Preface

There are two Prestige 650HW models, one for ADSL over POTS (Plain Old Telephone System) and one
for ADSL over ISDN (Integrated Synchronous Digital System). Both models are discussed together in this
guide.

The Prestige 650HW ADSL router is the ideal all-in-one device for small networks connecting to the
Internet via ADSL. You don’t need to buy an external hub. The Prestige is equipped with four auto-sensing
10/100BASE-T Ethernet ports to connect to your network and an RJ-11 port (POTS) or RJ-45 port (ISDN)
to connect to your ADSL service.

The Prestige's 10/100M auto-negotiating LAN interface enables fast data transfer of either 10Mbps or
100Mbps in either half-duplex or full-duplex mode depending on your Ethernet network using either a
crossover or straight-through Ethernet cable.

The Prestige comes with a PCMCIA wireless card slot for an optional 802.11b wireless card that provides
wireless LAN connection without the expensive network cabling infrastructure.

The Prestige 650HW is interoperable with all major DSLAM solutions vendors. The Prestige can run
maximum upstream transmission rates of up to 832Kbps and maximum downstream transmission rates of
8Mbps. The actual rate depends on the copper category of your telephone wire, distance from the central
office and the type of ADSL service subscribed to. See the What is DSL section for more background
information on DSL and ADSL

In addition, the Prestige 650HW has bridging and IP routing to support a wide range of applications for
high-speed Internet access.

Your Prestige is easy to install and configure. All functions are configurable via the SMT (System

Preface xvii

Prestige 650HW ADSL Router User’s Guide

What is DSL?

DSL (Digital Subscriber Line) technology enhances the data capacity of the existing twisted-pair wire that
runs between the local telephone company switching offices and most homes and offices. While the wire
itself can handle higher frequencies, the telephone switching equipment is designed to cut off signals above
4,000 Hz to filter noise off the voice line, but now everybody is searching for ways to get more bandwidth to
improve access to the Web - hence DSL technologies.

There are actually seven types of DSL service, ranging in speeds from 16 Kbits/sec to 52 Mbits/sec. The
services are either symmetrical (traffic flows at the same speed in both directions), or asymmetrical (the
downstream capacity is higher than the upstream capacity). Asymmetrical services (ADSL) are suitable for
Internet users because more information is usually downloaded than uploaded. For example, a simple button
click in a web browser can start an extended download that includes graphics and text.

As data rates increase, the carrying distance decreases. That means that users who are beyond a certain
distance from the telephone company’s central office may not be able to obtain the higher speeds.

A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and there is no
dialing required.

What is ADSL?

It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream
data rate. As mentioned, this works well for a typical Internet session in which more information is
downloaded, for example, from Web servers, than is uploaded. ADSL operates in a frequency range that is
above the frequency range of voice services, so the two systems can operate over the same cable.

 Wireless LAN MAC Address Filtering

Getting To Know Your Prestige 1-1

Prestige 650HW ADSL Router User’s Guide

MAC Address Filtering together with ESSID (Extended Service Set IDentifier) and WEP (Wired

Equivalent Privacy) ensure the most secure wireless solution avaliable.

 PPPoE Support (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

Prestige 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.

 NAT for Single-IP-address Internet Access

The Prestige's SUA (Single User Account) feature allows multiple-user Internet access for the cost of a

single IP account. NAT supports popular Internet applications such as MS traceroute, CuSeeMe, IRC,

RealPlayer, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.

 10/100M Auto-negotiation Ethernet/Fast Ethernet Interface

This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust

appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either

half-duplex or full-duplex mode depending on your Ethernet network.

 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 client.

 Multiple PVC (Permanent Virtual Circuits) Support

Your Prestige supports up to 8 PVC’s.

 ADSL Transmission Rate Standards

♦ Full-Rate (ANSI T1.413, Issue 2; G.dmt (G.992.1) with line rate support of up to 8 Mbps

downstream and 832 Kbps upstream.

the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige 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 Prestige 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 Prestige supports three logical LAN interfaces via its single physical Ethernet

interface with the Prestige itself as the gateway for each LAN network.

♦ IP Policy Routing (IPPR)

2.4 P650HW with POTS

Sections 2.4.1 and 2.4.2 relate to people who use the Prestige with ADSL over POTS (analog telephone
service) only.

2-4 Hardware Installation and Initial Setup

Prestige 650HW ADSL Router User’s Guide

2.4.1 Connecting a POTS Splitter

This is for the Prestige that follows the Full Rate (G.dmt) standard only. One major difference between
ADSL and dial-up modems is the optional telephone splitter. This device keeps the telephone and ADSL
signals separated, giving them the capability to provide simultaneous Internet access and telephone service
on the same line. Splitters also eliminate the destructive interference conditions caused by telephone sets.
The purchase of a POTS splitter is optional.

Noise generated from a telephone in the same frequency range, as the ADSL signal can be disruptive to the
ADSL signal. In addition the impedance of a telephone when off-hook may be so low that it shunts the
strength of the ADSL signal. When a POTS splitter is installed at the entry point, where the line comes into
the home, it will filter the telephone signals before combining the ADSL and telephone signals transmitted
and received. The issues of noise and impedance are eliminated with a single POTS splitter installation.

A telephone splitter is easy to install as shown in the following figure.

Figure 2-3 Connecting a POTS Splitter

Step 1. Connect the side labeled “Phone” to your telephone.

Step 2. Connect the side labeled “Modem” to your Prestige.

Step 3. Connect the side labeled “Line” to the telephone wall jack.

2.4.2 Telephone Microfilters

Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL
transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter,
for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice
transmissions. The purchase of a telephone microfilter is optional.

Step 1. Connect a phone cable from the wall jack to the single jack end of the Y- Connector.

Hardware Installation and Initial Setup 2-5

Prestige 650HW ADSL Router User’s Guide

Step 2. Connect a cable from the double jack end of the Y-Connector to the “wall side” of the

At this point, you should have connected the ADSL line, the Ethernet port and the power port to the
appropriate devices or lines. Push in the power button (located on the back of your Prestige) to turn on your
Prestige.

2.7 Configuring Your Prestige For Internet Access

Configure your Prestige for Internet access using:

 Web configurator (refer to the Read Me First).

 SMT (System Management Terminal). Access the SMT via LAN or WAN using Telnet.

2.7.1 Connect to your Prestige Using Telnet

The following procedure details how to telnet into your Prestige.

Step 1. In Windows, click Start (usually in the bottom left corner), Run and then type “telnet

192.168.1.1” (the default IP address) and click OK.

Step 2. Enter “1234” in the Password field.

Step 3. After entering the password you will see the main menu.

Please note that if there is no activity for longer than five minutes (default timeout period) after you log in,
your Prestige will automatically log you out. You will then have to telnet into the Prestige again.

2.7.2 Connect to your Prestige Using the Web Configurator

Step 1. Launch your web browser.
Step 2. Enter “192.168.1.1” as the URL.
Step 3. In the User Name field, type "admin". In the Password field, type “1234”. Click OK.

Click the Help button for online web configurator HTML help.

The remainder of this user’s guide shows you how to configure the Prestige for Internet access using SMT
screens. There are also some sections in this guide that also focus on using Telnet to configure the Prestige.

2.7.3 Entering Password

The login screen appears after you press [ENTER], prompting you to enter the password, as shown next.

For your first login, enter the default password “1234”. As you type the password, the screen displays an
“*” for each character you type.

2.8 Resetting the Prestige

If you forget your password or cannot access the Prestige, you will need to reload the factory-default
configuration file. 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; the
password will be reset to “1234” and the LAN IP address to 192.168.1.1.

To obtain the default configuration file, download it from the ZyXEL FTP site, unzip it and save it in a
folder.

2.8.1 Methods of Restoring Factory-Defaults

You can erase the current configuration and restore factory defaults in three ways:

1. Transfer the configuration file to your Prestige using the SMT menus. See later in this User’s Guide for
more information on this.

2. Use the Restore Factory Defaults/Reboot button on the rear panel of the Prestige to upload the
default configuration file (hold this button in for more than 3 seconds). Use this method for cases when
the password or IP address of the Prestige is not known.

3. Use the web configurator to restore defaults (see the web configurator HTML help)

tab, note the entry for the Computer name field and enter it as the Prestige System Name.

• In Windows 2000 click Start->Settings->Control Panel and then double-click System. Click the
Network Identification tab and then the Properties button. Note the entry for the Computer
name field and enter it as the Prestige System Name.

• In Windows XP, click start -> My Computer -> View system information and then click the
Computer Name tab. Note the entry in the Full computer name field and enter it as the Prestige
System Name.

2-12 Hardware Installation and Initial Setup

Prestige 650HW ADSL Router User’s Guide

The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this blank,
the domain name obtained by DHCP from the ISP is used. While you must enter the host name (System
Name) on each individual computer, the domain name can be assigned from the Prestige via DHCP.

2.11.1 Dynamic DNS

Dynamic DNS (Domain Name System) allows you to update your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe or other services).
You can also access your FTP server or Web site on your own computer using a DNS-like address (for
example, myhost.dhs.org, where myhost is a name of your choice) which will never change instead of using
an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you
even if they don't know your IP address.

First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people
with a dynamic IP from their ISP or DHCP server that would still like to have a DNS name.

To use this service, you must register with the Dynamic DNS service provider. The Dynamic DNS service
provider will give you a password or key. The Prestige supports www.dyndns.org. You can apply to this
service provider for Dynamic DNS service.

DYNDNS Wildcard

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP
address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example,
www.yourhost.dyndns.org and still reach your hostname.

Prestige 650HW ADSL Router User’s Guide

Chapter 3

Internet Access

This chapter shows you how to configure the LAN and WAN of your Prestige for Internet access.

3.1 Factory Ethernet Defaults

The Ethernet parameters of the Prestige are preset in the factory with the following values:

1. IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).

2. DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.

These parameters should work for the majority of installations. If the parameters are satisfactory, you can
skip to TCP/IP Ethernet Setup and DHCP to enter the DNS server address(es) if your ISP gives you explicit
DNS server address(es). If you wish to change the factory defaults or to learn more about TCP/IP, please
read on.

3.2 LANs and WANs

A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same
building or floor of a building. A WAN (Wide Area Network), on the other hand, is an outside connection
to another network or the Internet.

3.2.1 LANs, WANs and the Prestige

The actual physical connection determines whether the Prestige ports are LAN or WAN ports. There are
two separate IP networks, one inside, the LAN network; the other outside: the WAN network as shown
next:

Internet Access 3-1

Prestige 650HW ADSL Router User’s Guide

Figure 3-1 LAN & WAN IPs

3.3 TCP/IP Parameters

3.3.1 IP Address and Subnet Mask

Like houses on a street that share a common street name, the 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. If this is the case, it is
recommended that you select a network number from 192.168.0.0 to 192.168.255.0 (ignoring the trailing
zero) and you must enable the Single User Account feature of the Prestige. 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.

The subnet mask specifies the network number portion of an IP address. Your Prestige 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 Prestige unless you are instructed to do otherwise.

3-2 Internet Access

Prestige 650HW ADSL Router User’s Guide

3.3.2 Private IP Addresses

Every machine on the Internet must have a unique address. If your networks are isolated from the Internet,
for example, 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:

10.0.0.0 — 10.255.255.255

172.16.0.0 — 172.31.255.255

192.168.0.0 — 192.168.255.255

You can obtain your IP address from the IANA, from an ISP or it can be assigned from 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.

3.3.3 RIP Setup

RIP (Routing Information Protocol) allows a router to exchange routing information with other routers.
The RIP Direction field controls the sending and receiving of RIP packets. When set to:

1. Both - the Prestige will broadcast its routing table periodically and incorporate the RIP information
that it receives.

2. In Only - the Prestige will not send any RIP packets but will accept all RIP packets received.

3. Out Only - the Prestige will send out RIP packets but will not accept any RIP packets received.

4. None - the Prestige will not send any RIP packets and will ignore any RIP packets received.

The Version field controls the format and the broadcasting method of the RIP packets that the Prestige
sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more
information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology.

Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses
subnet broadcasting while RIP-2M uses multicasting.

Internet Access 3-3

Prestige 650HW ADSL Router User’s Guide

3.3.4 DHCP Configuration

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 Prestige has built-in DHCP server
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS
servers to Windows 95, Windows NT and other systems that support the DHCP client. The Prestige can
also act as a surrogate DHCP server where it relays IP address assignment from the actual DHCP server to
the clients.

IP Pool Setup

The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64 for
the client machines. This leaves 31 IP addresses, 192.168.1.2 to 192.168.1.32 (excluding the Prestige itself
which has a default IP of 192.168.1.1) for other server machines, for example, server for mail, FTP, telnet,
web, etc., that you may have.

DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa,
for example, 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 machine before you can access it. The DNS server
addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP
address and subnet mask.

There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a
customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up. If
your ISP does give you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup,
otherwise, leave them blank.

Some ISP’s choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control
Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the
DNS servers are conveyed through IPCP negotiation. The Prestige supports the IPCP DNS server
extensions through the DNS proxy feature.

If the Primary and Secondary DNS Server fields in DHCP Setup are not specified, for instance, left as

0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS
query to the Prestige, the Prestige forwards the query to the real DNS server learned through IPCP and
relays the response back to the computer.

Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not
mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you
explicit DNS servers, make sure that you enter their IP addresses in the DHCP Setup menu. This way, the
Prestige can pass the DNS servers to the computers and the computers can query the DNS server directly
without the Prestige’s intervention.

3-4 Internet Access

Prestige 650HW ADSL Router User’s Guide

3.4 IP 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 is a third way to deliver IP packets to a group
of hosts on the network - not everybody.

IGMP (Internet Group Multicast Protocol) is a session-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 Prestige supports both IGMP version 1 (IGMP-v1) and version 2 (IGMP-v2). At start up, the Prestige
queries all directly connected networks to gather group membership. After that, the Prestige periodically
updates this information. IP Multicasting can be enabled/disabled on the Prestige LAN and/or WAN
interfaces using menus 3.2 (LAN) and 11.3 (WAN). Select None to disable IP Multicasting on these
interfaces.

3.5 IP Policies

Traditionally, routing is based on the destination address only and the router takes the shortest path to
forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior
and alter the packet forwarding based on the policy defined by the network administrator. Policy-based
routing is applied to incoming packets on a per interface basis, prior to the normal routing. Create policies
using SMT menu 25 (see IP Policy Routing) and apply them on the Prestige LAN and/or WAN interfaces
using menus 3.2 (LAN) and 11.3 (WAN).

3.6 IP Alias

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

3.9 Wireless LAN

Your Prestige comes with a PCMCIA wireless card slot for 802.11b wireless LAN connectivity. With the
wireless LAN feature you can configure your Prestige that allows wireless clients to communicate with any
computer on your wired Ethernet network or to connect to the Internet via ADSL.

3.9.1 Wireless LAN Parameters

Channel

You can choose the radio channels depending on your geographical area.

ESS ID

Wireless LANs can be as simple as two computers with wireless network interface cards (NICs)
communicating in a peer-to-peer network or as complex as a number of computers with wireless NICs
communicating through access points (APs), which bridge network traffic to the wired LAN. You can setup
the Prestige as an AP in a peer-to-peer network.

Extended Service Set (ESS) is defined as one or more APs that connect to a specific wired Ethernet LAN
and their associated wireless clients. The ESS ID is a unique ID given to the access point and the wireless
clients that participate in the same wireless network. You can think the EES ID as being similar to a
workgroup name in a Microsoft network.

RTS Threshold

The RTS Threshold prevents the hidden node problem. Hidden node problem occurs when two stations are
within the range of the same access point, but are not within the range of each other. The following figure
illustrates the hidden node problem. Both stations (STA) are within the range of the AP, however, they
cannot hear each other. Therefore, they are considered as hidden nodes from each other. When a station
starts data transmission with the access point, it might not know that the other station is already using the
wireless medium. When these two stations send data at the same time, they might collide when arriving
simultaneously at the AP. The collision will most certainly results in a loss of messages for both stations.

Internet Access 3-11

Prestige 650HW ADSL Router User’s Guide

Figure 3-8 RTS Threshold

Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS
Threshold on a possible hidden station, this station and its AP will use a Request to Send/Clear to Send
protocol (RTS/CTS). The station will send an RTS message to the AP, informing that it is going to transmit
the data. Upon receipt, the Access Point will respond with a CTS message to all stations within its range to
notify all other stations to defer transmission. It will also confirm with the requesting station that the AP has
reserved it for the time frame of the requested transmission.

The RTS function will be activated if the packet size exceeds the value you set. It is highly recommended
that you set the value ranging from 0 to 2432.

Enabling the RTS Threshold causes redundant network overhead that could

negatively affect the throughput performance instead of providing a remedy.

Fragmentation Threshold

Fragmentation improves the efficiency when high traffic flows along in the wireless network.

WEP

The 11 Mbps wireless LAN provides powerful features such as WEP security. ZyXEL recommends that
you change the ESSID setting of all devices on your network to a unique value, not the default value. A

3-12 Internet Access

Prestige 650HW ADSL Router User’s Guide

further improvement in security can be obtained by using Wired Equivalent Privacy (WEP) data encryption.
However, there may be a significant degradation of the data throughput on the wireless link when WEP is
enabled.

Prestige 650HW ADSL Router User’s Guide

3.10 Internet Access Setup

3.11 VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers
supplied by your telephone company. 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 Appendices for more
information.

3.12 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.

3.12.1 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.

3.12.2 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.

3.13 Encapsulation

Be sure to use the encapsulation method required by your ISP. The Prestige supports the following
methods.

3.13.1 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 Ethernet
Encapsulation Gateway field in menu 4 and in the Rem IP Addr field in menu 11.1. You can get this
information from your ISP.

3-16 Internet Access

Prestige 650HW ADSL Router User’s Guide

3.13.2 PPP over Ethernet

PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP.
The Prestige bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an
ATM PVC (Permanent Virtual Circuit) which connects to an xDSL Access Concentrator where the PPP
session terminates. One PVC can support any number of PPP sessions from your LAN. For more
information on PPPoE, see the Appendices.

3.13.3 PPPoA

Please refer to RFC 2364 for more information on PPP over ATM Adaptation Layer 5 (AAL5). Refer to
RFC 1661 for more information on PPP.

3.13.4 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.

3.14 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.

3.14.1 Using 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.

3.14.2 Using 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.

3.14.3 Using ENET ENCAP Encapsulation

In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP Address and
ENET ENCAP Gateway fields as supplied by your ISP. However for a dynamic IP, the Prestige acts as a

Internet Access 3-17

Prestige 650HW ADSL Router User’s Guide

(N/A) as they are assigned to the Prestige by the DHCP server.

3.15 Internet Access Configuration

Menu 4 allows you to enter the Internet Access information in one screen. Menu 4 is actually a simplified
setup for one of the remote nodes that you can access in menu 11. Before you configure your Prestige for
Internet access, you need to collect your Internet account information from your ISP and telephone

3.15.1 Traffic Shaping

Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate and
“burstiness” or fluctuation of data transmission over an ATM network. This agreement helps eliminate
congestion, which is important for transmission of real time data such as audio and video connections.

Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower
(but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of
832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on
the line speed.

Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be sent at the peak
rate, and a parameter for burst-type traffic. SCR may not be greater than the PCR; the system default is 0
cells/sec.

Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is
reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to
the MBS) can be sent at the PCR again.

If the PCR, SCR or MBS is set to the default of “0”, the system will assign a

maximum value that correlates to your upstream line rate.

The following figure illustrates the relationship between PCR, SCR and MBS.

Remote Node Configuration

This chapter covers the parameters that are protocol-independent. Protocol-dependent

configuration (TCP/IP and Bridging) is covered in the following chapters.

A remote node is required for placing calls to a remote gateway. A remote node represents both the remote

gateway and the network behind it across a WAN connection. When you use menu 4 to set up Internet

access, you are configuring one of the remote nodes.

4.1 Remote Node Setup

This section describes the protocol-independent parameters for a remote node.

To configure a remote node, follow these steps:

Step 1. From the main menu, enter 11 to display Menu 11 - Remote Node Setup.

Step 2. When menu 11 appears, as shown in the following figure, type the number of the remote node

4.1.2 Encapsulation and Multiplexing Scenarios

For Internet access you should use the encapsulation and multiplexing methods used by your ISP. For

LAN-to-LAN applications, for example, between a branch office and corporate headquarters, prior

agreement on methods is necessary because encapsulation and multiplexing cannot be automatically

determined. What method(s) you use 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.

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.

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.

Scenario 3. Multiple VCs

If you have an equal number (or more) of VCs than the number of protocols, then select RFC-1483

encapsulation and VC-based multiplexing.

4-2 Remote Node Configuration

Nailed-Up Connection (PPP)

A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand.

The Prestige does two things when you specify a nailed-up connection. The first is that idle timeout is

disabled. The second is that the Prestige will try to bring up the connection when turned on and whenever

the connection is down. A nailed-up connection can be very expensive for obvious reasons.

Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a

constant connection and the cost is of no concern

For obvious reasons, you should employ the strongest authentication protocol possible. However, some

vendors’ implementation includes specific authentication protocol in the user profile. It will disconnect if

the negotiated protocol is different from that in the user profile, even when the negotiated protocol is

stronger than specified. If the peer disconnects right after a successful authentication, make sure that you

specify the correct authentication protocol when connecting to such an implementation.

5.1.2 IP Static Route Setup

Static routes tell the Prestige routing information that it cannot learn automatically through other means.

This can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is

directly connected to a remote node.

Remote Node TCP/IP Configuration 5-5

Prestige 650HW ADSL Router User’s Guide

Each remote node specifies only the network to which the gateway is directly connected and the Prestige

has no knowledge of the networks beyond. For instance, the Prestige knows about network N2 in the

following figure through remote node Router 1. However, the Prestige is unable to route a packet to

network N3 because it does not know that there is a route through remote node Router 1 (via Router 2). The

static routes allow you to tell the Prestige about the networks beyond the remote nodes.

Prestige 650HW ADSL Router User’s Guide

Table 5-3 Edit IP Static Route Menu Fields

FIELD DESCRIPTION

Destination IP Address This parameter specifies the IP network address of the final destination.

Routing is always based on network number. If you need to specify a route to
a single host, use a subnet mask of 255.255.255.255 in the subnet mask field
to force the network number to be identical to the host ID.

IP Subnet Mask Type the subnet mask for this destination. Follow the discussion on IP Subnet

Mask in this manual.

Gateway IP Address Type the IP address of the gateway. The gateway is an immediate neighbor of

your Prestige that will forward the packet to the destination. On the LAN, the
gateway must be a router on the same segment as your Prestige; over WAN,
the gateway must be the IP address of one of the remote nodes.

Metric Metric represents the “cost” of transmission for routing purposes. IP routing

uses hop count as the measurement of cost, with a minimum of 1 for directly
connected networks. Type a number that approximates the cost for this link.
The number need not be precise, but it must be between 1 and 15. In practice,
2 or 3 is usually a good number.

Private This parameter determines if the Prestige will include the route to this remote

node in its RIP broadcasts. If set to Yes, this route is kept private and is not
included in RIP broadcasts. If No, the route to this remote node will be
propagated to other hosts through RIP broadcasts.

Chapter 6

Bridging Setup

This chapter shows you how to configure the bridging parameters of your Prestige.

6.1 Bridging in General

Bridging bases the forwarding decision on the MAC (Media Access Control), or hardware address, while

routing does it on the network layer (IP) address. Bridging allows the Prestige to transport packets of

network layer protocols that it does not route, for example, SNA, from one network to another. The caveat

is that, compared to routing, bridging generates more traffic for the same network layer protocol, and it also

demands more CPU cycles and memory.

For efficiency reasons, do not turn on bridging unless you need to support protocols other than IP on your

network. For IP, enable the routing if you need it; do not bridge what the Prestige can route.

6.2 Bridge Ethernet Setup

Basically, all non-local packets are bridged to the WAN. Your Prestige does not support IPX.

6.2.1 Remote Node Bridging Setup

Follow the procedure in another section to configure the protocol-independent parameters in Menu 11.1 –

Remote Node Profile. For bridging-related parameters, you need to configure Menu 11.3 – Remote Node

Network Layer Options.

To setup Menu 11.3 – Remote Node Network Layer Options shown in the next figure, follow these steps:

Step 1. In menu 11.1, make sure the Bridge field is set to Yes.

Step 2. Move the cursor to the Edit IP/Bridge field, then press [SPACE BAR] to set the value to Yes

Chapter 7

Network Address Translation (NAT)

This chapter discusses how to configure NAT on the Prestige.

7.1 Introduction

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a

packet, for example, the source address of an outgoing packet, used within one network to a different IP

address known within another network.

7.1.1 NAT Definitions

Inside/outside denotes where a host is located relative to the Prestige, for example, the computers of your

subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.

Global/local denotes the IP address of a host in a packet as the packet traverses a router, for example, the

local address refers to the IP address of a host when the packet is in the local network, while the global

address refers to the IP address of the host when the same packet is traveling in the WAN side.

Note that inside/outside refers to the location of a host, while global/local refers to the IP address of a host

used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in a packet when

the packet is still in the local network, while an inside global address (IGA) is the IP address of the same

inside host when the packet is on the WAN side. The following table summarizes this information.

Table 7-1 NAT Definitions

ITEM DESCRIPTION

Inside This refers to the host on the LAN.

Outside This refers to the host on the WAN.

Local This refers to the packet address (source or destination) as the packet travels on the LAN.

Global This refers to the packet address (source or destination) as the packet travels on the WAN.

NAT 7-1

Prestige 650HW ADSL Router User’s Guide

NAT never changes the IP address (either local or global) of an outside host.

7.1.2 What NAT Does

In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside

local address) to another (the inside global address) before forwarding the packet to the WAN side. When

the response comes back, NAT translates the destination address (the inside global address) back to the

inside local address before forwarding it to the original inside host. Note that the IP address (either local or

global) of an outside host is never changed.

The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In

addition, you can designate servers, for example, a web server and a telnet server, on your local network

and make them accessible to the outside world. Although you can make designated servers on the LAN

accessible to the outside world, it is strongly recommended that you attach those servers to the DMZ port

instead. If you do not define any servers (for Many-to-One and Many-to-Many Overload mapping – see

Table 7-2), NAT offers the additional benefit of firewall protection. With no servers defined, your Prestige

filters out all incoming inquiries, thus preventing intruders from probing your network. For more

information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).

7.1.3 How NAT Works

Each packet has two addresses – a source address and a destination address. For outgoing packets, the ILA

(Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source

address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is

the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones

required for communication with hosts on other networks. It replaces the original IP source address (and

TCP or UDP source port numbers for Many-to-One and Many-to-Many Overload NAT mapping) in each

packet and then forwards it to the Internet. The Prestige keeps track of the original addresses and port

numbers so incoming reply packets can have their original values restored. The following figure illustrates

this.

7.1.4 NAT Application

The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using

IP Alias) behind the Prestige can communicate with three distinct WAN networks. More examples follow at

the end of this chapter.

7.1.5 NAT Mapping Types

NAT supports five types of IP/port mapping. They are:

1. One to One: In One-to-One mode, the Prestige maps one local IP address to one global IP address.

2. Many to One: In Many-to-One mode, the Prestige maps multiple local IP addresses to one global IP

address. This is equivalent to SUA (for instance, PAT, port address translation), ZyXEL’s Single User

Account feature that previous ZyXEL routers supported (the SUA Only option in today’s routers).

3. Many to Many Overload: In Many-to-Many Overload mode, the Prestige maps the multiple local IP

addresses to shared global IP addresses.

7-4 NAT

Prestige 650HW ADSL Router User’s Guide

4. Many-to-Many No Overload: In Many-to-Many No Overload mode, the Prestige maps each local IP

address to a unique global IP address.

5. Server: This type allows you to specify inside servers of different services behind the NAT to be

accessible to the outside world although, it is highly recommended that you use the DMZ port for these

servers instead.

Port numbers do not change for One-to-One and Many-to-Many No Overload NAT

mapping types.

The following table summarizes these types.

7.2 Using NAT

7.2.1 SUA (Single User Account) Versus NAT

SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two types of

mapping, Many-to-One and Server. See section 7.3.1 for a detailed description of the NAT set for SUA.

The Prestige also supports Full Feature NAT to map multiple global IP addresses to multiple private LAN

IP addresses of clients or servers using mapping types as outlined in Table 7-2.

1. Choose SUA Only if you have just one public WAN IP address for your Prestige.

2. Choose Full Feature if you have multiple public WAN IP addresses for your Prestige.

7.2.2 Applying NAT

You apply NAT via menus 4 or 11.3 as displayed next. The next figure shows you how to apply NAT for

Internet access in menu 4. Enter 4 from the main menu to go to Menu 4 - Internet Access Setup.

7.3 NAT Setup

Use the Address Mapping Sets menus and submenus to create the mapping table used to assign global

addresses to computers on the LAN. You can see two NAT Address Mapping sets in menu 15.1. You can

only configure Set 1. Set 255 is used for SUA. When you select Full Feature in menu 4 or 11.3, the

SMT will use Set 1, which supports all mapping types as outlined in Table 7-2. When you select SUA

Only, the SMT will use the pre-configured Set 255 (read only).

The Server Set is a list of LAN side servers mapped to external ports. To use this set (one set for the

Prestige 10), a server rule must be set up inside the NAT Address Mapping set. Please see section 7.4 for

further information on these menus. To configure NAT, enter 15 from the main menu to bring up the

following screen.
