CHAPTER 1
Getting to Know Your NBG
1.1 Overview
This chapter introduces the main features and applications of the NBG.
The NBG upgrades the speed of your existing wireless network, providing faster network access to
mobile users. Making use of IEEE 802.11AC technology, it not only upgrades your network to the
next level but also eliminates dead spots, while offering backward compatibility with other IEEE
802.11b/g/n compatible devices.
A range of services such as a firewall and content filtering are also available for secure Internet
computing. You can use media bandwidth management to efficiently manage traffic on your
network. Bandwidth management features allow you to prioritize time-sensitive or highly important
applications such as Voice over the Internet (VoIP).
1.2 Applications
Your can create the following networks using the NBG:
•Wired. You can connect network devices via the Ethernet ports of the NBG so that they can
communicate with each other and access the Internet.
•Wireless. Wireless clients can connect to the NBG to access network resources.
•WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG
Use any of the following methods to manage the NBG.
• Web Configurator. This is recommended for everyday management of the NBG using a
(supported) web browser.
• Wireless switch. You can use the built-in switch of the NBG to turn the wireless function on and
off without opening the Web Configurator.
• WPS (Wi-Fi Protected Setup) button. You can use the WPS button or the WPS section of the Web
Configurator to set up a wireless network with your NBG.

NBG6515 User’s Guide

1.4 Good Habits for Managing the NBG
Do the following things regularly to make the NBG more secure and to manage the NBG more
effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the NBG to its factory default settings. If you backed
up an earlier configuration file, you would not have to totally re-configure the NBG. You could
simply restore your last configuration.

1.6 The WPS Button
Your NBG supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless
network. 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. Each WPS connection works between two devices. Both
devices must support WPS (check each device’s documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device
to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set
up a secure network by themselves.
For more information on using WPS, see Section 10.3 on page 72.
1.7 Wall Mounting
You may need screw anchors if mounting on a concrete or brick wall.
1Select a position free of obstructions on a wall strong enough to hold the weight of the
device.
2Mark two holes on the wall at the appropriate distance apart for the screws.
WLAN 5 GHz Green On The NBG is ready, but is not sending/receiving data through the
wireless LAN 5 GHz band.
Blinking The NBG is sending/receiving data through the wireless LAN
5 GHz band.
Off The wireless LAN 5 GHz band is not ready or has failed.
USB Green On The NBG has a USB device installed.
Blinking The NBG is transmitting and/or receiving data from routers
through an installed USB device.
Off There is no USB device connected to the NBG.
WPS Green On WPS is enabled.
Blinking The NBG is negotiating a WPS connection with a wireless client.
Off The wireless LAN is not ready or has failed.

Be careful to avoid damaging pipes or cables located inside the wall
when drilling holes for the screws.
3If using screw anchors, drill two holes for the screw anchors into the wall. Push the
anchors into the full depth of the holes, then insert the screws into the anchors. Do not
insert the screws all the way in - leave a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not
insert the screws all the way in - leave a gap of about 0.5 cm.
4Make sure the screws are fastened well enough to hold the weight of the NBG with the
connection cables.
5Align the holes on the back of the NBG with the screws on the wall. Hang the NBG on the
screws.

2.3.3 Connection Type: PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with
a broadband modem (for example DSL, cable, 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 NBG (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the NBG does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.
Figure 8 Internet Connection Type: PPPoE
Primary DNS DNS (Domain Name System) is for mapping a domain name to its corresponding IP address
and vice versa. The DNS server is extremely important because without it, you must know
the IP address of a computer before you can access it. The NBG uses a system DNS server
(in the order you specify here) to resolve domain names for DDNS and the time server.
Enter the primary DNS server's IP address in the fields provided.
Secondary DNS Enter the secondary DNS server's IP address in the fields provided.

2.3.4 Connection Type: PPTP
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers of data from a
remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based
networks.
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks,
such as the Internet.
Refer to the appendix for more information on PPTP.
The NBG supports one PPTP server connection at any given time.
Note: This Internet connection type will be supported in the next firmware version.

CHAPTER 9
Universal Repeater Mode
9.1 Overview
In universal repeater mode, your NBG can act as an access point and wireless client at the same
time. The NBG can connect to an existing network through another access point and also lets
wireless clients connect to the network through it. This helps you expand wireless coverage when
you have an access point or wireless router already in your network.
In the example below, the NBG (A) is configured as a universal repeater. It has three clients that
want to connect to the Internet. The NBG wirelessly connects to the available access point (B).
Figure 46 Universal Repeater Mode
After the NBG and the access point connect, the NBG acquires its IP address from the access point.
The clients of the NBG can now surf the Internet.
9.2 What You Can Do
•Use the Status screen to view read-only information about your NBG (Section 9.5 on page 64).
•Use the AP Select screen to choose an access point that you want the NBG to connect to. You
should know the security settings of the target AP (Section 9.6 on page 67).
•Use other Wireless LAN screens to configure the wireless settings and wireless security
between the wireless clients and the NBG.
•Use the LAN screen to set the IP address for your NBG acting as an access point (Section 8.5 on
page 61).
9.3 What You Need to Know
With the exception of the Network > Wireless LAN 2.4G/5G > AP Select screens, other

10.3 Configuring Wireless Security Using WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the NBG 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.
Chapter 10 Tutorials
NBG6515 User’s Guide
73
•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a
button. See Section 10.3.1 on page 73.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 NBG’s interface. See Section 10.3.2 on page 74. This is
the more secure method, since one device can authenticate the other.
10.3.1 Push Button Configuration (PBC)
1Make sure that your NBG is turned on and that it is within range of your computer.
2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or
WPS button)
4Log into NBG’s Web Configurator and press the Push Button button in the Network > Wireless
LAN 2.4G or Wireless LAN 5G > WPS Device screen.
Note: Your NBG 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 NBG 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 NBG securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both NBG and wireless client (the NWD210N in this example).

When you use the PIN configuration method, you need to use both NBG’s configuration interface
and the client’s utilities.
1Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method
to get a PIN number.
2Enter the PIN number to the PIN field in the Network > Wireless LAN 2.4G or Wireless LAN
5G > WPS Device screen on the NBG.
3Click Start button (or button next to the PIN field) on both the wireless client utility screen and the
NBG’s WPS Device screen within two minutes.
The NBG authenticates the wireless client and 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 NBG securely.

Wireless LAN
11.1 Overview
This chapter discusses how to configure the wireless network settings in your NBG. See the
appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 64 Example of a Wireless Network
The wireless 2.4G network is the part in the blue circle and wireless 5G network is the part in the
green circle. In these wireless networks, devices A, B and C 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.
11.2 What You Can Do
•Use the General screen (Section 11.4 on page 83) to enable the Wireless LAN, enter the SSID
and select the wireless security mode.
•Use the MAC Filter screen (Section 11.6 on page 89) to allow or deny wireless stations based
on their MAC addresses from connecting to the NBG.

•Use the Advanced screen (Section 11.7 on page 90) to allow wireless advanced features, such
as intra-BSS networking and set the RTS/CTS Threshold.
•Use the QoS screen (Section 11.8 on page 91) to set priority levels to services, such as e-mail,
VoIP, chat, and so on.
•Use the WPS screen (Section 11.9 on page 91) to quickly set up a wireless network with strong
security, without having to configure security settings manually.
•Use the WPS Device screen (Section 11.10 on page 92) to add a wireless device using WPS.
•Use the Scheduling screen (Section 11.11 on page 93) to set the times your wireless LAN is
turned on and off.
•Use the Guest WLAN screen (Section 11.12 on page 94) to configure multiple BSSs on the NBG.
11.3 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.
11.3.1 Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless
network.
11.3.1.1 SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the
SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change
the default SSID to something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for unauthorized devices to
get the SSID. In addition, unauthorized devices can still see the information that is sent in the
wireless network.
11.3.1.2 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
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.
Chapter 11 Wireless LAN
NBG6515 User’s Guide
82
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.
11.3.1.3 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.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. Suppose the wireless network has two wireless clients. Device A only supports
WEP, and device B supports WEP and WPA-PSK. Therefore, you should set up WEP in the wireless
network.
Note: It is recommended that wireless networks use WPA-PSK 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.
When you select WPA2-PSK in your NBG, you can also select an option (WPA Compatible) to
support WPA as well. In this case, if some wireless clients support WPA and some support WPA2,
you should set up WPA2-PSK (depending on the type of wireless network login) and select the
WPA Compatible option in the NBG.
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.
11.3.1.4 WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a 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
Number) in the devices. Then, they connect and set up a secure network by themselves. See how
to set up a secure wireless network using WPS in the Section 10.3 on page 72.

11.3.1.5 WDS
Wireless Distribution System or WDS security is used between bridged APs. It is independent of the
security between the wired networks and their respective APs. If you do not enable WDS security,
traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same
pre-shared key.
11.4 General Wireless LAN 2.4G/5G General Screen
Use this screen to enable the Wireless LAN 2.4G or 5G, enter the SSID and enable Guest WLAN.
Note: If you are configuring the NBG from a computer connected to the wireless LAN and
you change the NBG’s SSID, channel or security settings, you will lose your
wireless connection when you press Apply to confirm. You must then change the
wireless settings of your computer to match the NBG’s new settings.
This screen varies depending on whether you chose Static WEP, WPA, WPA2, WPA-PSK or
WPA2-PSK to add security on the selected wireless network. The wireless clients which want to
associate to this network must have same wireless security settings as the NBG. No Security
allows any client to connect to this network without authentication.
If you enable the WPS function, only No Security, Static WEP, WPA-PSK and WPA2-PSK are
available in this field.

11.5.2 WEP Encryption
WEP encryption scrambles the data transmitted between the wireless stations and the access points
to keep network communications private. It encrypts unicast and multicast communications in a
network. Both the wireless stations and the access points must use the same WEP key.
Your NBG allows you to configure up to four 64-bit or 128-bit WEP keys but only one key can be
enabled at any one time.
In order to configure and enable WEP encryption, click Network > Wireless LAN 2.4G or
Wireless LAN 5G to display the General screen. Select Static WEP from the Security Mode list.

CHAPTER 12
IPv6
12.1 IPv6 Overview
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The
increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP
addresses.
Use the IPv6 screens to configure the IP address for your NBG on the LAN or on the WAN.
12.1.1 What You Can Do in this Chapter
•Use the General screen (Section 12.2 on page 98) to configure the IPv6 connection type.
12.1.2 What You Need to Know
IPv6 Addressing
An 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can
be written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can
only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be
written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An
IPv6 prefix length specifies how many most significant bits (start from the left) in the address
compose the network address. The prefix length is written as “/x” where x is a number. For
example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) from the left is the network prefix.
Chapter 12 IPv6
NBG6515 User’s Guide
97
Link-local Address
A link-local address uniquely identifies a device on the local network (the LAN). It is similar to a
“private IP address” in IPv4. You can have the same link-local address on multiple interfaces on a
device. A link-local unicast address has a predefined prefix of fe80::/10. The link-local unicast
address format is as follows.
Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided
into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each
character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal
characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.
Stateless Autoconfiguration
With stateless autoconfiguration in IPv6, addresses can be uniquely and automatically generated.
Unlike DHCPv6 (Dynamic Host Configuration Protocol version six) which is used in IPv6 stateful
autoconfiguration, the owner and status of addresses don’t need to be maintained by a DHCP
server. Every IPv6 device is able to generate its own and unique IP address automatically when
IPv6 is initiated on its interface. It combines the prefix and the interface ID (generated from its own
Ethernet MAC address) to form a complete IPv6 address.
When IPv6 is enabled on a device, its interface automatically generates a link-local address
(beginning with fe80).
When the NBG’s WAN interface is connected to an ISP with a router and the NBG is set to
automatically obtain an IPv6 network prefix from the router for the interface, it generates another
address which combines its interface ID and global and subnet information advertised from the
router. (In IPv6, all network interfaces can be associated with several addresses.) This is a routable
global IP address.
Prefix Delegation
Prefix delegation enables an IPv6 router (the NBG) to use the IPv6 prefix (network address)
received from the ISP (or a connected uplink router) for its LAN. The NBG uses the received IPv6
prefix (for example, 2001:db2::/48) to generate its LAN IP address. Through sending Router
Advertisements (RAs) regularly by multicast, the router passes the IPv6 prefix information to its
LAN hosts. The hosts then can use the prefix to generate their IPv6 addresses.
IPv6 Router Advertisement
An IPv6 router sends router advertisement messages periodically to advertise its presence and
other parameters to the hosts in the same network.

DHCPv6
The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol
that allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other
configuration information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages
using UDP.
Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which is used for
identification when they are exchanging DHCPv6 messages. The DUID is generated from the MAC
address, time, vendor assigned ID and/or the vendor's private enterprise number registered with
the IANA. It should not change over time even after you reboot the device.

CHAPTER 13
WAN
13.1 Overview
This chapter discusses the NBG’s WAN screens. Use these screens to configure your NBG for
Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the
Internet. It connects your private networks such as a LAN (Local Area Network) and other
networks, so that a computer in one location can communicate with computers in other locations.
Figure 77 LAN and WAN
13.2 What You Can Do
•Use the Internet Connection screen (Section 13.4 on page 103) to enter your ISP information
and set how the computer acquires its IP, DNS and WAN MAC addresses.
•Use the Advanced screen (Section 13.5 on page 109) to enable multicasting, configure Windows
networking and bridge.

13.3.1 Configuring Your Internet Connection
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
over Ethernet) 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 NBG, which makes it accessible from an outside
network. It is used by the NBG to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP
encapsulation method).
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, you must know the IP address of a computer before you can access
it.
The NBG can get the DNS server addresses in the following ways.
1The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2If your ISP dynamically assigns the DNS server IP addresses (along with the NBG’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by either using the
factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default
to select the factory assigned default MAC Address.
Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of
the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the
address will be copied to configuration file. It is recommended that you clone the MAC address prior
to hooking up the WAN Port.

13.3.2 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 78 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 NBG supports both IGMP version 1
(IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the NBG queries all directly connected networks to gather group membership. After
that, the NBG periodically updates this information. IP multicasting can be enabled/disabled on the
NBG LAN and/or WAN interfaces in the Web Configurator (LAN; WAN). Select None to disable IP
multicasting on these interfaces.

13.4.2 PPPoE Encapsulation
The NBG 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 NBG (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the NBG does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

CHAPTER 14
LAN
14.1 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. The LAN screens can help you configure a LAN DHCP server, manage IP
addresses, and partition your physical network into logical networks.
Figure 83 LAN Example
The LAN screens can help you manage IP addresses.
14.2 What You Can Do
•Use the IP screen (Section 14.4 on page 112) to change the IP address for your NBG.
14.3 What You Need To Know
The actual physical connection determines whether the NBG ports are LAN or WAN ports. There are
two separate IP networks, one inside the LAN network and the other outside the WAN network as
shown next.
Chapter 14 LAN
NBG6515 User’s Guide
112
Figure 84 LAN and WAN IP Addresses
The LAN parameters of the NBG 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.
14.3.1 IP Pool Setup
The NBG 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 NBG 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.
14.3.2 LAN TCP/IP
The NBG has built-in DHCP server capability that assigns IP addresses and DNS servers to systems
that support DHCP client capability.
14.3.3 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The NBG supports three logical LAN interfaces via its single physical Ethernet
interface with the NBG itself as the gateway for each LAN network.

obtain TCP/IP configuration at start-up from a server. You can configure the NBG’s LAN as a DHCP
server or disable it. When configured as a server, the NBG 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.
15.2 What You Can Do
•Use the General (Section 15.3 on page 114) screen to enable the DHCP server.

Network Address Translation (NAT)
16.1 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.
Each packet has two addresses – a source address and a destination address. For outgoing packets,
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 NBG keeps track of the original addresses and port numbers so
incoming reply packets can have their original values restored. The following figure illustrates this.
Figure 88 NAT Example
For more information on IP address translation, refer to RFC 1631, The IP Network Address
Translator (NAT).
16.2 What You Can Do
•Use the General screen (Section 16.3 on page 118) to enable NAT and set a default server.
•Use the Application screen (Section 16.4 on page 118) o forward incoming service requests to

16.4 NAT Application Screen
Use the Application 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.

16.5 NAT Advanced Screen
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 NBG 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
NBG's WAN port receives a response with a specific port number and protocol ("incoming" port),
the NBG 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.
To change your NBG’s trigger port settings, click Network > NAT > Advanced. The screen
appears as shown.
Note: Only one LAN computer can use a trigger port (range) at a time.

2Port 7070 is a “trigger” port and causes the NBG to record Jane’s computer IP address. The NBG
associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The NBG forwards the traffic to Jane’s computer IP address.

DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access
your FTP server or Web site on your own computer using a domain name (for instance
myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an
IP address that changes each time you reconnect. Your friends or relatives will always be able to
call you even if they don't know your IP address.

CHAPTER 18
Static Route
18.1 Overview
This chapter shows you how to configure static routes for your NBG.
Each remote node specifies only the network to which the gateway is directly connected, and the
NBG has no knowledge of the networks beyond. For instance, the NBG knows about network N2 in
the following figure through remote node Router 1. However, the NBG is unable to route a packet to
network N3 because it doesn't know that there is a route through the same remote node Router 1
(via gateway Router 2). The static routes are for you to tell the NBG about the networks beyond the
remote nodes.

CHAPTER 19
Firewall
19.1 Overview
This chapter shows you how to enable and configure the firewall that protects your NBG and your
LAN from unwanted or malicious traffic.
Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and
control access between the LAN and WAN. By default the firewall:
• allows traffic that originates from your LAN computers to go to all of the networks.
• blocks traffic that originates on the other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant
Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2).
However other traffic initiated from the WAN is blocked (3 and 4).
Figure 96 Default Firewall Action
19.2 What You Can Do
•Use the General (Section 19.4 on page 128) screen to enable or disable the NBG’s firewall.
•Use the MAC Filtering Rule screen (Section 19.5 on page 129) to configure the NBG to block

19.3 What You Need To Know
The NBG’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 designed to protect against Denial of Service (DoS) attacks when activated (click the General
tab under Firewall and then click the Enable Firewall check box). The NBG's purpose is to allow a
private Local Area Network (LAN) to be securely connected to the Internet. The NBG 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 NBG 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 NBG 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.

CHAPTER 20
Content Filter
20.1 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.
20.2 What You Can Do
Use the Content Filter (Section 20.4 on page 135) screen to restrict web features, add
keywords for blocking and designate a trusted computer.
20.3 What You Need To Know
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.
20.3.1 Content Filtering Profiles
A content filtering profile conveniently stores your custom settings for the following features.
Restrict Web Features
The NBG can disable web proxies and block web features such as ActiveX controls, Java applets and
cookies.
Keyword Blocking URL Checking
The NBG 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.
Chapter 20 Content Filter
NBG6515 User’s Guide
135
Since the NBG 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 NBG 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”.

Bandwidth Management
21.1 Overview
This chapter contains information about configuring bandwidth management and editing rules.
ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an
application.
In the figure below, uplink traffic goes from the LAN device (A) to the WAN device (B). Bandwidth
management is applied before sending the packets out to the WAN. Downlink traffic comes back
from the WAN device (B) to the LAN device (A). Bandwidth management is applied before sending
the traffic out to LAN.

Remote Management
22.1 Overview
This chapter provides information on the Remote Management screens.
Remote Management allows you to manage your NBG from a remote location through the following
interfaces:
•LAN and WAN
•LAN only
•WAN only
Note: The NBG is managed using the Web Configurator.
22.2 What You Can Do
Use the WWW screen (Section 22.4 on page 143) to define the interface/s from which the NBG can
be managed remotely and specify a secure client that can manage the NBG.
22.3 What You Need to Know
Remote management over LAN or WAN will not work when:
1The IP address in the Secured Client IP Address field (Section 22.4 on page 143) does not
match the client IP address. If it does not match, the NBG will disconnect the session immediately.
2There is already another remote management session. You may only have one remote
management session running at one time.
3There is a firewall rule that blocks it.
22.3.1 Remote Management and NAT
When NAT is enabled:
• Use the NBG’s WAN IP address when configuring from the WAN.
• Use the NBG’s LAN IP address when configuring from the LAN.

CHAPTER 23
Universal Plug-and-Play (UPnP)
23.1 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.
23.2 What You Can Do
Use the UPnP screen (Section 23.4 on page 145) to enable UPnP on your NBG.
23.3 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.
23.3.1 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.
Chapter 23 Universal Plug-and-Play (UPnP)
NBG6515 User’s Guide
145
23.3.2 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 NBG allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.

CHAPTER 24
USB Media Sharing
24.1 Overview
This chapter describes how to configure the media sharing settings on the NBG.
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 NBG to act as a media server to provide media (like video) to DLNA-compliant
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 NBG media server enables you to:
• Publish all folders for everyone to play media files in the USB storage device connected to the
NBG.
• 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 NBG’s media server feature. DLNA devices A and B can
access and play files on a USB device (C) which is connected to the NBG (D).

File-Sharing Server
You can also share files on a USB memory stick or hard drive connected to your NBG with users on
your network.
The following figure is an overview of the NBG’s file-sharing server feature. Computers A and B can
access files on a USB device (C) which is connected to the NBG (D).
Figure 119 File Sharing Overview
24.2 What You Can Do
•Use the SMB/CIFS screen to enable file-sharing via the NBG using Windows Explorer or the
workgroup name. This screen also allow you to configure the workgroup name and create user
accounts (Section 24.5 on page 154).
•Use the DLNA screen to use the NBG as a media server and allow DLNA-compliant devices to
play media files stored in the attached USB device (Section 24.6 on page 155).
•Use the FTP screen to allow file sharing via the NBG using FTP and create user accounts (Section
24.7 on page 155).
24.3 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 NBG 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 NBG 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 NBG 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 NBG. 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.
24.4 Before You Begin
Make sure the NBG is connected to your network and turned on.
1Connect the USB device to one of the NBG’s USB ports.
2The NBG 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.

If the NBG is sending or receiving a lot of information, try closing some programs that use the
Internet, especially peer-to-peer applications.
2Check the signal strength. If the signal strength is low, try moving the NBG closer to the AP if
possible, and look around to see if there are any devices that might be interfering with the wireless
network (for example, microwaves, other wireless networks, and so on).
3Reboot the NBG.
4If the problem continues, contact the network administrator or vendor, or try one of the advanced
suggestions.
Advanced Suggestions
• Check the settings for bandwidth management. If it is disabled, you might consider activating it.
If it is enabled, you might consider changing the allocations.

• Check the settings for QoS. If it is disabled, you might consider activating it. If it is enabled, you
might consider raising or lowering the priority for some applications.
I set up URL keyword blocking, but I can still access a website that should be blocked.
Make sure that you select the Enable URL Keyword Blocking check box in the Content Filtering
screen. Make sure that the keywords that you type are listed in the Keyword List.
If a keyword that is listed in the Keyword List is not blocked when it is found in a URL, customize
the keyword blocking using commands. See the Customizing Keyword Blocking URL Checking
section in the Content Filter chapter.
26.4 Resetting the NBG to Its Factory Defaults
If you reset the NBG, you lose all of the changes you have made. The NBG re-loads its default
settings, and the password resets to 1234. You have to make all of your changes again.
You will lose all of your changes when you push the RESET button.
To reset the NBG,
1Make sure the power LED is on.
2Press the RESET button for longer than 1 second to restart/reboot the NBG.
3Press the RESET button for longer than five seconds to set the NBG back to its factory-default
configurations.
If the NBG restarts automatically, wait for the NBG to finish restarting, and log in to the Web
Configurator. The password is “1234”.
If the NBG does not restart automatically, disconnect and reconnect the NBG’s power. Then, follow
the directions above again.
26.5 Wireless Router/AP Troubleshooting
I cannot access the NBG or ping any computer from the WLAN (wireless AP or router).
1Make sure the wireless LAN is enabled on the NBG

2Make sure the wireless adapter on the wireless station is working properly.
3Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports
the same wireless standard as the NBG.
4Make sure your computer (with a wireless adapter installed) is within the transmission range of the
NBG.
5Check that both the NBG and your wireless station are using the same wireless and wireless
security settings.
6Make sure traffic between the WLAN and the LAN is not blocked by the firewall on the NBG.
7Make sure you allow the NBG to be remotely accessed through the WLAN interface. Check your
remote management settings.
• See the chapter on Wireless LAN in the User’s Guide for more information.
I cannot access the Web Configurator after I switched to AP mode.
192.168.1.1 is the default IP in Router mode (the default mode). In AP mode the default IP is
192.168.1.2. So, when you switch from Router mode to AP mode, you need to use the AP mode IP to
log in.
26.6 USB Device Problems
I cannot access or see a USB device that is connected to the NBG.
1Be sure to install the ZyXEL NetUSB Share Center Utility (for NetUSB functionality) first from the
included disc, or download the latest version from the zyxel.com website.
2Disconnect the problematic USB device, then reconnect it to the NBG.
3Ensure that the USB device has power.
4Check your cable connections.
5Restart the NBG by disconnecting the power and then reconnecting it.
6If the USB device requires a special driver, install the driver from the installation disc that came
with the device. After driver installation, reconnect the USB device to the NBG and try to connect to
it again with your computer.
7If the problem persists, contact your vendor.

What kind of USB devices do the NBG support?
1It 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 NBG.
