Prestige 645R-A Series User’s Guide

Introduction to 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.

Prestige 645R-A Series User’s Guide

Chapter 1

Getting To Know Your Prestige

This chapter describes the key features and applications of your Prestige.

1.1 Introducing the Prestige 645R-A Series

Your Prestige integrates a high-speed 10/100Mbps auto-negotiating LAN interface and a high-speed DSL
port into a single package. The Prestige is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks.

The web browser-based Graphical User Interface provides easy management and is totally independent of the
operating system platform you use.

1.2 Features of the Prestige

Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.

Ease of Installation

Your Prestige is designed for quick, intuitive and easy installation. Physically, its compact size and lightness
make it easy to position anywhere in your busy office.

High Speed Internet Access

The Prestige supports downstream transmission rates of up to 8Mbps and upstream transmission rates of 800
Kbps.

10/100Mbps Auto-negotiating Fast Ethernet LAN 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.

Protocols Supported

• TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.

• PPP (Point-to-Point Protocol) link layer protocol.

Getting To Know Your Prestige 1-1

Prestige 645R-A Series User’s Guide

• Transparent bridging for unsupported network layer protocols.

• DHCP Client, Server and Relay

• RIP I and RIP II

IP Policy Routing

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.

Call Scheduling

Configure call time periods to allow and restrict access to remote nodes.

Networking Compatibility

Your Prestige is compatible with the major ADSL DSLAM (Digital Subscriber Line Access Multiplexer)
providers, making configuration as simple as possible for you.

Multiplexing

Your Prestige supports VC-based and LLC-based multiplexing.

Encapsulation

The Prestige supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation
over ATM and MAC encapsulated routing (ENET ENCAP) as well as PPP over Ethernet (RFC 2516).

SNMP

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information
between network devices. SNMP is a member of the TCP/IP protocol suite. Your Prestige supports SNMP
agent functionality, which allows a manager station to manage and monitor the Prestige through the network.
The Prestige supports SNMP version one (SNMPv1) and version two (SNMPv2).

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).

Full Network Management

• SNMP (Simple Network Management Protocol) support.

• SMT (System Management Terminal) through a telnet connection.

• Web configurator.

1-2 Getting To Know Your Prestige

Prestige 645R-A Series User’s Guide

PAP and CHAP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure since the password is scrambled prior to transmission.
However, PAP is readily available on more platforms.

Filters

The Prestige's packet filtering functions allow added network security and management.

Reset Button

The Prestige comes with a reset button built into the rear panel. Use this button to restore the factory default
password to 1234, IP address to 192.168.1.1, subnet mask to 255.255.255.0 and DHCP server enabled with a
pool of 32 IP addressed starting at 192.168.1.33.

1.3 Applications for the Prestige

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

1.3.1 Internet Access

The Prestige is the ideal high-speed Internet access solution. Your Prestige supports the TCP/IP protocol,
which the Internet uses exclusively. It is compatible with all major ADSL DSLAM providers. A DSLAM is
a rack of ADSL line cards with data multiplexed into a backbone network interface/connection (e.g., T1,
OC3, DS3, ATM or Frame Relay). Think of it as the equivalent of a modem rack for ADSL. A typical
Internet Access application is shown next.

The following figures show the rear panel of your Prestige.

Figure 2-2 Rear Panel

2.2.1 DSL Port

Connect the Prestige directly to the wall jack using the included DSL cable. Connect a microfilter(s) between
the wall jack and your telephone(s). A microfilter acts as low-pass filter (voice transmission takes place in
the 0 to 4KHz bandwidth) and is an optional purchase.

2-2 Hardware Installation

Prestige 645R-A Series User’s Guide

2.2.2 One Auto-crossover LAN 10/100M Port

Ethernet 10Base-T/100Base-T networks use Shielded Twisted Pair (STP) cable with RJ-45 that look like a
bigger telephone plug with 8 pins. The LAN port is auto-crossover, so you may use a crossover or a straight­through Ethernet cable to connect your Prestige to a computer or an external hub.

When the Prestige is on and properly connected to a computer or a hub, the LAN

LED on the front panel turns on.

2.2.3 Using the Reset Button

Hold this button in for more than five seconds to restart the Prestige.

Resetting the Prestige deletes all custom configurations.

2.2.4 Making the Connections

Step 1. Connecting the DSL line

Connect the RJ-11 DSL port on the Prestige to the POTS splitter using the included DSL cable (telephone
wire). Connect the micro filter(s) (optional– see the Splitters and Microfilters appendix for the details)
between the wall jack and your telephone(s). The micro filters act as low pass filters (voice transmission
takes place in the 0 to 4KHz bandwidth).

Step 2. Connecting a computer or an external hub to the Prestige’s 10/100M LAN port

Be careful not to insert an RJ-11 connector into the RJ-45 port.

Ethernet 10Base-T/100Base-T networks use Shielded Twisted Pair (STP) cable with RJ-45 connectors that
look like a bigger telephone plug with 8 pins. The LAN port is auto-crossover, so you may use a crossover or
a straight-through Ethernet cable to connect your Prestige to a computer or an external hub.

Step 3. Connecting the power adaptor to your Prestige

Make sure that you use the supplied power adaptor. See Power Adaptor

Specifications appendix for information.

Connect the power adaptor to the port labeled POWER on the rear panel of your Prestige.

2.3 Additional Installation Requirements

3.5 Resetting the Prestige

If you forget your password or cannot access the Prestige, you will need to reload the factory-default
configuration file or use the RESET button the back of the Prestige. Uploading this configuration file
replaces the current configuration file with the factory-default configuration file. This means that you will
lose all configurations that you had previously. The password will be reset to “1234”, also.

3.5.1 Using The Reset Button

Make sure the PWR LED is on (not blinking) when you begin this procedure.

1. Press the RESET button for more than five seconds, then release it. If the PWR LED begins to blink,
the defaults have been restored and the Prestige restarts. Otherwise, go to step 2.

2. Turn the Prestige off.

3. While pressing the RESET button, turn the Prestige on.

Continue to hold the RESET button. The PWR LED will begin to blink and flicker very quickly after about
10 or 15 seconds. This indicates that the defaults have been restored and the Prestige is now restarting.

Wizard Setup

This chapter provides information on the Wizard Setup screens in the web configurator.

4.1 Wizard Setup Introduction

Use the Wizard Setup screens to configure your system for Internet access settings and fill in the fields with
the information in the Internet Access Checklist table of the Read Me First. Your ISP may have already
configured some of the fields in the wizard screens for you.

4.2 Encapsulation

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

4.2.1 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 the second wizard screen. You can get this information from your ISP.

4.2.2 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 ADSL 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 appendix.

4.2.3 PPPoA

PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). It provides access control
and billing functionality in a manner similar to dial-up services using PPP. The Prestige 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.

Wizard Setup 4-1

Prestige 645R-A Series User’s Guide

4.2.4 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.

4.3 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.

4.3.1 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.

4.3.2 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.

4.4 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.

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. If this is the case, it is
recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the

4-4 Wizard Setup

Prestige 645R-A Series User’s Guide

Network Address Translation (NAT) 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.

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 Prestige, 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 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.

4.7 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.

4.7.1 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.

4.7.2 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.

4.7.3 IP Assignment with 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
DHCP client on the WAN port and so the IP Address and ENET ENCAP Gateway fields are not applicable
(N/A) as the DHCP server assigns them to the Prestige.

Wizard Setup 4-5

Prestige 645R-A Series User’s Guide

4.7.4 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.

4.8 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

4.9 NAT

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.

LAN Setup

This chapter describes how to configure LAN settings.

5.1 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 and manage IP addresses.

5.1.1 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:

Figure 5-1 LAN and WAN IP Addresses

5.2 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.

LAN Setup 5-1

Prestige 645R-A Series User’s Guide

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 gives 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.

5.3 DNS Server Address Assignment

Use DNS (Domain Name System) to map 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.

There are two ways that an ISP disseminates the DNS server addresses.

1. The 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 DHCP Setup.

2. Leave the DNS Server fields in DHCP Setup blank (for example 0.0.0.0). The Prestige acts as a DNS
proxy when this field is blank.

5.4 LAN TCP/IP

The Prestige has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that
support DHCP client capability.

5.4.1 Factory LAN Defaults

The LAN parameters of the Prestige 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.

5-2 LAN Setup

Prestige 645R-A Series User’s Guide

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.

5.4.2 IP Address and Subnet Mask

Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter for this information.

5.4.3 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.

5.4.4 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 Prestige supports both IGMP version 1 (IGMP-v1) and IGMP 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 in the web configurator (LAN; WAN). Select None to disable IP multicasting on these
interfaces.

Network Address Translation (NAT)

This chapter discusses how to configure NAT on the Prestige.

6.1 NAT Overview

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.

6.1.1 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 6-1 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 never changes the IP address (either local or global) of an outside host.

6.1.2 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

NAT 6-1

Prestige 645R-A Series User’s Guide

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. 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).

6.1.3 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.

Figure 6-1 How NAT Works

6-2 NAT

Prestige 645R-A Series User’s Guide

6.1.4 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.

Figure 6-2 NAT Application With IP Alias

6.1.5 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.

NAT 6-3

Prestige 645R-A Series 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.

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

mapping types.

The following table summarizes these types.

6.2 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. 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 6-2.

6-4 NAT

Prestige 645R-A Series User’s Guide

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.

6.3 SUA Server

A SUA server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can
make visible to the outside world even though SUA makes your whole inside network appear as a single
computer to the outside world.

You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of
the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on
port 21. In some cases, such as for unknown services or where one server can support more than one service
(for example both FTP and web service), it might be better to specify a range of port numbers. You can
allocate a server IP address that corresponds to a port or a range of ports.

Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or
FTP server) from your location. Your ISP may periodically check for servers and may suspend your account
if it discovers any active services at your location. If you are unsure, refer to your ISP.

Default Server IP Address

In addition to the servers for specified services, NAT supports a default server IP address. A default server
receives packets from ports that are not specified in this screen.

If you do not assign a Default Server IP Address, then all packets received for ports

not specified in this screen will be discarded.

6.3.1 Port Forwarding: Services and Port Numbers

A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can
make accessible to the outside world even though NAT makes your whole inside network appear as a single
machine to the outside world.

Use the SUA Server page to forward incoming service requests to the server(s) on your local network. You
may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the
desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port

21. In some cases, such as for unknown services or where one server can support more than one service (for
example both FTP and web service), it might be better to specify a range of port numbers.

In addition to the servers for specified services, NAT supports a default server. A service request that does
not have a server explicitly designated for it is forwarded to the default server. If the default is not defined,
the service request is simply discarded.

NAT 6-5

Prestige 645R-A Series User’s Guide

Many residential broadband ISP accounts do not allow you to run any server

processes (such as a Web or FTP server) from your location. Your ISP may

periodically check for servers and may suspend your account if it discovers any

6.6 Configuring Address Mapping

Ordering your rules is important because the Prestige applies the rules in the order that you specify. When a
rule matches the current packet, the Prestige takes the corresponding action and the remaining rules are
ignored. If there are any empty rules before your new configured rule, your configured rule will be pushed up
by that number of empty rules. For example, if you have already configured rules 1 to 6 in your current set
and now you configure rule number 9. In the set summary screen, the new rule will be rule 7, not 9. Now if
you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so old rules 5, 6 and 7 become new rules 4, 5 and

Dynamic DNS Setup

This chapter discusses how to configure your Prestige to use Dynamic DNS.

7.1 Dynamic DNS

Dynamic DNS 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, etc.). You can also access your FTP
server or Web site on your own computer using a DNS-like address (for instance myhost.dhs.org, where
myhost is a name of your choice) that 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. The Dynamic
DNS service provider will give you a password or key.

7.1.1 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.

If you have a private WAN IP address, then you cannot use Dynamic DNS.

General Setup

Menu 1 - General Setup contains administrative and system-related information.

10.1 General Setup

Menu 1 — General Setup contains administrative and system-related information (shown next). The
System Name field is for identification purposes. However, because some ISPs check this name you should

enter your computer's "Computer Name".

• In Windows 95/98 click Start, Settings, Control Panel, Network. Click the Identification 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.

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.
