CHAPTER 1

Getting To Know Your ZY XEL

DEVICE

This chapter describes the key features and applications of your ZyXEL Device.

1.1 Introducing the ZyXEL Device

The ZyXEL Device is an ADSL2+ gateway that allows super-fast, secure Internet access over
analog (POTS) or digital (ISDN) telephone lines (depending on your model).

In the ZyXEL Device product name, “H” denotes an integrated 4-port switch (hub) and “W”
denotes an included wireless LAN card that provides wireless connectivity.

Models ending in “1”, for example P-660HW-D1, denote a device that works over the analog
telephone system, POTS (Plain Old Telephone Service). Models ending in “3” denote a device
that works over ISDN (Integrated Services Digital Network). Models ending in “7” denote a
device that works over T-ISDN (UR-2).

Note: Only use firmware for your ZyXEL Device’s specific model. Refer to the label on

the bottom of your ZyXEL Device.

The DSL RJ-11 (ADSL over POTS models) or RJ-45 (ADSL over ISDN models) connects to
your ADSL-enabled telephone line. The ZyXEL Device is compatible with the ADSL/
ADSL2/ADSL2+ standards.

Chapter 1 Getting To Know Your ZyXEL Device 34

P-660H/HW-D Series User’s Guide

1.2 Features

High Speed Internet Access

The ZyXEL Device is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks. The ZyXEL Device is compatible with the ADSL/ADSL2/
ADSL2+ standards. Maximum data rates attainable for each standard are shown in the next
table.

Table 1 ADSL Standards

DATA RATE STANDARD UPSTREAM DOWNSTREAM

ADSL

ADSL2

ADSL2+

832 kbps 8Mbps

3.5Mbps 12Mbps

3.5Mbps 24Mbps

Note: If your ZyXEL Device does not support Annex M, the maximum ADSL2/2+

upstream data rate is 1.2 Mbps. ZyXEL Devices which work over ISDN do not
support Annex M.

The standard your ISP supports determines the maximum upstream and

downstream speeds attainable. Actual speeds attained also depend on the
distance from your ISP, line quality, etc.

Zero Configuration Internet Access

Once you connect and turn on the ZyXEL Device, it automatically detects the Internet
connection settings (such as the VCI/VPI numbers and the encapsulation method) from the
ISP and makes the necessary configuration changes. In cases where additional account
information (such as an Internet account user name and password) is required or the ZyXEL
Device cannot connect to the ISP, you will be redirected to web screen(s) for information input
or troubleshooting.

Any IP

The Any IP feature allows a computer to access the Internet and the ZyXEL Device 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.

Firewall

The ZyXEL Device is a stateful inspection firewall with DoS (Denial of Service) protection.
By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The ZyXEL Device firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.

35 Chapter 1 Getting To Know Your ZyXEL Device

P-660H/HW-D Series User’s Guide

Content Filtering

Content filtering allows you to block access to forbidden Internet web sites, schedule when the
ZyXEL Device should perform the filtering and give trusted LAN IP addresses unfiltered
Internet access.

Traffic Redirect

Traffic redirect forwards WAN traffic to a backup gateway when the ZyXEL Device cannot
connect to the Internet, thus acting as an auxiliary if your regular WAN connection fails.

Media Bandwidth Management

ZyXEL’s Media Bandwidth Management allows you to specify bandwidth classes based on an
application and/or subnet. You can allocate specific amounts of bandwidth capacity
(bandwidth budgets) to different bandwidth classes.

Universal Plug and Play (UPnP)

Using the standard TCP/IP protocol, the ZyXEL Device and other UPnP enabled devices can
dynamically join a network, obtain an IP address and convey its capabilities to other devices
on the network.

PPPoE (RFC2516)

PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your
ISP to use their existing network configuration with newer broadband technologies such as
ADSL. The PPPoE driver on the ZyXEL Device is transparent to the computers on the LAN,
which see only Ethernet and are not aware of PPPoE thus saving you from having to manage
PPPoE clients on individual computers. The ZyXEL Device also includes PPPoE idle time-out
(the PPPoE connection terminates after a period of no traffic that you configure) and PPPoE
Dial-on-Demand (the PPPoE connection is brought up only when an Internet access request is
made).

Network Address Translation (NAT)

Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).

Dynamic DNS Support

With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address,
allowing the host to be more easily accessible from various locations on the Internet. You must
register for this service with a Dynamic DNS service provider.

Chapter 1 Getting To Know Your ZyXEL Device 36

P-660H/HW-D Series User’s Guide

DHCP

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The ZyXEL
Device has built-in DHCP server capability enabled by default. It can assign IP addresses, an
IP default gateway and DNS servers to DHCP clients. The ZyXEL Device can now also act as
a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual
real DHCP server to the clients.

IP Alias

IP Alias allows you to partition a physical network into logical networks over the same
Ethernet interface. The ZyXEL Device supports three logical LAN interfaces via its single
physical Ethernet interface with the ZyXEL Device itself as the gateway for each LAN
network.

TR-069 Compliance

TR-069 is a protocol that defines how your P-660H-D can be managed via a management
server such as ZyXEL’s Vantage CNM Access. The management server can securely manage
and update configuration changes in the P-660H-Ds.

Housing

Your ZyXEL Device's compact and ventilated housing minimizes space requirements making
it easy to position anywhere in your busy office.

4-port Switch

A combination of switch and router makes your ZyXEL Device a cost-effective and viable
network solution. You can connect up to four computers to the ZyXEL Device without the
cost of a hub. Use a hub to add more than four computers to your LAN.

1.2.1 Wireless Features (P-660HW-D Only)

Wireless LAN

The ZyXEL Device supports the IEEE 802.11g standard, which is fully compatible with the
IEEE 802.11b standard, meaning that you can have both IEEE 802.11b and IEEE 802.11g
wireless clients in the same wireless network.

Note: The ZyXEL Device may be prone to RF (Radio Frequency) interference from

other 2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth
enabled devices, and other wireless LANs.

37 Chapter 1 Getting To Know Your ZyXEL Device

P-660H/HW-D Series User’s Guide

Wi-Fi Protected Access

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification standard.
Key differences between WPA and WEP are user authentication and improved data
encryption.

WPA2

WPA 2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption,
authentication and key management than WPA.

Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol
(TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also
uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining
Message authentication code Protocol (CCMP) to offer stronger encryption.

Antenna

The ZyXEL Device is equipped with one 3dBi fixed antenna to provide clear radio signal
between the wireless stations and the access points.

WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network to help keep network communications private.

Output Power Management

Output power management is the ability to set the level of output power.

There may be interference or difficulty with channel assignment when there is a high density
of APs within a coverage area. In this case you can lower the output power of each access
point, thus enabling you to place access points closer together.

Wireless LAN MAC Address Filtering

Your ZyXEL Device can check the MAC addresses of wireless stations against a list of
allowed or denied MAC addresses.

1.3 Applications for the ZyXEL Device

Here are some example uses for which the ZyXEL Device is well suited.

Chapter 1 Getting To Know Your ZyXEL Device 38

P-660H/HW-D Series User’s Guide

1.3.1 Protected Internet Access

The ZyXEL Device is the ideal high-speed Internet access solution. It is compatible with all
major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers and supports
the ADSL standards as shown in Table 1 on page 35. In addition, the ZyXEL Device with the
wireless features allows wireless clients access to your network resources.

The ZyXEL Device provides protection from attacks by Internet hackers. By default, the
firewall blocks all incoming traffic from the WAN. The firewall supports TCP/UDP
inspection and DoS (Denial of Services) detection and prevention, as well as real time alerts,
reports and logs.

Figure 1 Protected Internet Access Applications

1.3.2 LAN to LAN Application

You can use the ZyXEL Device to connect two geographically dispersed networks over the
ADSL line. A typical LAN-to-LAN application example is shown as follows.

Bandwidth Management Wizard

This chapter shows you how to configure basic bandwidth management using the wizard
screens.

4.1 Introduction

Bandwidth management allows you to control the amount of bandwidth going out through the
ZyXEL Device’s WAN port and prioritize the distribution of the bandwidth according to
service bandwidth requirements. This helps keep one service from using all of the available
bandwidth and shutting out other users.

CHAPTER 5

WAN Setup

5.1.1.1 ENET ENCAP

The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the
IP network protocol. IP packets are routed between the Ethernet interface and the WAN
interface and then formatted so that they can be understood in a bridged environment. For
instance, it encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP
requires that you specify a gateway IP address in the ENET ENCAP Gateway field in the
second wizard screen. You can get this information from your ISP.

5.1.1.2 PPP over Ethernet

PPPoE (Point-to-Point Protocol over Ethernet) provides access control and billing
functionality in a manner similar to dial-up services using PPP. PPPoE is an IETF standard
(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem
(DSL, cable, wireless, etc.) connection.

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.

5.1.1.3 PPPoA

PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA
connection functions like a dial-up Internet connection. The ZyXEL Device encapsulates the
PPP session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual
Circuit) to the Internet Service Provider’s (ISP) DSLAM (digital access multiplexer). Please
refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information
on PPP.

5.1.1.4 RFC 1483

RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation
Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single
ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each
protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer
to the RFC for more detailed information.

5.1.2 Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be
sure to use the multiplexing method required by your ISP.

5.1.2.1 VC-based Multiplexing

In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit;
for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments
where dynamic creation of large numbers of ATM VCs is fast and economical.

5.1.2.2 LLC-based Multiplexing

In this case one VC carries multiple protocols with protocol identifying information being
contained in each packet header. Despite the extra bandwidth and processing overhead, this
method may be advantageous if it is not practical to have a separate VC for each carried
protocol, for example, if charging heavily depends on the number of simultaneous VCs.

5.1.3 Encapsulation and Multiplexing Scenarios

For Internet access you should use the encapsulation and multiplexing methods used by your
ISP. Consult your telephone company for information on encapsulation and multiplexing
methods for LAN-to-LAN applications, for example between a branch office and corporate
headquarters. There must be prior agreement on encapsulation and multiplexing methods

because they cannot be automatically determined. What method(s) you use also depends on
how many VCs you have and how many different network protocols you need. The extra
overhead that ENET ENCAP encapsulation entails makes it a poor choice in a LAN-to-LAN
application. Here are some examples of more suitable combinations in such an application.

5.1.3.1 Scenario 1: One VC, Multiple Protocols

PPPoA (RFC-2364) encapsulation with VC-based multiplexing is the best combination
because no extra protocol identifying headers are needed. The PPP protocol already contains
this information.

5.1.3.2 Scenario 2: One VC, One Protocol (IP)

Selecting RFC-1483 encapsulation with VC-based multiplexing requires the least amount of
overhead (0 octets). However, if there is a potential need for multiple protocol support in the
future, it may be safer to select PPPoA encapsulation instead of RFC-1483, so you do not
need to reconfigure either computer later.

5.1.3.3 Scenario 3: Multiple VCs

P-660H/HW-D Series User’s Guide

If you have an equal number (or more) of VCs than the number of protocols, then select RFC­1483 encapsulation and VC-based multiplexing.

5.1.4 VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI)
numbers assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to
65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix for
more information.

5.1.5 IP Address Assignment

A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you
a different one each time. The Single User Account feature can be enabled or disabled if you
have either a dynamic or static IP. However the encapsulation method assigned influences
your choices for IP address and ENET ENCAP gateway.

5.1.5.1 IP Assignment with PPPoA or PPPoE Encapsulation

If you have a dynamic IP, then the IP Address and ENET ENCAP Gateway fields are not
applicable (N/A). If you have a static IP, then you only need to fill in the IP Address field and
not the ENET ENCAP Gateway field.

5.1.5.2 IP Assignment with RFC 1483 Encapsulation

In this case the IP Address Assignment must be static with the same requirements for the IP
Address and ENET ENCAP Gateway fields as stated above.
