1. Connect the mini-DIN8 connector from the Power Adapter to the Power port, and plug the other end into an electrical outlet.

2. Connect one end of one of the RJ-11 cables to the “Line 1" port, and the other end to one of your wall outlets.

Making the Physical Connections 2-3

If you have two phone lines on a single wall outlet, this is the only T elco connection you need to make. The pinout conﬁguration for the lines on the Line 1 port is shown in the following diagram:

1234

5678

Telco 1 Telco 2

Your ﬁrst Telco number is carried on the inner pair and the second number on the outer pair.

3. If you have a second phone line with its own separate wall outlet, and want to use both built-in modems, connect one end of one of the RJ-11 cables to the “Line 2" port, and the other end to your second wall outlet.

4. Connect the Ethernet cable to any of the Ethernet ports on the router. (If you are connecting the router to an existing Ethernet hub, use Ethernet port #1 on the router and set the

crossover switch to the Uplink position.) You should now have: the power adapter plugged in; the Ethernet cable connected between the router and

your computer; and the telephone cables connected between the router and the wall outlets.

5. Insert your Netopia CD and follow the instructions to install an Internet browser and the Adobe Acrobat Reader, if you don’t already have them.

6. Now, run the SmartStart application. SmartStart requires the following:

■ your computer must be Ethernet-capable, that is it must have both an Ethernet card and TCP/IP stack

software. See “Before running SmartStart” on page 3-1.

■ your computer and the Netopia R2020 are powered ON.

■ the computer running SmartStart and the Netopia R2020 to be conﬁgured must be on the same Ether-

net segment; there can be no intervening routers. Repeaters, such as 10Base-T hubs, are acceptable.

Once you’ve connected your router to your computer and your telecommunications line and installed a web browser, you’re ready to run the Netopia SmartStart™ Wizard. The SmartStart Wizard will help you set up the router and share the connection. The SmartStart Wizard walks you through a series of questions and based on your responses automatically conﬁgures the router for connecting your LAN to the Internet or to your remote corporate network.

The SmartStart Wizard will:

■ automatically check your Windows 95, 98, or NT PC’s TCP/IP conﬁguration to be sure you can accept a

dynamically assigned IP address, and change it for you if it is not set for dynamic addressing

■ check the physical connection from your computer to your router without your having to enter an IP address

■ assign an IP address to your router

■ allow you to register with a new ISP if you don’t already have one. For a list of ISPs that support Netopia

Routers in North America, see the Netopia website at http://www.netopia.com.

■ allow you to enter your dial-up telephone numbers and other information, dial up and test your connection

to your chosen ISP or other remote site

Before running SmartStart

Be sure you have connected the cables and power source as described in Step 1 “Connect the Router” guide contained in your Netopia folio.

Before you launch the SmartStart application, make sure your computer meets the following requirements:

PC Macintosh

System software

Notes:

• The computer running SmartStart must be on the same Ethernet cable segment as the Netopia R2020.

Repeaters, such as 10Base-T hubs between your computer and the Netopia R2020, are acceptable, but devices such as switches or other routers are not.

• SmartStart for the PC will set your TCP/IP control panel to “Obtain an IP address automatically” if it is not already set this way. This will cause your computer to reboot. If you have a speciﬁed IP address conﬁgured in the computer, you should make a note of it before running SmartStart, in case you do not want to use the dynamic addressing features built in to the Netopia Router and need to restore the ﬁxed IP address.

Setting up your Router with the SmartStart Wizard 3-3

Setting up your Router with the SmartStart Wizard

The SmartStart Wizard is tailored for your platform, but it works the same way on either a PC or a Macintosh. Insert the Netopia CD, and in the desktop navigation screen that appears, launch the SmartStart Wizard application.

SmartStart Wizard conﬁguration screens

The screens described in this section are the default screens shipped on the Netopia CD. They derive from two initialization (.ini) ﬁles included in the same directory as the SmartStart application ﬁle. Your reseller or your ISP may have supplied you with customized versions of these ﬁles.

■ If you have received a CD or diskette that has been customized by your reseller or ISP , you

can run the SmartStart Wizard directly from the CD or diskette and follow the instructions your reseller or ISP provides. This makes your Netopia R2020 conﬁguration even easier.

■ If you have received only the .ini ﬁles from your reseller or ISP, perform the following:

■ Copy the entire directory folder containing the SmartStart Wizard application from the

Netopia CD to your hard disk.

■ Copy the customized .ini ﬁles to the same directory folder that contains the Smart-

Start Wizard application, allowing the copy process to overwrite the original .ini ﬁles.

■ Run the SmartStart Wizard from your hard disk. You can then follow the instructions

your reseller or ISP provides.

The SmartStart Wizard presents a series of screens to guide you through the preliminary conﬁguration of a Netopia R2020. It will then create a connection proﬁle using the information you supply to it.

Welcome screen. The ﬁrst screen welcomes you to the SmartStart Wizard conﬁguration utility.

Click the Next button after you have responded to the interactive prompts in each screen.

The Help button will display useful information to assist you in responding to the interactive prompts.

When the test succeeds, SmartStart indicates success. If the test fails, the wizard displays an error screen. If the test fails, check the following:

■ Check your cable connections. Be sure you have connected the router and the computer properly, using the

correct cables. Refer to the Step 1 “Connect the Router” sheet in your Netopia R2020 documentation folio.

■ Make sure the router is turned on and that there is an Ethernet connection between your computer and the

router.

■ Check the TCP/IP control panel settings to be sure that automatic IP Addressing (Windows) or DHCP

(Macintosh) is selected. If you are using a Windows PC, SmartStart will automatically detect a static IP address and offer to conﬁgure the computer for automatic addressing. On a Macintosh computer, you must manually set the TCP/IP Control Panel to DHCP. See “Conﬁguring TCP/IP on Macintosh computers” on

page 3-13. If you currently use a static IP address outside the 192.168.1.x network, and want to continue

using it, use the Advanced option to assign the router an IP address in your target IP range. See “Advanced

option” on page 3-8.

■ If all of the above steps fail to resolve the problem, reset the router to its factory default settings and rerun

SmartStart.

Setting up your Router with the SmartStart Wizard 3-5

When the test is successful, you will see the “Manual or Automated Connection Proﬁle screen,” shown below.

Manual or Automated Connection Proﬁle screen. The SmartStart Wizard asks you to select a method of creating a connection proﬁle.

Connect the male HD-15 end of the LocalTalk cable to the Auxiliary port on your Netopia R2020. Connect the other end of the cable to your LocalTalk network. You can use only one connection on the Auxiliary port. You cannot use both the PhoneNET connector and an external modem.

If your LocalTalk network is not based on standard PhoneNET cabling, use a PhoneNET-to-LocalTalk adaptor cable available from Farallon division of Netopia. Connect the adaptor cable’s RJ-11 connector to the AppleT alk cable’s PhoneNet connector. Connect the cable’s mini-DIN-3 connector to your LocalTalk network.

Be sure to observe the standard rules governing maximum cable lengths and limits on the number of nodes on a PhoneNET network. The dual RJ-11 PhoneNET connector allows insertion in the LocalTalk daisy chain, or at the end. If the device is connected at the end of the daisy chain, you must install the accompanying terminator.

Connecting through a Telnet session

Features of the Netopia R2020 may be conﬁgured through the console screens. Before you can access the console screens through Telnet, you must have:

■ a network connection locally to the router or IP access to the router through the WAN port. This could be

the same connection as the one you used with SmartStart. Note: Alternatively, you can have a direct serial console cable connection using the provided console cable

for your platform (PC or Macintosh) and the “Console” port on the back of the router. For more information on attaching the console cable, see “Connecting a local terminal console cable to your router” on

page 5-3.

■ Telnet software installed on the computer you will use to conﬁgure the router

Console-based Management 5-3

Conﬁguring Telnet software

If you are conﬁguring your router using a Telnet session, your computer must be running a Telnet software program.

■ If you connect a PC with Microsoft Windows, you can use a Windows Telnet application or simply run Telnet

from the Start menu.

■ If you connect a Macintosh computer, you can use the NCSA Telnet program supplied on the Netopia

R2020 CD. You install NCSA Telnet by simply dragging the application from the CD to your hard disk.

Connecting a local terminal console cable to your router

You can perform all of the System Conﬁguration activities for your Netopia R2020 through a local serial console connection using terminal emulation software, such as HyperTerminal provided with Windows95 on the PC, or ZTerm, included on the Netopia CD, for the Macintosh.

The Netopia R2020 back panel has a connector labeled “Console” for attaching the Router to either a PC or Macintosh computer via the serial port on the computer. (On a Macintosh, the serial port is called the Modem port or the Printer port.) This connection lets you use the computer to conﬁgure and monitor the Netopia R2020 via the console screens.

This chapter describes how to use the Easy Setup console screens on your Netopia R2020 Dual Analog Router. The Easy Setup console screens provide an alternate method for experienced users to set up their router’s Connection Proﬁles without using SmartStart. After completing the Easy Setup console screens, your router will be ready to connect to the Internet or another remote site.

Easy Setup console screens

Using three Easy Setup console screens, you can:

■ modify a Connection Proﬁle for your Router for the connection to your ISP or remote location;

■ set up IP addresses and IP address serving;

■ password protect conﬁguration access to your Netopia R2020 Dual Analog Router;

How to access the Easy Setup console screens

To access the console screens, Telnet to the Netopia Router over your Ethernet network, or you can physically connect with a serial console cable and access the Netopia Router with a terminal emulation program. See

“Connecting through a Telnet session” on page 5-2 or “Connecting a local terminal console cable to your router” on page 5-3.

Note: Before continuing, make sure that you have the information that your telephone service provider, ISP, or network administrator has given you to conﬁgure the Netopia Router.

The Netopia Router’s ﬁrst console screen, Main Menu, appears in the terminal emulation window of the attached PC or Macintosh when:

■ the Netopia Router is turned on

■ the computer is connected to the Netopia Router

■ the Telnet or terminal emulation software is running and conﬁgured correctly.

6-2 User’s Reference Guide

A screen similar to the following appears:

Netopia R2020 v4.4

Easy Setup proﬁle

The Easy Setup Proﬁle screen is where you conﬁgure the parameters that control the Netopia R2020’s connection to a speciﬁc remote destination, usually an ISP or a corporate site.

On a Netopia R2020 Dual Analog Router you can add up to 15 more connection proﬁles, for a total of 16. See

“Creating a new Connection Proﬁle” on page 7-2.

1. Select Number to Dial and enter the telephone number you received from your ISP. This is the number the Netopia R2020 dials to reach your ISP. Enter the number as you would dial it, including any required preﬁxes (such as area, access, and long-distance dialing codes). You may also use punctuation.

Note: When placing a multi-channel call, the answering equipment must either:

■ be in a “hunt group,” where a single telephone number services multiple lines, or

■ the answering side must implement MP or BAP as a method to advise the calling side what number(s)

to use.

ISPs or corporate IS groups will meet these conditions. For other non-standard dialup connections, you should verify that one or the other of these conditions is true.

2. To enable address translation, toggle Address Translation Enabled to Yes. For more information on Network Address Translation, see “Multiple Network Address Translation and IP Setup” on page 10-1.

3. Select IP Addressing and press Return. From the pop-up menu choose Numbered or Unnumbered (the default).

6-4 User’s Reference Guide

4. Select Local WAN IP Address and enter the local WAN address your ISP gave you. The default address is 0.0.0.0, which allows for dynamic addressing, when your ISP assigns an address

each time you connect. However, you may enter another address if you want to use static addressing.

■ When using numbered interfaces, the Netopia Router will use its local WAN IP address and subnet

mask to send packets to the remote router. Both routers have WAN IP addresses and subnet masks associated with the connection.

■ When using unnumbered interfaces, the Netopia Router will use either its local Ethernet IP address or

its NAT address (if so conﬁgured) and subnet mask to send packets to the remote router. Neither router has a WAN IP address or subnet mask associated with this connection.

Note: If your ISP has not given you their IP or subnet mask addresses, then you can enter an IP address such as 127.0.0.2, and an IP subnet mask such as 255.0.0.0. With these settings the router will get this information dynamically when it connects to the remote site.

5. If your ISP uses unnumbered (system-based routing), select Remote IP Address and enter the IP address your ISP gave you.

Then select Remote IP Mask and enter the IP subnet mask of the remote site you will connect to.

6. Select the PPP Authentication pop-up menu and choose the type of connection security your ISP told you to use (PAP, CHAP , P AP-TOKEN, or CACHE-TOKEN). If you choose any of these authentication methods, go to the next step. If your ISP does not use any of these authentication methods, choose None and skip to the last step. When you create a connection proﬁle from Easy Setup, the default setting is PAP.

7. If your ISP uses PAP or PAP-TOKEN, select Send User Name and enter the user name your ISP gave you to connect. If you selected PAP, select Send Password and enter your password. If you selected PAP-TOKEN, you don’t enter the password now. Your name and password can be up to 32 characters each.

If your ISP uses CHAP , select Send Host Name and enter the user name your ISP gave you to connect. Then select Send Secret and enter the secret (CHAP term for password) your ISP gave you.

If your ISP uses CACHE-TOKEN, select Send User Name and enter the user name your ISP gave you to connect. Select Send Password and enter your password.

8. Select NEXT SCREEN and press Return. The IP Easy Setup screen appears.

IP Easy Setup

The IP Easy Setup screen is where you enter information about your Netopia Router’s:

■ IP address

■ Subnet mask

■ Default gateway IP address

1. Select Ethernet IP Address and enter the ﬁrst IP address from the IP address range your ISP has given you. This will be the Netopia Router’s IP address.

If Network Address Translation is enabled in the Easy Setup connection proﬁle, the Ethernet IP Address defaults to an address within a range reserved by the Internet address administration authority for use within private networks, 192.168.1.1.

Because this is a private network address, it should never be directly connected to the Internet. Using NAT for all your connection proﬁles will ensure this restriction. See “Multiple Network Address Translation and

IP Setup” on page 10-1 of this guide for more information.

2. Select Ethernet Subnet Mask and enter the subnet mask your ISP has given you. The Ethernet Subnet Mask defaults to a standard class C mask (for unlimited user models; smaller, for restricted user models).

3. Select Domain Name and enter the domain name your ISP has given you.

4. Select Primary Domain Name Server and enter the IP address your ISP has given you.

5. The Default IP Gateway defaults to the remote IP address you entered in the Easy Setup connection proﬁle. If the Netopia Router does not recognize the destination of any IP trafﬁc, it forwards that trafﬁc to this gateway.

Do not confuse the remote IP address and the default gateway’s IP address with the block of local IP addresses you receive from your ISP. You use the local IP addresses for the Netopia R2020’s Ethernet port and for IP clients on your local network. The remote IP address and the default gateway’s IP address should point to your ISP’s router.

6. To use DHCP and (if installed) MacIP address serving, toggle IP Address Serving to On. Note: For information about dynamic IP address serving, see “Multiple Network Address Translation and IP

Run the Sds15000.exe program and follow the on screen instructions for enabling the Windows Syslog daemon.

7-14 User’s Reference Guide

When using syslog with a switched connection, if the host you are logging into is located on the WAN, the act of tearing down the call generates WAN events. This requires the torn down line to come back up, effectively making a call that will go up and down continuously. This will only occur when the router tears down the call. If the call is cleared remotely the redial restriction takes precedence and the packets are transparently aged out of the queue.

The following screen shows a sample syslog dump of WAN events:

You can set a Netopia Router to make scheduled connections using designated connection proﬁles. This is useful for creating and controlling regularly scheduled periods when the router can be used by hosts on your network. It is also useful for once-only connections that you want to schedule in advance.

The Netopia R2020 Dual Analog Router can answer calls as well as initiate them. To answer calls, the Netopia

R2020 uses a Default Answer Proﬁle. The Default Answer Proﬁle controls how incoming calls are set up, authenticated, ﬁltered, and more.

Default Answer Proﬁle for Dial-in Connections

The Netopia R2020 Dual Analog Router can answer calls as well as initiate them. To answer calls, the Netopia

R2020 uses a Default Answer Proﬁle. The Default Answer Proﬁle controls how incoming calls are set up, authenticated, ﬁltered, and more.

How the Default Answer Proﬁle works

The Default Answer Proﬁle works like a guard booth at the gate to your network: it scrutinizes incoming calls. Like the guard booth, the Default Answer Proﬁle allows calls based on a set of criteria that you deﬁne.

The main criterion used to check calls is whether they match one of the Connection Proﬁles already deﬁned. If PAP or CHAP authentication is being used, the default proﬁle checks that the incoming call’s name and password/secret match the receive name and password/secret of a Connection Proﬁle. If PAP or CHAP is not being used, an incoming call is matched to a Connection Proﬁle using the remote network’s IP address (that is, the caller is deﬁned as the destination of a particular connection proﬁle).

If an incoming call is matched to an existing Connection Proﬁle, the call is accepted. All of that Connection Proﬁle’s parameters, except for authentication, are adopted for the call.

You could set up the Default Answer Proﬁle to allow calls in even if they fail to match a Connection Proﬁle. Continuing the guard booth analogy, this would be like removing the guards or having them wave all calls in, regardless of their source.

If an incoming call is not required to match a connection proﬁle, and fails to do so, it is accepted as a standard IP connection. Accepted, unmatched calls adopt the call parameter values set in the Default Answer Proﬁle.

To determine the call parameter values that unmatched calls will adopt, customize the Default Answer Proﬁle parameters in the Default Answer Proﬁle screen.

Customizing the default proﬁle

You can customize the Netopia Router’s default proﬁle in the Default Answer Proﬁle screen.

Managing Data Calls 8-5

1. Select Default Answer Proﬁle in the WAN Conﬁguration screen. Press Return. The Default Proﬁle screen appears.

Default Answer Profile Calling Number Authentication... Preferred

Must Match a Defined Profile: Yes

PPP Authentication... PAP

Configure values which may be used when receiving a call in this screen.

2. To enable CNA-authentication, select Calling Number Authentication in the Default Answer Proﬁle screen and choose one of the following settings:

Ignored: Calling Number Authentication (CNA) is not in effect. Preferred: This is the default setting. Authentication is attempted if the calling number is available. If

authentication fails, or the calling number is not available, the call proceeds as usual and the caller may still connect successfully. Use this setting if you expect to receive both regular and CNA-authenticated calls.

Required: Authentication is attempted if the calling number is available. If authentication fails, or the calling number is not available, the Netopia Router disconnects the caller. Use this setting if you require all calls to be CNA-authenticated.

Calling Number Authentication (CNA), is an application of CallerID. It is a method of verifying that an incoming call is originating from an expected site. Using CNA, you can increase the security of your network by requiring that callers not only possess the correct PPP authentication information, but also are calling from a particular physical location.

CNA works by checking the calling number that the Netopia Router receives during the initial setup phase of an incoming call against a set of stored numbers. Each number in the stored set is deﬁned in a speciﬁc connection proﬁle. When a match occurs, the incoming call is handled by the connection proﬁle containing the matched number.

Using CNA can also provide cost savings because calls are not billed during the CNA phase. With CNA, a caller can set up a connection to the Netopia Router without incurring any charges by accessing a dial-back connection proﬁle. If the caller’s rates are higher than those charged to the Netopia Router’s return call, then using CNA has saved the difference.

8-6 User’s Reference Guide

CNA should be available where CallerID services are available. You will need to consult with your telephone service provider to ﬁnd out if your line is provisioned for CallerID.

Also note that if the calling side has instructed the phone company to block delivery of its caller ID, the answering side will not be able to authenticate.

If your line does not support the appropriate service, CNA may not work properly.

3. To force incoming calls to match connection proﬁles, select Must Match a Deﬁned Proﬁle and toggle it to Yes. Incoming calls that cannot be matched to a connection proﬁle are dropped. To allow unmatched calls to be accepted as standard IP or IPX connections, toggle Must Match a Deﬁned Proﬁle to No.

If Must Match a Deﬁned Proﬁle is set to Yes, the answer proﬁle only accepts calls that use the same authentication method deﬁned in the Authentication item. If PAP or CHAP are involved, the caller must have a name and password or secret that match one of the connection proﬁles. The caller must obtain these from you or your network administrator before initiating the call.

For example, if Must Match a Deﬁned Proﬁle is set to Yes, and Authentication is set to PAP, then only incoming calls that use PAP and match a connection proﬁle will be accepted by the answer proﬁle.

If authentication in the Default Answer Proﬁle is set to CHAP, the value of the CHAP Challenge Name item must be identical to the value of the Send Host Name item of the Connection Proﬁle to be matched by the caller.

If Must Match a Deﬁned Proﬁle is set to No, Authentication is assumed to be None, even if you’ve set it to PAP or CHAP. The answer proﬁle uses the caller’s IP address to match a connection proﬁle. However, the answer proﬁle cannot discover a caller’s subnet mask; it assumes that the caller is

not

subnetting its

IP address: Class A addresses are assumed to have a mask of 255.0.0.0 Class B addresses are assumed to have a mask of 255.255.0.0 Class C addresses are assumed to have a mask of 255.255.255.0. Class C address ranges are generally

the most common subnet allocated. If a remote network has a non-standard mask (that is, it uses subnetting), the only way for it to successfully

connect to the Netopia Router is by matching a connection proﬁle. In other words, you will have to set up a connection proﬁle for that network.If Must Match a Deﬁned Proﬁle is set to No, you can also set the following parameters for accepted calls that do not match a connection proﬁle:

You use this feature to track ﬁrst minutes (an ISDN tariff factor) and additional minutes or megabytes per time period for initiated data and voice calls, either through the Web-based management pages or the console-based management screens.

You can conﬁgure budgets to be:

■ Enforced, meaning that when you reach the usage limit for the assigned time period, the Connection Proﬁle

will allow no more connections. If the budget is not enforced, the system will merely keep track of its usage. To enforce this budget, check the Enforced checkbox.

■ in Override mode. Checking this option allows you to exceed your budget during the current time period

without tearing down active connections. At the end of the current time period this option is automatically deactivated. If you want to be able to exceed your enforced budget again, you must check this option for each new time period.

Checking Override disables call blocking, even if the call is over its limit. The override ﬂag is automatically reset to be off at the start of a new period. This is so that you don’t need to disable Enforced to by-pass the limit and or remember to turn it back on when the new period starts.

■ set to a predeﬁned Limit of minutes of usage

■ set to the Time Period, weekly or monthly, that you specify for your own budgeting requirements

■ started on a speciﬁc day of the week or month by selecting the day you want to start from the pull-down

menu. If you set a weekly schedule, you choose the day of the week to start it; if you set a monthly

schedule, you choose the day of the month to start it.

Click the Submit button to enable your entries and be returned to the Connection Budgets page or click the Cancel button to discard all your entries. Click the Reset button to reset all counters and archives to zero.

the Budget Account pull-down menu.

■ Select the Format you want to view, either 1st Minute/Additional Minutes or Channel 1/Channel 2.

The Netopia R2020 records certain relevant occurrences in event histories. Event histories are useful for diagnosing problems because they list what happened before, during, and after a problem occurs. You can view two different event histories: one for the router’s system and one for the WAN. The Netopia R2020’s built-in battery backup prevents loss of event history from a shutdown or reset.

The router’s event histories are structured to display the most recent events ﬁrst and to make it easy to distinguish error messages from informational messages. Error messages are preﬁxed with an asterisk. Both the WAN Event History and Device Event History pages retain records of up to 128 of the most recent events.
