2. Introduction

This chapter introduces Router technology, features, and applications. Installation instructions begin in Chapter 3.

If you are upgrading a previous version of the Router, make sure you read Appendix C in the Reference

Manual.

The Routers are remote access servers that route TCP/IP and IPX (NetWare®) traffic. Routers connect remote local area networks (LANs) and clients to Ethernet-based LANs, using standard V.34 modems, or synchronous lines (leased or switched). Personal computers can access Router servers using the Async Client software. Macintosh

and other non-PC clients can dial into a Router using the standard point-to

point protocol (PPP).

Three models are available:

Table 2-1. Router Models.

Model WAN Capabilities

Async Router AR-P (LRA001A-R2) 1 V.34 modem

Async Router AR-5 (LRA005A-R2) 5 V.34 modems

Sync Router (LRS002A-R2) 1 sync interface, 1 V.34 modem

2.1 Applications

All Router models provide autosensing Ethernet interfaces (10BASE-T, AUI), and support multiple protocols for both LAN-to-LAN and user-to-LAN (remote-client access) routing. All Routers have an internal V.34 modem (the AR-5 model has five internal modems).

2.1.1 T

RANSPARENT LAN-TO-LAN ROUTING

For transparent routing between separate Ethernet-based LANs, pair two Routers together or use compatible devices. Use any Router model to provide inexpensive networking solutions for remote of fices. For maximum throughput, use the Sync Router for synchronous connections.

2.1.2 T

RANSPARENT REMOTE CLIENT ACCESS

For remote client access, the Router acts as a remote node server, allowing IPX- and TCP/lP-based PCs and laptop computers to become remote nodes on an Ethernet-based network attached to the Router. Remote client workstations can then dial into the Router to access services on the LAN as if they were local nodes. The Router supports transparent access for a maximum of 100 remote clients, and accepts calls from any client on any dial-up modem line configured for client access.

2.1.3 R

EMOTE CLIENTS AND LANSWITHDUAL-STACK FUNCTIONALITY

Router supports dual-stack functionality in both remote LAN-to-LAN and remote client operations. IP and IPX protocols are supported, so that any DOS or Windows®based PC, Macintosh, or UNIX

workstation can access the Router. The Router uses the standard PPP protocol, which allows third-party client applications to access the Router.

ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

2.2 Shared Router Features

All Router models share the following features:

• Included or optional internal 28.8K modems (V.34)

• IP and IPX routing, separately or simultaneously

• PPP, IPCP, IPXCP, PAP, and CHAP protocols

• Remote client access (supports a maximum of 100 clients):

- time filter

- connect quota

- idle timeout

- security callback

• Extensive IP and IPX packet filtering on all interfaces

• Simple configuration for all supported interfaces: Ethernet, modem, and synchronous interfaces

• Superior handling of IP RIP updates

• Extensive dial-up monitoring capabilities

• Automatic recognition of network topology and services

• Support for primary and secondary phone numbers (used for each modem interface)

2.2.1 E

ASY TO INSTALL AND CONFIGURE

Routers are shipped ready for installation and configuration. Installation is described in Chapters 3, 4, and 5. You configure the Router with a dialogue that prompts you to enter the desired LAN, WAN and client parameters. To configure the Router, you can use either a PC with a terminal emulator like Windows Terminal or a serial terminal connected to the Router’s console port, or use a host computer with telnet on the local Ethernet (TCP/IP), or use a host PC with RouterVu (included with the Router) on the local Ethernet (IPX).

2.2.2 R

EDUCES OPERATING COSTS

The Router supports idle timeouts and time quotas to reduce operating costs. Finally, the Router can restrict a client’s access to the network, using the concept of a configurable client access shift. A client account can be restricted to client access during shift hours (IN), after hours (OUT), or 24 hours of the day.

2.2.3 D

IAL SUPPRESSION

Router link optimization (RLO) recognizes and minimizes unnecessary traffic. RLO has IPX and SPX filters to prevent dialing for and forwarding of, network traffic that doesn’t originate from end-users. Although it is enabled by default, RLO can be manually enabled and disabled. See Appendix B, Line use.

Standard IP and IPX filters can also be used to suppress unnecessary dialing activities.

ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

2.2.4 PREVENTS UNAUTHORIZED NETWORK ACCESS

The Router offers comprehensive security mechanisms to prevent unauthorized network access. The Router security operates at several levels:

• PPP link-level security (over the WAN link)

• IP, IPX, and SPX packet filtering

• passwords for ftp and telnet servers (IP)

• console login and password

• passwords for RouterVu logins (IPX)

• security callback to remote users (clients)

• client logins and passwords

2.2.5 I

NTEROPERABLE WITH RADIUS AND SECURID SERVERS

The Router interoperates with RADIUS and SecurID authentication servers. RADIUS allows administrators to centrally store and manage names and passwords for IP sites with many dial-in routers and remote clients. SecurID requires remote clients to physically possess a SecurID metal card, in order to gain network access.

NOTE

SecurID and RADIUS technologies cannot be used at the same time on a Router.

2.2.6 PPP LINK-LEVEL SECURITY

For PPP link-level security, the Router supports the Challenge Handshake Authentication Protocol (CHAP) and the Password Authentication Protocol (PAP). Both PAP and CHAP require password and node names for linking to prevent unauthorized users from gaining access through the Router. We strongly recommend using CHAP to provide security.

Along with PAP and CHAP, a new security CHAP (SCHAP) for Router clients supports security callback. A modem configured for client access attempts to negotiate CHAP, PAP, then SCHAP authentication.

2.2.7 IP

AND IPX PACKET FILTERING

The Router’s extensive IP and IPX filtering allows specific hosts, networks, and services—mail, terminal, print, and file services—to be excluded from, or allowed access to, your network.

2.2.8 PREDEFINED IP PACKET FILTERS

If you will be using the Router to provide Internet access to your users, you have the option of installing a list of IP filters that are commonly used to protect networks from unauthorized access by Internet users. Refer to Appendix B.

2.2.9 P

REDEFINED IPX PACKET FILTERS

You also have the option of installing a list of IPX filters that are commonly used to suppress dialing caused by unnecessary network traffic such as:

• Pings from NetWare servers

• SPX idle traffic

• NetBIOS name broadcasts between servers

ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

• Any other IPX broadcasts.

Also refer to Appendix B.

2.2.10 P

ASSWORDS FOR FTP AND TELNET SERVERS

Passwords must be used to log in and transfer files to prevent unauthorized access.

2.2.11 C

ONSOLE LOGIN

When a serial terminal (console) is in use, a login and password are required.

2.2.12 P

ASSWORDS FOR ROUTERVU LOGINS (IPX)

Passwords must be used to log in to a Router with RouterVu.

2.2.13 S

ECURITY CALLBACK TO REMOTE USERS

A security callback feature can be enabled for any Async Router client. The client must be located at a specific phone number to access the Router. Security callback only works with Async Router clients.

Once a physical link is established, and before packet routing commences, the calling workstation presents a user name and password for authenticity. If the password is authentic, Router directs the client to end the phone session and enter into auto-answer mode, anticipating a response from the Router. Once the Router responds to the client, the process to determine authenticity ends. If a client attempts to establish a connection to a modem designated as a LAN-to-LAN line, the connection fails.

2.2.14 C

LIENT PASSWORDS

The Router maintains a database supporting a maximum of 100 remote clients. Each record in this client database is associated with a single client. Each record of the database stores a client’s name, password, connect quota (length of time each day a client is allowed to access the Router), idle timeout (length of time network inactivity is allowed to keep up the connection), security callback phone number, and shift access choice (access based on time of day).

2.2.15 C

OMPRESSION FOR SYNCHRONOUS INTERFACES

The Router provides compression for synchronous interfaces on the Sync Router, in both TCP/IP and IPX networks. For the sync0 interface, compression is enabled by default, but can be disabled using the ppp command. The Router implements compression using Stacker™ algorithms from Stat Electronics.

A synchronous PPP link can have two different compression methods on the same link, one in each direction. “No compression” counts as a compression method. Although theoretically multiple compression methods can be active across each direction of a PPP link, the Router supports only one method of compression per direction on a link.

Example:

For example, suppose your Router is linked to a remote router. There are two connections on the same links: one from your Router to the remote router, and one from the remote router to your Router.

When the Router establishes a link, it negotiates with the Router at the other end to select what type of compression will be used. During the negotiation, the Router will indicate a preference for the Stacker compression method.

ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

2.3 Async Router AR-5 (LRA005A-R2) Features

The Async Router AR-5 has five internal V.34 modems. It connects LANs and clients at up to 28.Kbps over normal telephone lines.

2.4 Sync Router (LRS002A-R2) Features

The Sync Router works the same way as the Async Routers, except that it connects LANs over a variety of synchronous serial line types:

• Leased digital data service at 56 Kbps (North America) or 64 Kbps (Europe), i.e., a fixed line from one location to another, using an external Channel Service Unit/Data Service Unit (CSU/DSU).

• Switched 56 Kbps service, available in North America from either the local or the long-distance telephone companies, using an external CSU/DSU with dialing capability.

• ISDN basic rate service at 56 Kbps (referred to as voice, or 56 Kbps data), 64 Kbps (referred to as transparent data), or 128 Kbps (with bonding), using an external synchronous terminal adapter. If you want to use ISDN circuits, we recommend using the ISDN models that will be released in the future.

• Switched circuits, using synchronous V.34 modems (such as ZyXEL U1496+) over normal telephone lines. This type of circuit is not generally useful, since the standard compressing asynchronous modems used with the Router generally provide superior performance.

2.4.1 A

UTOMATIC FALLBACK

If a leased synchronous line fails, the Router’s built-in modem automatically supports fallback to the modem, for both IP and IPX routing.

2.4.2 SYNCHRONOUS ROUTER INTERFACE

The Sync Router operates as an interface between synchronous routers from:

• Cisco

• Novell (MPR = Multi-Protocol Router)

• XYPLEX

• Wellfleet

Supported CSU/DSUs include (but are not limited to):

For digital data service:

• Our CSU/DSU MS (part number MT132A-R2)

• LarsE M5600 Multi-rate CSU A CSU/DSU with dual interface mode (V.35/EIA-232).

• Motorola/UDS DSS/MR (the Router works with the V.35 version only, of this CSU/DSU).

• Motorola/UDS DSS/V.32 A CSU/DSU which can use a dial-up V.32 connection as backup to a leased 56-Kbps line without using the modem port of the Router.

For switched-56 data service:

• Our CSU/DSU MS/DBU (SW56) (part number MT134A-R2): A CSU/DSU for 4-wire switched-56 service with AT-command or V.25 bis dialing support to RS-232 or V.35 DTE. This CSU/DSU can also be used for digital data service (DDS).

ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

• Motorola/UDS SW56 II A CSU/DSU that can be used for DTR dialing on a Switched-56 network, or used for DDS.

For ISDN service:

• Black Box/EAZY part number IS280A.

• Adtran ISU 128: An ISDN/BRT TA (terminal adapter) that can create one 112 Kbps channel out of the two B channels on an ISDN BRI line.

• Motorola/UDS TA-220 and TA-220K: An ISDN/BRI TA that allows two different terminals to be active on different calls simultaneously. It also allows the two channels to be “bonded” into one 112 Kbps channel.

The Sync Router performs identically to the Async Router AR-P, unless specifically noted inn this document.

2.5 Async Client Kit

Each Async Router AR-5 is shipped with Async Client kits (also called RemoteOffice), and SmartRoute™ software that supports up to 100 clients. Each Async Client kit includes:

• Remote Office client software diskette (for PCs with DOS 3.3+ and Windows 3.1+)

• VLM software diskette (used by remote client software)

The remote client software package enables remote PCs, laptop computers and workstations to dial into a Router and access services on accessible LANs. Unlike LAN-to-LAN connections, which require a dedicated phone line between them, a remote client calls into any modem line on the Router (if it is configured for client operation). Remote client services can be offered inexpensively to many users, using the multiple built-in modem lines offered in the Async Router AR-5.

Remote client access requires a remote user to have an account on the Router. This client account is created by the system administrator. It has a user name, user password, and an optional security call-back number.

Refer to the Reference Guide, which begins on page 137, for more detailed information about managing client databases.

2.6 Operating Requirements

To configure or manage Routers, you need:

• a PC with a serial terminal emulator (such as Windows Terminal), or a serial terminal, or a PC on Ethernet (IPX), or a workstation with telnet on local Ethernet (IP)

• After initial configuration, remote management of Routers requires a PC with RouterVu (IPX networks) or a workstation with telnet (IP networks)

At an Async Router AR-P or AR-5 site, you need':

• a local Ethernet-based IP or IPX network

• a maximum of 5 phone lines

• one power outlet 110VAC to 250VAC

ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

At a Sync Router site, you need:

• a local Ethernet-based IP or IPX network

• a leased line or switched digital line

• a CSU/DSU with a V.35 interface

• two power outlets (110 VAC to 250 VAC: one outlet for the Router and one for the CSU/DSU)

At the opposite end of the synchronous line, you need either:

• a second Router with synchronous interface, or

• another router with synchronous PPP support. Most router vendors offer synchronous PPP options that are compatible with Router’s synchronous interface, but older models may use proprietary synchronous protocols that are not compatible.

For each remote client, you need:

• a PC or lap-top with DOS 3.3+ or Windows 3.1+

• a modem (and Async Client software)

• if TCP/IP remote client operation is required, a third-party package, such as Super-TCP, FTP Software PC/TCP, or others, is also required

• a phone line for the modem

Figure 4-2. If you have a previously configured boot diskette...

If the Router boot diskette has not been previously configured, proceed to Section 4.2.

If your network administrator has prepared a previously configured boot diskette for you, simply insert the diskette into the Router’s diskette drive and start the unit. The Router starts and uploads its configuration parameters from the boot diskette. Your Router is now fully operational. Do not perform the instructions in Chapters 4 and 5, and proceed directly to Chapter 6 to test your installation.

Store the backup boot diskette for the Router in a secure place. The backup boot diskette also contains your Router’s configuration, as configured by your network administrator.

NOTE

If you are the network administrator, you can preconfigure boot diskettes for the remote Router sites in advance, test them, and then mail them to the remote sites. This may be the easiest method to install and configure Routers. Make sure that you also create a backup boot diskette.

PC (3 of Figure 4-1) RouterVu utility

Must be on the same IPX Ethernet as Router

PC (4 of Figure 4-1) Serial terminal utility Must be connected to

or terminal emulation Router’s console port

Serial terminal None Must be connected to (5 of Figure 4-1) Router’s console port

After the Router is initially installed, the system administrator can manage it remotely over the dialup

link or from the local Ethernet LAN, using either:

• telnet for IP networks, or

• RouterVu for IPX networks.

The telnet utility allows you to access and configure Routers remotely over an IP network.

The RouterVu utility allows you to access and configure Routers remotely over an IPX network.

4.2.1 PC/WORKSTATION USING TELNET UTILITY

Figure 4-3. PC/Workstation Using Telnet Utility.

NOTE

This configuration requires the TCP/IP protocol on your LAN.

Before configuring the Router with a PC or workstation using a third-party vendor’s telnet utility, you must use the setaddr utility to set an IP address on the Router’s boot diskette.

setaddr requires a PC/workstation that can read and write 3.5-inch, 1.44-MB DOS diskettes; telnet does not require this capability.

When using telnet to install Router software, the computer using telnet must be a node on the same Ethernet LAN as the Router. You cannot use telnet to configure a Router until an IP address has been assigned, using setaddr.

Procedure

1. Start your DOS-based PC (one that can read and write 3.5-inch, 1.44-MB DOS diskettes).

2. Insert the Router boot diskette into the PC’s diskette drive. We assume you’re using the a: drive. If you’re using the b: drive, substitute b: for a:.

3. Enter:

a:\stacker a:

a:setaddr <RETURN>

4. The setaddr program asks you whether you will be using IPX or IP addresses for telnet.

The Router must have an IP or IPX address before you can access it. This program will set up the initial addresses for your Router.

For IPX addresses on a NetWare network enter 1 For IP addresses on a TCP/IP network enter 2 What kind of addresses will you use (1) or (2)?

Enter 2, and press the RETURN key.

5. The setaddr program asks you for the IP address to be assigned to the Router:

The IP address of the Router must be set before you can telnet in to the box. This program will set up the initial IP address for your Router. Use d.d.d.d notation, (0 <= d <= 255 (decimal)). Enter your IP address:

Enter the Router’s designated IP address, and press the RETURN key. Use dotted quad notation for your IP address: d.d.d.d where d is a decimal number greater than or equal to zero, and less than or equal to 255.

6. Now exit the Stacker utility and unmount the a: drive:

Initial configuration for your Router is now complete. You must now take the boot disk, insert it into your Router and power on the unit. After the Router boots, you can complete the configuration of the Router by using Telnet (IP) or RouterVu (IPX) to access the box.

STACKER doubles your disk capacity!! (type “EXIT” to unmount drive a:)

Enter

exit <RETURN>

7. Remove the Router boot diskette from the PC’s diskette drive.

8. Using a 10BASE-T or AUI cable, connect the Router’s Ethernet port to the local Ethernet LAN.

9. Insert the Router boot diskette into the Router’s diskette drive.

10. Start the Router. Typically, it takes 2-3 minutes for the Router to start. This is normal. After the Router finishes starting, the diskette drive LED will turn off. Do not proceed until this LED turns off.

11. From another TCP/IP host on the network, telnet to the Router’s IP address.

12. When you see a login prompt, type root and press the RETURN key. When prompted for the password, press the RETURN key.

13. Proceed to Chapter 5, and begin to install the software.
