1.1 Overview
This chapter introduces the main features and applications of the NBG2105.
The NBG2105 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 802.11b/g/
n compatible devices.
A range of services such as a firewall and content filtering are also available for secure Internet
computing.
1.2 Applications
CHAPTER 1
Introduction
Your can have the following networks using the NBG2105:
• Wired. You can connect network devices via the Ethernet ports of the NBG2105 so that they can
communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the NBG2105 to access network resources. You can
use WPS (WiFi 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 NBG2105
Use any of the following methods to manage the NBG2105.
• 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 NBG2105 using a
(supported) web browser.
1.4 Good Habits for Managing the NBG2105
Do the following things regularly to make the NBG2105 more secure and to manage the NBG2105
more effectively.
NBG2105 User’s Guide 13
Chapter 1 Introduction
• 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 NBG2105 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG2105.
You could simply restore your last configuration.
1.5 Resetting the NBG2105
If you forget your password or IP address, or you cannot access the Web Configurator, you will need
to use the RESET button on the underside of the NBG2105 to reload the factory-default
configuration file. This means that you will lose all configurations that you had previously saved, the
password and the IP address will be reset to the defaults shown on the cover of this user’s guide.
1.5.1 How to Use the RESET Button
1 Make sure the power LED is on.
2 Press the RESET button for longer than five seconds (when the power LED begins to blink) and
release it to set the NBG2105 back to its factory-default configurations.
1.6 The WPS Button
Your NBG2105 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.
You can use the WPS button to activate WPS in order to quickly set up a wireless network with
strong security.
1 Make sure the power LED is on (not blinking).
2 Press the WPS button for less than two seconds and release it. Press the WPS button on another
WPS-enabled device within range of the NBG2105.
14
NBG2105 User’s Guide
Note: You must activate WPS in the NBG2105 and in another wireless device within two
minutes of each other.
For more information on using WPS, see Section 8.2 on page 59.
1.7 The Clone MAC Button
Your NBG2105 can clone the MAC address of the computer connected to the NBG2105. It is
recommended that you clone the MAC address prior to hooking up the WAN port or connecting to
an AP or wireless router with Internet access.
Note: MAC cloning is supported only when the NBG2105 is in Router mode.
1.7.1 Cloning a computer's MAC address
1 Make sure the power LED is on (not blinking).
2 To copy and use the MAC address of a currently connected computer through a wired Ethernet or
wireless LAN connection, press the Clone MAC button for two to five seconds and release it.
Chapter 1 Introduction
3 The WPS/MAC Clone LED turns on when the clone was successful.
4 The NBG2105 restarts automatically ten seconds after you press the Clone MAC button.
1.7.2 Restoring the default MAC address
1 Make sure the power LED is on (not blinking).
2 Press and hold the Clone MAC button for more than five seconds to reset the NBG2105 back to the
factory default MAC address. The Clone MAC Address in the WAN screen shows 000000000000 to
indicate the NBG2105 is using the factory default MAC address.
3 The NBG2105 restarts after you press the Clone MAC button.

3.1 Overview
This chapter introduces the operation modes available on your NBG2105 and how to configure
them. The operation mode is a pre-defined combination of routing, access point (AP) and wireless
client functions to match your network topology and requirements. Use the Operation Mode switch
on the right-side panel (see Section 1.8 on page 16) of the NBG2105 to select the operation mode.
Use the Router Operation Mode screen to configure the selected mode.
3.2 What You Can Do
• Router mode connects the local network to another network, like the Internet. See Section 3.3
on page 21 for details of this mode.
• Access Point mode extends your network by allowing network devices to connect to the
NBG2105 wirelessly. See Section 3.4 on page 24 for details of this mode.
• Client mode enables the NBG2105 to be a wireless client to an upstream AP.
See Section 3.5 on page 27 for details of this mode.
• WISP + UR mode enables the NBG2105 to connect your local network to the Internet through
an ISP’s access point. UR provides Wi-Fi functionality to clients on the LAN side. See Section 3.6
on page 29 for details of this mode.
CHAPTER 3
Operation Modes
Note: Choose your operation mode carefully to avoid having to change it later. If you
select the incorrect operation mode you may not be able to connect to the Internet.
When changing to another mode, the IP address of the NBG2105 changes. The
running applications and services of the network devices connected to the
NBG2105 can be interrupted.
Note: In WISP + UR and Client modes, you should know the SSID and wireless security
details of the access point to which you want to connect.
3.3 Router Mode
A router connects your local network with another network, such as the Internet. The router has
two IP addresses, the LAN IP address and the WAN IP address. This mode offers services such as a
firewall, QoS or DDNS.

WISP+UR
Access Point
In WISP (Wireless ISP) + UR (Universal Repeater) mode, your NBG2105 can act as a wireless client
to wirelessly connect to the Internet or an existing network via an access point. In addition, it can
provide Wi-Fi function to the clients on the LAN side. Use this mode if you want to wirelessly
connect to the Internet or have an access point or wireless router in your network. In WISP + UR
mode, the IP address of the device on the local network is 192.168.1.2.
Note: Make sure your network and the remote network are NOT in the same subnet. If
the access point or wireless router is using 192.168.1.x, the NBG2105 in WISP +
UR mode needs to use something else, say 192.168.2.x.
Note: When the NBG2105 is in WISP + UR mode, you still need to enter your ISP
information in the WAN screen in order to access the Internet.
In the example below, one NBG2105 is configured as WISP +UR mode (A) and another is used as
an access point (B). The NBG2105 (A) wirelessly connects to the available access point (B), and
can allow the clients (x and y) to access the network through it using a wireless connection.

4.3.3 WAN Access 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.
Chapter 4 Router Setup Wizard
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 NBG2105 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG2105 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.
Select PPPoE as the WAN Access Type to make the WAN port setup its IP configuration via
PPPoE. Complete the fields described. Click Next to proceed with the Wireless Network Name
(SSID) screen.

The NBG2105 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 PPPoE 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.
Chapter 7 WISP+UR Setup Wizard
By implementing PPPoE directly on the NBG2105 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG2105 does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

8.1 Overview
This chapter provides tutorials for setting up your NBG2105.
• Set Up a Wireless Network with WPS
• Configure Wireless Security without WPS
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 NBG2105 as the AP and NWD210N as the wireless client which connects to a notebook.
Tutorials
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 59.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 NBG2105’s interface. See Section 8.2.2 on page 60. This
is the more secure method, since one device can authenticate the other.
8.2.1 Push Button Configuration (PBC)
1 Make sure that your NBG2105 is turned on and working as an AP or wireless router. Make sure that
the device is placed within range of your notebook.
2 Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
3 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or
WPS button)

9.1 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 and manage IP
addresses.
Figure 40 LAN Example
CHAPTER 9
LAN
9.2 What You Can Do
•Use the LAN Interface Setup screen to change the IP address for your NBG2105 (Section 9.4
on page 70).
•Use the Active DHCP Client screen to see which DHCP clients have accepted their IP
configuration from the NBG2105 (Section 9.4.1 on page 71).
9.3 What You Need To Know
The LAN parameters of the NBG2105 are preset in the factory with the following values:
• IP address of 192.168.1.1 (Router mode) or 192.168.1.2 (non-router modes) with subnet mask
of 255.255.255.0 (24 bits)
• DHCP server enabled (Router mode or WISP+UR mode) with client IP addresses starting from
192.168.1.100 and ending with 192.168.1.200.
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.
NBG2105 User’s Guide 69
Chapter 9 LAN
9.3.1 IP Pool Setup
The NBG2105 is pre-configured with a pool of IP addresses starting from 192.168.1.100 to
192.168.1.200. This configuration leaves 98 IP addresses (excluding the NBG2105 itself) under
192.168.1.99 for other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that
you may have.

10.1 Overview
This chapter discusses the NBG2105’s WAN screens. Use these screens to configure your NBG2105
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.
10.2 What You Can Do
You can configure your WAN interface to access your ISP in the following ways.
CHAPTER 10
WAN
• Static IP allows you to configure all NBG2105 WAN IP configuration settings manually (Section
10.4.1 on page 74).
• DHCP Client allows the NBG2105 to get its IP configuration from a DHCP server (Section 10.4.2
on page 75).
• PPPoE allows the NBG2105 to connect via the Point-to-Point Protocol over Ethernet (Section
10.4.3 on page 76).
10.3 What You Need To Know
The information in this section can help you configure the screens for your WAN connection.
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), they should also provide a username and password (and service name) for user
authentication.
NBG2105 User’s Guide 73
Chapter 10 WAN
WAN IP Address
The WAN IP address is an IP address for the NBG2105, which makes it accessible from an outside
network. It is used by the NBG2105 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG2105 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 NBG2105 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 NBG2105’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
WAN MAC Address
The WAN port's MAC address can be configured by either using the factory default or cloning the
MAC address from a computer on your LAN. Choose Clear Mac Clone to select the factory assigned
default MAC Address.
Otherwise, press the Clone MAC address button on the side of the NBG2105 to clone the MAC
address of the computer connected to the NBG2105. 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.
10.4 WAN Interface Setup
Click Network > WAN to change how your NBG2105’s WAN interface accesses your ISP. The
screen differs according to the WAN Access Type you choose.

11.1 Overview
Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and
the networking methods used to control the use of bandwidth. Without QoS, all traffic data is
equally likely to be dropped when the network is congested. This can cause a reduction in network
performance and make the network inadequate for time-critical application such as video-ondemand.
Configure QoS on the NBG2105 to reserve bandwidth for certain traffic based on the IP address or
MAC address.

13.1 Overview
This chapter discusses how to configure the wireless network settings in your NBG2105. See the
appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 48 Example of a Wireless Network
CHAPTER 13
Wireless LAN
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 NBG2105 is the AP.
13.1.1 What You Can Do
•Use the Basic screen to turn the wireless connection on or off and make other basic
configuration changes (Section 13.2 on page 86).
•Use the Advanced screen to configure wireless advanced features, such as the output power
and set the RTS/CTS Threshold (Section 13.4 on page 88).
•Use the Security screen to set up wireless security between the NBG2105 and the wireless
clients (Section 13.5 on page 89).
NBG2105 User’s Guide 83
Chapter 13 Wireless LAN
•Use the Site Survey screen to scan for and connect to a wireless network automatically. (Section
13.6 on page 92)
•Use the WPS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 13.8 on page 95).
•Use the MAC Filtering screen to allow or deny wireless stations based on their MAC addresses
from connecting to the NBG2105 (Section 13.9 on page 97).
13.1.2 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.
Authentication
Authentication is the process of confirming a client’s user name and password when they connect to
a network. Turning off authentication means allowing anyone to connect to the network.
Encryption
Wireless networks can use encryption to protect the information that is sent in the wireless
network. It is the process of taking data and encoding it, usually using a secret code, so that it
becomes unreadable unless decrypted with the proper code or pass phrase. If you do not know the
secret code, you cannot understand the message.

NBG2105 User’s Guide
Chapter 13 Wireless LAN
WEP
Data Encryption
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the
NBG2105 and the AP or other wireless stations to keep network communications private. Both the
wireless stations and the access points must use the same WEP key for data encryption and
decryption.
Authentication Type
The IEEE 802.11b/g/n standard describes a simple authentication method between the wireless
stations and AP. Three authentication types are defined: Both, Open and Shared.
• Open mode is implemented for ease-of-use and when security is not an issue. The wireless
station and the AP or peer computer do not share a secret key. Thus the wireless stations can
associate with any AP or peer computer and listen to any transmitted data that is not encrypted.
• Shared mode involves a shared secret key to authenticate the wireless station to the AP or peer
computer. This requires you to enable the wireless LAN security and use same settings on both
the wireless station and the AP or peer computer.
• Both authentication mode allows the NBG2105 to switch between the open system and shared
key modes automatically. Use this mode if you do not know the authentication mode of the other
wireless stations.
WPA-PSK and WPA2-PSK
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a
wireless security standard that defines stronger encryption, authentication and key management
than WPA.
Key differences between WPA(2) and WEP are improved data encryption and user authentication.
Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP),
Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption
Standard (AES) in the Counter mode with Cipher block chaining Message authentication code
Protocol (CCMP) to offer stronger encryption than TKIP.
The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference
between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific
credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force
password-guessing attacks but it’s still an improvement over WEP as it employs a consistent,
single, alphanumeric password to derive a PMK which is used to generate unique temporal
encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of
WEP)
If both an AP and the wireless clients support WPA2-PSK, use WPA2-PSK for stronger data
encryption. If the AP or the wireless clients do not support WPA2-PSK, just use WPA-PSK. Select
WEP only when the AP and/or wireless clients do not support WPA-PSK or WPA2-PSK. WEP is less
secure than WPA-PSK or WPA2-PSK.
NBG2105 User’s Guide

Chapter 13 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 characters
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.

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 8.2 on page 59.

(Allow Listed) or exclude devices from accessing the NBG2105 (Deny Listed). 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. You
need to know the MAC address of the devices to configure this screen.
To change your NBG2105’s MAC filter settings, click Wireless LAN > MAC Filtering.

14.1 Overview
This chapter shows you how to enable and configure the NBG2105 firewall settings.
The NBG2105 firewall is a packet filtering firewall and restricts access based on the source/
destination computer network address of a packet and the type of application.
14.2 What You Can Do
•Use the Port Filtering screen to apply filtering based on UDP or TCP port numbers (Section 14.4
on page 100).
•Use the IP Filtering screen to apply filtering based on IP addresses (Section 14.5 on page 101).
•Use the MAC Filtering to apply filtering based on MAC addresses (Section 14.6 on page 101).
•Use the URL Filtering to apply filtering based on URLs (Section 14.7 on page 102).

14.3 What You Need To Know
The following terms and concepts may help as you read through this chapter.
What is a Firewall?
A "firewall" is a system or group of systems that enforces an access-control policy between two
networks. Of course, firewalls cannot solve every security problem.
Guidelines For Enhancing Security
1 Change the default password via Web Configurator.
2 Think about access control before you connect to the network in any way, including attaching a
modem to the port.
3 Limit who can access your router.
4 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.

5 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.
6 Keep the NBG2105 in a secured (locked) room.
