Note: Notes tell you other important information (for example, other things you may need to configure or helpful tips) or recommendations.

Syntax Conventions

•The NBG-419N may be referred to as the “NBG-419N”, the “device”, the “product” or the “system” in this User’s Guide.

•Product labels, screen names, field labels and field choices are all in bold font.

•A key stroke is denoted by square brackets and uppercase text, for example, [ENTER] means the “enter” or “return” key on your keyboard.

•“Enter” means for you to type one or more characters and then press the [ENTER] key. “Select” or “choose” means for you to use one of the predefined choices.

•A right angle bracket ( > ) within a screen name denotes a mouse click. For example, Maintenance > Log > Log Setting means you first click Maintenance in the navigation panel, then the Log sub menu and finally the Log Setting tab to get to that screen.

•Units of measurement may denote the “metric” value or the “scientific” value. For example, “k” for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000” or “1048576” and so on.

Getting to Know Your NBG-419N

1.1 Overview

This chapter introduces the main features and applications of the NBG-419N.

The NBG-419N 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. 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-419N:

•Wired. You can connect network devices via the Ethernet ports of the NBG419N so that they can communicate with each other and access the Internet.

•Wireless. Wireless clients can connect to the NBG-419N to access network resources.

•WAN. Connect to a broadband modem/router for Internet access.

Use any of the following methods to manage the NBG-419N.

•Web Configurator. This is recommended for everyday management of the NBG419N using a (supported) web browser.

•Wireless switch. You can use the built-in switch of the NBG-419N 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 ZyXEL Device.

1.4Good Habits for Managing the NBG-419N

Do the following things regularly to make the NBG-419N more secure and to manage the NBG-419N 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-419N to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG-419N. You could simply restore your last configuration.

Connection Wizard

2.1 Overview

This chapter provides information on the wizard setup screens in the Web Configurator.

The Web Configurator’s wizard setup helps you configure your device to access the Internet. Refer to your ISP for your Internet account information. Leave a field blank if you don’t have that information.

2.2 Accessing the Wizard

Launch your web browser and type "http://192.168.1.1" as the website address. Type "1234" (default) as the password and click Login.

Note: The Wizard appears when the NBG-419N is accessed for the first time or when you reset the NBG-419N to its default factory settings.

The Wizard screen opens. Choose your Language and click Connect to

Internet.

2.3 Connect to Internet

The NBG-419N offers five Internet connection types. They are Static IP, DHCP, PPPoE, PPTP or L2TP. The wizard attempts to detect which WAN connection type you are using.

Figure 4 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).

Figure 5 Internet Connection Type

Your NBG-419N detects the following Internet Connection type.

	CONNECTION	DESCRIPTION
	TYPE	DESCRIPTION
	TYPE
	Static IP	Select the Static IP if an administrator assigns the IP address of

		subnet mask.

	L2TP	Select the L2TP (Layer 2 Tunnel Protocol) if you are connecting to
		another device over another network (like the Internet or VPN).

2.3.1 Connection Type: DHCP

Choose DHCP as the Internet Connection Type when the WAN port is used as a regular Ethernet. Click Next.

2.3.2 Connection Type: Static IP

Choose Static IP as the Internet Connection Type if your ISP assigned an IP address for your Internet connection. Click Next.

The following table describes the labels in this screen.

IP Address	Enter the IP address provided by your ISP.

Subnet Mask	Enter the IP subnet mask in this field.

Default Gateway	Enter the gateway IP address in this field.

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-419N
	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.

2.3.3 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

Chapter 2 Connection Wizard

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-419N (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG-419N does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

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-419N supports one PPTP server connection at any given time.
