Introduction
1.1 Overview
This chapter introduces the main features and applications of the NBG6716.
The NBG6716 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/
ac/b/g/n compatible devices.
A range of services such as a firewall and content filtering are also available for secure Internet
computing. The NBG6716 also supports the new StreamBoost technology, which is smart Quality of
Service (QoS), to redistribute traffic over the NBG6716 for the best possible performance in a home
network.
There are two USB 2.0 ports on the side panel of your NBG6716. You can connect USB (version 2.0
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6716
automatically detects the USB devices.
Two USB eject buttons are located above the USB ports. Push the eject button of the corresponding
USB port for 2 seconds. Make sure the USB LED is off before removing your USB device. This will
remove your USB device safely, preventing file or data loss if it is being transmitted through the
USB device.

Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB
storage devices (such as memory sticks, USB hard drives) and/or USB devices
(such as USB printers). Other USB products are not guaranteed to function
properly with the NBG6716.

Chapter 1 Introduction
1.1.1 Dual-Band
The NBG6716 is a dual-band AP and able to function both 2.4G and 5G networks at the same time.
You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz
band for time sensitive traffic like high-definition video, music, and gaming.
Figure 2 Dual-Band Application
1.2 Applications
Your can have the following networks using the NBG6716:
• Wired. You can connect network devices via the Ethernet ports of the NBG6716 so that they can
communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the NBG6716 to access network resources. You can
use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPScompatible device.
• WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG6716
Use any of the following methods to manage the NBG6716.
• 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 ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the NBG6716 using a
(supported) web browser.

NBG6716 User’s Guide
Chapter 1 Introduction
1.4 Good Habits for Managing the NBG6716
Do the following things regularly to make the NBG6716 more secure and to manage the NBG6716
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 NBG6716 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG6716.
You could simply restore your last configuration.
1.5 Resetting the NBG6716
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 NBG6716 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 NBG6716.
Press the RESET button for longer than five seconds to set the NBG6716 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG6716 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 front panel of the NBG6716 to activate WPS in order to
quickly set up a wireless network with strong security.

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 NBG6716.
Note: You must activate WPS in the NBG6716 and in another wireless device within two
minutes of each other.
For more information on using WPS, see Section 8.2 on page 57.
1.7 LEDs
Look at the LED lights on the front panel to determine the status of the NBG6716. Use the LED
button at the side panel of the device to turn the LED lights on or off. If you have already pushed
the LED button to the ON position but none of the LEDS are on, make sure the NBG6716 is
receiving power and the power is turned on.
Note: The Power LED will be on even if you push the LED button to the OFF position.
This is for you to determine whether the NBG6716 is powered on.

2.3.2 Connection Type: PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with
a broadband modem (for example DSL, cable, 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).
22
NBG6716 User’s Guide
Chapter 2 Connection Wizard
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 NBG6716 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6716 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.

When you enable this, the NBG6716 gets its IP address from the network’s DHCP
server (for example, your ISP). Users connected to the NBG6716 can now access
the network (i.e., the Internet if the IP address is given by the ISP).
The Web Configurator may no longer be accessible unless you know the IP address
assigned by the DHCP server to the NBG6716. You need to reset the NBG6716 to
be able to access the Web Configurator again (see Section 23.7 on page 171 for
details on how to reset the NBG6716).
Also when you select this, you cannot enter an IP address for your NBG6716 in the
field below.
Static IP Address
Click this if you want to specify the IP address of your NBG6716. Or if your ISP or
network administrator gave you a static IP address to access the network or the
Internet.
IP Address
Type the IP address in dotted decimal notation. The default setting is 192.168.1.2.
If you change the IP address you will have to log in again with the new IP address.
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your
NBG6716 will automatically calculate the subnet mask based on the IP address that
you assign. Unless you are implementing subnetting, use the subnet mask
computed by the NBG6716.
Gateway IP Address
Enter a Gateway IP Address (if your ISP or network administrator gave you one)
in this field.
DNS Assignment
First DNS Server
Second DNS Server
Third DNS Server
Select Obtained From ISP if your ISP dynamically assigns DNS server information
(and the NBG6716's WAN IP address). The field to the right displays the (readonly) DNS server IP address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field to the right. If you chose User-Defined, but leave
the IP address set to 0.0.0.0, User-Defined changes to None after you click
Apply. If you set a second choice to User-Defined, and enter the same IP
address, the second User-Defined changes to None after you click Apply.
Select None if you do not want to configure DNS servers. If you do not configure a
DNS server, you must know the IP address of a computer in order to access it.

8.1 Overview
This chapter provides tutorials for setting up your NBG6716.
• Set Up a Wireless Network with WPS
• Configure Wireless Security without WPS
• Using Multiple SSIDs on the NBG6716
8.2 Set Up a Wireless Network with WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the NBG6716 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. 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 57.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 NBG6716’s interface. See Section 8.2.2 on page 58. This
is the more secure method, since one device can authenticate the other.
8.2.1 Push Button Configuration (PBC)
Make sure that your NBG6716 is turned on. Make sure the WIFI button (at the side panel of the
NBG6716) 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 (Start or
WPS button)
Log into NBG6716’s Web Configurator and press the Push Button in the Configuration >
Network > Wireless LAN 2.4G > WPS Station screen.
NBG6716 User’s Guide

Chapter 8 Tutorials
Note: Your NBG6716 has a WPS button located on its 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 NBG6716 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 NBG6716 securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both NBG6716 and wireless client (the NWD210N in this example).

Note: We use the ZyXEL NWD2205 wireless adapter utility screens as an example for the
wireless client. The screens may vary for different models.
The NBG6716 supports IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n 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 utility, open it. If you cannot see your utility’s icon on your screen, go to

8.4 Using Multiple SSIDs on the NBG6716
You can configure more than one SSID on a NBG6716. See Section 11.4 on page 97.
This allows you to configure multiple independent wireless networks on the NBG6716 as if there
were multiple APs (virtual APs). Each virtual AP has its own SSID, wireless security type and MAC
filtering settings. That is, each SSID on the NBG6716 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 NBG6716 (such as
a printer).

10.1 Overview
This chapter discusses the NBG6716’s WAN screens. Use these screens to configure your NBG6716
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 48 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 78).
• Use the Advanced screen to enable multicasting, configure Windows networking and bridge
(Section 10.5 on page 82).
10.3 What You Need To Know

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 NBG6716, which makes it accessible from an outside
network. It is used by the NBG6716 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG6716 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 NBG6716 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 NBG6716’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.
NBG6716 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 49 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 NBG6716 supports both IGMP version 1
(IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the NBG6716 queries all directly connected networks to gather group membership.
After that, the NBG6716 periodically updates this information. IP multicasting can be enabled/
disabled on the NBG6716 WAN interface in the Web Configurator (WAN). Select None to disable IP
multicasting on these interfaces.

10.4.2 PPPoE Encapsulation
The NBG6716 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 NBG6716 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6716 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 NBG6716. The
NBG6716 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
Configuration > Network > Wireless LAN 2.4G or Wireless LAN 5G to configure to do so.
See the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 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 NBG6716 is the AP.
NBG6716 User’s Guide
84
Chapter 11 Wireless LAN
11.1.1 What You Can Do
• Use the General screen to turn the wireless connection on or off, set up wireless security
between the NBG6716 and the wireless clients, and make other basic configuration changes
(Section 11.2 on page 89).
• Use the More AP screen to set up multiple wireless networks on your NBG6716 (Section 11.4 on
page 97).
• Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the NBG6716 (Section 11.5 on page 100).
• Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section
11.6 on page 102).
• Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 11.7 on
page 102).
• Use the WPS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 11.8 on page 103).
• Use the WPS Station screen to add a wireless station using WPS (Section 11.9 on page 105).
• Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section
11.10 on page 105).
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.
NBG6716 User’s Guide
85
Chapter 11 Wireless LAN
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.
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.
86
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.

For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users
do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or
WPA2-PSK.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. For example, suppose the AP does not have a local user database, and you do
not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network
has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA.
Therefore, you should set up Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is
still possible for unauthorized devices to figure out the original information pretty
quickly.
Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user
database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select WPA2 or WPA2-PSK in your NBG6716, 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
NBG6716.
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
NBG6716 (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

This displays the channel the NBG6716 is currently using.
Channel Width
Select the wireless channel width used by NBG6716.
A standard 20MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps
(5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to
300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz channel offers
speeds of up to 1.3Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select Auto 20/40
MHz or Auto 20/40/80 MHz to allow the NBG6716 to adjust the channel bandwidth
automatically.
40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless
clients must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting
in a location where the environment hinders the wireless signal.
Select 20 MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.

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 70 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 IP screen to change the IP address for your NBG6716 (Section 12.4 on page 108).
• Use the IP Alias screen to have the NBG6716 apply IP alias to create LAN subnets (Section 12.5
on page 109).
12.3 What You Need To Know
The actual physical connection determines whether the NBG6716 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.
NBG6716 User’s Guide
107
Chapter 12 LAN
Figure 71 LAN and WAN IP Addresses
The LAN parameters of the NBG6716 in router mode are preset in the factory with the following
values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS
server address(es), read the embedded Web Configurator help regarding what fields need to be
configured.
12.3.1 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The NBG6716 supports three logical LAN interfaces via its single physical
Ethernet interface with the NBG6716 itself as the gateway for each LAN network.

DHCP Server
13.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the NBG6716’s LAN as a
DHCP server or disable it. When configured as a server, the NBG6716 provides the TCP/IP
configuration for the clients. If DHCP service is disabled, you must have another DHCP server on
your LAN, or else the computer must be manually configured.
13.1.1 What You Can Do
• Use the General screen to enable the DHCP server (Section 13.2 on page 111).
• Use the Advanced screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 13.3 on page 111).
• Use the Client List screen to view the current DHCP client information (Section 13.4 on page
113).
13.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
LAN TCP/IP
The NBG6716 has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.
IP Pool Setup
The NBG6716 is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the NBG6716 itself) in the
lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for
mail, FTP, TFTP, web, etc., that you may have.
MAC Addresses
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02. Find out the MAC addresses of your network devices if you intend to add them
to the DHCP Client List screen.

NAT
14.1 Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in
a packet. For example, the source address of an outgoing packet, used within one network is
changed to a different IP address known within another network.
The figure below is a simple illustration of a NAT network. You want to assign ports 21-25 to one
FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign
a default server IP address of 192.168.1.35 to a third (C in the example).
You assign the LAN IP addresses to the devices (A to D) connected to your NBG6716. The ISP
assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic
coming from A to D going out to the Internet use the IP address of the NBG6716, which is
192.168.1.1.

This chapter discusses how to configure NAT on the NBG6716.
Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from
the WAN to be forwarded through the NBG6716.
14.1.1 What You Can Do
• Use the General screen to enable NAT (Section 14.2 on page 117).
NBG6716 User’s Guide
115
Chapter 14 NAT
• Use the Port Forwarding screen to set a default server and change your NBG6716’s port
forwarding settings to forward incoming service requests to the server(s) on your local network
(Section 14.3 on page 118).
• Use the Port Trigger screen to change your NBG6716’s trigger port settings (Section 14.5.3 on
page 123).
14.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Inside/Outside
This denotes where a host is located relative to the NBG6716, for example, the computers of your
subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Global/Local
This denotes the IP address of a host in a packet as the packet traverses a router, for example, the
local address refers to the IP address of a host when the packet is in the local network, while the
global address refers to the IP address of the host when the same packet is traveling in the WAN
side.
Note: Inside/outside refers to the location of a host, while global/local refers to the IP
address of a host used in a packet.
An inside local address (ILA) is the IP address of an inside host in a packet when the packet is still
in the local network, while an inside global address (IGA) is the IP address of the same inside host
when the packet is on the WAN side. The following table summarizes this information.
Table 49 NAT Definitions
ITEM
DESCRIPTION
Inside
This refers to the host on the LAN.
Outside
This refers to the host on the WAN.
Local
This refers to the packet address (source or destination) as the packet travels on the LAN.
Global
This refers to the packet address (source or destination) as the packet travels on the WAN.
Note: NAT never changes the IP address (either local or global) of an outside host.
What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber
(the inside local address) to another (the inside global address) before forwarding the packet to the
WAN side. When the response comes back, NAT translates the destination address (the inside
global address) back to the inside local address before forwarding it to the original inside host. Note
that the IP address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP.
In addition, you can designate servers, for example, a web server and a telnet server, on your local
116

network and make them accessible to the outside world. If you do not define any servers , NAT
offers the additional benefit of firewall protection. With no servers defined, your NBG6716 filters out
all incoming inquiries, thus preventing intruders from probing your network. For more information
on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
How NAT Works
Each packet has two addresses – a source address and a destination address. For outgoing packets,
the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global
Address) is the source address on the WAN. For incoming packets, the ILA is the destination
address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local)
IP addresses to globally unique ones required for communication with hosts on other networks. It
replaces the original IP source address in each packet and then forwards it to the Internet. The
NBG6716 keeps track of the original addresses and port numbers so incoming reply packets can
have their original values restored. The following figure illustrates this.

and the local IP address of the desired server. The port number identifies a service; for example,
web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or
where one server can support more than one service (for example both FTP and web service), it
might be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.
Note: Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
Port forwarding allows you to define the local servers to which the incoming services will be
forwarded. To change your NBG6716’s port forwarding settings, click Network > NAT > Port
Forwarding. The screen appears as shown.
Note: If you do not assign a Default Server, the NBG6716 discards all packets received
for ports that are not specified in this screen or remote management.

14.5 Technical Reference
The following section contains additional technical information about the NBG6716 features
described in this chapter.
14.5.1 NATPort Forwarding: Services and Port Numbers
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP,
that you can make accessible to the outside world even though NAT makes your whole inside
network appear as a single machine to the outside world.
Use the Port Forwarding screen to forward incoming service requests to the server(s) on your
local network. You may enter a single port number or a range of port numbers to be forwarded, and
the local IP address of the desired server. The port number identifies a service; for example, web
service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one
server can support more than one service (for example both FTP and web service), it might be
better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.
Note: Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
14.5.2 NAT Port Forwarding Example
Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example),
port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a
third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address.
The NAT network appears as a single host on the Internet.

Chapter 14 NAT
14.5.3 Trigger Port Forwarding
Some services use a dedicated range of ports on the client side and a dedicated range of ports on
the server side. With regular port forwarding you set a forwarding port in NAT to forward a service
(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN).
The problem is that port forwarding only forwards a service to a single LAN IP address. In order to
use the same service on a different LAN computer, you have to manually replace the LAN
computer's IP address in the forwarding port with another LAN computer's IP address.
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take
turns using the service. The NBG6716 records the IP address of a LAN computer that sends traffic
to the WAN to request a service with a specific port number and protocol (a "trigger" port). When
the NBG6716's WAN port receives a response with a specific port number and protocol ("incoming"
port), the NBG6716 forwards the traffic to the LAN IP address of the computer that sent the
request. After that computer’s connection for that service closes, another computer on the LAN can
use the service in the same manner. This way you do not need to configure a new IP address each
time you want a different LAN computer to use the application.
14.5.4 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.
Figure 84 Trigger Port Forwarding Process: Example
Jane’s computer
Real Audio Server
Port 7070
Jane requests a file from the Real Audio server (port 7070).
Port 7070 is a “trigger” port and causes the NBG6716 to record Jane’s computer IP address. The
NBG6716 associates Jane's computer IP address with the "incoming" port range of 6970-7170.
The Real Audio server responds using a port number ranging between 6970-7170.
The NBG6716 forwards the traffic to Jane’s computer IP address.
Only Jane can connect to the Real Audio server until the connection is closed or times out. The
NBG6716 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP
(Transfer Control Protocol/Internet Protocol).

14.5.5 Two Points To Remember About Trigger Ports
124
Trigger events only happen on data that is coming from inside the NBG6716 and going to the
outside.
If an application needs a continuous data stream, that port (range) will be tied up so that another
computer on the LAN can’t trigger it.

Static Route
16.1 Overview
This chapter shows you how to configure static routes for your NBG6716.
The NBG6716 usually uses the default gateway to route outbound traffic from computers on the
LAN to the Internet. To have the NBG6716 send data to devices not reachable through the default
gateway, use static routes.
For example, the next figure shows a computer (A) connected to the NBG6716’s LAN interface. The
NBG6716 routes most traffic from A to the Internet through the NBG6716’s default gateway (R1).
You create one static route to connect to services offered by your ISP behind router R2. You create
another static route to communicate with a separate network behind a router R3 connected to the
LAN.

Firewall
17.1 Overview
Use these screens to enable and configure the firewall that protects your NBG6716 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).

Chapter 17 Firewall
What is a Firewall?
Originally, the term “firewall” referred to a construction technique designed to prevent the spread of
fire from one room to another. The networking term "firewall" is a system or group of systems that
enforces an access-control policy between two networks. It may also be defined as a mechanism
used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot
solve every security problem. A firewall is one of the mechanisms used to establish a network
security perimeter in support of a network security policy. It should never be the only mechanism or
method employed. For a firewall to guard effectively, you must design and deploy it appropriately.
This requires integrating the firewall into a broad information-security policy. In addition, specific
policies must be implemented within the firewall itself.
Stateful Inspection Firewall
Stateful inspection firewalls restrict access by screening data packets against defined access rules.
They make access control decisions based on IP address and protocol. They also "inspect" the
session data to assure the integrity of the connection and to adapt to dynamic protocols. These
firewalls generally provide the best speed and transparency; however, they may lack the granular
application level access control or caching that some proxies support. Firewalls, of one type or
another, have become an integral part of standard security solutions for enterprises.
About the NBG6716 Firewall
The NBG6716’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 General tab under Firewall and then click the Enable Firewall check box).
The NBG6716's purpose is to allow a private Local Area Network (LAN) to be securely connected to
the Internet. The NBG6716 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 NBG6716 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 NBG6716 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.

Chapter 17 Firewall
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.

Content Filtering
18.1 Overview
This chapter provides a brief overview of content filtering using the embedded web GUI.
Internet content filtering allows you to create and enforce Internet access policies tailored to your
needs. Content filtering is the ability to block certain web features or specific URL keywords.
18.1.1 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Content Filtering Profiles
Content filtering allows you to block certain web features, such as cookies, and/or block access to
specific web sites. For example, you can configure one policy that blocks John Doe’s access to arts
and entertainment web pages.
A content filtering profile conveniently stores your custom settings for the following features.
Keyword Blocking URL Checking
The NBG6716 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 NBG6716 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 NBG6716 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”.

Web Proxy
A server that acts as an intermediary between a user and the Internet to provide
security, administrative control, and caching service. When a proxy server is located on
the WAN it is possible for LAN users to circumvent content filtering by pointing to this
proxy server.
Enable URL
Keyword Blocking
The NBG6716 can block Web sites with URLs that contain certain keywords in the domain
name or IP address. For example, if the keyword "bad" was enabled, all sites containing
this keyword in the domain name or IP address will be blocked, e.g., URL http://
www.website.com/bad.html would be blocked.

The following section contains additional technical information about the NBG6716 features
described in this chapter.
18.3.1 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 NBG6716 checks the URL’s domain name or IP address when performing keyword
blocking.
This means that the NBG6716 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 NBG6716 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 NBG6716 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.

StreamBoost Management
19.1 Overview
The NBG6716 supports the new StreamBoost technology, introduced by Qualcomm, to redistribute
traffic over the NBG6716 for the best possible performance in a home network.
Streamboost is smart Quality of Service (QoS). Streamboost detects traffic flows and applies traffic
shaping polcies automatically. It gives each device and each application the priority and provides
the exact amount of bandwidth they need at a given time. This helps free up bandwidth for other
applications or connected deivces. 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 the 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 NBG6716 differentiates incoming traffic flows going
from the LAN device (A) or wireless device (B) to the Internet. It shapes traffic and gives priority
and allocate bandwidth according to traffic types.

Universal Plug-and-Play (UPnP)
21.1 Overview
This chapter introduces the UPnP feature in the web configurator.
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
21.2 What You Need to Know
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.
21.2.1 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.
21.2.2 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 NBG6716 allows multicast messages on the LAN only.
NBG6716 User’s Guide

USB Media Sharing
22.1 Overview
This chapter describes how to configure the media sharing settings on the NBG6716.
Note: The read and write performance may be affected by amount of file-sharing traffic
on your network, type of connected USB device and your USB version (1.1 or 2.0).
Media Server
You can set up your NBG6716 to act as a media server to provide media (like video) to DLNAcompliant players, such as Windows Media Player, ZyXEL DMAs (Digital Media Adapters), Xboxes or
PS3s. The media server and clients must have IP addresses in the same subnet.
The NBG6716 media server enables you to:
• Publish all folders for everyone to play media files in the USB storage device connected to the
NBG6716.
• Use hardware-based media clients like the DMA-2500 to play the files.
Note: Anyone on your network can play the media files in the published folders. No user
name and password nor other form of security is required.
The following figure is an overview of the NBG6716’s media server feature. DLNA devices A and B
can access and play files on a USB device (C) which is connected to the NBG6716 (D).

File-Sharing Server
You can also share files on a USB memory stick or hard drive connected to your NBG6716 with
users on your network.
The following figure is an overview of the NBG6716’s file-sharing server feature. Computers A and
B can access files on a USB device (C) which is connected to the NBG6716 (D).
Figure 114 File Sharing Overview
22.2 What You Can Do
• Use the DLNA screen to use the NBG6716 as a media server and allow DLNA-compliant devices
to play media files stored in the attached USB device (Section 22.5 on page 159).
• Use the SAMBA screen to enable file-sharing via the NBG6716 using Windows Explorer or the
workgroup name. This screen also allow you to configure the workgroup name and create user
accounts (Section 22.6 on page 159).
• Use the FTP screen to allow file sharing via the NBG6716 using FTP and create user accounts
(Section 22.7 on page 161).
22.3 What You Need To Know
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 NBG6716 can function as a DLNA-compliant media server and stream
files to DLNA-compliant media clients without any configuration.
NBG6716 User’s Guide
157
Chapter 22 USB Media Sharing
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 NBG6716 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 NBG6716 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 NBG6716. 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.
22.4 Before You Begin
Make sure the NBG6716 is connected to your network and turned on.
158
Connect the USB device to one of the NBG6716’s USB ports.
The NBG6716 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.
