CHAPTER 1
Getting to Know Your ZyXEL
Device
This chapter introduces the main features and applications of the ZyXEL Device.
1.1 ZyXEL Device Overview
The ZyXEL Device is the ideal secure wireless firewall router for all data passing between the
Internet and your Local Area Network.
You can configure firewall and/or content filtering for secure Internet access. You can also use
media bandwidth management to efficiently manage traffic on your network. The Quality of
Service (QoS) features allow you to prioritize time-sensitive or highly important applications
such as VoIP.
The ZyXEL Device has an embedded mini-PCI module for 802.11g Wireless LAN
connectivity. The ZyXEL Device supports the IEEE 802.11b and g standards, so that either
IEEE 802.11b or IEEE 802.11g compatible clients can wirelessly access the ZyXEL Device or
the wired network behind it. the ZyXEL Device allows you to access wireless networks at
speeds of up to 108Mbps (with the Super G function enabled)
"Only use firmware for your ZyXEL Device’s specific model.
1.2 Applications for the ZyXEL Device
Here are some examples of what you can do with your ZyXEL Device.
1.2.1 Secure Broadband Internet Access
You can connect a cable modem, DSL or wireless modem to the ZyXEL Device for broadband
Internet access via an Ethernet or a wireless port on the modem. The ZyXEL Device
guarantees not only high speed Internet access, but secure internal network protection and
traffic management as well.

1.2.1.1 Wireless LAN Application
Add a wireless LAN to your existing network without expensive network cables. Wireless
stations can move freely anywhere in the coverage area and use resources on the wired
network.
Figure 2 WLAN Application Example
1.3 Ways to Manage the ZyXEL Device
Use any of the following methods to manage the ZyXEL Device.
• 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. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
1.4 Good Habits for Managing the ZyXEL Device
Do the following things regularly to make the ZyXEL Device more secure and to manage the
ZyXEL Device 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.
Chapter 1 Getting to Know Your ZyXEL Device
ZyXEL NBG-334SH User’s Guide 31
• 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
Wireless Tutorial
This chapter gives you examples of how to set up an access point and wireless client for
wireless communication using the following parameters. The wireless clients can access the
Internet through an AP wirelessly.
2.1 Example Parameters
An access point (AP) or wireless router is referred to as an “AP” and a computer with a
wireless network card or USB/PCI adapter is referred to as a “wireless client” here.
We use the M-302 utility screens as an example for the wireless client. The screens may vary
for different models.
2.2 Configuring the AP
Flow the steps below to configure the wireless settings on your AP.
1Open the Wireless LAN > General screen in the AP’s web configurator.

2.3 Configuring the Wireless Client
This section describes how to connect the wireless client to a network.
Chapter 2 Wireless Tutorial
ZyXEL NBG-334SH User’s Guide

2.3.1 Connecting to a Wireless LAN
The following sections show you how to join a wireless network using the ZyXEL utility, as in
the following diagram. The wireless client is labeled C and the access point is labeled AP.
There are three ways to connect the client to an access point.
• Configure nothing and leave the wireless client to automatically scan for and connect to
any available network that has no wireless security configured.
• Manually connect to a network.
• Configure a profile to have the wireless client automatically connect to a specific network
or peer computer.
This example illustrates how to manually connect your wireless client to an access point (AP)
which is configured for WPA-PSK security and connected to the Internet. Before you connect
to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared
key. In this example, the SSID is “SSID_Example3” and the pre-shared key is
“ThisismyWPA-PSKpre-sharedkey”.
After you install the ZyXEL utility and then insert the wireless client, follow the steps below
to connect to a network using the Site Survey screen.
1Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.
2The wireless client automatically searches for available wireless networks. Click Scan if
you want to search again. If no entry displays in the Available Network List, that means
there is no wireless network available within range. Make sure the AP or peer computer
is turned on or move the wireless client closer to the AP or peer computer.
3When you try to connect to an AP with security configured, a window will pop up
prompting you to specify the security settings. Enter the pre-shared key and leave the
encryption type at the default setting.
Use the Next button to move on to the next screen. You can use the Back button at any
time to return to the previous screen, or the Exit button to return to the Site Survey
screen.

5The ZyXEL utility returns to the Link Info screen while it connects to the wireless
network using your settings. When the wireless link is established, the ZyXEL utility
icon in the system tray turns green and the Link Info screen displays details of the active
connection. Check the network information in the Link Info screen to verify that you
have successfully connected to the selected network. If the wireless client is not
connected to a network, the fields in this screen remain blank.
Figure 9 ZyXEL Utility: Link Info
6Open 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.

If you cannot access the web site, try changing the encryption type in the Security
Settings screen, check the Troubleshooting section of this User's Guide or contact your
network administrator.
2.3.2 Creating and Using a Profile
A profile lets you automatically connect to the same wireless network every time you use the
wireless client. You can also configure different profiles for different networks, for example if
you connect a notebook computer to wireless networks at home and at work.
This example illustrates how to set up a profile and connect the wireless client to an access
point configured for WPA-PSK security. In this example, the SSID is “SSID_Example3”, the
profile name is “PN_Example3” and the pre-shared key is “ThisismyWPA-PSKpre-
sharedkey”. You have chosen the profile name “PN_Example3”.
1Open the ZyXEL utility and click the Profile tab to open the screen shown next. Click
Add to configure a new profile.
Figure 10 ZyXEL Utility: Profile
2The Add New Profile screen appears. The wireless client automatically searches for
available wireless networks, which are displayed in the Scan Info box. Click on Scan if
you want to search again. You can also configure your profile for a wireless network that
is not in the list.
Figure 11 ZyXEL Utility: Add New Profile
3Give the profile a descriptive name (of up to 32 printable ASCII characters). Select
Infrastructure and either manually enter or select the AP's SSID in the Scan Info table
and click Select.
Chapter 2 Wireless Tutorial

4.4.2 PPPoE Connection
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).
Table 12 Wizard Step 3: ISP Parameters
CONNECTION TYPE DESCRIPTION
Ethernet Select the Ethernet option when the WAN port is used as a regular Ethernet.
PPPoE Select the PPP over Ethernet option for a dial-up connection. If your ISP
gave you a an IP address and/or subnet mask, then select PPTP.
PPTP Select the PPTP option for a dial-up connection.
Chapter 4 Connection Wizard
ZyXEL NBG-334SH User’s Guide
62
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 ZyXEL Device (rather than individual computers),
the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device
does that part of the task. Furthermore, with NAT, all of the LAN's computers will have
Internet access.
Refer to the appendix for more information on PPPoE.
Figure 33 Wizard Step 3: PPPoE Connection
The following table describes the labels in this screen.
4.4.3 PPTP Connection
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.

4.4.5 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated
from the Internet, for instance, only between your two branch offices, you can assign any IP
addresses to the hosts without problems. However, the Internet Assigned Numbers Authority
(IANA) has reserved the following three blocks of IP addresses specifically for private
networks.

ZyXEL NBG-334SH User’s Guide 65
You can obtain your IP address from the IANA, from an ISP or have it assigned by a private
network. If you belong to a small organization and your Internet access is through an ISP, the
ISP can provide you with the Internet addresses for your local networks. On the other hand, if
you are part of a much larger organization, you should consult your network administrator for
the appropriate IP addresses.
"Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.
4.4.6 IP Address and Subnet Mask
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 ZyXEL Device, 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 ZyXEL Device
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 ZyXEL Device unless you are
instructed to do otherwise.
4.4.7 DNS Server Address Assignment
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.
The ZyXEL Device 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, enter them in the DNS
Server fields in the Wizard and/or WAN > Internet Connection screen.
Chapter 4 Connection Wizard
ZyXEL NBG-334SH User’s Guide

2If the ISP did not give you DNS server information, leave the DNS Server fields set to
0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN > Internet
Connection screen for the ISP to dynamically assign the DNS server IP addresses.
4.4.8 WAN IP and DNS Server Address Assignment
The following wizard screen allows you to assign a fixed WAN IP address and DNS server
addresses.

System DNS Server Address Assignment (if applicable)
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 ZyXEL Device uses a system DNS server (in the order you
specify here) to resolve domain names for DDNS and the time server.

CHAPTER 5
Wireless LAN
This chapter discusses how to configure the wireless network settings in your ZyXEL Device.
See the appendices for more detailed information about wireless networks.
5.1 Wireless Network Overview
The following figure provides an example of a wireless network.
Figure 41 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 ZyXEL Device is the AP.
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.
Chapter 5 Wireless LAN
ZyXEL NBG-334SH User’s Guide
74
• 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.
5.2 Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the
wireless network.
5.2.1 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.
5.2.2 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.
5.2.3 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.
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 5 Wireless LAN
ZyXEL NBG-334SH User’s Guide 75
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.
5.2.4 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.
The types of encryption you can choose depend on the type of user authentication. (See
Section 5.2.3 on page 74 for information about this.)
For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2.
If users do not log in to the wireless network, you can choose no encryption, Static WEP,
WPA-PSK, or WPA2-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 WEP in the wireless network.
"It is recommended that wireless networks use WPA-PSK, WPA, 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.
It is not possible to use WPA-PSK, WPA 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.
Table 21 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
Weakest No Security WPA
Static WEP
WPA-PSK
Strongest WPA2-PSK WPA2
Chapter 5 Wireless LAN
ZyXEL NBG-334SH User’s Guide
76
When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option
(WPA Compatible) to support WPA as well. In this case, if some wireless clients support
WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the
type of wireless network login) and select the WPA Compatible option in the ZyXEL Device.
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.
5.3 Quality of Service
This section discusses the Quality of Service (QoS) features available on the ZyXEL Device.
5.3.1 WMM QoS
WMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless
networks. It controls WLAN transmission priority on packets to be transmitted over the
wireless network.
WMM QoS prioritizes wireless traffic according to delivery requirements. WMM QoS is a
part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.
On APs without WMM QoS, all traffic streams are given the same access priority to the
wireless network. If the introduction of another traffic stream creates a data transmission
demand that exceeds the current network capacity, then the new traffic stream reduces the
throughput of the other traffic streams.
The ZyXEL Device uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q
tag or DSCP information in each packet’s header. The ZyXEL Device automatically
determines the priority to use for an individual traffic stream. This prevents reductions in data
transmission for applications that are sensitive to latency (delay) and jitter (variations in
delay).
5.3.1.1 WMM QoS Priorities
The following table describes the WMM QoS priority levels that the ZyXEL Device uses.
Table 22 WMM QoS Priorities
PRIORITY LEVEL DESCRIPTION
voice
(WMM_VOICE)
Typically used for traffic that is especially sensitive to jitter. Use this priority
to reduce latency for improved voice quality.
video
(WMM_VIDEO)
Typically used for traffic which has some tolerance for jitter but needs to be
prioritized over other data traffic.
best effort
(WMM_BEST_EFFORT)
Typically used for traffic from applications or devices that lack QoS
capabilities. Use best effort priority for traffic that is less sensitive to latency,
but is affected by long delays, such as Internet surfing.
background
(WMM_BACKGROUND)
This is typically used for non-critical traffic such as bulk transfers and print
jobs that are allowed but that should not affect other applications and users.
Use background priority for applications that do not have strict latency and
throughput requirements.

CHAPTER 6
WAN
This chapter describes how to configure WAN settings.
6.1 WAN Overview
See the chapter about the connection wizard for more information on the fields in the WAN
screens.
6.2 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 computer's MAC address - IP 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 the rom file (ZyNOS configuration file). It will not change unless
you change the setting or upload a different ROM file. It is recommended that you clone the
MAC address prior to hooking up the WAN Port.
6.3 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.
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. IGMP version 2 (RFC
2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between IGMP
version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is
used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address
224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address
224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts
(including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP.
The address 224.0.0.2 is assigned to the multicast routers group.

The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-
v2). At start up, the ZyXEL Device queries all directly connected networks to gather group
membership. After that, the ZyXEL Device periodically updates this information. IP
multicasting can be enabled/disabled on the ZyXEL Device LAN and/or WAN interfaces in
the web configurator (LAN; WA N ). Select None to disable IP multicasting on these
interfaces.

6.4.2 PPPoE Encapsulation
The ZyXEL Device 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 ZyXEL Device (rather than individual computers),
the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device
does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have
access.
This screen displays when you select PPPoE encapsulation.

CHAPTER 7
LAN
This chapter describes how to configure LAN settings.
7.1 LAN Overview
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.
7.1.1 IP Pool Setup
The ZyXEL Device 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
ZyXEL Device 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.
7.1.2 System DNS Servers
Refer to the IP address and subnet mask section in the Connection Wizard chapter.
7.2 LAN TCP/IP
The ZyXEL Device has built-in DHCP server capability that assigns IP addresses and DNS
servers to systems that support DHCP client capability.
7.2.1 Factory LAN Defaults
The LAN parameters of the ZyXEL Device 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.
Chapter 7 LAN

7.2.2 IP Address and Subnet Mask
Refer to the IP address and subnet mask section in the Connection Wizard chapter for this
information.
7.2.3 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.
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. IGMP version 2 (RFC
2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between IGMP
version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is
used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address
224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address
224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts
(including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP.
The address 224.0.0.2 is assigned to the multicast routers group.
The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-
v2). At start up, the ZyXEL Device queries all directly connected networks to gather group
membership. After that, the ZyXEL Device periodically updates this information. IP
multicasting can be enabled/disabled on the ZyXEL Device LAN and/or WAN interfaces in
the web configurator (LAN; WA N ). Select None to disable IP multicasting on these
interfaces.
7.2.4 Any IP
Traditionally, you must set the IP addresses and the subnet masks of a computer and the
ZyXEL Device to be in the same subnet to allow the computer to access the Internet (through
the ZyXEL Device). In cases where your computer is required to use a static IP address in
another network, you may need to manually configure the network settings of the computer
every time you want to access the Internet via the ZyXEL Device.
With the Any IP feature and NAT enabled, the ZyXEL Device allows a computer to access the
Internet without changing the network settings (such as IP address and subnet mask) of the
computer, when the IP addresses of the computer and the ZyXEL Device are not in the same
subnet. Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply
connect the computer to the ZyXEL Device and access the Internet.
The following figure depicts a scenario where a computer is set to use a static private IP
address in the corporate environment. In a residential house where a ZyXEL Device is
installed, you can still use the computer to access the Internet without changing the network
settings, even when the IP addresses of the computer and the ZyXEL Device are not in the
same subnet.
