1.2 Se c uring the NBG- 418N v2
Do the following things regularly to make the NBG-418N v2 more secure and to manage the NBG-418N
v2 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-418N v2 to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the NBG-418N v2. You could
simply restore your last configuration.

Depending on the devices you have, you can either press a button (recommended) 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.
The WPS/ RESET single button is located at the back panel of the NBG-418N v2.
1.4.1 Using the WPS/ RESET Button
1 Make sure the power LED is on.
2 Press the WPS/ RESET button within 3 seconds to turn on the WPS function

2.1 O ve rvie w
This chapter describes how to access the NBG-418N v2 Web Configurator and provides an overview of
its screens.
The Web Configurator is an HTML-based management interface that allows easy setup and
management of the NBG-418N v2 via Internet browser. Use Internet Explorer 8.0 and later versions,
Mozilla Firefox, Google Chrome or Safari. The recommended screen resolution is 1024 by 768 pixels.
In order to use the Web Configurator you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in
Windows XP SP (Service Pack) 2.
• JavaScript (enabled by default).
• Java permissions (enabled by default).
C HAPTER 2

Refer to
Explorer.
Chapter 23 Troubleshooting to see how to make sure these functions are allowed in Internet
2.2 Ac c e ssing the We b Config ura to r
1 Make sure your NBG-418N v2 hardware is properly connected and prepare your computer or computer
network to connect to the NBG-418N v2 (refer to the Quick Start Guide).
2 Launch your web browser.
3 When the NBG-418N v2 is in router mode, type “http://myrouter” or "http://192.168.1.1" as the website
address in your web browser. 192.168.1.1 is the default LAN IP address in router mode (the default
device mode). (The default IP address in non-router mode is 192.168.1.2).
Your computer must be in the same subnet in order to access this website address. In router mode, the
NBG-418N v2 can assign your computer an IP address, so you must set your computer to get an IP
address automatically (computer factory default) or give it a fixed IP address in the range between
192.168.1.3 and 192.168.1.254 (see the appendices).
4 Type a d m in (default) as the user name and 12 34 (default) as the password and click O K.

3.2.1 PPPoE Conne c tio n
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.
NBG-418N v2 User’s Guide

Chapter 3 Connection Wizard
By implementing PPPoE directly on the NBG-418N v2 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG-418N v2 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.

Bandwidth management provides a convenient way to manage the use of various services on the
network. It manages general protocols (for example, HTTP and FTP) and applies traffic prioritization to
enhance the performance of delay-sensitive applications like voice and video.
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.

Chapter 6 Wireless LAN
6.3 Wha t Yo u Should Kno w
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.
6.3.1 Wire le ss Sec urity O ve rvie w
The following sections introduce different types of wireless security you can set up in the wireless
network.
6.3.2 MBSSID
Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well as the
cost of buying extra APs, there is also the possibility of channel interference. The NBG-418N v2’s MBSSID
(Multiple Basic Service Set IDentifier) function allows you to use one access point to provide several BSSs
simultaneously. You can then assign varying security modes to different SSIDs.
Wireless devices can use different BSSIDs to associate with the same AP.
6.3.2.1 Note s on Multip le BSSs
• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use different keys for different BSSs. If two wireless devices have different BSSIDs (they are in
different BSSs), but have the same keys, they may hear each other’s communications (but not
communicate with each other).
• MBSSID should not replace but rather be used in conjunction with 802.1x security.
6.3.3 MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is
usually written using twelve hexadecimal characters
To get the MAC address for each wireless client, see the appropriate User’s Guide or other
documentation.
2
; for example, 00A0C5000002 or 00:A0:C5:00:00:02.
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.
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.
NBG-418N v2 User’s Guide
62
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.
6.3.4 Enc ryption
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.
Table 18 Types of Encryption for Each Type of Authentication
We ake st No Security
Strong e st WPA2-PSK
For example, if users do not log in to the wireless network, you can choose no encryption, WEP, WPA-PSK,
or WPA2-PSK.
Chapter 6 Wireless LAN
NO AUTHENTIC ATIO N
Static WEP
WPA-PSK
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 WPA2-PSK. Therefore, you should set up WEP in the wireless network.
Note: It is recommended that wireless networks use WPA2-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.
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.
6.3.5 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 5.3 on page 46.

Enc a psulation Me thod
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.

Chapter 7 WAN
WAN IP Add re ss
The WAN IP address is an IP address for the NBG-418N v2, which makes it accessible from an outside
network. It is used by the NBG-418N v2 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG-418N v2 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 Serve r Add re ss Assignm e nt
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-418N v2 can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up.
If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the NBG-418N v2’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
WAN MAC Add re ss
The MAC address screen allows users to configure the WAN port's MAC address by either using the

wireless, etc.) connection. The PPP o ve r Etherne t option is for a dial-up connection using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example Radius).
NBG-418N v2 User’s Guide

Chapter 7 WAN
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-418N v2 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG-418N v2 does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

8.1 O ve rvie w
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.

The LAN screens can help you configure a LAN DHCP server and manage IP addresses.
8.2 Wha t Yo u Ne e d To Kno w
The actual physical connection determines whether the NBG-418N v2 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 8 LAN
Figure 69 LAN and WAN IP Addresses
The LAN parameters of the NBG-418N v2 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.
8.2.1 IP Addre ss a nd Subne t Ma sk
Similar to the way houses on a street share a common street name, so too do computers on a LAN share
one common network number.
Where you obtain your network number depends on your particular situation. If the ISP or your network
administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP
addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user
account and the ISP will assign you a dynamic IP address when the connection is established. The
Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use;
please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the
network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255
are reserved). In other words, the first three numbers specify the network number while the last number
identifies an individual computer on that network.
Once you have decided on the network number, pick an IP address that is easy to remember, for
instance, 192.168.1.1, for your NBG-418N v2, but make sure that no other device on your network is using
that IP address.
The subnet mask specifies the network number portion of an IP address. Your NBG-418N v2 will compute
the subnet mask automatically based on the IP address that you entered. You don't need to change
the subnet mask computed by the NBG-418N v2 unless you are instructed to do otherwise.
8.2.2 DNS Se rve r Addre ss Assig nme nt
Use DNS (Domain Name System) 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.
NBG-418N v2 User’s Guide
97
The NBG-418N v2 can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up.
If your ISP gives you DNS server addresses, enter them in the DNS Se rve r fields in the Wizard and/or WAN
> Interne t C onne ctio n screen.
2 If the ISP did not give you DNS server information, leave the DNS Se rve r fields set to 0.0 .0.0 in the Wiza rd
screen and/or set to Fro m ISP in the WAN > Inte rne t Co nne ctio n screen for the ISP to dynamically assign
the DNS server IP addresses.
8.2.3 IP Po o l Se tup
The NBG-418N v2 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-418N v2 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.
8.2.4 LAN TC P/ IP
The NBG-418N v2 has built-in DHCP server capability that assigns IP addresses and DNS servers to systems
that support DHCP client capability.

9.1 O ve rvie w
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 NBG-418N v2’s LAN as a DHCP
server or disable it. When configured as a server, the NBG-418N v2 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.
