A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E Introducing the AR720 Router Congratulations on purchasing an AR720 Modular Network Access Router—the optimal solution for larger branch and corporate sites with demanding network requirements. This guide will introduce you to the AR720 router and guide you through the most common uses and applications. Getting started will not take long—many applications can be set up in just a few minutes.

The firewall automatically detects and combats a range of denial of service attacks including SYN and FIN flooding, Ping of death, Smurf attacks and port scans. • IPsec-compliant security services. • Calling Line Identification (CLI), which uses the ISDN address of the incoming call to verify that the caller is calling from an authentic location. 5 Encapsulation) protocols.
A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E Getting Connected This section describes how to connect the AR720 router to different physical devices and networks. Before you start, you should be aware that the AR720 router refers to its physical interfaces as ports and these are numbered, starting at 0. Ports on the base unit are numbered first, followed by ports on PICs (Port Interface Cards) in Bay 0 and Bay 1. For example, eth0 is the first Ethernet port and syn1 is the second synchronous port.

To reuse the configuration in a future session, select “Open” from the File menu, select the file name from the list and click “OK”. 6 You can customise Windows™ Terminal further by assigning commonly used router commands to function keys.

Connect the Ethernet LAN to only one of the interfaces. The PIC will automatically sense which interface is in use.
A R 7 2 0 R O U T E R Q U I C K S TA R T G U I D E SHOW SYN=n where n is the synchronous port number. Check that the information displayed is correct. In particular, “State” should be set to “enabled” and “Interface type” should match the transition cable used. 3 Configure a data link layer module, such as PPP (Point-to-Point Protocol), Frame Relay or X.25 LAPB, to use the synchronous interface.
A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E Note: If you wish to make your own ISDN cable, see the AR Router Hardware Reference for a detailed description of how to wire an ISDN interface cable. 2 Check the operation by observing the state of the LEDs on the rear panel of the AT-AR021(U) PIC. The Active LED will be lit when the U interface is activated and operational at the physical layer. The D LED will flicker as control traffic is exchanged with the ISDN switch.
A R 7 2 0 R O U T E R Q U I C K S TA R T G U I D E 0 ASYN 3 Connect the terminal or modem to an asynchronous port on the rear panel of the AT-AR024 ASYN4 PIC using an approved cable. 2 Check that the terminal or modem’s communication settings match the settings of the asynchronous port. By default, asynchronous ports on the AR720 router are set to 9600 baud, 8 data bits, 1 stop bit, no parity and hardware flow control.

A R 7 2 0 R O U T E R Q U I C K S TA R T G U I D E 13 Configuring ISDN This section describes how to configure ISDN on the AR720 router using the command line interface. ISDN on the router requires minimal user configuration, other than selecting a territory, creating call definitions and configuring the Point-toPoint Protocol (PPP) to use the ISDN calls. The lower layers of the ISDN protocol stack (BRI, LAPD and Q.931) are automatically configured when the router starts up.
A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E Directory numbers and subaddresses can be entered with the command: SET Q931=0 NUM1=number NUM2=number SUB1=subaddress SUB2=subaddress The directory numbers and subaddresses must be supplied by the ISDN service provider. If the directory number is a full 10 digit number (3 digit area code plus 7 digit number), the router will append the digits “0101” to the number and attempt SPID initialisation with the result.
A R 7 2 0 R O U T E R Q U I C K S TA R T G U I D E 2 Select the country in which the router is being operated, using the command: SET SYSTEM TERRITORY={AUSTRALIA|CHINA| EUROPE|JAPAN|KOREA|NEWZEALAND|USA} The territory determines which Q.931 profile is used on the ISDN interface. For example, to select the Q.931 profile for New Zealand, use the command: SET SYSTEM TERRITORY=NEWZEALAND Warning: If you are not sure which territory to use, contact your distributor or reseller.
A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E CONFIGURING ISDN DIAL ON DEMAND CONFIGURING ISDN BANDWIDTH ON DEMAND A PPP interface that uses an ISDN call as its physical interface can be configured for dial on demand operation. The ISDN call is activated only when there is data to be transmitted, and is disconnected when the link has been idle for a period of time. A PPP interface can be configured to use up to two B channels on an ISDN Basic Rate interface, to provide bandwidth on demand.
A R 7 2 0 R O U T E R Q U I C K S TA R T G U I D E 17 Configuring an IP Network TCP/IP is the most widely used network protocol. The Internet uses TCP/IP for routing all its traffic. TCP/IP provides a range of services including remote login, Telnet, file transfer (FTP), Email and access to the World-Wide Web. Protocol (PPP) over a wide area link. Each router is attached to an Ethernet LAN on which there is a mixture of PCs and hosts.
A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E and use a terminal emulation program like Windows™ Terminal. 3 Login to the MANAGER account on each router, as described in the AR700 Series Router Quick Install Guide. 4 Collect together the information that you will need to configure IP. We recommend you photocopy the table on the previous page and fill in the details. CONFIGURING IP The following steps are required: on a dial-on-demand ISDN connection this may result in excessive call charges.

A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E Configuring a Novell IPX Network This example illustrates the steps required to configure a pair of AR720 routers to create a Novell® IPX internetwork, using the router’s command line interface. In this scenario, PCs at a remote office need access to a Novell file server at the Head Office site. The two sites are connected by a PPP link over a wide area link—either a dedicated leased line or an ISDN call.
A R 7 2 0 R O U T E R Q U I C K S TA R T G U I D E • Each network in a Novell internet, including all LANs and WAN links, must be assigned a network number. Novell file servers also have an internal network number. These network numbers must be unique across the Novell internet—no two networks or file servers may use the same network number. All devices attached to a network must use the same network number to refer to the network. Check to see what numbers your file servers are using.
A R 7 2 0 R O U T E R Q U I C K S TA RT G U I D E Save the Configuration Save the new dynamic configuration as a script, by entering the command: CREATE CONFIG=IPXCONF.SCP Check that there are two circuits, and for each circuit check that the circuit is enabled, uses the correct interface and encapsulation (for Ethernet interfaces), the network number is correct and “On demand” is set to “no”. If not, then repeat steps 1 through 3.
A R 7 2 0 R O U T E R Q U I C K S TA R T G U I D E 3 Does the file server appear in the IPX service table of the Remote Office router? If the server does not appear in the table, its presence can not be advertised to the local LAN. Check this by typing: SHOW IPX SERVICE This should produce a display like that shown on the previous page.
