
modem to the port.
Limit who can access your router.
Don'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.
For 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.
Protect against IP spoofing by making sure the firewall is active.
Keep the firewall in a secured (locked) room.

in Rou t e r M ode by looking up the IP address of the default gateway for your computer. To do this
in most Windows computers, click St a r t > Run, enter cm d, and then enter ipconfig. The IP
address of the D e fa ult Ga t e w a y might be the IP address of the NBG6817 (it depends on the
network), so enter this IP address in your Internet browser.
If your NBG6817 in Acce ss Poin t M ode 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.
Reset your NBG6817 to change all settings back to their default. This means your current settings
are lost. See Section 16.5 on page 167 in the Tr ou ble shoot ing for information on resetting your
NBG6817.
