CHAPTER 1
Introduction
1.1 Overview
This chapter introduces the main features and applications of the NBG5615.
The NBG5615 extends the range of your existing wired network without additional wiring, providing
easy network access to mobile users. You can set up a wireless network with other IEEE 802.11a/b/
g/n compatible devices. The NBG5615 is able to function both 2.4GHz and 5GHz networks at the
same time.
A range of services such as a firewall and content filtering are also available for secure Internet
computing.
There are two USB 2.0 ports on the side panel of your NBG5615. You can connect USB (version 2.0
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG5615
automatically detects the USB devices.
Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB
storage devices (such as memory sticks, USB hard drives) and/or USB devices
(such as USB printers). Other USB products are not guaranteed to function
properly with the NBG5615.
Note: Be sure to install the ZyXEL NetUSBTM Share Center Utility (for NetUSB
functionality) from the included disc, or download the latest version from the
zyxel.com website.
1.2 Applications
Your can have the following networks using the NBG5615:
•W ired. You can connect network devices via the Ethernet ports of the NBG5615 so that they can
communicate with each other and access the Internet.
•W ireless. Wireless clients can connect to the NBG5615 to access network resources. You can
use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-
compatible device.
•W AN. Connect to a broadband modem/router for Internet access.
•NetUSB. The NBG5615 allows you to connect a USB device (such as printer, or scanner) directly
to the USB port and then share that device over the network using the NetUSB utility.
Chapter 1 Introduction
NBG5615 User’s Guide

1.3 Ways to Manage the NBG5615
Use any of the following methods to manage the NBG5615.
• 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 NBG5615 using a
(supported) web browser.
1.4 Good Habits for Managing the NBG5615
Do the following things regularly to make the NBG5615 more secure and to manage the NBG5615
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 NBG5615 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG5615.
You could simply restore your last configuration.
1.5 Resetting the NBG5615
If you forget your password or IP address, or you cannot access the Web Configurator, you will need
to use the RESET button at the back of the NBG5615 to reload the factory-default configuration
file. This means that you will lose all configurations that you had previously saved, the password
will be reset to “1234” and the IP address will be reset to “192.168.1.1”.
1.5.1 How to Use the RESET Button
1Make sure the power LED is on.
2Press the RESET button for one to four seconds to restart/reboot the NBG5615.
3Press the RESET button for longer than five seconds to set the NBG5615 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG5615 supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure
wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance.
Chapter 1 Introduction
NBG5615 User’s Guide 17
WPS allows you to quickly set up a wireless network with strong security, without having to
configure security settings manually. Each WPS connection works between two devices. Both
devices must support WPS (check each device’s documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device
to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set
up a secure network by themselves.
You can use the WPS button ( ) on the front panel of the NBG5615 to activate WPS in order to
quickly set up a wireless network with strong security.
1Make sure the power LED is on (not blinking).
2Press the WPS button for more than three seconds and release it. Press the WPS button on another
WPS-enabled device within range of the NBG5615.
Note: You must activate WPS in the NBG5615 and in another wireless device within two
minutes of each other.
For more information on using WPS, see Section 9.2 on page 73.

1.8 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.
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 NBG5615 with the
connection cables.

3.3 Connect to Internet
The NBG5615 offers three Internet connection types. They are I PoE, PPPoE or PPTP. The wizard
attempts to detect which WAN connection type you are using.
Figure 8 Detecting your Internet Connection Type
If the wizard does not detect a connection type, you must select one from the drop-down list box.
Check with your ISP to make sure you use the correct type.
Note: If you get an error message, check your hardware connections. Make sure your
Internet connection is up and running.
The following screen depends on your Internet connection type. Enter the details provided by your
Internet Service Provider (ISP) in the fields (if any).

Note: If you get an error screen after clicking Next, you might have selected the wrong
Internet Connection type. Click Back, make sure your Internet connection is
working and select the right Connection Type. Contact your ISP if you are not sure
of your Internet Connection type.
3.3.2 Connection Type: PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with
a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data
networks.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for instance, RADIUS).

Chapter 3 Connection Wizard
NBG5615 User’s Guide 31
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 NBG5615 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG5615 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.

3.3.3 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 NBG5615 supports one PPTP server connection at any given time.

Tutorials
9.1 Overview
This chapter provides tutorials for setting up your NBG5615.
•Set Up a Wireless Network with WPS
•Configure Wireless Security without WPS
•Using Multiple SSIDs on the NBG5615
•Automatically Connecting to a USB Printer
9.2 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 NBG5615 as the AP and NWD210N as the wireless client which connects to a notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter
or PCI card).
There are two WPS methods for creating a secure connection. This tutorial shows you how to do
both.
•Push Button Configuration ( PBC) - create a secure wireless network simply by pressing a
button. See Section 9.2.1 on page 73.This is the easier method.
•PI N Configuration - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the NBG5615’s interface. See Section 9.2.2 on page 74. This
is the more secure method, since one device can authenticate the other.
9.2.1 Push Button Configuration (PBC)
1Make sure that your NBG5615 is turned on. Make sure the W I FI button (at the back panel of the
NBG5615) is pushed in, and that the device is placed within range of your notebook.
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
W PS button)
4Log into NBG5615’s Web Configurator and press the Push Button in the Configuration >
Netw ork > W ireless LAN 2 .4 G > W PS Station screen.
Chapter 9 Tutorials
NBG5615 User’s Guide

Note: Your NBG5615 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 NBG5615 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 NBG5615 securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both NBG5615 and wireless client (the NWD210N in this example).
Figure 44 Example WPS Process: PBC Method
9.2.2 PIN Configuration
When you use the PIN configuration method, you need to use both NBG5615’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.

9.3.1 Configure Your Notebook
Note: We use the ZyXEL NWD2205 wireless adapter utility screens as an example for the
wireless client. The screens may vary for different models.
1The NBG5615 supports IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n wireless
clients. Make sure that your notebook or computer’s wireless adapter supports one of these
standards.
2Wireless adapters come with software sometimes called a “utility” that you install on your
computer. See your wireless adapter’s User’s Guide for information on how to do that.

weak or you have no connection, see the Troubleshooting section of this User’s Guide.
If your connection is successful, open your Internet browser and enter http://www.zyxel.com or the
URL of any other web site in the address bar. If you are able to access the web site, your wireless
connection is successfully configured.
9.4 Using Multiple SSIDs on the NBG5615
You can configure more than one SSID on a NBG5615. See Section 12.4 on page 118.
This allows you to configure multiple independent wireless networks on the NBG5615 as if there
were multiple APs (virtual APs). Each virtual AP has its own SSID, wireless security type and MAC
filtering settings. That is, each SSID on the NBG5615 represents a different access point/wireless
network to wireless clients in the network.
Clients can associate only with the SSIDs for which they have the correct security settings. Clients
using different SSIDs can access the Internet and the wired network behind the NBG5615 (such as
a printer).

For example, you may set up three wireless networks (A, B and C) in your office. A is for workers,
B is for guests and C is specific to a VoIP device in the meeting room.
9.4.1 Configuring Security Settings of Multiple SSIDs
The NBG5615 is in router mode by default.
This example shows you how to configure the SSIDs with the following parameters on your
NBG5615 (in router mode).
1Connect your computer to the LAN port of the NBG5615 using an Ethernet cable.
2The default IP address of the NBG5615 in router mode is “192.168.1.1”. In this case, your
computer must have an IP address in the range between “192.168.1.2” and “192.168.1.254”.
3Click Start > Run on your computer in Windows. Type “cmd” in the dialog box. Enter “ipconfig” to
show your computer’s IP address. If your computer’s IP address is not in the correct range then see
Appendix B on page 221 for information on changing your computer’s IP address.
4After you’ve set your computer’s IP address, open a web browser such as Internet Explorer and
type “http://192.168.1.1” as the web address in your web browser.

WAN
11.1 Overview
This chapter discusses the NBG5615’s W AN screens. Use these screens to configure your NBG5615
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 51 LAN and WAN
11.2 What You Can Do
•Use the I nternet Connection screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (Section 11.4 on page 97).
•Use the Advanced screen to enable multicasting, configure Windows networking and bridge
(Section 11.5 on page 104).
11.3 What You Need To Know
The information in this section can help you configure the screens for your WAN connection, as well
as enable/disable some advanced features of your NBG5615.
Chapter 11 WAN
NBG5615 User’s Guide
96
11.3.1 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 NBG5615, which makes it accessible from an outside
network. It is used by the NBG5615 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG5615 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 NBG5615 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 NBG5615’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 com puter's MAC address - I P 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.
Chapter 11 WAN
NBG5615 User’s Guide 97
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 52 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 NBG5615 supports both IGMP version 1
(I GMP-v1) and IGMP version 2 (I GMP- v2).
At start up, the NBG5615 queries all directly connected networks to gather group membership.
After that, the NBG5615 periodically updates this information. IP multicasting can be enabled/
disabled on the NBG5615 WAN interface in the Web Configurator (W AN). Select None to disable IP
multicasting on these interfaces.

NBG5615 User’s Guide 99
11.4.2 PPPoE Encapsulation
The NBG5615 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 NBG5615 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG5615 does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

Select None if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
WAN MAC Address The MAC address section allows users to configure the WAN port's MAC address by
either using the NBG5615’s MAC address, copying the MAC address from a computer on
your LAN or manually entering a MAC address.

CHAPTER 12
Wireless LAN
12.1 Overview
This chapter discusses how to configure the wireless network settings in your NBG5615. The
NBG5615 is able to function both 2.4GHz and 5GHz network at the same time. You can have
different wireless and wireless security settings for 2.4GHz and 5GHz wireless LANs. Click
Configuration > Netw ork > W ireless LAN 2.4G or W ireless LAN 5G to configure to do so.
See the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 57 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B are
called wireless clients. The wireless clients use the access point (AP) to interact with other devices
(such as the printer) or with the Internet. Your NBG5615 is the AP.
Chapter 12 Wireless LAN
NBG5615 User’s Guide
106
12.1.1 What You Can Do
•Use the General screen to turn the wireless connection on or off, set up wireless security
between the NBG5615 and the wireless clients, and make other basic configuration changes
(Section 12.2 on page 110).
•Use the More AP screen to set up multiple wireless networks on your NBG5615 (Section 12.4 on
page 118).
•Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the NBG5615 (Section 12.5 on page 121).
•Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section
12.6 on page 123).
•Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 12.7 on
page 123).
•Use the W PS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 12.8 on page 124).
•Use the W PS Station screen to add a wireless station using WPS (Section 12.9 on page 126).
•Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section
12.10 on page 126).
12.1.2 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.
Chapter 12 Wireless LAN
NBG5615 User’s Guide 107
MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is
usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or
00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s
Guide or other documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to
use the wireless network. If a wireless client is allowed to use the wireless network, it still has to
have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the
wireless network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized
wireless client. Then, they can use that MAC address to use the wireless network.
User Authentication
You can make every user log in to the wireless network before they can use it. This is called user
authentication. However, every wireless client in the wireless network has to support IEEE 802.1x
to do this.
For wireless networks, there are two typical places to store the user names and passwords for each
user.
• In the AP: this feature is called a local user database or a local database.
• In a RADIUS server: this is a server used in businesses more than in homes.
If your AP does not provide a local user database and if you do not have a RADIUS server, you
cannot set up user names and passwords for your users.
Unauthorized devices can still see the information that is sent in the wireless network, even if they
cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to
get a valid user name and password. Then, they can use that user name and password to use the
wireless network.
Local user databases also have an additional limitation that is explained in the next section.
Encryption
Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.
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 12 Wireless LAN
NBG5615 User’s Guide
108
The types of encryption you can choose depend on the type of user authentication. (See page 107
for information about this.)
For example, if the wireless network has a RADIUS server, you can choose W PA or W PA2 . If users
do not log in to the wireless network, you can choose no encryption, Static W EP, W PA- PSK, or
W PA2 -PSK.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. For example, suppose the AP does not have a local user database, and you do
not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network
has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA.
Therefore, you should set up Static W EP in the wireless network.
Note: It is recommended that wireless networks use W PA- PSK, W PA, or stronger
encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is
still possible for unauthorized devices to figure out the original information pretty
quickly.
Note: It is not possible to use W PA- PSK, W PA or stronger encryption with a local user
database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select W PA2 or W PA2 -PSK in your NBG5615, you can also select an option (W PA/
W PA-PSK Com patible) to support WPA/WPA-PSK as well. In this case, if some wireless clients
support WPA and some support WPA2, you should set up W PA2 -PSK or W PA2 (depending on the
type of wireless network login) and select the W PA/W PA-PSK Com patible option in the
NBG5615.
Many types of encryption use a key to protect the information in the wireless network. The longer
the key, the stronger the encryption. Every wireless client in the wireless network must have the
same key.
Guest WLAN
Guest WLAN allows you to set up a wireless network where users can access to Internet via the
NBG5615 (Z), but not other networks connected to the Z. In the following figure, a guest user can
access the Internet from the guest wireless network A via Z but not the home or company network
N.
Note: The home or company network N and Guest WLAN network are independent
networks.
Note: Only Router mode supports guest WLAN.

WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a wireless network with strong security, without having to configure
security settings manually. Depending on the devices in your network, you can either press a
button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification

Because not all devices support 40 MHz channels, select Auto 20 / 4 0MHz to allow the
NBG5615 to adjust the channel bandwidth automatically.
40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. The wireless clients must also support 40 MHz. It is often better to use the 20
MHz setting in a location where the environment hinders the wireless signal.
Select 20 MHz if you want to lessen radio interference with other wireless devices in your

connecting to it. Select Enable to turn on preauthentication in WAP2. Otherwise,
select Disable.
Authentication Server
IP Address Enter the IP address of the external authentication server in dotted decimal notation.
Port Number Enter the port number of the external authentication server.
You need not change this value unless your network administrator instructs you to do
so with additional information.
Shared Secret Enter a password (up to 127 alphanumeric characters) as the key to be shared
between the external authentication server and the NBG5615.
The key must be the same on the external authentication server and your NBG5615.
The key is not sent over the network.
Session Timeout The NBG5615 automatically disconnects a wireless client from the wireless and wired
networks after a period of inactivity. The wireless client needs to send the username
and password again before it can use the wireless and wired networks again. Some
wireless clients may prompt users for a username and password; other clients may
use saved login credentials. In either case, there is usually a short delay while the
wireless client logs in to the wireless network again.
Enter the time in seconds from 0 to 999999.

CHAPTER 13
LAN
13.1 Overview
This chapter describes how to configure LAN settings.
A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is a computer network limited to the immediate area, usually the same building or
floor of a building.
Figure 74 LAN Example
The LAN screens can help you configure a manage IP address, and partition your physical
network into logical networks.
13.2 What You Can Do
•Use the I P screen to change the IP address for your NBG5615 (Section 13.4 on page 130).
•Use the I P Alias screen to have the NBG5615 apply IP alias to create LAN subnets (Section 13.5
on page 131).
13.3 What You Need To Know
The actual physical connection determines whether the NBG5615 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 13 LAN
NBG5615 User’s Guide
130
Figure 75 LAN and WAN IP Addresses
The LAN parameters of the NBG5615 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.
13.3.1 IP Pool Setup
The NBG5615 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 NBG5615 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.
13.3.2 LAN TCP/IP
The NBG5615 has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.
13.3.3 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The NBG5615 supports three logical LAN interfaces via its single physical
Ethernet interface with the NBG5615 itself as the gateway for each LAN network.
