CHAPTER 1
Getting to Know Your ZyXEL
Device
This chapter introduces the main features and applications of the ZyXEL Device.

1.1 Overview

The ZyXEL Device is a high-security 3G router with wireless capability.
Access the Internet with the 3G connection from any location with 3G coverage, with the option of using a wired WAN connection at the same time.
Enhance network security by adding a De-Militarized Zone (DMZ) to your network. This separates devices that are publicly accessible (and less secure) from your LAN.
Set up a local network with the four LAN ports and set up a wireless network with IEEE
802.11b or IEEE 802.11g compatible wireless devices. The ZyXEL Device provides the option to easily move devices from your LAN or wireless network to the DMZ.
The ZyXEL Device also provides NAT, port forwarding, DHCP server and many other powerful features.
The NBG410W3G and NBG412W3G offer similar features. However, the NBG410W3G also supports an internal 3G interface.
See Chapter 22 on page 345 for a complete list of features for both devices.

1.2 Applications for the ZyXEL Device

Here are some examples of what you can do with your ZyXEL Device.

1.2.1 3G WAN Application

With an activated, correctly inserted 3G SIM card you can use the ZyXEL Device to wirelessly access the Internet via a 3G base station. See Section 6.9 on page 126 for more information about 3G.
With both the primary WAN (physical WAN port) and 3G connections enabled, you can set one of the WAN connections as a backup.
NBG410W3G Series User’s Guide
35
Chapter 1 Getting to Know Your ZyXEL Device
Figure 1 3G WAN Application

1.2.2 Secure Broadband Internet Access via Cable or DSL Modem

For Internet access, connect the WAN Ethernet port to your existing Internet access gateway (company network, or your cable or DSL modem for example). Connect computers or servers to the LAN or DMZ ports for shared Internet access.
The ZyXEL Device guarantees not only high speed Internet access, but secure internal network protection and traffic management as well.
Figure 2 Secure Internet Access via Cable or DSL Modem

1.3 Ways to Manage the ZyXEL Device

Use any of the following methods to manage the ZyXEL Device.
36
• Web Configurator. This is recommended for everyday management of the ZyXEL Device using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service engineers.
• FTP for firmware upgrades and configuration backup/restore.
NBG410W3G Series User’s Guide
Chapter 1 Getting to Know Your ZyXEL Device

1.4 Configuring Your ZyXEL Device’s Security Features

Your ZyXEL Device comes with a variety of security features. This section summarizes these features and provides links to sections in the User’s Guide to configure security settings on your ZyXEL Device. Follow the suggestions below to improve security on your ZyXEL Device and network.

1.4.1 Control Access to Your Device

Ensure only people with permission can access your ZyXEL Device.
• Control physical access by locating devices in secure areas, such as locked rooms. Most ZyXEL Devices have a reset button. If an unauthorized person has access to the reset button, they can then reset the device’s password to its default password, log in and reconfigure its settings.
• Change any default passwords on the ZyXEL Device, such as the password used for accessing the ZyXEL Device’s web configurator (if it has a web configurator). Use a password with a combination of letters and numbers and change your password regularly. Write down the password and put it in a safe place.
• Avoid setting a long timeout period before the ZyXEL Device’s web configurator automatically times out. A short timeout reduces the risk of unauthorized person accessing the web configurator while it is left idle.
See Chapter 20 on page 325 for instructions on changing your password and setting the timeout period.
• Configure remote management to control who can manage your ZyXEL Device. See
Section 15.1 on page 259 for more information. If you enable remote management, ensure
you have enabled remote management only on the IP addresses, services or interfaces you intended and that other remote management settings are disabled.

1.4.2 Wireless Security

Wireless devices are especially vulnerable to attack. If your ZyXEL Device has a wireless function, take the following measures to improve wireless security.
• Enable wireless security on your ZyXEL Device. Choose the most secure encryption method that all devices on your network support. If you have a RADIUS server, enable IEEE 802.1x or WPA(2) user identification on your network so users must log in. This method is more common in business environments.
• Hide your wireless network name (SSID). The SSID can be regularly broadcast and unauthorized users may use this information to access your network.
• Enable the MAC filter to allow only trusted users to access your wireless network or deny unwanted users access based on their MAC address.
See Section 8.2 on page 148 for directions on these wireless security measures.

1.4.3 Firewall

See Section 9.1 on page 167 for more information on the following security measures
• Ensure the firewall is turned on. Traffic initiated from your WAN is blocked by default.
NBG410W3G Series User’s Guide
37
Chapter 1 Getting to Know Your ZyXEL Device
• Set the firewall to block ICMP requests.
• Enable do not respond to requests for unauthorized services.
• If you have a backup gateway (for example, backup Internet access) on your network, disable the Bypass Triangle Routes feature and enable IP Alias to put your backup gateway on a different subnet.
• Avoid raising the maximum number of NAT sessions per host unnecessarily as it increases the possibility of unauthorized connections, such as connections caused by a computer virus.

1.4.4 NAT

• Enable NAT (Network Address Translation) to make devices on your network “invisible” to those outside your network (unless you configure port-forwarding rules for them).
• Applications such as games or file-sharing can be configured so they are visible from other networks by using port-forwarding. Ensure only applications you want are configured to port-forward.
See Section 12.1 on page 225 for instructions on these measures.

1.4.5 UPnP

• Disable UPnP (Universal Plug and Play) unless you specifically want applications (for example, games or file-sharing applications) on your network to pass through your firewall unchecked.
See Section 16.1 on page 281 for instructions on this measure.

1.5 Maintaining Your ZyXEL Device

Do the following things regularly to keep your ZyXEL Device running.
• Check the ZyXEL website (www.zyxel.com.tw) regularly for new firmware for your ZyXEL Device.
" Ensure you download the correct firmware for your model.
• 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 ZyXEL Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the ZyXEL Device. You could simply restore your last configuration.

Chapter 2 Introducing the Web Configurator
" The management session automatically times out when the time period set in
the Administrator Inactivity Timer field expires (default five minutes). Simply log back into the ZyXEL Device if this happens to you.

2.3 Resetting the ZyXEL Device

If you forget your password or cannot access the web configurator, you will need to reload the factory-default configuration file or use the RESET button on the back of the ZyXEL Device. Uploading this configuration file replaces the current configuration file with the factory­default configuration file. This means that you will lose all configurations that you had previously and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and flow control set to none. The password will be reset to 1234, also.

2.3.1 Procedure To Use The Reset Button

Make sure the POWER LED is on (not blinking) before you begin this procedure.
1 Press the RESET button for ten seconds, and then release it. If the POWER LED begins
to blink, the defaults have been restored and the ZyXEL Device restarts. Otherwise, go to step 2.
2 Turn the ZyXEL Device off. 3 While pressing the RESET button, turn the ZyXEL Device on. 4 Continue to hold the RESET button. The POWER LED will begin to blink and flicker
very quickly after about 20 seconds. This indicates that the defaults have been restored and the ZyXEL Device is now restarting.
5 Release the RESET button and wait for the ZyXEL Device to finish restarting.

2.3.2 Uploading a Configuration File Via Console Port

1 Download the default configuration file from the ZyXEL FTP site, unzip it and save it in
a folder.
2 Turn off the ZyXEL Device, begin a terminal emulation software session and turn on the
ZyXEL Device again. When you see the message "Press Any key to enter Debug Mode within 3 seconds", press any key to enter debug mode.
3 Enter "y" at the prompt below to go into debug mode. 4 Enter "atlc" after "Enter Debug Mode" message. 5 Wait for "Starting XMODEM upload" message before activating Xmodem upload on
your terminal. This is an example Xmodem configuration upload using HyperTerminal.

LABEL DESCRIPTION
Status For the LAN and DMZ ports, this displays the port speed and duplex setting.
Ethernet port connections can be in half-duplex or full-duplex mode. Full-duplex refers to a device's ability to send and receive simultaneously, while half-duplex indicates that traffic can flow in only one direction at a time. The Ethernet port must use the same speed or duplex mode setting as the peer Ethernet port in order to connect.
For the WAN 1 port, it displays the port speed and duplex setting if you’re using Ethernet encapsulation or the remote node name for a PPP connection and Down (line is down or not connected), Idle (line (ppp) idle), Dial (starting to trigger a call) or Drop (dropping a call) if you’re using PPPoE encapsulation.
For the WAN 2 interface, it displays Connected when the 3G connection is up, Connecting when the 3G card is trying to connect to a network but has not received a response from the base station, Ready to Connect when the 3G connection is idle, Initializing when the ZyXEL Device is configuring the 3G card with AT commands, Disconnecting when the ZyXEL Device is dropping the 3G connection or Down when the 3G connection is down.
IP/Netmask This shows the port’s IP address and subnet mask.
IP Assignment For the WAN, if the ZyXEL Device gets its IP address automatically from an ISP,
this displays DHCP client when you’re using Ethernet encapsulation and IPCP Client when you’re using PPPoE or PPTP encapsulation. Static displays if the WAN port is using a manually entered static (fixed) IP address.
For the LAN or DMZ, DHCP server displays when the ZyXEL Device is set to automatically give IP address information to the computers connected to the LAN. DHCP relay displays when the ZyXEL Device is set to forward IP address assignment requests to another DHCP server. Static displays if the LAN port is using a manually entered static (fixed) IP address. In this case, you must have another DHCP server on your LAN, or else the computers must be manually configured.
Renew If you are using Ethernet encapsulation and the WAN port is configured to get the
IP address automatically from the ISP, click Renew to release the WAN port’s dynamically assigned IP address and get the IP address afresh. Click Dial to dial up the PPTP, PPPoE or 3G WAN connection. Click Drop to disconnect the PPTP, PPPoE or 3G WAN connection.

Tutorials

This section describes how to do the following.
1 Set up a DMZ (De-Militarized Zone). 2 Use an H.323 VoIP phone on your LAN. 3 Use NAT (Network Address Translation) with multiple public IP addresses. 4 Allow multiple game players to connect to the same server.

4.1 DMZ Overview

The DMZ is a separate network for devices that provide services to users on the Internet. Devices such as a web or e-mail server are more prone to security threats as they are more visible from the Internet and more frequently accessed than devices on your LAN. By placing such devices on a DMZ, you can better restrict access to the devices on your LAN.
The diagram shows servers on the DMZ which are open to public access but protected by the ZyXEL Device’s firewall. Devices which require greater security are located on the LAN.
Figure 18 DMZ Overview
DMZ
LAN
In this situation a file server is located in the DMZ. The file server is available for public access from the Internet and also from computers located on the LAN.
Internet
You can use either public or private IP addresses for your DMZ, however the DMZ must be on a different subnet or network from the LAN.
NBG410W3G Series User’s Guide

Chapter 4 Tutorials

4.2 DMZ Setup Example

In this example the DMZ uses private IP addresses and the default subnet mask of
255.255.255.0. (See Appendix C on page 377 for information on subnetting.) You can also use a static public IP address for your file server.

4.3 Firewall Rule Setup

Your ZyXEL Device’s firewall default settings provide network security by allowing traffic from the WAN to your DMZ, and blocking traffic from the DMZ to the LAN. However, you can further enhance network security by defining firewall rules specifically for traffic from the WA N t o th e D MZ .
NBG410W3G Series User’s Guide
69
Chapter 4 Tutorials
You need to define two rules - one to drop all traffic from the WAN to the DMZ, the other to permit HTTP and FTP traffic from the WAN to the DMZ. This ensures that only HTTP and FTP traffic from the WAN to the DMZ is permitted and all other traffic is blocked.
If you have not already done so, define a static IP address for the file server (see step 1 on
page 69 for instructions).
1 Click SECURITY > Firewall > Rule Summary to display the Rule Summary screen.

4.5.3 Public IP Address Mapping

To have the local computers and servers use specific WAN IP addresses, you need to map static public IP addresses to them.
" The one-to-one NAT address mapping rules are for both incoming and
outgoing connections. The ZyXEL Device forwards traffic that is initiated from either the LAN or the WAN to the destination IP address.
" The many-to-one or many-to-many NAT address mapping rules are for
outgoing connections only. That means only traffic initiated from the LAN or returned packets are allowed to go through the ZyXEL Device.
In this example, you create two one-to-one rules to map the internal web server (192.168.1.12) and mail server (192.168.1.13) to different static public IP addresses. The many-to-one rule maps a public IP address (1.2.3.4, that is, the ZyXEL Device’s WAN 1 IP address) to outgoing LAN traffic. It allows other local computers on the same subnet as the ZyXEL Device’s LAN IP address to use this IP address to access the Internet.

4.5.6 Testing the Connections

1 Open the web browser on one of the local computers and enter any web site’s URL in the
address bar. If you can access the web site, your WAN 1 connection and NAT address mapping are configured successfully. If you cannot access it, make sure you entered the correct information in the WAN and NAT Address Mapping screens. Also check that the Internet account is active and the computer’s IP address is in the same subnet as the ZyXEL Device.
2 Open your web browser and try accessing the web server (1.2.3.5) from the outside
network. If you cannot access the web server, make sure the NAT address mapping rule is configured correctly and there is a firewall rule to allow HTTP traffic from the WAN to the web server.
3 Try accessing the FTP server (1.2.3.4) from the outside network to send or retrieve a file.
If you cannot access the FTP server, make sure the NAT port forwarding rule is active and there is a firewall rule to allow FTP traffic from the WAN to FTP server.

4.6 Using NAT with Multiple Game Players

If two users (behind the ZyXEL Device) want to connect to the same server to play online games at the same time, but the server does not allow more than one login from the same IP address, you can configure a many-to-many rule instead of a many-to-one rule.
In this example, you have four static IP addresses (1.2.3.4 to 1.2.3.7) from your ISP. After you set up your WAN connection (see Section 4.5.2 on page 78), use the NAT > Address Mapping screen to map the third and forth public IP addresses to the mail server (192.168.1.12) and web server (192.168.1.13) respectively. The first and second public IP addresses are mapped to other outgoing LAN traffic. See Section 4.5.3 on page 82 for more information about IP address mapping.
When you finish configuration, the screen looks as shown.
