1 Introduction

Congratulations on your purchase of the ZyXEL Prestige 128L IDSL
Router. The Prestige integrates a Router and Bridge, offering
inexpensive yet complete telecommunications and internetworking
solutions for your home or branch office. The Prestige is ideal for
everything from Internet access, to receiving calls from Remote Dial-in
Users, to making LAN-to-LAN connections to Remote Nodes.

Distinguishing features of the Prestige 128L include support for a full
range of networking protocols such as TCP/IP (Transmission Control
Protocol/Internet Protocol), Novell IPX (Internet Packet Exchange),
and Transparent Bridging. The complete solution also includes extensive
Network Management, and solid security features.

Features

The Prestige is packed with a number of features that give it the
flexibility to provide a complete networking solution for Internet access
and business users.

Ease of Installation

The Prestige is a self-contained unit that is quick and easy to install.
Physically, it resembles an external modem except for the fact that it is a
router and uses an Ethernet cable to connect to the host network.

Introduction 1

ISDN Digital Subscriber Line (IDSL)

IDSL uses the 2B1Q line coding standard for ISDN BRI circuits. Used
for data-only applications, IDSL can use unshielded twisted pair wire
for transmitting data at 64/128Kbps for up to 18,000 feet.

The differences between IDSL and ISDN are:

1. ISDN passes through the phone company's central office voice
network; IDSL bypasses it by plugging into a special router at the
phone company end. Or a pair of Prestige 128L’s can be
connected by a single twisted pair cable.

2. ISDN requires call setup; IDSL is a dedicated service.

Multiple Networking Protocol Support

The Prestige 128L is a multi-protocol router. It supports TCP/IP,
Novell IPX and Transparent Bridging.

Full Network Management

The Prestige 128L incorporates SNMP (Simple Network Management
Protocol ) support and menu-driven network management via an RS­232 or Telnet connection.

2 Introduction

PPP Security

The Prestige 128L supports PAP (Password Authentication Protocol)
and CHAP (Challenge Handshake Authentication Protocol ).

Dynamic Host Configuration Protocol (DHCP)

DHCP allows you to dynamically and automatically assign IP address
settings to hosts on your network.

Data Compression

The Prestige incorporates Stac data compression and Compression
Control Protocol.

Applications For Your Prestige

Some applications for your Prestige include:

Internet Access

The Prestige supports TCP/IP protocol. It is also compatible with other
IDSL access servers manufactured by vendors such as Ascend.

Internet Single User Account (SUA)

For a small office environment, the Prestige SUA support. This allows
multiple users to access the LAN simultaneously using a single IP
address.

SUA address mapping can also be used for LAN to LAN connections.

Multiprotocol LAN-to-LAN Connection

The Prestige 128L can connect to another Prestige 128L-like router to
link two different LANs. The Prestige 128L supports TCP/IP and
Novell IPX routing, and has the capability to bridge any Ethernet
protocol.

Introduction 5

6 Introduction

2 Before You Begin

To ensure successful installation of your Prestige, we strongly
recommend that you carefully follow the steps outlined in Chapters 2
and 3. These chapters are designed as a guide for you to collect all
necessary information about your LAN. Once this information has been
collected, it will be used to configure your Prestige.

After you have successfully configured your Prestige, see the
appropriate chapters to setup your application.

Road Map and Flow

The chart below is provided as a step by step guide to successful
installation your Prestige.

Before You Begin 7

Figure 2-1 Installation Guide

Completing the Worksheet

Before you continue, locate the worksheet at the end of this chapter.
This information worksheet has been provided to help you get through
setup and installation of your Prestige as easily as possible.

Ordering Your IDSL Line

There is no need to order an IDSL line if you are using a pair of
Prestige 128Ls directly connected by a twisted pair cable. If you
choose to use IDSL, you will need to contact your local telephone
company and order IDSL leased service to connect two IDSL routers.

8 Before You Begin

Collecting General Setup Information

Your Prestige requires the following system information. You can obtain
all the pertinent information from your network administrator. Record
this information into the worksheet as it becomes available. This
worksheet will later be referred to as you configure your Prestige.

• System Name - This is the name given to your Prestige for
identification purposes. This name should be no more than 8
alphanumeric characters. Spaces are not allowed, but “-” and “_”
are accepted. This name can be obtained remotely via the SNMP
management protocol and will be displayed as the prompt when the
user enters the Command Mode.

• Route IP Field - For Internet access, you will need to enable the
Route IP Field. See Chapter 4 for more details on configuring your
Prestige for Internet access. To support Novell IPX, or Bridging,
enable the appropriate protocol and reference the related chapters
for detailed information.

You have now collected all of the general setup information you need.
Make sure that you have entered all the values onto the worksheet
before proceeding to the next section.

Collecting IDSL Information

• Service Type - There are two options: Client or Server. One
IDSL router should be set as the client, and the other as server.

• Transfer Type - There are two options: Leased 128 or Leased

64. The data will be transmitted in 128Kbps if Leased128 is
selected; otherwise, it will be transmitted in 64Kbps. The transfer
type must be set the same for both the client and server router.

Before You Begin 9

Collecting Ethernet Setup Information

This section assumes that you are setting up your Prestige for a TCP/IP
connection. If you want to configure the Prestige for other protocols
(e.g., IPX), refer to the appropriate chapters.

• Ethernet Interface - The first step is to determine the type of
Ethernet interface you will be using. There are two options: AUI or
UTP. Record the interface type onto the worksheet. If you have a
10Base2 (BNC), you should choose AUI.

• IP Address - An IP Address is required for TCP/IP protocol. The
IP Address is the unique 32-bit number assigned to your Prestige.
This address is written in dotted decimal notation (four 8-bit
numbers, between 0 and 255, separated by periods), e.g.,

192.68.203.5.

Record the IP Address into the worksheet as assigned by your

network administrator. Note that every machine on an internet must
have a unique IP address - do not assign an arbitrary address to
any machine.

• IP Sub-net Mask - This field is required for TCP/IP protocol. An
IP address consists of two parts, the network ID and the host ID.
The IP Subnet Mask is used to specify the network ID portion of
the address, expressed in dotted decimal notation. The Prestige will
automatically calculate this mask based on the IP address that you
assign. Unless you have special need for subnetting, use the default
mask.

The table below lists some examples of IP subnet masks and the
number of hosts that are allowed. Consult your network administrator if
you are unsure of this value.

This chapter outlines how to connect your Prestige to the LAN and
IDSL line. Refer to the diagram below to identify all of the ports on
your device when you attempt to make the various connections.

Figure 3-1 Rear Panel Diagram

A Warning On Connection Cables

The IDSL line and Ethernet cable, are very similar to each other. It is
important that you use the correct cable for each connection; otherwise,
your Prestige could be damaged.

Installation 15

Connecting Your Computer and Your Prestige

For the initial setup of your Prestige, use the provided RS-232 cable
and communications software to configure your Prestige.

After your Prestige has been successfully installed, you can modify the
configuration through a remote Telnet connection. See Chapter 12 for
detailed instructions on using Telnet to configure your Prestige.

Connecting the RS-232 Cable to your Prestige

One 9-25 pin adapter is included with your Prestige. To connect a RS­232 cable, connect the 9-pin end of the cable to the DTE port on the
back panel of the Prestige. Connect the other end to the RS-232 cable
connected to the serial port (COM1, COM2, or any other COM port)
of your computer.

Connecting an IDSL Line to your Prestige

Plug one end of the IDSL line included in your package into the socket
on the rear panel of your Prestige labeled Line, and the other end into
the IDSL wall jack or another Prestige.

O NOTE: THE IDSL JACK IS FOR IDSL LINE CONNECTION ONLY. CONNECTION OF A

PHONE LINE MAY RESULT IN DAMAGE TO YOUR PRESTIGE.

ATTENTION: LA FICHE IDSL EST DESTINÉE UNIQUEMENT POUR LA CONNEXION SUR UNE

LIGNE RNIS. LA CONNEXION SUR UNE LIGNE TÉLÉPHONIQUE PEUT
ENDOMMAGER VOTRE ADAPTATEUR DE TERMINAL.

Connecting an Ethernet Cable to your Prestige

Your Prestige supports two types of Ethernet connections. The
connection procedure differs for each one; follow the one that is
appropriate for your installation.

UTP

16 Installation

The UTP port is used to connect to a 10Base-T network. 10Base-T
networks use Unshielded Twisted Pair (UTP) cable and RJ-45
connectors that look like a bigger telephone plug with 8 pins. Two types
of gray Ethernet cables come with the package:

• Straight through cable (white tag): Connect your Prestige 128L

to a 10Base-T hub.

• Crossover cable (red tag): Connect your Prestige to your

computer directly without a hub.

O NOTE: IF THIS CABLE IS USED TO CONNECT IDSL, IT MAY DAMAGE YOUR PRESTIGE.

AUI
The AUI port (the connector with 15 pins) is used to connect your

Prestige to a 10Base5 (thicknet) network.
If you have a 10Base2 network using BNC connectors and thin coaxial

cables, you will need a transceiver between the AUI port and the
10Base2 cabling.

Connecting the Power Adapter to your
Prestige

Plug the 16VAC 1000mA power adapter into the outlet on the rear
panel of the Prestige labeled POWER.

At this point, you should have connected the RS-232 cable, the ISDN
phone line, the Ethernet cable, and the power supply. You can now
power on your Prestige.

you are using and select the appropriate option.

2. Input and Output Filter Sets - Filter sets are used to block
certain packets to reduce traffic and to prevent a security breach.
Filtering is a very involved subject, so leave these fields blank for
the time being. After you have studied filtering in Chapter 9, come
back and define the filter sets.

TCP/IP Ethernet Setup and DHCP

If you are setting up your network for the first time, read Chapter 4,
Configuring for Internet Access, before proceeding. The chapter
contains important information on how to assign IP addresses for your
network.

From Menu 3 - Ethernet Setup, enter 2 to go to Menu 3.2 - TCP/IP
Ethernet Setup.

26 Installation

Figure 3-8 Menu 3.2 - TCP/IP Ethernet Setup

1. DHCP - This field determines what mode of DHCP (Dynamic
Host Configuration Protocol) support your Prestige should use. If
set to None, DHCP will not be used. If set to Server, your Prestige

will act as a DHCP server, capable of automatically assigning IP
addresses to Windows 95, Windows NT, and other systems that
support the DHCP client. When DHCP is used, the following four
items need to be set.

Do not set this field to Server if there is already a DHCP server on

your network.

2. Client IP Pool Starting Address - DHCP can assign IP
addresses to hosts dynamically instead of requiring that each system
have a fixed IP address. IP addresses are allocated from a block of
addresses, usually assigned by your Internet provider. The Client IP
Pool Starting Address gives the first address in the reserved block,
which is also used as the LAN network address of your Prestige.
This address will also serve as the default gateway for DHCP
clients.

3. Size of Client IP Pool - Gives the size of the block of addresses
reserved for DHCP address assignment. Your Prestige uses the first
address in the block, and the remaining addresses in the pool are
assigned to clients.

4. Primary DNS Server/Secondary DNS Server - These two
fields are used by DHCP clients (such as Windows 95 and
Windows NT systems) for Domain Name Servers. Usually your
Internet provider will provide one or more name service hosts.

5. IP Address - Enter the IP address of your Prestige in dotted
decimal notation (four 8-bit numbers, between 0 and 255,
separated by periods), e.g., 192.68.135.5. Note that every
machine on the TCP/IP network must have a unique IP address.

6. IP Subnet Mask - An IP address consists of two parts, the
network ID and the host ID. The IP Subnet Mask is used to specify
the network ID portion of the address, expressed in dotted decimal
notation. Your Prestige will automatically calculate this mask based

Installation 27

on the IP address that you assign. Unless you have special need for
subnetting, use the default subnet mask calculated by your Prestige.

7. RIP Direction - This parameter determines how your Prestige
handles RIP (Routing Information Protocol). If set to Both (default),
your Prestige will broadcast its routing table on the LAN, and
incorporate RIP broadcasts by other routers into its routing table. If
set to In Only, your Prestige will not broadcast its routing table on
the LAN, if set to Out Only, your Prestige will broadcast its routing
table but ignores any RIP broadcast packets that it receives. If set
to None, your Prestige will not participate in any RIP exchange with
other routers.

Usually, you should leave this parameter at its default of Both and

let RIP propagate the routing information automatically.

8. RIP: Version - This parameter determines the format of the RIP
packets used to exchange routing information. The choices are RIP­1, RIP-2B, and RIP-2M. The table below gives a brief description
of your choices:

RIP-1: Accept and send RIP-1 messages only.

28 Installation

RIP-2B: accept RIP-1 and RIP-2 messages (both

broadcast and multicast), and send RIP-2
messages in broadcast format.

RIP-2M: accept RIP-1 and RIP-2 messages (both

broadcast and multicast), and send RIP-2
messages in multicast format.

The suggested choice for this field is RIP-2B. Select RIP-1 if your

Prestige is in an environment with other routers or workstations
which have problems with RIP-2 broadcast packets. Select RIP­2M only if it is in a pure RIP-2 environment.

4 Configuring for Internet

Access

Menu 4 of the SMT allows you to configure Internet access on one
screen. Before you configure your Prestige for Internet access, you
need to collect the following information from your ISP (Internet
Service Provider).

• IP address of the ISP’s gateway (optional).

• Login name (optional).

• Password (optional).

For your Workstation:

• Domain Name Server (DNS)

Figure 4-1 Internet Access

Configuring for Internet Access 31

IP Addresses and the Internet

Conventionally, the Internet (with a capital I) refers the large-scale
interconnected networks across the world that was originally developed
by the US Department of Defense. The Internet uses exclusively the
TCP/IP suite of protocols. The term “internet” (lower case i), however,
refers to any interconnected networks using any protocol. An internet
can be as simple as two hosts on a LAN, or it can be as complex as the
Internet itself.

Every machine on the Internet must have a unique address within that
internet. If your networks are isolated from the Internet, e.g., 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

For this reason, it is recommended that you choose your network
number from the above list.

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

O NOTE: REGARDLESS OF YOUR PARTICULAR SITUATION, DO NOT CREATE AN

ARBITRARY IP ADDRESS; ALWAYS FOLLOW THE GUIDELINES ABOVE. FOR MORE
INFORMATION ON ADDRESS ASSIGNMENT, REFER TO RFC 1597, ADDRESS

32 Configuring for Internet Access

ALLOCATION FOR PRIVATE INTERNET’S AND RFC 1466, GUIDELINES FOR
MANAGEMENT OF IP ADDRESS SPACE.

Once you have determined the IP address range for your local network,
you may want to use DHCP (Dynamic Host Configuration Protocol) to
assign addresses to individual hosts on the network, as an alternative to
manually configuring each host’s IP settings. See the TCP/IP Ethernet
Setup and DHCP section on page 26 for more information about
DHCP.

Internet Access Configuration

The following steps describe the set-up procedure to configure your
Prestige for Internet access. The information you will need to provide
will be indicated in bold type.

Figure 4-2 Menu 4 - Internet Access Setup

1. From the Main Menu, enter 4 to go to Menu 4 - Internet Access
Setup as seen above.

2. ISP’s Name - Enter the name of your Internet Service Provider,
e.g., myisp. This information is for identification purposes only.

Configuring for Internet Access 33

3. ISP IP Addr - Enter the IP Address of the remote gateway at the
ISP’s site. If you do not have this data, just leave it blank.

4. My Login Name - Enter the login name provided by your ISP.

5. My Password - Enter the password associated with the login name
above. Note that this login name/password pair is only for your
Prestige to connect to the ISP’s gateway. When you use TCP/IP
applications, e.g., FTP, to access the Internet from your
workstation, you will need a separate login name and password for
each server.

6. Single User Account - See the following section for a more
detailed discussion on the Single User Account feature. The default
is No.

7. Press ENTER at the message: Press ENTER to Confirm ... to
confirm your selections, or press ESC at any time to cancel your
selections.

8. At this point, the SMT will ask if you wish to test the Internet
connection. If you select Yes, your Prestige will call the ISP to test
the Internet connection. If the test fails, note the error message that
you receive and take the appropriate troubleshooting steps.

Single User Account

Typically, if there are multiple users on the LAN wanting to concurrently
access the Internet, they will have to subscribe to multiple IP addresses
or a Class C subnetwork from the ISP. In either case, these two
approaches will cost more than a single user account.

The Single User Account (SUA) feature allows customers to have the
same benefits as having a Class C address, but still only pay for one IP
address, thus saving significantly on subscription fees. (Check with your
ISP before you enable this feature).

34 Configuring for Internet Access

This feature may also be used to connect to TCP/IP remote nodes
other than Internet Service Providers. For example this feature can be
used to simplify the allocation of IP addresses when connecting branch
offices to the corporate network.

The IP address for the Single User Account can be either fixed or
dynamically assigned by the ISP (or other remote node). In addition,
you can also configure a server, e.g., a Web server, on your local
network and make it accessible by outside users.

If you do not set a server IP address, SUA offers the additional benefit
of firewall protection. This is because if no server is defined, all
incoming inquiries will be filtered out by your Prestige even if you do
have a server on your network. This can prevent intruders from probing
your system.

Your Prestige accomplishes this address sharing by translating the
internal LAN IP addresses to a single address that is globally unique on
the Internet. For more information on IP address translation, refer to
RFC 1631, The IP Network Address Translator (NAT).

In summary:

• SUA is an ideal, cost-effective solution for small offices with less
than 20 hosts using a LAN to concurrently access the Internet or
other remote TCP/IP network.

• SUA can provide one server address to be accessed by Remote
Dial -in Users, thus controlling the incoming packets.

• SUA can provide firewall protection if you do not configure a
server IP address. All incoming inquiries will be filtered out by your
Prestige. Therefore, servers on your network are protected.

Configuring for Internet Access 35

• UDP and TCP datagrams can be routed. In addition, ICMP echo
can also be routed.

The figure below shows an example of a small office connected to the
Internet via a Single User Account using your Prestige. Note that if you
enable the Single User Account feature, your local IP address MUST
be selected from the list of IP addresses for private networks as defined
by the IANA.

Figure 4-3 A Single User Account Using the Prestige

Configuration for Single User Account

The steps for configuring your Prestige for Single User Internet Access
are identical to conventional Internet access with the exception that you
need to fill in three extra fields.

Follow steps 1-8 from the previous section, Internet Access
Configuration .

1. Single User Account - Enter Yes to enable the Single User
Account feature. Use the space bar to toggle between Yes and No.

2. Single User Account: IP Addr - If your ISP assigns you a
dynamic IP address, enter 0.0.0.0 here. If your ISP assigns you a

36 Configuring for Internet Access

static IP address enter that IP address here. You have to use a
static IP address if you are using a pair of Prestiges.

3. Single User Account: Server IP Addr - If you want to make a
single server, e.g., a Web server, accessible to outside users, enter
that server’s IP address here.

Press ENTER at the message: Press ENTER to Confirm ... to

confirm your selections or press ESC at any time to cancel your
selections.

At this point, your Prestige will ask if you wish to test the Internet

connection. If you select Yes, the Prestige will call the ISP to test
the Internet connection. If the test fails, note the error message that
you receive and take the appropriate troubleshooting steps.

5 Remote Node Configuration

A Remote Node represents both a remote gateway and the internet
behind it, across an IDSL connection. A Remote Node is required for
connecting to the remote network directly. Note that when you use
Menu 4 to configure the Internet, your Prestige will automatically add a
Remote Node for you.

Even though you can configure up to four remote nodes, the first active
remote node will be used to connect to the remote LAN. It is a good
practice to keep only one active remote node for your Prestige.

In this chapter, we will discuss the parameters that are protocol
independent. The protocol dependent configuration will be covered in
subsequent chapters. For TCP/IP, see Chapter 6. For IPX, see
Chapter 7. For bridging, see Chapter 8.

From the Main Menu, enter 11 to go to Menu 11 - Remote Node
Setup. When in menu 11, enter the number of the Remote Nodes (1 to

4) that you wish to configure as shown below:

Remote Node Configuration 39

Figure 5-1 Menu 11 - Remote Node Setup

Enter the Remote Node number to edit and you will go to the next
submenu: 11.1 - Remote Node Profile as shown below:

Figure 5-2 Menu 11.1 - Remote Node Profile

1. Rem Node Name - This is a required field. Enter a descriptive
name for the Remote Node, e.g., SJHQ. This field can support up
to eight characters. This name must be unique from any other
Remote Node name or Remote Dial-in User name.

40 Remote Node Configuration

2. Active - Press the space bar to toggle between Yes and No. When
a Remote Node is deactivated, it has no effect on the operation of
your Prestige, even though it is still kept in the database and can be
activated in the future. Deactivated nodes are displayed with a ­(minus sign) at the beginning of the name in Menu 11.

3. Incoming: Rem Node Login Name - Enter the login name that
this Remote Node will use when it calls into your Prestige. The login
name in this field combined with the Rem Node Password will be
used to authenticate the incoming calls from this node.

4. Incoming: Rem Node Password - Enter the password used when
this Remote Node calls into your Prestige.

5. Outgoing: My Login Name - This is a required field if Call
Direction is either Both or Out. Enter the login name for your
Prestige when it calls this Remote Node.

6. Outgoing: My Password - This is a required field if Call Direction
is either Both or Out. Enter the password for your Prestige when it
calls this Remote Node.

7. Outgoing: Authen - This field sets the authentication protocol used
for outgoing calls.

Your Prestige supports two authentication protocols: PAP

(Password Authentication Protocol ) and CHAP (Challenge
Handshake Authentication Protocol).

• PAP sends the user name and password in plain text.

• CHAP scrambles the password before it is sent over the wire.

Generally speaking, CHAP is more secure than PAP; however,

PAP is readily available on more platforms. The recommendation is
to use CHAP whenever possible. Turning off the authentication is
STRONGLY discouraged.

Options for this field are:

Remote Node Configuration 41

• CHAP/PAP - Your Prestige will try CHAP when CHAP is

requested by the Remote Node or PAP when PAP is
requested by the Remote Node.

• CHAP - Use CHAP only.

• PAP - Use PAP only.

8. Route - This field determines the protocols that your Prestige will
route. The choices for this field are determined by the features that
are enabled.

9. Bridge - Bridging is used for protocols that are not supported or
not turned on in the previous Route field, e.g., SNA. When bridging
is enabled, your Prestige will forward any packet that it does not
recognize to this Remote Node; otherwise, the unrecognized
packets are discarded. The disadvantage of bridging is that it usually
generates large amounts of traffic. Press the space bar to select
either Yes or No.

10. Edit PPP Options - To edit the PPP options for this Remote
Node, move the cursor to this field, use the space bar to select Yes
and press ENTER. This will bring you to Menu 11.2 - Remote
Node PPP Options For more information on configuring PPP
options, see the section Editing PPP Options.

11. IP Addr - This is a required field if Route is set to IP. Enter the IP
address of this Remote Node.

12. Edit IP/IPX/Bridge Options - To edit the parameters of the
protocols, go to this field, select Yes and press ENTER. This will
bring you to Menu 11.3 - Remote Node Network Layer Options.
For more information on filling out this screen, refer to the chapter
pertaining to your specific protocol.

13. Session Option: Input Filter Sets and Output Filter Sets - In
these fields, select which filter set(s) you would like to implement to
filter the incoming and outgoing traffic between this Remote Node

42 Remote Node Configuration

and your Prestige. You can choose from 12 different filter sets. In
addition, you can link up to 4 filter sets together for further
customization (e.g., 1, 5, 9, 12). Note that spaces and , are
accepted in this field.

For more information on customizing your filter sets, see Chapter 9.

The default is blank, i.e., no filters defined.

14. Session Option: Idle Timeout (sec) - This value specifies the
number of idle seconds that elapses before sending a ppp-echo
packet to verify whether the line is up.

Once you have completed filling in Menu 11.1 - Remote Node Profile,
press ENTER at the message: Press ENTER to Confirm ... to confirm
your selections, or press ESC at any time to cancel your selections.

6 TCP/IP Configuration

This chapter shows you how to configure your Prestige for TCP/IP.

Depending on your particular applications, you will need to
configure different menus. For instance, Internet access is the most
common application of TCP/IP. For this application, you should
configure Menu 4. We will illustrate the configuration for other
applications in the following sections.

IP Subnet Mask

A subnet mask is a 32-bit quantity that, when logically ANDed with an
IP address, yields the network number. For instance, the subnet masks
for class A, B and C without subnetting are 255.0.0.0, 255.255.0.0
and 255.255.255.0, respectively.

To create more network numbers, you shift some bits from the host ID
to the network ID. For instance, to partition a class C network number

192.68.135.0 into two, you shift 1 bit from the host ID to the network

ID. Thus the new subnet mask will be 255.255.255.128; the first
subnet will have network number 192.68.135.0 with hosts

192.68.135.1 to 192.68.135.126 and the second subnet will have

network number 192.68.135.128 with hosts 192.68.135.129 to

192.68.135.254.

It is recommended that you use the same subnet mask for all physical
networks that share an IP network number. The table below lists the
additional subnet mask bits in dot decimal notations. To use to following
table, write down the original subnet mask and substitute the higher
order 0s with the dot decimal of the additional subnet bits. For instance,

TCP/IP Configuration 45

to partition your class C network 204.247.203.0 with subnet mask

255.255.255.0 into 16 subnets (4 bits), the new subnet mask becomes

255.255.255.240.

LAN-to-LAN Application

A typical LAN-to-LAN application is to use your Prestige to call from
a branch office to the headquarters, as depicted in the following
diagram.

For the branch office, you need to configure a Remote Node in order to
dial out to the headquarters. Additionally, you may also need to

46 TCP/IP Configuration

Figure 6-1 LAN-to-LAN Application

configure Static Routes if some services reside beyond the immediate
remote LAN.

Remote Node Setup

Follow the procedure in Chapter 5 to fill the protocol-independent

parameters in Menu 11, Remote Node Profile. For the protocol­dependent parameters, follow the instructions below.

1. Route - Make sure IP is among the protocols in the Route field.

2. IP Address - Enter the IP address of the gateway at the remote
site (in this case, headquarters). If the remote router is using a
different IP address than the one entered here, your Prestige will
drop the call.

Edit IP/IPX/Bridge - Press the space bar to change it to Yes and
press Enter to go to the Menu 11.3 - Remote Node Network Layer
Options menu shown below:

Figure 6-2 Menu 11.3 - Remote Node Network Layer Options

1. Rem IP Address - This will show the IP address you entered for
this Remote Node in the previous menu.

TCP/IP Configuration 47

2. Rem IP Subnet Mask - Enter the subnet mask for the remote
network.

3. My WAN Addr - Some implementations, especially the UNIX
derivatives, require hosts on both ends of the ISDN link to have
separate addresses from the LAN, and that the addresses must
have the same network number. If this is the case, enter the IP
address assigned to the WAN port of your Prestige. Note that this
is the address assigned to the local Prestige, not the remote router.

Figure 6-3 Sample IP Addresses

4. Single User Account - This field should be set to yes to enable the
Single User Account (Network Address Translation) feature for this
site. Use the space bar to toggle between yes and no.

5. Server IP address - If you are using the Single User Account
feature and you want to make a server accessible on your LAN,
e.g., a web server, accessible to outside users, enter that servers IP
address here.

6. Metric - The metric represents the “cost” of transmission for
routing purpose. IP routing uses hop count as the measurement of
cost, with a minimum of 1 for directly connected networks. Enter a
number that approximates the cost for this link. The number need

48 TCP/IP Configuration

not be precise, but it must be between 1 and 16. In practice, 2 or 3
is usually a good number.

7. Private - This parameter determines if your Prestige will include the
route to this Remote Node in its RIP broadcasts. If set to yes, this
route is kept private and not included in RIP broadcast. If no, the
route to this Remote Node will be propagated to other hosts
through RIP broadcasts.

8. RIP - This parameter determines how your Prestige handles RIP
(Routing Information Protocol), and the default is Both. If set to
Both, your Prestige will broadcast its routing table on the WAN,
and incorporate RIP broadcasts by the other router into its routing
table. If set to In Only, your Prestige will not broadcast its routing
table on the WAN; if set to Out Only, your Prestige will broadcast
its routing table but ignores any RIP broadcast packets that it
receives. If set to None, your Prestige will not participate in any
RIP exchange with other routers. Usually, you should leave this
parameter at its default of Both and let RIP propagate the routing
information automatically.

Once you have completed filling in the Network Layer Options Menu,
press ENTER to return to Menu 11. Press ENTER at the message:
Press ENTER to Confirm ... to save your selections, or press ESC at
any time to cancel your selections.

Static Route Setup

On a directly connected internet, RIP usually handles the routing
automatically. However, RIP cannot propagate across isolated
networks, as in the case before a connection is made between the two
subnetworks using one Class C IP address. Without a route, no
packets can be forwarded to their destinations. A static route is used to
resolve this problem by providing your Prestige with some static routing
information. As a matter of fact, when you configure the Internet Access

TCP/IP Configuration 49

or a Remote Node, a static route is implicitly created by your Prestige.
An example is given below. In the example, stations on the

204.5.1.0/24 subnetwork can access the remote stations using the static

route. The route will have a destination of 204.5.1.64/26 with the
gateway address being that of the Remote Node (204.5.1.150).

Figure 6-4 Static Routing Example

Note that in normal circumstances, your Prestige will have adequate
routing information after you configure the Internet access and Remote
Nodes; you do not need to configure additional static routes. You will
need to configure static routes only for unusual cases, e.g., subnetting.
To create additional static routes for IP, use Menu 12, Static Route
Setup as shown below:

50 TCP/IP Configuration

Figure 6-5 Menu 12 - Static Route Setup - Main Menu

Figure 6-6 IP Static Route Setup

1. Route Name - Enter a descriptive name for this route. This is for
identification purpose only.

2. Active - This fields allows you to activate/deactivate this static
route.

3. 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,

TCP/IP Configuration 51

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.

4. IP Subnet Mask - Enter the subnet mask for this destination.
Follow the discussion on IP subnet mask in this chapter.

5. Gateway IP Address - Enter 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 ISDN,
the gateway must be the IP address of one of the Remote Nodes.

6. The Metric and the Private parameters have the same meaning as
those in the Remote Node Setup.

message: Press ENTER to Confirm ... to save your selections, or press
ESC at any time to cancel your selections.

7 Novell IPX Configuration

This chapter shows you how to configure your Prestige for IPX.

Depending on your particular applications, you will need to
configure different menus. We will illustrate the configuration for
some applications in the following sections.

IPX Network Environment

Frame Type

The stations on an IPX network (both clients and servers) can run on
four different frame types existing on one physical Ethernet cable. These
frame types include 802.2, 802.3, Ethernet II (DIX), and SNAP.

Network Numbers

Whenever you are setting up an IPX routing environment, it is important
to correctly configure the network numbers on the LAN. On any IPX
network, there is an external network number that is, the number
associated with the frame type on the Ethernet cable to which the
stations on the network are joined. In addition to this external network
number, each NetWare server has its own internal network number. It
is important to remember that every network number has to be unique
for that entire internetwork. So if a server station had an internal
network number of 00000011, there is no other network number
(internal or external) of 00000011 anywhere on the network.

There are two different scenarios in which you would connect your
Prestige to a LAN: one with a server (server side), and one without a
server (client side).

Novell IPX Configuration 53

Figure 7-1 Prestige Operating in IPX Environment

Prestige on LAN with Server

When your Prestige is being connected to a LAN with an existing

NetWare server station, you will not need to configure it as a seed
router, and hence the network number parameter in the Ethernet
Setup Menu. Rather, your Prestige will learn the network number of
the network it is attached to through the regular RIP broadcasts
sent by the server and add this route to its routing table.

Prestige on LAN without Server

If your Prestige is connected to a LAN without an existing

NetWare server station, then it needs to create a unique external
network number to apply to that frame on the LAN. Your Prestige
must then be configured as a Seed Router, and the network number
can be configured in the Ethernet Setup Menu. The network
number must be unique and not used anywhere else on the entire
network.

54 Novell IPX Configuration

IPX Ethernet Setup

The first step is to set up your Prestige on the LAN. From menu 3,

select option 3 to go to Menu 3.3 - Novell IPX Ethernet Setup as
seen below:

Figure 7-2 Menu 3.3 - Novell IPX Ethernet Setup

1. Seed Router - Determine if your Prestige is to act as a seed
router. This value depends on the existing network. If there is a
NetWare server providing the network number, select No. If there
is no NetWare server providing the network number, select Yes.

2. Frame Type - For every frame type that your Prestige needs to
support, you need to set the corresponding field to Yes. The frame
type(s) selected here must be the same frame type(s) as the server
or client stations on that network. Otherwise, the devices will not be
able to communicate. You can select one or more of these four
frame types:

• 802.2

• 802.3

• Ethernet II

Novell IPX Configuration 55

• SNAP

3. IPX Network # - If you selected your Prestige to act as a seed
router, you need to provide a unique network number to be
associated with the network that it has joined. Keep in mind that
this number must not be used anywhere else on the network.

Once you have completed filling in the Menu 3.3, press ENTER the
save message to save your selections, or press ESC at any time to
cancel your selections.

LAN-to-LAN Application

A typical LAN-to-LAN application is to use your Prestige to call from
a branch office to headquarters such that all of the stations on the
branch office network have access to the server at the headquarters, as
depicted in the following diagram:

For the branch office, you need to configure a Remote Node in order to
dial out to headquarters.

Static Route Setup

If your LAN-to-LAN application has NetWare servers on both sides
of the link, then all NetWare client stations will have access to a server
on their LAN as shown below:

58 Novell IPX Configuration

Figure 7-5 NetWare Servers on Both Sides of the Link

This may present a problem if you desire your client station to access a
server at a remote site. For example, in the above diagram, suppose
that a client station on the network on the left wishes to access the
NetWare server on the right (internal network number = 111).
However, the SAP broadcasts will receive a response from the server
on the left (internal network number = 444). A static route is used to
resolve this problem by providing your Prestige with some static routing
information to access the remote server.

From Menu 12, select one of the four possible IPX Static Routes as
shown below:

8 Bridging Configuration

This chapter shows you how to configure the Bridging options for your
Prestige. Depending on your particular applications, you will need to
configure different menus. We will illustrate the configuration for some
applications in the following sections.

Bridge Ethernet Setup

Bridging is used to forward packets of unsupported protocols whose
destination is not on the local Ethernet to the WAN.

LAN-to-LAN Application

A typical LAN-to-LAN application is to use your Prestige to call from
one office to another office such that stations on one network have
access to stations on the remote side and vice versa. You will need to
configure a Remote Node in order to dial out to another office.

Remote Node Setup

Follow the procedure in Chapter 5 to fill the protocol-independent
parameters in Menu 11, Remote Node Profile. For the protocol­dependent parameters, follow the ensuing instructions:

1. Bridge - Make sure this field is set to Yes.

2. Edit IP/IPX/Bridge - Press the space bar to change it to Yes and
press Enter to go to the network layer options menu as seen below:

9 Filter Configuration

About Filtering

Your Prestige uses filters to decide whether or not to allow passage of a
data packet and/or to make a call over the ISDN line. There are two
types of filters involved: incoming data filters and outgoing data filters.
Data filters screen the data to determine if the packet should be allowed
to pass.

Figure 9-1 Outgoing packet filtering Process

For incoming packets, your Prestige applies data filters only. Packets
are processed depending upon whether a match is made. Your Prestige
allows you to customize the filter sets that you wish to use. The
following sections describe how to configure your Prestige filter sets.

Filter Configuration 67

Prestige’s Filter Structure

You can configure up to twelve filter sets with six rules in each set.
Therefore, your Prestige allows you to customize up to 72 filter rules
(12 x 6).

When implementing these filter sets, you can link up to four of the filter
sets together to screen the data packet. Therefore, with each filter set
having up to six rules, you can have a maximum of 24 rules active for a
single filtering application.

Configuring a Filter Set

In order to distinguish between the 12 filter sets, each filter set should
have a name or some comments. You can edit these comments in the
following way.

1. From the Main Menu, select option 21. Filter Set Configuration.
This will bring you to Menu 21 - Filter Set Configuration.

2. From this menu, you can choose from among the twelve filter sets.
Select the filter set you wish to configure (1-12).

This will bring you to the Edit Comments field. Whatever the comments
are for that filter set will be displayed in this field. You can edit the
comments you wish to use to identify that filter set.

Once you have completed filling in the Edit Comments field, press
ENTER at the message: Press ENTER to Confirm ... to confirm your
selections, or press ESC at any time to cancel your selections. The new
information will now be displayed in the read-only section of Menu 21 ­Filter Set Configuration as shown below:

10 SNMP

About SNMP

The Simple Network Management Protocol (SNMP) is a protocol
governing network management and the monitoring of network devices
and their functions. The Prestige 128L supports the utilization of SNMP
to regulate the communication that occurs between the manager station
and the agent stations in a network. Basically, your Prestige, when
connected to the LAN, acts as an agent station. In this way, the
manager station on your LAN can monitor your Prestige as it would
another station on the network. Keep in mind that SNMP is only
available if TCP/IP is configured.

Configuring Your Prestige For SNMP Support

The following steps describe a simple setup procedure for configuring
SNMP management.

configuration. The parameters you will have to fill in will be
indicated in bold type.

3. Get Community - From this field, you can determine what the Get
Community is for your Prestige. The value entered into this field will
be used to authenticate the community field for the incoming Get­and GetNext- requests from the management station. The default is
public.

4. Set Community - In this field, enter the Set Community for your
Prestige. The value entered in this field will be used to authenticate
the community field for the incoming Set- requests from the
management station. The default is public.

5. Trusted Host - Enter the IP address of the trusted host SNMP
management station. If this field is configured, then your Prestige will
only respond to SNMP messages coming from this address. If you

11 System Security

The Prestige 128L incorporates a number of security measures to
prevent unauthorized access to your network. For example, your
Prestige supports both PAP (Password Authentication Protocol) and
CHAP (Challenge Handshake Authentication Protocol) in authenticating
a Remote Node.

In addition, your Prestige also implements a user password to get into
the SMT screen. You will have three attempts to enter the correct
system password. If all three attempts fail, the SMT will log out. In
addition, your Prestige will only support one user in the SMT at one
time.

12 Telnet Configuration and

Capabilities

About Telnet Configuration

When you first configure your Prestige, it must be done via a computer
connected to the RS-232 port. However, once your Prestige has been
initially configured, you can use telnet to configure the device
remotely as shown below:

Figure 12-1 Telnet Configuration on a TCP/IP Network

In order to configure your Prestige in this way, you need to have
assigned an IP Address to your device and have connected it to your
network. See Chapter 3 for more information on assigning an IP
Address. Once this is configured, any station on the LAN or remote
network that has TCP/IP installed can use telnet remote

Telnet Configuration and Capabilities 85

management. If your Prestige is configured for IPX routing but not IP in
menu 1, telnet will still be available provided you assign your
Prestige an IP address.

Telnet Capabilities

Single Administrator

To prevent confusion and discrepancy on the configuration, your
Prestige will only allow one terminal connection at any time. Your
Prestige also gives priority to the RS-232 connection over telnet. If
you have already connected to your Prestige via telnet, you will be
logged out if another user is connecting to your Prestige via the RS-232
cable. Only after the other administrator has been disconnected will you
be able to telnet to your Prestige again.

System Timeout

When you are connected to your Prestige via telnet, there is a
system timeout of 5 minutes (300 seconds). If you are not configuring
the device and leave it inactive for this timeout period, then your
Prestige will be disconnected automatically.

86 Telnet Configuration and Capabilities

13 System Maintenance

The Prestige 128L provides a full range of diagnostic tools to help you
monitor and maintain your system. Some of these tools provide updates
on system status, ISDN B channel status, log and trace capabilities and
upgrades to system software.

System Status

System Status can be used to monitor your Prestige. Specifically, it will
give you information on the status of your system software version,
