About the MicroRouter 2270R

Congratulations on your purchase of the MicroRouter 2270R multiport wide area router with integrated Fractional/Full T1 CSU/DSU. The MicroRouter 2270R supports the IP, IPX, AppleTalk, and DECnet network protocols, with leased-line and/or dial-on-demand operation using the PPP, Frame Relay and/or SMDS wide area protocols.

A Note About Firewalls

The MicroRouter 2270R can be configured to be a very effective packet screening firewall. However, you must carefully set up your network and add packet filters in order for it to be effective in this role.

THE SHIPPING C ONFIGURATION I N YOUR MICROROUTER 2270R DOES NOT PROVIDE AUTOMATIC FIREWALL PROTECTION. YOU MUST FIRST PROGRAM YOUR ROUTER TO WORK IN THIS ROLE ON YOUR NETWORK.

Note: Due to the nature of the IP protocol, IP packet filtering can

be quite complicated. If you are attempting to design and implement a comprehensive set of filters, or an Internet Firewall, there are a number of references you should consult. Two good starting points are: Building Internet Firewalls Associates, 1995, and Firewalls and Internet Security: Repelling the Wily Hacker, by William R. Cheswick and Steven M. Bellovin, Addison-Wesley Publishing Company, 1994.

A Note About On-Demand Internetworking

The MicroRouter 2270R can be configured to provide cost effective on-demand connections over a wide area communications link (typically a voice phone line, a switched 56 line, or an ISDN line). Your network traffic and the configuration you place in the router will determine how often and for how long such a link is connected.

YOU SHOULD CAREFULLYMONITOR PHONE LINE USAGE TO BE SURE THAT YOUR ROUTER CONFIGURATION IS ALLOWING THE ROUTER TO DROP THE COMMUNICATIONS LINK WHEN IT ISN’T NEEDED.

MicroRouter 2270R Installation Overview

This manual will help you install the MicroRouter 2270R to connect two local Ethernets to one or two remote networks and/or remote PPP client computers. These connections can be made to other Compatible Systems routers, routers from other vendors, or PPP compliant dial-in software packages running on a variety of computers. The wide area interfaces on the MicroRouter 2270R may be used to interconnect your network with other corporate networks, and to make your network’s resources available to dial-in clients.

In short, the installation steps are:

1. Install the MicroRouter hardware and connect the primary WAN

port’s built-in T1 CSU/DSU to a fractional T1 or full T1 line.

2. Select the management method you wish to use with the router. If

you want to use the CompatiView management software, you must install the software on a Windows PC which is connected to your network.

3. Configure the MicroRouter LAN and WAN parameters using the

management method you have chosen.

4. Connect the secondary WAN port’s RS-232 to an external l ine

communication device (including modems, 56K CSU/ DSU’s, and ISDN Terminal Adapters).

Needed For Installation

Before connecting the MicroRouter 2270R to your network, you need to make sure that you have the necessary equipment for connecting to the local Ethernet(s) and the fractional or full T1 line, and/or a wide area transmission device (modem, 56K CSU/DSU, ISDN Terminal Adapter).

Chapter 2 - Getting Started 7

Ethernet Connection Requirements

The MicroRouter 2270R’s Ethernet interfaces directly support 10BaseT twisted-pair Ethernet. Other Ethernet cabling types (such as thin Ethernet, thick Ethernet, fiber optic cabling or pre-10BaseT twisted-pair) can be supported using a 10BaseT mini-hub or other conversion device.

10Base-T Twisted-Pair Ethernet

To connect the router's Ethernet interface to twisted-pair Ethernet cabling you will need an unshielded twisted-pair station cable that is connected to a 10BaseT-compatible twisted-pair hub.

Note: Ethernet cables and cable connectors are not supplied with

the MicroRouter product. Please contact your reseller or your Compatible Systems representative for information on obtaining the correct Ethernet cabling supplies.

T1 Line Connection Requirements

The MicroRouter 2270R includes an integrated fractional or full T1 CSU/DSU. To connect this interface to a T1 line, you will need an RJ-45 jumper cable. A straight-through Category 5 10BaseT jumper cable will work in this application.

Note: The MicroRouter 2270R includes loopback features which

can be used to check the functionality of your T1 line. Before attempting to route network traffic, use these features to check the line’s basic integrity.

Other Telco Line Connection Requirements

In order to connect to non-T1 wide area transmission lines, you must connect the router’s secondary wide area port to a modem, 56K CSU/DSU, or ISDN TerminalAdapter. Which of these devices you use depends on the type of telco line.

Note: Before attempting to connect the MicroRouter 2270R’s

secondary port to a leased telco line, use the loopback featuresof your external CSU/DSU to check the line. This can save you a considerable amount of time, since the more equipment you have on the line, the more difficult it becomes to determine where a problem is occurring.

8 Chapter 2 - Getting Started

The MicroRouter 2270R secondary port is an RS-232 sync/async interface. The RS-232 interface is capable of communicating to another router or a PPP client machine over a modem, 56K CSU/DSU, or ISDN Terminal Adapter.

RS-232 Interface

The MicroRouter 2270R includes one DB-25 to DB-25 RS-232 sync/async cable. This cable supports RS-232 asynchronous modems, synchronous leased and switched 56K CSU/DSU’s, and ISDN Terminal Adapters. It can also be used to connect the router’s auxiliary interface to a PC running terminal emulation software, or to a dumb terminal.

Note: Please use only the supplied DB-25 cable when connecting

your line communication device to the MicroRouter 2270R’s RS-232 interface. The cables provided with other equipment will generally not have the same internal connections.

Chapter 3 - Network Installation 9

Chapter 3 - Network Installation

MicroRouter 2270R Back Panel

This section of the manual describes how to connect the MicroRouter 2270R to your Ethernet network and your wi de area communications device(s). In summary, the steps for installation are:

1. Make sure the router is powered down and not connected to any power source.

2. Connect the router to the Ethernet network(s).

3. Connect the router to the T1 line.

4. Connect the router’ssecondary port to a wide area line communications device (if used).

5. Power up the line communications device (if used).

Note: You should either wait to connect a synchronous l ine device

such as a CSU/DSU until after the interface has been configured as a synchronous port, or power up the router before powering up the CSU/DSU. (See Chapter 6 - Basic Configuration Guide for more information on configuring the router.)

6. Plug in the power cable and power up the router.

Placing the R outer

The MicroRouter 2270R is meant to be left stand-alone on a desktop or equipment table.

Note: When stacking other equipment on the MicroRouter 2270R,

do not exceed 25 pounds of evenly distributed weight on top of the router. Additional weight may bend the case.

10 Chapter 3 - Network Installation

Connecting the Router to the Ethernet

If your twisted-pair hub is already in place, you can connect the router to an active network without interrupting network activity. The router must be powered off.

Connecting to Twisted-Pair Ethernet

Before connecting the router to twisted-pair cabling you need an unshielded twisted-pair cable that is already connected to your 10BaseT-compatible twisted-pair hub.

To connect the router to the twisted-pair network, simply plug the twisted-pair cable into the RJ-45 Ethernet connector on the back of the unit.

Connecting the Router to a T1 Line

To connect the router to the T1 line, you need a four wire jumper cable that is already connected to the RJ-45 jack which was installed by your telephone company. The router must be powered off. Simply plug the jumper cable into the RJ-45 WAN 0 connector on the back of the MicroRouter 2270R.

Connecting a Line Device to the Secondary Port

The MicroRouter 2270R supports lower speed synchronous/asynchronous operation over a secondary RS-232 connector (WAN1). This port independently supports the PPP and Frame Relay link protocols.

Connecting Devices to the RS-232C Interface

This interface -- WAN 1 -- can be used to connect to synchronous or asynchronous line communications devices at rates up to 256Kbps (sync), or 230.4 Kbps (async). Examples include modems, leased or switched 56K CSU/DS U’s, and ISDN Terminal Adapters.

Note: If connecting to a synchronous device such as a CSU/DSU,

the router must first be configured for synchronous operation before connecting to the device. See Chapter 6 - Basic Configuration Guide for configuration information.

You may select either dial-on-demand, always up (i.e., redial if down), or leased line operation. This interface may also be set to receive ISDN or switched-56 incoming calls.

To connect a device, first make sure that both units are powered off. Then, simply connect the supplied RS-232 cable between t he router and the d evice.

Chapter 3 - Network Installation 11

Note: The MicroRouter 2270R RS-232 interfaces require that your

asynchronous line communications device be set to supply the RS-232 DCD signal when a connection has been made. A synchronous RS-232 device should be set to provide DSR.

Note: The MicroRouter 2270R includes a special cable to facilitate

connections to RS-232 line communications devices. This cable includes support for several asynchronous and synchronous control signals. Off-the-shelf cables generally do not support these signals.

Connecting an Out-of-Band Management Console

If you wish to connect an out-of-band management console, use the supplied cable and connect to the Console interface on the back of the MicroRouter 2270R. You can use a dumb terminal or a computer equipped with VT100 terminal emulation.

The default settings for the Console interface are VT100 terminal emulation, 9600 bps, 8 bits, no parity, 1 stop bit, no Flow Control.

Powering Up the Router

Power up any modem, CSU/DSU, or TA before powering up the router. This allows the router to immediately sense whether its secondary interface is connected. The exception to this rule is when connecting an RS232 interface to a CSU/D SU. In such a case, you must power up the router before take approximately one minute to become visible to CompatiView.

powering up the CSU/DSU. At power-up, the router will

Note: If you want to use Telnet as a management method, you must

first configure an IP address into the router using an out-of-band console, or reconfigure the IP address on an IP host or workstation on the same Ethernet segment as the router. See Chapter 5 - Command Line Management for more information.

Chapter 4 - CompatiView SoftwareInstallation 13

Chapter 4 - CompatiView Software Installation

All of the routers in Compatible Systems’ internetworking and VPN families, including all R ISC Router and MicroRouter models, can be managedfroma single GUI managementplatformcalledCompatiView. CompatiView for Windows is included on the CD-ROM which was shipped with your MicroRouter 2270R.

Note: An older version of CompatiView for Mac OS was included

on the CD-ROM shipped with your router, but does not contain some of the features o f the newest Windows version.

CompatiView for Windows

CompatiView for Windows allows you to manage the MicroRouter 2270R from an IBM-compatible PC running Windows 95/98 or Windows NT. The PC can either be configured as an IPX client on a Novell NetWare internet, or as an IP WinSock client on an IP internet.

System R equirements

In order to successfully run C ompatiView for Windows, you need:

• IBM PC or compatible w/486 or later processor

• Microsoft Windows 95/98, or Windows NT installed

• VGA or better monitor

• IP - A WinSock-compatibletransport stack

- and/or -

• IPX - A Netware or Microsoft Client installation

Note: To choose the active transport protocol on a Windows

machine which has both IPX and IP installed, select “Options” from the Database menu and click the General tab. Then select the appropriate radio button under “Transport.”

Installation and Operation

The Windows version of the CompatiView program can be found in the Network Management/CompatiView/Windows directory on the CD-ROM that was included with your MicroRouter 2270R.

14 Chapter 4 - CompatiViewSoftware Installation

Run the auto-installation program (CV5x file) by double-clicking on it. The installation program will ask you to select (or create) a directory in which it should locate CompatiView and its associated files and database subdirectory.

Once the installation is complete, double-click on the CompatiView icon to open the program. For further information on using CompatiView, see the CompatiView Management Software Reference Guide included with your router.

Note: For an up-to-date description of the changes (if any) made to

Windows system files by the installation program, see the README.TXT file located in the CompatiView installation directory.

Transport Protocols and CompatiView

CompatiView will be able to use the transport protocol (IP or IPX) you have selected to access Compatible Systems products anywhere on your internetwork. Depending on your security setup, you may also be able to use the IP transport option to manage devices across the Internet.

The IP protocol does not provide a method for CompatiView to automatically discover the router. To initially contact the router over IP using CompatiView, you must first enter a valid IP address into the router. You can do this either on a console directly connected to the router or by setting a workstation’s IP address to 198.41.12.2 with a Class C subnet mask (255.255.255.0) so that it can communicate over Ethernet with 198.41.12.1 (the shipping default of Ethernet 0). After setting the router’s IP address, be sure to change the workstation’s configuration back to its original settings.

The IPX protocol does the router. Compatible Systems devices are configured to autoseed the two most common IPX frame types upon startup (802.2 and 802.3 (raw)). If CompatiView has the IPX/SPX protocol selected as its transport, it will be necessary to either power up the router before powering up the workstation, or reboot the workstation after the router has completed its boot sequence. This process will ensure that the workstation and the router have the proper IPX network bindings for communication.

Chapter 5 - Command Line Management 15

Chapter 5 - Command Line Management

The command line interface allows you to configure and monitor the router in-band via Telnet or out-of-band with a terminal connected to the Mi croRouter 2270R’s Console interface.

Note: Proper syntax is vital to effective operation of command line

management. Case is not significant – you may enter commands in upper case, lower case, or a combination of the two.

Out-of-Band Command Line Management

You can use command line management and text-based configuration out-of-band as a permanent management tool, or only temporarily in order to set the router’s IP parameters to allow in-band Telnet access.

In order to access the command line out-of-band, do the following:

1. Set a terminal or a PC equipped with VT100 terminal emulation to a baud rate of 9600, 8 b its, no parity, 1 stop bit and no Flow Control.

2. Connect it to the router’s Console interface using the cable which was supplied with the MicroRouter 2270R.

3. Press the <Return> key one or two times.

4. Enter the default password letmein at the password prompt. The command line interface prompt will appear on the screen.

If you plan to use out-of-band access for ongoing management of your router, you can find further information on configuring your router in Chapter 6 - Basic Configuration Guide. Otherwise, see the section later in this chapter on Setting Up Telnet Operation for information on setting the router to allow Telnet access from hosts on its network.

16 Chapter 5 - Command Line Management

Temporarily Reconfiguring a Host for Command Line Management

You can temporarily reconfigure an IP host in order to set the router ’s IP parameters to allow in-band Telnet access.

If you wish to set the router’s basic IP parameters in this fashion, the host must be on the s ame Ethernet segment as one of the router’s Ethernet interfaces. You can then do the following:

1. Set the host’s IP address to 198.41.12.2, with a Class C subnet mask (255.255.255.0) and then Telnet to 198.41.12.1.

2. Enter the default password letmein at the password prompt. The command line interface prompt will appear on the screen.

3. Use the configure command and set the IPAddress, SubnetMask, and IPBroadcast keywords in the IP Ethernet 0 (and/or Ethernet

1) section.

4. Use the save command to save the changes to the device’s Flash ROM.

5. Change the host’s configuration back to its original settings.

See the next section (Setting Up Telnet Operation) for information on setting the router to allow Telnet access from hosts on its network.

SettingUpTelnetOperation

Telnet is a remote terminal communications protocol based on TCP/IP. With Telnet you can log into and manage the MicroRouter 2270R from anywhere on your IP internetwork, including across the Internet if your security setup allows it. To manage the router with Telnet, you must:

1. Run Telnetclient software on your local computer, which will communicate with the Telnet server built into the MicroRouter 2270R.

2. You must also set some basic IP parameters in the router. The required parameters for Telnet access to an interface are the IP address, IP subnet mask, and IP broadcast address. There are several ways to set them.

• You may set them using text-based configuration either

out-of-band via the Console interface or in-band via a reconfigured IP host. Instructions for setting up these two methods were given earlier in this chapter. Once you have set up the command line interface, do the following:

A. Use the configure command and set the IPAddress,

Chapter 5 - Command Line Management 17

SubnetMask,andIPBroadcastkeywords in the IP Ethernet 0 (and/or Ethernet 1) section.

B. Use the save command to save the changes to the device’s

Flash ROM.

• You may also use CompatiView from a reconfigured IP host

(if using the IP transport protocol), or anywhere on your network (if using the IPX transport protocol). Instructions for these two methods are given in Chapter 4 - CompatiView Software Installation.

• With CompatiView, basic IP parameters can be set using the

TCP/IP Routing: Ethernet 0 Dialog Box. Use the Save to/Device option under the File menu to save the changes.

After you have set these IP parameters and saved the changes, you can use Telnet to access the router from any node on your IP network. Invoke the Telnet client on your local host wi th the IP address of the router you wish to manage.

Chapter 6 - Basic Configuration Guide 19

Chapter 6 - Basic Configuration Guide

This chapter briefly explains the major parameters that must be set in order to use the router.

Detailed information on the meaning of the router’s parameters is provided in the CompatiView Management Software Reference Guide and the Text-Based Configuration and Command Line Management Reference Guide. You should use this list as a starting point to look up more specific information in the other documents.

If you need more general information on IP , IPX, AppleTalk or wide area protocols, see the Appendices in the CompatiView Management Software Reference Guide.

There are a number of parameter settings which are optional, in the sense that they are not required for all installations. These settings are not covered in this chapter.

In this chapter:

CV =CompatiView TB = Text-Based Configuration

In order to successfully connect to an Internet Service Provider (ISP), you must use router configuration parameters which will be provided by the technical staff of the ISP. These parameters must include all I P addresses, WAN settings, and any applicable authorization routines. Please check with your ISP before ration of your MicroRouter 2270R.

Note:This Basic Configuration Guide does not include information

on setting up packet filters for using the router as a Firewall. See the

CompatiView Management Software Reference Guide or Text-Based Configuration and Command Line Management Reference Guide

regarding IP packet filters for more information.

Ethernet Interface Configuration

Ethernet interfaces are considerably easier t o set up than wide area interfaces s ince there are fewer choices that need to be made regarding communications protocols and parameters. We recommend that you begin by configuring any Ethernet interface parameters before proceeding to configure WAN interface parameters.

20 Chapter 6 - Basic Configuration Guide

IP Protocol

Required for IP

These parameters set the basic address characteristics of the interface. They provide enough information for another IP node to find the interface (such as a Telnet client), but not enough information for routing to take place.

•IPaddress

• IP subnet mask

• IP broadcast address

CV: Use the TCP/IP Routing: Ethernet Dialog Box to set these param-

eters.

TB: Use the configure command and the IPAddress, SubnetMask,

and IPBroadcast keywords in the IP Ethernet 0 (and/or Ethernet 1) section.

Suggested for IP

These parameters help supply information about the segment that the interface is connected to. With this information, routing can take place.

• Set IP RIP 1 or IP RIP 2

• IP Static Routes

CV: Use the TCP/IP Routing: Ethernet Dialog Box to set RIP,and the

IP Static Routing Dialog Box (under Global/IP Static Routes) to set static routes.

TB: Use configureand set the RIPVersion keyword for IP Ethernet

0 (and/or Ethernet 1) section. Use edit config and add static routes in the IP Static section.

IPX Protocol

Required for IPX

There are generally no required changes from t he shipping Ethernet configuration for IPX. The Ethernet interface will autoconfigure to use the two most common IPX frame types, and will autoadapt to conditions on the Ethernet.

Chapter 6 - Basic Configuration Guide 21

Suggested for IPX

You may want to set your own network numbers, rather than using the autoconfigured values. You may also want to turn off unused frame types.

CV: Use the IPX Routing: Ethernet 0 Dialog Box. TB:Useconfigure and set keywords in the IPX Ethernet 0 (and/or

Ethernet 1) section.

AppleTalk Protocol

Required for AppleTalk

There are generally no required changes from t he shipping Ethernet configuration for AppleTalk. The Ethernet interface will autoconfigure to use AppleTalk Phase 2, and will autoadapt to conditions on the Ethernet.

Suggested for AppleTalk

You may want to set your own network numbers, rather than using the autoconfigured values. You may also want to use more meaningful zone names.

CV: Use the AppleTalk Routing: Ethernet 0 Dialog Box. TB: Use configure and set keywords in the AppleTalk Phase 2

Ethernet 0 (and/or Ethernet 1) section.

DECnet Protocol

Required for DECnet

The router’s shipping configuration does not have DECnet turned on. You must turn it on and set several DECnet parameters.

• Set DECnet on (globally, and for this port)

• Set DECnet area

• Set DECnet node

CV: Use the DECnet Routing Dialog Box (under Global/DECnet

Routing) and the DECnet: Ethernet Dialog Box.

TB: Use configure and set the Enabled, Area,andNode keywords in

the DECnet Global section.

Note: Setting DECnet on for any port with the command line also

sets DECnet on globally. In CompatiView you must set a global parameter and a port-specific parameter.

22 Chapter 6 - Basic Configuration Guide

Suggested for DECnet

Setting the parameters above should be adequate for most installations.

WAN Interface Configuration

In order to use a WAN interface, you may first need to set some physical parameters and then s et up the link and protocol parameters.

There are differences between the capabilities of the built-in T1 CSU/DSU WAN interface and the RS-232 WAN interface. The T1 interface can only be used with lines which run at fractional or full T1 rates. The RS-232 interface can be run synchronously or asynchronously, at rates up to 256Kbps (sync) or 230.4Kbps (async).

InternalT1CSU/DSU(WAN0)PhysicalCommunications Settings

Required for Dedicated Line Operation

No changes from the default values are required for standard operation over a full T1. The default values are listed in Appendix A.

Suggested for Dedicated Line Operation

Changing to fractional T1, different coding or framing, etc., may be required for a particular installation.

CV: Use the Physical Configuration: WAN 0 Dialog Box. TB: Use configure and the T1 Interface WAN 0 section.

RS-232 (WAN 1) Physical Communications Settings

You may need to set the baud rate, sync/async operation, and o ther physical communications parameters for the WAN interface. These parameters will depend on the line communications device you are using.

Note: Frame Relay is presently supported in the MicroRouter

2270R only via synchronous operation. An external clock signal is generated for Frame Relay.

CV: Use the Physical Configuration: WAN 1 Dialog Box. TB: Use configure and set the LinkType keyword or other keywords

in the RS232 Interface WAN 1 section.

Chapter 6 - Basic Configuration Guide 23

PPP Configuration

This section covers the settings required for PPP (point-to-point) protocol operation of the WAN interfaces.

Internal T1 CSU/DSU (WAN 0) Link Configuration

Required for Dedicated Line Operation

This is the only mode of operation supported via the built-in T1 CSU/DSU.

• Set PPP connection

CV: Use the Link Configuration: WAN 0 Dialog Box. TB: Use configure and set the Mode keyword in the Link Config

WAN 0 section.

Suggested for Dedicated/Leased Line Operation

Dedicated line operation generally does not require additional parameters for operation.

RS-232 (WAN 1) Link Configuration

Required for Dedicated/Leased Line Operation

Dedicated line operation is the simplest to set up.

• Set Dedicated connection

• Set PPP connection

CV: Use the Link Configuration: WAN 1 Dialog Box. TB: Use configure and set the Mode and ConnectMode keywords in

the Link Config WAN 1 section.

Suggested for Dedicated/Leased Line Operation

Dedicated line operation generally does not require additional parameters for operation.

Required for Dial-On-Demand Operation

This mode of operation is only supported on the WAN 1 RS-232 interface. Incoming dial-on-demand operation requires only slightly more information than dedicated line setup. Outgoing dial-on-demand requires additional information (see the suggested settings below).

• Set dial-up connection

• Set PPP connection

24 Chapter 6 - Basic Configuration Guide

• Set to allow dial-in and/or dial-out

CV: Use the Link Configuration: WAN 1. TB: Use configure and set the Mode, ConnectMode, DialIn and/or

DialOut keywords in the Link Config WAN 1 section.

Suggested for Dial-On-Demand Operation

This mode of operation is only supported on the WAN 1 RS-232 interface. Outgoing dial-on-demand requires some additional information.

• Create dial-out script

• Set dialing method

• Set dial-out script to be used

• Set inactivity time

CV: Usethe Link Configuration: WAN1 Dialog Box to set t he dialing

method and to select a chat script (once you have created one). Use the WAN Chat Scripts Dialog Box (under Global/WAN Chat Scripts) to create your chat script.

TB: Use configure and then set the Dialing, DialOutScript,and

DropInactkeywords in the Link Config WAN 1 section. Use edit config and create a Chat section to contain your dialing

script.
