Introduction

Congratulations on your purchase of the ZyXEL Prestige 128 Remote Access Router. The Prestige is the first device to integrate a Router and Bridge into a single package. In a modem-sized box, the Prestige offers inexpensive yet complete telecommunications and internetworking solutions for your home or branch office. The Prestige is ideal for everything from Internet browsing to receiving calls from Remote Dial-in Users to making LAN-to-LAN connections to Remote Nodes.

Distinguishing features of the Prestige 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 Remote Dial-in User support, an Internet Single User Account (Network Address Translation), POTS line support (Plain Old Telephone Service; also called A/B Adapter in Europe), 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 almost any user.

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 Basic Rate Interface (BRI)

Using either a standard S/T or U Interface (128 uses the S/T interface and 128U uses the U interface) the Prestige supports a full range of switch types. The switch type depends on the CO (Central Office) switch your ISDN line is connected to. See Chapter 16 for more information on North American, European, and Asian ISDN firmware and switch types supported by the Prestige.

The two B-channels can be used independently for two destinations. Or they can be bundled for one connection to support bandwidth-on-demand.

Multiple Networking Protocol Support

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

Standar d Phone Ja ck

The Prestige is equipped with two standard phone jacks to connect to telephones, FAX machines, or modems. This allows the ISDN line to be used for voice calls as well as data calls.

2 Introduction

Dial On De mand

The Dial On Demand feature allows the Prestige to automatically place a call to a Remote Node whenever there is traffic coming from any workstation on the LAN to that remote site.

Bandwidth On Dema nd

The Prestige supports bandwidth up to 128Kbps over a single ISDN BRI line. It incorporates PPP/MP (Point-to-Point Protocol/Multilink Protocol) to bundle two B channels over a BRI line. In addition, the Prestige dynamically allocates bandwidth between the two B channels, increasing or decreasing speeds as

needed to allow for greater efficiency in data transfer. It supports BAP (Bandwidth Allocation Protocol) and BACP (Bandwidth Allocation Control Protocol) to manage the number of links in multilink bundle.

Full Network Ma nagement

The Prestige incorporates SNMP (Simple Network Management Protocol) support and menu-driven network management via an RS-232 or Telnet connection. The Prestige is also equipped with a Call Detail Record (CDR) to help analyze and manage your telephone bill.

RADIUS (Remote Authentication Dial In User Service)

The RADIUS feature allows you to use an external, central, Unix based server to support thousands of users.

PPP Securit y

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

DHCP Support (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) allows you to dynamically and automatically assign IP address settings to hosts on your network.

Call Control

The Prestige provides budget management for outgoing calls and maintains a blacklist for unreachable phone numbers in order to save you the expense of unnecessary charges.

Introduction 3

Data Comp r ession

The Prestige incorporates Stac data compression and CCP (Compression Control Protocol).

Networking Compatibility

The Prestige is compatible with remote access products from other companies such as Ascend, Cisco, and 3Com. Furthermore, it supports Microsoft Windows 95 and Windows NT remote access capability.

Applications For Your Prestige

Some applications for the Prestige include:

Internet Access

The Prestige supports the TCP/IP protocol, which is the language used for the Internet. It is also compatible with access servers manufactured by major vendors such as Cisco and Ascend.

Internet Single User Account (SUA)

4 Introduction

For a small office environment, the Prestige offers a Single User Internet Account from an ISP (Internet Service Provider). This allows multiple users on the LAN (Local Area Network) to access the Internet concurrently for the cost of a single user.

Single User Account address mapping can also be used for LAN to LAN connection.

M ultiprotocol LAN-to-LAN Connection

The Prestige can dial to or answer calls from another remote access router connected to a different network. The Prestige supports TCP/IP, Novell IPX, and has the capability to bridge any Ethernet protocol.

Telecommuting Server

The Prestige allows Remote Dial-in Users to dial-in and gain access to your LAN. This feature enables users that have workstations with remote access capabilities, e.g., Windows 95, to dial in using an ISDN terminal adapter (TA) to access the network resources without physically being in the office.

What This Manual Covers

This manual is divided into five parts.

1. Part One - Getting Started (Chapters 1-3) - is structured as a step-by-step guide to help you connect, install, and setup your Prestige to operate on your LAN.

2. Part Two - The Internet (Chapter 4) - describes how to configure the Prestige to connect to the Internet.

3. Part Three - Setting Up Advanced Applications (Chapters 5-

10) - describes how to use the Prestige for more advanced applications, such as TCP/IP routing and Bridging.

4. Part Four - Advanced Management (Chapters 11-14) provides information on advanced management features for network managers.

5. Part Five - System Maintenance (Chapters 15-16) - describes maintenance features for checking system status and logging errors.

Regardless of the application, it is important that you follow the steps outlined in Part One (Chapters 1-3) to correctly connect your Prestige to your LAN. You can then refer to other chapters of the manual depending on which applications you wish to use.

10 Before You Begin

Ordering Your ISDN Li ne

If you do not have the ISDN line installed already, we suggest that you order it from your telephone company as soon as possible to avoid the long waits common when ordering a new line. Use the information in this section to place the order (see Chapter 16 for information on provisioning your ISDN line). If you have already installed your ISDN line, you can check the following section to make sure that you can use all the features of your Prestige.

1. Contact your local telephone company’s ISDN Ordering Center.

2. Find out what type of ISDN service is available. Refer to Chapter 16 to find out the provisioning information for the appropriate switch type and ISDN service. For the U.S., the Prestige (both U and S/T Interface) have been approved by Bellcore and have IOC (ISDN Ordering Code) “S” Capability, EZ-ISDN 1.

3. Provide your telephone company with the proper provisioning information.

4. When the telephone company installs your ISDN line, be sure to obtain the following information:

• ISDN switch type.

• ISDN telephone number(s).

• ISDN Service Profile Identifiers (SPID) number(s) (only for

North America).

Collecting General Setup Information

The 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.

Before You Begin 11

• System Name - This is the name given to the 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 IS DN Phone Line Information

After you have successfully installed the ISDN phone line or if you already have one installed, you need to use the ISDN line information to complete the worksheet and configure your Prestige. Your telephone company can give you the following information to configure the Prestige:

• Switch Type - This is the type of switch used by your

telephone company. Check with your telephone company and choose the appropriate option on the worksheet. For North

America, select your ISDN switch type. For DSS1 and 1TR6, verify this field to make sure that you have the proper firmware loaded.

• B Channel Usage - Determine which connection is appropriate for your B channel and check the corresponding option on the worksheet.

If your Prestige is the only device using the ISDN line, then

configure B Channel Usage to Switch/Switch so that your device will use both B channels to communicate. If your Prestige is sharing the ISDN line with other devices, then configure B Channel Usage to Switch/Unused.

• Telephone Number(s) - Record on the worksheet the telephone number(s) given to you by your ISDN provider. Some switch types only have one telephone number. These phone numbers should be in a standard digit format (for example, 5551212). Note that these fields will only accept digits, so - and spaces will not be accepted.

• Analog Call - Check the appropriate Analog Call option on the worksheet for each telephone number. This information is later used to configure the Prestige in routing an incoming analog call. Set to Phone1 or Phone2 if you wish to route the incoming analog call for this telephone number to PHONE port number 1 or 2.

• SPID Number(s) - (For North America only) The SPID (Service Profile Identifier) is a number used by a central office switch for identification purposes. With the switch information, see the previous table for the number of SPIDs you must enter.

You have now collected all of the necessary information about your ISDN phone line. Make sure that these values are entered into

Before You Begin 13

your worksheet before you continue to the next section. For DSS1 and 1TR6 ISDN, refer to Chapter 3.

Collecting Ether net Setup Informa ti on

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 on the Prestige. 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.

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.

14 Before You Begin

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 as calculated by the Prestige.

IP Subnet Mask Number of Host IDs Number of Bits

255.255.255.0 254 24

255.255.255.128 126 25

Connecting a Telephone/Fax to y our Pre stige

If you wish, you can connect a regular telephone, fax machine, or a modem to your Prestige to be used for analog calls just like a

normal phone line. It should be noted that this is optional and is not required for you to run other applications using your Prestige.

Plug one end of the telephone cord from a phone, fax, or modem into the socket on the rear panel of the Prestige labeled PHONE 1 or PHONE 2.

In order to receive incoming calls using a device connected to PHONE ports, you need to enter Phone1 or Phone2 in the Analog

Call field under the desired telephone number (e.g., 1

phone #) in

SMT Menu 2 - ISDN Setup. See Collecting ISDN Phone Line Information in Chapter 2 for more details.

Connecting an Ethernet Cabl e to your Prestige

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

• UTP

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:

• AUI

The AUI port (the connec tor with 15 pins) is used to connect the Prestige to a 10Base5 (thicknet) network.

Installation 23

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 a Power Adapter to your Prestige

Plug a 16VAC 1200mA 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.

subaddress. Or it will be answered as A/B Adapter 2 call when there is a match for the A/B Adapter 2 subaddress. If A/B Adapter 1 or 2 subaddress is specified, then the analog call will not be answered. This option is only available for DSS1.

• Don’t care - all numbers accepted - All digital calls,

including global calls (without CDPN and CDSA in the call setup), to any Called Party Number will be answered. All analog calls will be routed to A/B Adapter 1, A/B Adapter 2, or not answered. This depends on the setting of Analog Call Routing. All global analog calls will either accept or not answer them depending on the setting of Global Analog Call.

9. Analog Call Routing - All analog calls will be routed to A/B

Adapter 1 if the setting is A/B Adapter 1. Or they will be routed to the A/B Adapter 2 if the setting is A/B Adapter 2. Or they will not be answered if the setting is Ignore.

10. Global Analog Call - All global analog calls will be answered

and routed to the A/B Adapter 1 or A/B Adapter 2 (the setting in the filed of Analog call routing) if the setting is Accept. Or they will not be answered if the setting is Ignore.

34 Installation

When you are finished, press ENTER at the message: Press ENTER to Confirm ... to save your selections, or press ESC to cancel. When you press ENTER, the Prestige will use the information that you entered to initialize the ISDN link to the telephone company switch. It should be noted that whenever the switch type is changed, the ISDN initialization will take slightly longer. In addition, if you are using the U-interface, the system will also take slightly longer to initialize.

At this point, the Prestige will ask if you wish to test to check if your ISDN line has been successfully connected to your Prestige. If you select Yes, the Prestige will perform a loop-back test to check

the ISDN line. If the loop-back test fails, note the error message that you receive and take the appropriate troubleshooting action.

Ethernet Setup

Menu 3 is used to enter Ethernet related information. Depending on the protocols (TCP/IP or IPX) on your LAN, you will need to configure each protocol separately.

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 10, 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.

36 Installation

Figure 3-12 Menu 3.2 - TCP/IP Ethernet Setup

DHCP

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

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 the Prestige itself. This address will also serve as the default gateway for DHCP clients.

Size of Client IP Pool

- Gives the size of the block of

addresses reserved for DHCP address assignment. The Prestige

Installation 37

itself 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 the 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. 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 subnet mask calculated by the Prestige.

7. RIP Direction - This parameter determines how the Prestige

handles RIP (Routing Information Protocol). If set to Both (default), the 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, the Prestige will not broadcast its routing table on the LAN, if set to Out Only, the Prestige will broadcast its routing table but ignores any RIP broadcast packets that it receives. If set to None, the Prestige will not participate in any RIP exchange with other routers.

38 Installation

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

and let RIP propagate the routing information automatically.

When you are finished, press ENTER at the message: Press ENTER to Confirm... to save your selections, or press ESC at any time to cancel them.

• Telephone number(s) of your ISP.

• Login name.

• Password for ISP authentication

For your Workstation:

• Domain Name Server (DNS)

Figure 4-1 Internet Access

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.

1127(27(

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.

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 36 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.

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.

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.

42 Configuring for Internet Access

Figure 4-2 Menu 4 - Internet Access Setup

4. Pri(mary) Phone # and Sec(ondary) Phone Number - Both the Primary and the Secondary Phone number refer to the number that the Prestige will dial to connect to the ISP. The Prestige will always call your ISP using the Primary Phone number first. If the Primary Phone number is busy or does not answer, the Prestige will call the Secondary Phone number if available. Once connected, the Prestige will use the BACP (Bandwidth Allocation Control Protocol) to establish the second B-channel if PPP/MP is enabled, and the ISP also supports MP and BACP.

5. My Login Name - Enter the login name given to you by your ISP.

6. My Password - Enter the password associated with the login name above. Note that this login name/password pair is only for the 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.

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

8. Telco Options: Transfer Rate - This field (which only applies to outgoing calls) controls the rate at which the data is transferred between your Prestige and the Internet. The options for this field are:

• 64K - The Prestige will place 64Kbps (bits per second)

digital data calls.

• 56K - (For the North America only) The Prestige will place

56Kbps digital data calls.

• DOVBS - (For the North America only) The Prestige will

place 56Kbps Data Over Voice Bearer Service (DOVBS)

Configuring for Internet Access 43

call. Some phone companies in North America charge less if calls are made using DOVBS.

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

10. At this point, the SMT 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.

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).

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

44 Configuring for Internet Access

defined, all incoming inquiries will be filtered out by the Prestige even if you do have a server on your network. This can prevent intruders from probing your system.

The 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,

(NAT)

The IP Network Address Translator

In summary:

1. 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.

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

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

4. 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 the 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.

Configuring Backup ISP Accounts

Sometimes it may be desirable to configure more than one ISP account for backup purposes. The Single User Account feature can be enabled for all of these accounts, making it convenient to switch Internet Service Providers in the event of a failure.

To configure a backup ISP,

1. Configure your primary ISP using Menu 4, as described earlier in this chapter.

2. Enter Menu 11, then select the number of an unused remote node.

3. In Menu 11.1, choose a name for your backup ISP account, set the Active field to No, and enter your outgoing login name, password, and phone number(s). The Remote IP Address field should be set to 1.1.1.1.

4. In Menu 11.3, set the remote node’s subnet mask to 0.0.0.0, and set RIP to None.

5. Save the new configuration.

Once you have done this, if you need to change from your primary ISP to a backup ISP follow the steps below:

1. Enter Menu 11 and select your Primary ISP.

2. In Menu 11.1, set the Active field to No.

3. Enter Menu 11 again and select your backup ISP.

4. In Menu 11.1, set the Active field to Yes.

Remote Node Configuration

A Remote Node represents both a remote gateway and the internet behind it, across an ISDN connection. A Remote Node is required for placing calls to or answering calls from a remote network. Note that when you use Menu 4 to configure the Internet, the Prestige will automatically add a Remote Node for you. Once a Remote Node is configured properly, traffic to the remote LAN will trigger the Prestige to make a call automatically (i.e., Dial On Demand). Similarly, calls from the remote LAN will be answered automatically and security will be checked.

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 7. For IPX, see Chapter 8. For bridging, see Chapter 9.

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.

Active -

Press the space bar to toggle between Yes and No.

When a Remote Node is deactivated, it has no effect on the

Remote Node Configuration 51

operation of the 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. Call Direction - If this parameter is set to Both, the Prestige

can both place and receive calls to/from this Remote Node. If set to Incoming, the Prestige will not place a call to this Remote Node. If set to Outgoing, the Prestige will drop any call from this Remote Node.

Several other fields in this menu depend on this parameter. For

example, in order to enable Call Back, the Call Direction must be Both.

4. Incoming: Rem Node Login Name - Enter the login name that

this Remote Node will use when it calls into the Prestige. The login name in this field combined with the Rem Node Password will be used to authenticate the incoming calls from this node.

5. Incoming: Rem Node Password - Enter the password used

when this Remote Node calls into the Prestige.

6. Incoming: Rem CLID - This field is active only if Call

Direction is either Both or Incoming. Otherwise, an N/A appears in the field. This is the Calling Line ID (the telephone number of the calling party) of this Remote Node. If you enable the CLID Authen field in Menu 13 - Default Dial In, the Prestige will check this number against the CLID in the incoming call. If they do not match and the CLID Authen is Required, then the Prestige will reject the call.

7. Incoming: Call Back - This field will be valid only if Call

Direction is Both. Otherwise, an N/A appears in the field. This field determines whether or not you wish the Prestige to call back after receiving a call from this Remote Node. If this option is enabled, the Prestige will disconnect the initial call

52 Remote Node Configuration

from this node and call it back at the Outgoing Primary Phone Number (see below).

8. Outgoing: My Login Name - This is a required field if Call

Direction is either Both or Out. Enter the login name for the Prestige when it calls this Remote Node.

9. Outgoing: My Password - This is a required field if Call

Direction is either Both or Out. Enter the password for the Prestige when it calls this Remote Node.

10. Outgoing: Authen - This field sets the authentication protocol

used for outgoing calls.

The 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:

• CHAP/PAP - 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.

11. Outgoing: Pri(mary) Phone Sec(ondary) Phone Number -

Both the Primary Phone number and the Secondary Phone number refer to the number that the Prestige will dial to connect to the Remote Node. The Prestige will always call the

Remote Node Configuration 53

Remote Node using the Primary Phone number first. If the Primary Phone number is busy or does not answer, the Prestige will call the Secondary Phone number if available. Once connected, the Prestige will use the BACP (Bandwidth Allocation Control Protocol) to establish the second B-channel if Multilink PPP is enabled, and the Remote Node supports MP and BACP.

Some areas require dialing # before the phone number for local

calls. A # symbol may be included at the beginning of the Primary Phone number or Secondary Phone number.

12. Route - This fields determines the protocols that the Prestige

will route. The choices for this field are determined by the features enabled on your Prestige.

13. Bridge - Bridging is used for protocols that are not supported

or not turned on in the previous Route field by the Prestige, e.g., SNA. When bridging is enabled, the 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.

14. 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.

15. IP Addr - This is a required field if Route is set to IP. Enter the

IP address of this Remote Node.

16. 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

54 Remote Node Configuration

Options. For more information on filling out this screen, refer to the chapter pertaining to your specific protocol.

17. Telco Options: Transfer Rate - This field (which only applies

to outgoing calls) controls the rate at which the data is transferred between your Prestige and the Remote Node. The options for this field are:

• 64K - The Prestige will place 64Kbps (bits per second)

digital data calls.

• 56K - (For North America only) The Prestige will place

56Kbps digital data calls.

• DOVBS - (For North America only) The Prestige will place

56Kbps Data Over Voice Bearer Service (DOVBS) call. Some phone companies in North America charge less if calls are made with DOVBS option.

18. Telco Options: Allocated Budget (min) - This field will set a

budget outgoing call time for the Remote Node. The default for this field is 0 for no budget control.

19. Telco Options: Period (hr) - This field will set the time

interval to reset the above outgoing call budget control.

20. Session Option: Input Filter Sets, Output Filter Sets and Call 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 and the 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 10. The default is blank, i.e., no filters defined.

21. Session Option: Idle Timeout (sec) - This value specifies the number of idle seconds that elapses before the Remote Node is automatically disconnected. Idle seconds is the period of time

Remote Node Configuration 55

where no data is passed between the Remote Node and your Prestige. Administrative packets such as RIP are not counted as data. The default is 300 seconds (5 minutes).

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.

Bandwidth on Demand

The Bandwidth on Demand (BOD) feature allows you to bundle both B channels in one connection. The second channel is added and subtracted dynamically according to traffic demand. The Prestige uses the Bandwidth Allocation Control Protocol (BACP) and the Multilink Protocol (MP) to implement bandwidth on demand.

The configuration of bandwidth on demand focuses on the Base Transmission Rate (BTR) and the Maximum Transmission Rate (MTR). The relationship between BTR and MTR are shown below:

BTR & MTR Setting No. of

BTR = 64, MTR = 64 1 1 Off BTR = 64, MTR = 128 1 2 On BTR = 128, MTR = 128 2 2 Off

When bandwidth on demand is enabled, a second channel will be brought up if traffic on the initial channel is higher than the high Target Utility number for longer than the specified Add Persist value. Similarly, the second channel will be dropped if the traffic level falls below the low Target Utility number for longer than the Subtract Persist value.

The Target Utility specifies the line utilization range at which you want the Prestige to add or subtract bandwidth. The range is 30 to

56 Remote Node Configuration

channel(s) used

Max No. of channel(s) used

Bandwidth on demand

64 kbps (kilobits per second). The parameters are separated by a -. For example, 30-60 means the add threshold is 60 kbps and subtract threshold is 30 kbps. The Prestige will perform bandwidth on demand only if it initiates the call. Addition and subtraction are based on the value set in the BOD Calculation field. If this field is set to Transmit or Receive, then traffic in either direction will be calculated to determine if a link should be added or dropped. Transmit will only use outgoing traffic to make this determination, and Receive will only use incoming traffic to make this determination.

If, after making the call to bring up a second channel, the second channel does not succeed in joining the Multilink Protocol bundle (because the remote device does not recognize the second call as coming from the same device), the Prestige will hang up the second channel and continue with the first channel alone.

Dial-In Configuration

You can configure the Prestige to receive calls from Remote Dialin Users (e.g. telecommuters) and Remote Nodes. There are several differences between Remote Dial-in Users and Remote Nodes:

1. The Prestige can make calls to or answer calls from the Remote Node. However, the Prestige will only answer calls from Remote Dial-in Users.

2. Each Remote Node can have its own set of parameters such as Bandwidth On Demand, Protocol, Security, etc.; while all Remote Dial-in Users share one common set, as defined in the Default Dial In Setup (Menu 13).

3. Generally, Remote Dial-in Users are individual users who dial in to the Prestige directly from their workstations, while Remote Nodes represent networks and are used for LAN-toLAN connections.

This chapter discusses how to setup Default Dial-in parameters for both Remote Node and Remote Dial-in Users. The following sections give two examples of how the Prestige can be configured as a dial-in server for either or both.

By default, the Prestige allows information for up to eight users to be kept. If more than eight remote dial-in users can access the Prestige, you can use a separate RADIUS server to provide remote authentication services. For details on using a separate RADIUS server, see the Using RADIUS Authentication section in Chapter

12.

60 Dial-In Configuration

Telecommuting

Telecommuting enables people to work at remote sites and yet

still have access to the resources in the business office. Typically, a telecommuter will uses a client workstation with TCP/IP or IPX and dial-out capabilities, e.g., a Windows 95 PC or a Macintosh and an ISDN Terminal Adapter (TA). For telecommuters to call in to your LAN, you need to configure a Dial-In User Profile for each telecommuter. Additionally, you need to configure the Default Dial-In Setup to set the operational parameters for all dial-in users. You can configure up to eight Remote Dial-in Users for the Prestige.

An example of Remote Dial-in User application,

telecommuting, is shown below:

Figure 6-1 Example of Remote User: Telecommuter

Dial-In Server Application

The Prestige can also be used as a dial-in server. This

application allows the Prestige to provide services for workstations on a remote network. For the Prestige to be set up as a dial-in server, you need to configure the Default Dial-In Setup to set the operational parameters for incoming call. Additionally, you will have to create a Remote Node for the

Dial-In Configuration 61

router on the remote network (see Chapter 5). An example of the Prestige being used as a dial-in server is shown below:

Figure 6-2 Example of a Dial-In Server Application

Default Dial-In Setup

This section covers the default dial-in parameters. The

parameters in Menu 13 affect incoming calls from all Remote Dial-in Users and Remote Nodes before authentication is completed. Once authentication is completed, and if it matches a Remote Node, the Prestige will use parameters from that particular Remote Node.

62 Dial-In Configuration

Figure 6-3 Menu 13 - Default Dial-in Setup

From the Main Menu, enter 13 to go to Menu 13 - Default Dial-in Setup. This section will describe how to configure the protocolindependent fields in this menu. For the protocol-dependent fields, refer to the appropriate chapters.

Telco Options: CLID Authen.

- This field sets the CLID authentication parameter for all incoming calls. There are three options for this field:

•

- No CLID is required.

None Required Preferred

- Must provide CLID, or call is disconnected.

- If the CLID is available then CLID will be used to do authentication. If the CLID is not available the call will continue.

PPP Options: Recv. Authen. -

This field sets the authentication protocol used for incoming calls. User names and passwords are configured in the next section (Remote users/Dial-in Users Setup). Options for this field are:

•

CHAP/PAP

used if CHAP is not available.

•

CHAP

- Prestige will try CHAP first, but PAP will be

- Use CHAP only.

Dial-In Configuration 63

• None - No authentication required.

3. PPP Options: Mutual Authen. - Some vendors, e.g. Cisco,

implement a type of mutual authentication. That is, the node that initiates the call will request a user name and password from the far end that they are dialing to. If the Remote Node that is dialing in implements this type of authentication, set this field to Yes.

4. PAP Login - This field will only be enabled if the Mutual

Authen. field is set to Yes. Enter in the login name to be used to respond to the far end’s PAP authentication request. This field does not apply to CHAP authentication.

5. PAP Password - This field will only be enabled if the Mutual

Authen. field is set to Yes. Enter in the PAP password to be used to respond to the far end’s authentication request. This field does not apply to CHAP authentication.

6. Multiple Link Options: Max Trans Rate - Enter the

maximum data transfer rate between your Prestige and the Remote Dial-in User. The unit is in bits per second. There are two options for this field:

• 64 - At most, one B channel will be used.

• 128 - A maximum of two channels can be used.

When the Prestige calls back to the Remote Dial-in User the

maximum data transfer rate is always 64.

7. Callback Budget Management: Allocated Budget (min) -

This field will set a budget callback time for all the Remote Dial-in Users. The default for this field is 0 for no budget control.

8. Callback Budget Management: Period (hr) - This field will

set the time interval to reset the above callback budget control.

9. Dial-In IP Address Supplied By: Dial-in User - If set to Yes,

it tells the Prestige to allow a remote host to specify its own IP

64 Dial-In Configuration

address. This is to prevent the remote host from using an invalid IP address and potentially disrupting the whole network. If set to No, the remote host must use the IP address assigned by the Prestige from the IP pool, configured below. The default is Yes.

10. Dial-In IP Address Supplied By: IP Pool - This field tells the

Prestige to provide the remote host with an IP address from the pool. This field is required if Dial-In IP Address Supplied By: Dial-in User is set to No. You can configure this field even if Dial-in User is set to Yes, in which case the Prestige will accept the IP address if the remote peer specifies one; otherwise, an IP address is assigned from the pool. The default is No.

11. IP Pool: IP Start Addr - This field is active only if you

selected Yes in the Dial-In IP Address Supplied By: IP Pool field. The IP pool contains contiguous IP addresses and this field specifies the first one in the pool.

12. IP Count (1,2) - In this field, enter the number (1 or 2) of the

addresses in the IP Pool. For example, if the starting address is

192.168.135.5 and the count is 2, then the pool will have

192.68.135.5 and 192.68.135.6

13. Dial-In IPX Net. Num. Supplied By: IPX Pool - This field

tells the Prestige to provide the remote host with an IPX network number from the pool. Otherwise, the Prestige will generate a random IPX network number. The default is No.

14. IPX Start Net. Num. - This field is active only if you selected

Yes in the Dial-In IPX Net. Num. Supplied By: IPX Pool field. The IPX pool contains contiguous IPX network numbers and this field specifies the first one in the pool.

15. IPX Count (1,16) - In this field, enter the number (1 - 16) of

network numbers in the IPX Pool. For example, if the starting number is 12345678, and the count is 2, then the pool will have 12345678 and 12345679.

Dial-In Configuration 65

16. Session Options: Input Filter Sets and Session Options: Output Filter Sets - In these fields, you need to select the

filter set(s) to filter the incoming and outgoing traffic between your Prestige and the Remote Dial-in User. Keep in mind that these filter set(s) will only apply to all Remote Dial-in Users but not the Remote Nodes.

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 10 on Filter Configuration. The default is blank, i.e., no filters.

17. Session Options: Idle Timeout - This value is the number of idle seconds that elapses before the dial-in user is automatically disconnected. Idle Timeout is the period of time when there is no data traffic between the dial-in user or Remote Node and the Prestige. This field will only be used if the Recv. Authen is set to None and the call is not mapped to any Remote Node or Remote Dial-in User or the Prestige calls back to the Remote Dial-in User.

Once you have completed filling in Menu 13 - Default Dial-in Setup, press ENTER at the message: Press ENTER to Confirm ... to save your selections, or press ESC at any time to cancel your selections.

Dial-In Users Setup

The following steps describe the setup procedure for adding a Remote Dial-in User. From the Main Menu, enter 14 to go to 14. Dial-in User Setup is shown below:

User Name

- This is a required field. This will be used as the login name for authentication. Choose a descriptive word for login, e.g., peterhousel.

Active -

You can disallow dial-in access to this user by setting this field to Inactive. When set to inactive, the user record is still kept in the database for later activation. Deactivated users

Dial-In Configuration 67

are displayed with a - (minus sign) at the beginning of the name in Menu 14.

3. Password - Enter the password for the Remote Dial-in User.

4. Callback - This field determines if the Prestige will allow call

back to the Remote Dial-in User upon dial-in. If this option is enabled, the Prestige will be able to call back to the Remote Dial-in User if they request it. In such a case, the Prestige will disconnect the initial call from this user and dial back to the specified call back number (see below). The default is no callback.

5. Callback Phone # - If Callback is Yes, then this is a required

field. Otherwise, an N/A will appear in the field. Enter the telephone number to which the Prestige will call back.

6. Callback Override - If Callback is No, an N/A will appear in

the field. The callback override allows the Remote Dial-in User to specify the call back telephone number on call-by-call basis. This is useful for when the Prestige returns a call back to a mobile user at different numbers, e.g., a sales rep in a hotel. Note that the default is No, i.e., the Prestige always calls back to the fixed callback number.

7. Rem CLID - If you have enabled the CLID Authen field in

Menu 13, then you need to specify the telephone number from which this Remote Dial-in User calls. The Prestige will check this number against the CLID in the incoming call. If they do not match and the CLID Authen is Required, then the Prestige will reject the call.

8. Idle Time-out - Enter the idle time (in seconds). This time-out

determines how long the dial-in user can be idle before the Prestige disconnects the call. Idle time is defined as the period of time where there is no data traffic between the dial-in user and the Prestige. The default is 300 seconds (5 minutes).
