Prestige 2602R Series User’s Guide

Introduction to DSL

DSL (Digital Subscriber Line) technology enhances the data capacity of the existing twisted­pair 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.

Introduction to 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.

CHAPTER 1

Getting To Know Your Prestige

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

1.1 Introducing the Prestige

The Prestige P2602R ADSL VoIP IAD (Integrated Access Device) combines high-speed
ADSL Internet access and Voice over IP (VoIP) communication capabilities. They allow you
to use a traditional analog telephone to make Internet calls. By integrating DSL and NAT, the
Prestige provides ease of installation and Internet access. The Prestige is also a complete
security solution with a robust firewall and content filtering.

Models ending in “1”, for example P2602R-61, 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 Prestige’s specific model. Refer to the label on the

bottom of your Prestige.

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

Prestige 2602R Series User’s Guide

1.1.1 Features of the Prestige

The following sections describe the features of the Prestige.

High Speed Internet Access

Your Prestige ADSL/ADSL2/ADSL2+ router can support downstream transmission rates of
up to 24Mbps and upstream transmission rates of 1 Mbps. Actual speeds attained depend on
ISP DSLAM environment.

Zero Configuration Internet Access

Once you connect and turn on the Prestige, 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 Prestige 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 Prestige without changing
the network settings (such as IP address and subnet mask) of the computer, when the IP
addresses of the computer and the Prestige are not in the same subnet.

Auto-provisioning

Your voice service provider can automatically update your Prestige’s configuration via an
auto-provisioning server.

Auto Firmware Upgrade

The Prestige gives you the option to upgrade to a newer firmware version if it finds one during
auto-provisioning. Your voice service provider must have an auto-provisioning server and a
server set up with firmware in order for this feature to work.

Firewall

The Prestige 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 Prestige firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.

Note: You can configure most features of the Prestige via SMT but we recommend

you configure the firewall and content filters using the web configurator.

42 Chapter 1 Getting To Know Your Prestige

Prestige 2602R Series User’s Guide

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
the Internet).

another network (for example a public IP address used on

Content Filtering

Content filtering allows you to block access to Internet web sites that contain key words (that
you specify) in the URL. You can also schedule when the Prestige should perform the filtering
and give trusted LAN IP addresses unfiltered Internet access.

REN

A Ringer Equivalence Number is used to determine the number of devices that may be
connected to the telephone line. The Prestige can support three devices per telephone port.

Dynamic Jitter Buffer

The Prestige has a built-in adaptive, buffer that helps to smooth out the variations in delay
(jitter) for voice traffic. This helps ensure good voice quality for your conversations.

Multiple SIP Accounts

The Prestige allows you to simultaneously use multiple voice (SIP) accounts and assign them
to one or both telephone ports.

Multiple Voice Channels

The Prestige can simultaneously handle multiple voice channels (telephone calls).
Additionally you can answer an incoming phone call on a VoIP account, even while someone
else is using the account for a phone call.

Voice Activity Detection/Silence Suppression

Voice Activity Detection (VAD) reduces the bandwidth that a call uses by not transmitting
when you are not speaking.

Comfort Noise Generation

The Prestige generates background noise to fill moments of silence when the other device in a
call stops transmitting because the other party is not speaking (as total silence could easily be
mistaken for a lost connection).

Echo Cancellation

The Prestige supports G.168, an ITU-T standard for eliminating the echo caused by the sound
of your voice reverberating in the telephone receiver while you talk.

Chapter 1 Getting To Know Your Prestige 43

Prestige 2602R Series User’s Guide

QoS (Quality of Service)

Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. The
Prestige supports Type of Service (ToS) tagging and Differentiated Services (DiffServ)
tagging. This allows the Prestige to tag voice frames so they can be prioritized over the
network.

SIP ALG

The Prestige is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass through
NAT for devices behind the Prestige (such as a SIP-based VoIP software application on a
computer).

Traffic Redirect

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

Universal Plug and Play (UPnP)

Using the standard TCP/IP protocol, the Prestige 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 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.

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.

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 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.

44 Chapter 1 Getting To Know Your Prestige

Prestige 2602R Series User’s Guide

Multiple PVC (Permanent Virtual Circuits) Support

Your Prestige supports up to 8 PVC’s.

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)

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.

Other PPPoE Features

• PPPoE idle time out

• PPPoE dial on demand

Packet Filters

The Prestige's packet filtering function allows added network security and management.

Ease of Installation

Your Prestige is designed for quick, intuitive and easy installation.

Housing

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

1.2 Applications for the Prestige

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

Chapter 1 Getting To Know Your Prestige 45

Prestige 2602R Series User’s Guide

1.2.1 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 (Digital Subscriber Line Access Multiplexer) providers. A DSLAM is a rack of
ADSL line cards with data multiplexed into a backbone network interface/connection (for
example, T1, OC3, DS3, ATM or Frame Relay). Think of it as the equivalent of a modem rack
for ADSL. In addition, the Prestige allows wireless clients access to your network resources. A
typical Internet access application is shown below.

Figure 1 Prestige Internet Access Application

1.2.1.1 Internet Single User Account

For a SOHO (Small Office/Home Office) environment, your Prestige offers the Single User
Account (SUA) feature that allows multiple users on the LAN (Local Area Network) to access
the Internet concurrently for the cost of a single IP address

1.2.2 Making Calls via Internet Telephony Service Provider

In a home or small office environment, you can use the Prestige to make and receive VoIP
telephone calls through an Internet Telephony Service Provider (ITSP).

The following figure shows a basic example of how you would make a VoIP call through an
ITSP. You use your analog phone (A in the figure) and the Prestige (B) changes the call into
VoIP. The Prestige then sends your call to the Internet and the ITSP’s SIP server. The VoIP call
server forwards calls to PSTN phones (E) through a trunking gateway (D) to the PSTN
network. The VoIP call server forwards calls to IP phones (F) through the Internet.

46 Chapter 1 Getting To Know Your Prestige

Figure 2 Internet Telephony Service Provider Application

1.2.3 Make Peer-to-peer Calls

Use the Prestige to make a call to the recipient’s IP address without using a SIP proxy server
Peer-to-peer calls are also called “Point to Point” or “IP-to-IP” calls. You must know the
peer’s IP address in order to do this.

Prestige 2602R Series User’s Guide

The following figure shows a basic example of how you would make a peer-to-peer VoIP call.
You use your analog phone (A in the figure) and the Prestige (B) changes the call into VoIP.
The Prestige then sends your call through the Internet to the peer VoIP device (C).

Figure 3 Peer-to-peer Calling

1.2.4 Firewall for Secure Broadband Internet Access

The Prestige 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.

This chapter describes how to configure LAN settings.

4.1 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.

4.1.1 LANs, WANs and the Prestige

Prestige 2602R Series User’s Guide

CHAPTER 4

LAN Setup

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 and the other outside the
WAN network as shown next.

Figure 23 LAN and WAN IP Addresses

4.1.2 DHCP Setup

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the Prestige
as a DHCP server or disable it. When configured as a server, the Prestige provides the TCP/IP
configuration for the clients. If you turn DHCP service off, you must have another DHCP
server on your LAN, or else the computer must be manually configured.

Chapter 4 LAN Setup 71

Prestige 2602R Series User’s Guide

4.1.2.1 IP Pool Setup

The Prestige is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool).
See the product specifications in the appendices. Do not assign static IP addresses from the
DHCP pool to your LAN computers.

4.2 DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address
and vice versa. The DNS server is extremely important because without it, you must know the
IP address of a 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 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 the LAN Setup screen 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
LAN Setup screen. 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.

4.3 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.

• 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.

72 Chapter 4 LAN Setup

• The Prestige acts as a DNS proxy when the Primary and Secondary DNS Server fields
are left blank in the LAN Setup screen.

4.4 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.

4.4.1 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.

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.

Prestige 2602R Series User’s Guide

4.5 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.

4.5.1 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 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.

Chapter 4 LAN Setup 73

Prestige 2602R Series User’s Guide

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.

4.5.1.1 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.

Note: 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.

4.5.2 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:

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

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

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

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

74 Chapter 4 LAN Setup

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.

4.5.3 Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1
recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to
a group of hosts on the network - not everybody and not just 1.

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC

2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between IGMP
version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is
used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address

224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address

224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts
(including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP.
The address 224.0.0.2 is assigned to the multicast routers group.

Prestige 2602R Series User’s Guide

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; WA N ).
Select None to disable IP multicasting on these interfaces.

4.6 Any IP

Traditionally, you must set the IP addresses and the subnet masks of a computer and the
Prestige to be in the same subnet to allow the computer to access the Internet (through the
Prestige). In cases where your computer is required to use a static IP address in another
network, you may need to manually configure the network settings of the computer every time
you want to access the Internet via the Prestige.

With the Any IP feature and NAT enabled, the Prestige allows a computer to access the
Internet without changing the network settings (such as IP address and subnet mask) of the
computer, when the IP addresses of the computer and the Prestige are not in the same subnet.
Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply
connect the computer to the Prestige and access the Internet.

Chapter 4 LAN Setup 75

Prestige 2602R Series User’s Guide

The following figure depicts a scenario where a computer is set to use a static private IP
address in the corporate environment. In a residential house where a Prestige is installed, you
can still use the computer to access the Internet without changing the network settings, even
when the IP addresses of the computer and the Prestige are not in the same subnet.

Figure 24 Any IP Example

The Any IP feature does not apply to a computer using either a dynamic IP address or a static
IP address that is in the same subnet as the Prestige’s IP address.

Note: You must enable NAT/SUA to use the Any IP feature on the Prestige.

4.6.1 How Any IP Works

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP
address) to a physical machine address, also known as a Media Access Control or MAC
address, on the local area network. IP routing table is defined on IP Ethernet devices (the
Prestige) to decide which hop to use,

The following lists out the steps taken, when a computer tries to access the Internet for the first
time through the Prestige.

1 When a computer (which is in a different subnet) first attempts to access the Internet, it

sends packets to its default gateway (which is not the Prestige) by looking at the MAC
address in its ARP table.

2 When the computer cannot locate the default gateway, an ARP request is broadcast on the

LAN.

3 The Prestige receives the ARP request and replies to the computer with its own MAC

address.

to help forward data along to its specified destination.

4 The computer updates the MAC address for the default gateway to the ARP table. Once

the ARP table is updated, the computer is able to access the Internet through the Prestige.

76 Chapter 4 LAN Setup

5 When the Prestige receives packets from the computer, it creates an entry in the IP

routing table so it can properly forward packets intended for the computer.

After all the routing information is updated, the computer can access the Prestige and the
Internet as if it is in the same subnet as the Prestige.

This chapter describes how to configure WAN settings.

5.1 WAN Overview

A WAN (Wide Area Network) is an outside connection to another network or the Internet.

5.1.1 Encapsulation

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

Prestige 2602R Series User’s Guide

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 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 appendices.

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 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.

Chapter 5 WAN Setup 79

Prestige 2602R Series User’s Guide

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 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.

5.1.4 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.

5.1.4.1 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.

80 Chapter 5 WAN Setup

Prestige 2602R Series User’s Guide

5.1.4.2 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.

5.1.4.3 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.

5.1.5 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

5.2 Metric

The metric represents the "cost of transmission". A router determines the best route for
transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the
measurement of cost, with a minimum of "1" for directly connected networks. The number
must be between "1" and "15"; a number greater than "15" means the link is down. The
smaller the number, the lower the "cost".

The metric sets the priority for the Prestige’s routes to the Internet. If any two of the default
routes have the same metric, the Prestige uses the following pre-defined priorities:

• Normal route: designated by the ISP (see Section 5.6 on page 83)

• Traffic-redirect route (see Section 5.7 on page 86)

For example, if the normal route has a metric of "1" and the traffic-redirect route has a metric
of "2" and dial-backup route has a metric of "3", then the normal route acts as the primary
default route. If the normal route fails to connect to the Internet, the Prestige tries the traffic­redirect route next. In the same manner, the Prestige uses the dial-backup route if the traffic­redirect route also fails.

If you want the dial-backup route to take first priority over the traffic-redirect route or even the
normal route, all you need to do is set the dial-backup route’s metric to "1" and the others to
"2" (or greater).

Chapter 5 WAN Setup 81

Prestige 2602R Series User’s Guide

IP Policy Routing overrides the default routing behavior and takes priority over all of the
routes mentioned above (see

Chapter 36 on page 335).

5.3 PPPoE Encapsulation

The Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband
modem (DSL, cable, wireless, etc.) connection. The PPPoE option is for a dial-up connection
using PPPoE.

For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for example Radius).

One of the benefits of PPPoE is the ability to let you access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily
create and offer new IP services for individuals.

Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires
no specific configuration of the broadband modem at the customer site.

By implementing PPPoE directly on the Prestige (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the Prestige does that part
of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

5.4 Traffic Shaping

Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average
rate and fluctuations 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 832Kbps 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 each bursty traffic source. It specifies the
maximum average rate at which cells can be sent over the virtual connection. SCR may not be
greater than the PCR.

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.

82 Chapter 5 WAN Setup

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

Figure 26 Example of Traffic Shaping

5.5 Zero Configuration Internet Access

Prestige 2602R Series User’s Guide

Once you turn on and connect the Prestige to a telephone jack, 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
Prestige cannot connect to the ISP, you will be redirected to web screen(s) for information
input or troubleshooting.

Zero configuration for Internet access is disabled when

• the Prestige is in bridge mode

• you set the Prestige to use a static (fixed) WAN IP address.

Figure 28 Traffic Redirect Example

The following network topology allows you to avoid triangle route security issues when the
backup gateway is connected to the LAN. Use IP alias to configure the LAN into two or three
logical networks with the Prestige itself as the gateway for each LAN network. Put the
protected LAN in one subnet (Subnet 1 in the following figure) and the backup gateway in
another subnet (Subnet 2). Configure filters that allow packets from the protected LAN
(Subnet 1) to the backup gateway (Subnet 2).

Metric This field sets this route's priority among the routes the Prestige uses.

The metric represents the "cost of transmission". A router determines the best route
for transmission by choosing a path with the lowest "cost". RIP routing uses hop
count as the measurement of cost, with a minimum of "1" for directly connected
networks. The number must be between "1" and "15"; a number greater than "15"
means the link is down. The smaller the number, the lower the "cost".

Network Address Translation

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.

Prestige 2602R Series User’s Guide

CHAPTER 6

(NAT) Screens

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 18 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.

Chapter 6 Network Address Translation (NAT) Screens 91

Prestige 2602R Series User’s Guide

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

6.1.3 How NAT Works

Table 19 on page 94),

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.

92 Chapter 6 Network Address Translation (NAT) Screens

Figure 31 How NAT Works

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.

Prestige 2602R Series User’s Guide

Figure 32 NAT Application With IP Alias

6.1.5 NAT Mapping Types

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

Chapter 6 Network Address Translation (NAT) Screens 93

Prestige 2602R Series User’s Guide

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

• 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).

• Many to Many Overload: In Many-to-Many Overload mode, the Prestige maps the
multiple local IP addresses to shared global IP addresses.

• 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.

• 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.

M:M Ov

M:M No OV

Server

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 19 on page 94.

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

94 Chapter 6 Network Address Translation (NAT) Screens

• 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.

Prestige 2602R Series User’s Guide

6.3.1 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 an IP address in Server Set 1 (default server) the Prestige discards all
packets received for ports that are not specified here or in the remote management setup.

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 6.
