The Netopia 4741 Voice/Data Integrated Access Devices (IADs) make it possible for small businesses to take advantage of the advanced communications technologies previously limited to larger organizations. By integrating multiple voice connections and high-speed Internet access on one DSL line, businesses can squeeze the most out of their communications budget.

The Netopia 4741 ADSL Integrated Access Device combines a complete telephone system with a business-class data router to deliver a customized package of business communications services over DSL. The Netopia 4741 supports the broad array of phone features offered through your service provider and uses your existing analog telephone equipment. The Netopia 4741 includes Netopia's sophisticated data routing engine optimized for small and medium size business needs. These business-class features include IP routing, ﬁrewall, NAT, MultiNAT, DHCP and both PPTP and IPSec VPN functionality.

This section covers the following topics:

Small- to medium-sized businesses need two kinds of services: Internet presence and voice telephony. But they don't need the additional burden of maintaining switching equipment or administering IP and voice services for their ofﬁces. An Integrated Access Device (IAD) that offers high-speed DSL for IP connectivity and a voice telephone system that somebody else (the phone company) administers is the simple solution.

At the phone company's central ofﬁce, where all the big switch gear is, there are two kinds of switches for the two kinds of services, voice and data. The IAD must be capable of communicating with a wide array of possible combinations of voice and data switches.

An IAD combines the voice telephony features of a telephone system with the data routing features of an IP data router. The device uses a single outside line connection to carry all voice and data transmissions. If the device uses a DSL interface, it can carry all of these services over a single existing copper telephone line by regulating the ﬂow of voice and data packets on the copper wire for voice and data trafﬁc.

The Netopia 4741 ADSL Integrated Access Device is that device: a Centrex-based system combined with an ADSL internet router.

The Netopia 4741 ADSL Integrated Access Device provides the following features:

Support for ordinary analog phone equipment.

that small businesses use today. No expensive handsets to order, no new interface to learn.

Once you have set up your physical local area network, you will need to conﬁgure the TCP/IP stack on each client workstation connected to your Netopia 4741. This chapter describes how to conﬁgure TCP/IP for both Windows-based and Macintosh computers.

This chapter explains the following topics:

■ “Conﬁguring TCP/IP on Windows-based Computers” on page 3-2

■ “Conﬁguring TCP/IP on Macintosh Computers” on page 3-5

Page 22

3-2 Administration Guide

Conﬁguring TCP/IP on Windows-based Computers

Conﬁguring TCP/IP on a Windows computer requires the following:

■ An Ethernet card (also known as a network adapter)

■ The TCP/IP protocol must be “bound” to the adapter or card

Conﬁguring TCP/IP on Macintosh Computers

The following is a quick guide to conﬁguring TCP/IP for MacOS computers. Conﬁguring TCP/IP in a Macintosh computer requires the following:

■ You must have either Open Transport or Classic Networking (MacTCP) installed.

Note: If you want to use the Dynamic Host Conﬁguration Protocol (DHCP) server built into your Netopia 4741 to assign IP addresses to your Macintoshes, you must be running Open Transport, standard in MacOS 8 and optional in earlier system versions. You can have your Netopia 4741 dynamically assign IP addresses using MacTCP; however, to do so requires that the optional AppleTalk kit be installed which can only be done after the router is conﬁgured.

■ You must have built-in Ethernet or a third-party Ethernet card and its associated drivers installed in your

Macintosh.

Dynamic conﬁguration (recommended)

The Dynamic Host Conﬁguration Protocol (DHCP), which enables dynamic addressing, is enabled by default in the router. To conﬁgure your Macintosh computer for dynamic addressing do the following:

1. Go to the Apple menu. Select Control Panels and then TCP/IP.

2. With the TCP/IP window open, go to the Edit menu and select User Mode. Choose Basic and click OK.

3. In the TCP/IP window, select “Connect via: Ethernet” and “Conﬁgure: Using DHCP Server.”

Note: You can also use these instructions to conﬁgure other computers on your network to accept IP addresses served by the Netopia 4741.

Readying Computers on Your Local Network

PC and Macintosh computers must have certain components installed before they can communicate through the Netopia 4741. The following illustration shows the minimal requirements for a typical PC or Macintosh computer.

Application software

TCP/IP stack

Ethernet

Your PC or Macintosh computer

To the Netopia 4741

Application software: This is the software you use to send e-mail, browse the World Wide Web, read newsgroups, etc. These applications may require some conﬁguration. Examples include the Eudora e-mail client and the Web browsers Microsoft Internet Explorer and Netscape Navigator.

TCP/IP stack: This is the software that lets your PC or Macintosh computer communicate using Internet protocols. TCP/IP stacks must be conﬁgured with some of the same information you used to conﬁgure the Netopia 4741. There are a number of TCP/IP stacks available for PC computers. Windows 95 includes a built-in TCP/IP stack. See “Conﬁguring TCP/IP on Windows-based Computers” on page 3-2. Macintosh computers use either MacTCP or Open Transport. See “Conﬁguring TCP/IP on Macintosh Computers” on page 3-5.

Ethernet: Ethernet hardware and software drivers enable your PC or Macintosh computer to communicate on the LAN.

Once the Netopia 4741 is properly conﬁgured and connected to your LAN, PC and Macintosh computers that have their required components in place will be able to connect to the Internet or other remote IP networks.

Connecting through a Telnet Session

Features of the Netopia 4741 can 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.

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 Console Cable to Your Device” on page 5-3.

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

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 T elnet application or simply run T elnet

from the Start menu.

Page 35

Console-Based Management 5-3

■ If you connect a Macintosh computer, you can use the NCSA Telnet program supplied on the Netopia 4741

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

Connecting a Console Cable to Your Device

You can perform all of the system conﬁguration activities for your Netopia 4741 through a local serial console connection using terminal emulation software, such as HyperTerminal provided with Windows 95, 98, 2000, or NT on the PC, or ZTerm for Classic MacOS, included on the Netopia CD, for Macintosh computers.

The Netopia 4741 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 computer, the serial port is called the Modem port or Printer port.) This connection lets you use the computer to conﬁgure and monitor the Netopia 4741 via the console screens.

Domain Name: Primary Domain Name Server: 0.0.0.0 Secondary Domain Name Server: 0.0.0.0

Default IP Gateway: 0.0.0.0 IP Address Serving: On Number of Client IP Addresses: 100

1st Client Address: 192.168.1.100

PREVIOUS SCREEN NEXT SCREEN Enter an IP address in decimal and dot form (xxx.xxx.xxx.xxx).

Set up the basic IP & IPX attributes of your Netopia in this screen.

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.

The Ethernet IP Address defaults to an address (192.168.1.1) within a range reserved by the Internet address administration authority for use within private networks.

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” 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 mask derived from the class of the Ethernet IP address you entered in the previous step.

3. Press the Down arrow key until the editable ﬁeld labeled Domain Name is highlighted.

4. Type the Domain Name your ISP gave you. Press Return. The next ﬁeld Primary Domain Name Server will be highlighted.

5. Type the Primary Domain Name Server address your ISP gave you. Press Return. A new ﬁeld Secondary Domain Name Server will appear. If your ISP gave you a secondary domain name server address, enter it

here. Press Return until the next ﬁeld Default IP Gateway is highlighted.

6. For a PPP connection, if you do not enter a Default IP Gateway value, the router defaults to the remote IP address you entered in the Easy Setup connection proﬁle. If the device 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 IP Gateway’s address with the block of local IP addresses you receive from your ISP. You use the local IP addresses for the Netopia 4741’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.

7. Toggle IP Address Serving to On or Off, depending on whether you want the device’s IP address server to supply dynamic IP addresses to your client workstations. Normally, you would accept the default On so that workstations on your LAN can use a single IP address assigned by your ISP to connect to the Internet.

8. The IP address server will provide 100 IP addresses automatically to workstations on your LAN. You only need to change the Number of Client IP Addresses if you have some other IP addressing scheme.

9. By default, the 1st Client Address is 192.168.1.100, based on the device’s default IP address of

192.168.1.1. You only need to change this if you have some other IP addressing scheme.

10. Press the Down arrow key until you reach NEXT SCREEN. Press Return.

Easy Setup Security Conﬁguration

The Easy Setup Security Conﬁguration screen lets you password-protect your Netopia 4741. Input your Write Access Name and Write Access Password with names or numbers totaling up to eleven digits.

Echo cancellation is set to Yes by default. With echo cancellation set to Yes, the device auto-detects whether or not the connecting device (a telephone, a modem, or a fax machine) requires echo cancellation (fax machines and modems automatically cancel echoes).

For ordinary telephone handsets, echo cancellation should be set to Yes (turned on) to eliminate echoes on the voice line. Toggling a port to No forces echo cancellation to be disabled. If you want to disable echo cancellation, toggle this item to No. You can enable or disable echo cancellation for each port on the Netopia 4741.

■ The Compression type is normally set at the voice gateway. It is visible for informational purposes, to

ascertain that the provisioning on the voice gateway is in sync with the Netopia 4741. LES stands for Loop Emulation Service, an increasingly popular standard among ATM voice gateway

manufacturers. If the voice gateway is LES-compliant, a pop-up menu allows you to choose between G711 - PCM 64K and

G726 - ADPCM 32K. Your service provider must supply you with the correct provisioning information. The reason is that in those gateway types the voice gateway expects this type of provisioning to be done prior to making any voice calls.

If the voice gateway is not LES-compliant, the pop-up menus are not available, and these ﬁelds are for information only.

Once you have made your settings for each voice port, press Escape to return to the Voice Conﬁguration menu.

■ Select Voice Coding and press Return. From the pop-up menu choose the voice coding method you will be

using. The default is mu-law, which is the standard 8-bit, 8 kHz, mono format intended primarily for the requirements of voice in North America. You can also choose a-law, a more common audio format outside North America.

■ If your service provider is using an LES-compliant voice gateway, an LES Proﬁle Number option becomes

visible. From the pop-up menu choose either Proﬁle 9 or Proﬁle 10. The Netopia 4741 currently supports LES proﬁle 9 and LES proﬁle 10. LES proﬁle 9 includes only PCM

calls. LES proﬁle 10 includes PCM and ADPCM capabilities.

Setup

■ Select Circuit Type and from the pop-up menu choose the type of circuit to which you will be connecting.

The circuit type defaults to Auto-detect. If you accept the default, the device attempts to detect the type of circuit to which you are connecting and self-conﬁgure its parameters accordingly.

If the device is unable to detect the circuit type, you can choose the type that your service provider speciifes: Multimode, T1.413, G.dmt/G.lite, or ADI.

Your service provider should supply you with the appropriate information about the type and capabilities of the access concentrator equipment they use.

■ Select Signalling Mode and from the pop-up menu choose either Echo Cancellation or the default FDM

(Frequency-Division Multiplexing). This setting must match the format used by your service provider . FDM is the most common, so you probably do not need to change it unless your provider speciﬁcally tells you to do so.

■ If you selected Multimode as the circuit type, toggle Trellis Coding Enabled to either On or Off. For any

other circuit type, this option does not appear.

Page 57

WAN and System Conﬁguration 8-3

With transmission over a noisy line, the ability to recover encoded bits is signiﬁcantly improved by using a Trellis Coder/Decoder. The Trellis Coder for ADSL can achieve a better coding gain. Trellis coding can be optionally used only for Multimode. The DSLAM and Netopia 4741 negotiate if Trellis Coding is enabled during part of their initialization.

The default is enabled, so you probably do not need to change it unless your provider speciﬁcally tells you to do so.

■ Select Cell Format and from the pop-up menu select either Scrambled (the default) or Unscrambled. This

setting must match the format used by your service provider. Scrambled is the most common, so you probably do not need to change it unless your provider speciﬁcally tells you to do so.

■ Select Unused Cell Format and from the pop-up menu select either Idle (the default) or Empty . This setting

must match the format used by your service provider. Idle is the most common, so you probably do not need to change it unless your provider speciﬁcally tells you to do so.

■ Select Data Link Encapsulation and from the pop-up menu choose your DLE. The DLE choices are PPP or

RFC 1483 (the default).

■ If you selected RFC1483, the next pop-up menu RFC1483 Mode offers the choice of Bridged 1483 or

Routed 1483. If you select Bridged 1483, a new option PPP over Ethernet (PPPoE) appears. You can then toggle PPPoE On or Off. Choosing Routed 1483 hides the PPPoE option.

■ If you selected PPP, the next pop-up menu PPP Mode offers the choice of VC Multiplexed or LLC SNAP.

■ Select Display/Change Circuit, and from the pop-up menu choose the circuit to use for this connection.

The default circuit is called Circuit 1, and uses the default values for data trafﬁc and the WAN Default Proﬁle for the connection. See “The WAN Default Proﬁle” on page 8-14 for more information.

■ Add Circuit and Delete Circuit allow you to create or delete circuit settings "on the ﬂy." This is useful if you

want to manage sets of circuit values without deleting a previous set or delete sets that no longer apply. For more information on VPIs and VCIs, see “Multiple ATM Permanent Virtual Circuit Support” below.

The Netopia 4741 supports up to eight permanent virtual circuits.

MMMMuuuullllttttiiiipppplllleeee AAAATTTTMMMM PPPPVVVVCCCC oooovvvveeeerrrrvvvviiiieeeeww

On cell-based DSL WAN interfaces, the ATM connection between the device and the central ofﬁce equipment (DSLAM) is divided logically into one or more virtual circuits (VCs). A virtual circuit may be either a permanent virtual circuit (PVC) or a switched virtual circuit (SVC). Netopia devices support PVCs.

VCs are identiﬁed by a Virtual Path Identiﬁer (VPI) and Virtual Channel Identiﬁer (VCI). A VPI is an 8-bit value between 0 and 255, inclusive, while a VCI is a 16-bit value between 0 and 65535, inclusive.

■ Circuits now support attributes in addition to their VPI and VCI values. When conﬁguring a circuit, you can

specify an optional circuit name of up to 14 characters. The circuit name is used only to identify the circuit for management purposes as a convenience to aid in selecting circuits from lists. The default circuit name is “Circuit <n>”, where <n> is some number between one and eight corresponding to the circuit’s position in the list of up to eight circuits.

■ You can also individually enable or disable a circuit without deleting it. This is useful for temporarily

Page 58

8-4 Administration Guide

removing a circuit without losing the conﬁgured attributes.

■ In order to function, each circuit must be bound to a Connection Proﬁle or to the Default Proﬁle. Among

other attributes, the proﬁle binding speciﬁes the IP addressing information for use on the circuit. Each circuit must be bound to a distinct Connection Proﬁle. You cannot bind multiple circuits to the same Connection Proﬁle.

■ Circuit Enabled allows you to enable or disable the circuit, using the Tab key. The default is enabled.

■ Trafﬁc Type allows you to select which type of trafﬁc will be routed on this circuit, Voice or Data. If you

choose Voice, the Connection Proﬁle is ﬁeld becomes unavailable and does not display.

■ Circuit VPI allows you to specify the Virtual Path Identiﬁer (VPI) value for the circuit. The default VPI value

for both ADSL and cell-based DSL is zero (0).

■ Circuit VCI allows you to specify the Virtual Channel Identiﬁer (VCI) value for the circuit. The default VCI

value depends on the type of DSLAM to which you are connecting.

■ Accessing the Connection Proﬁle Is ﬁeld in the Change Circuit menu depends not on the number of

Connection Proﬁles you have created, but the number of data VCs you have added. (See “Adding a circuit”

on page 8-7.) If you have more than one data VC you can choose how Connection Proﬁles are associated

with VCs, otherwise you get default behavior and the Connection Proﬁle Is ﬁeld cannot be selected.

Note: With multiple VCs you must explicitly statically bind the second (and all subsequent) VCs to a proﬁle. The ﬁrst VC will automatically statically bind according to pre-deﬁned dynamic binding rules when you add the second VC. It will revert back to dynamic binding if the number of VCs is reduced to one; for example, by deleting previously deﬁned VCs.

When the link comes up the device binds the VC dynamically to the ﬁrst suitable Connection Proﬁle or to the Default Proﬁle if there is no Connection Proﬁle conﬁgured.

• If you factory default the device, the VC binds to the Default Proﬁle.

• If you delete a Connection Proﬁle that is statically bound to a VC, the VC binding is set back to the Default

Proﬁle. If there is only one VC deﬁned, the VC dynamically binds to the ﬁrst suitable proﬁle or to the Default Proﬁle. If there are multiple VCs deﬁned, it binds to the Default Proﬁle.

• If you add a second VC, it is initialized to the Default Proﬁle, and the menu screens display the VC

Connection Proﬁle-related items, allowing you to bind to a speciﬁc Connection Proﬁle instead of the Default Proﬁle. In addition, the device statically binds the ﬁrst VC according to the rules used to select a proﬁle for dynamic binding. At this point, each proﬁle uses static binding when the link is brought up.

If there are no VCs when you add a VC -- for example, if you deleted all your previous VCs and started adding them again -- dynamic binding will occur when the link comes up. If you delete a VC, leaving only one VC, that VC resumes dynamically binding again.

The ﬁelds in the Add Circuit screen are the similar to the ﬁelds in the Change Circuit screen described above. You can add up to seven circuits (for a total of eight) and bind them to separate Connection Proﬁles.

■ Use Connection Proﬁle and Use Default Proﬁle for Circuit allow you to choose the proﬁle that you want to

associate with that circuit. Choosing Use Connection Proﬁle presents a pop-up menu that lists all of your enabled Connection Proﬁles. Choosing a proﬁle from the list statically binds the circuit to the selected proﬁle. Choosing Use Default Proﬁle for Circuit statically binds the circuit to the Default Proﬁle. When the circuit is bound to a Connection Proﬁle, Use Connection Proﬁle displays the name of the proﬁle; when the circuit is associated with the Default Proﬁle, Use Connection Proﬁle displays Default Proﬁle.

When more than one circuit is enabled, you must explicitly statically bind each circuit to the Connection Proﬁle to be used on the circuit, or to the Default Proﬁle. To do this you use Use Connection Proﬁle or Use Default Proﬁle for Circuit.

Creating a New Connection Proﬁle

For a Netopia 4741, connection proﬁles are useful for conﬁguring the connection and authentication settings for negotiating a PPP connection on the DSL link. If you are using the PPP data link encapsulation method, you can store your authentication information in the connection proﬁle so that your user name and password (or host name and secret) are transmitted when you attempt to connect.

Connection proﬁles deﬁne the networking protocols necessary for the device to make a remote connection. A connection proﬁle is like an address book entry describing how the device is to get to a remote site, or how to recognize and authenticate a connection. To create a new connection proﬁle, you navigate to the WAN Conﬁguration screen from the Main Menu, and select Add Connection Proﬁle.

7. Toggle or enter the IP Parameters you require.

■ The Netopia 4741 allows a central site router to supply an entire IP subnet, rather than a single IP

address. If the applicable Connection Proﬁle speciﬁes an unnumbered, non-NAT connection and Negotiate LAN IP Addr/Mask is set to On, PPP will attempt to negotiate both an IP Address and subnet

mask. Once the router has reconﬁgured the address serving pool only to conform to the negotiated subnet,

you can adjust the base or extent of the pool and reboot the router. Your adjustments will not be overwritten when the connection is next renegotiated because the router only reconﬁgures the address serving pool if it lies outside the negotiated subnet.

The router does not adjust any address serving parameters other than the base and extent of the address serving pool. This allows you to otherwise conﬁgure address serving as you please using the normal address serving conﬁguration items. For example, if you disable address serving, the router will not enable address serving when it reconﬁgures the address serving pool.

■ This toggle is visible only if the proﬁle’s Data Link Encapsulation is set to PPP, the Address Translation

Enabled toggle is set to No and IP Addressing is set to Unnumbered. The default value is No.

■ RIP Proﬁle Options is not visible if Negotiate LAN IP Addr/Mask is set to Yes and the Remote IP Mask

System Conﬁguration Screens

You can connect to the Netopia 4741’s system conﬁguration screens in either of two ways:

■ By using Telnet with the device’s Ethernet port IP address

■ Through the console port, using a local terminal (see “Connecting a Console Cable to Your Device” on

page 5-3)

You can also retrieve the Netopia 4741’s conﬁguration information and remotely set its parameters using the Simple Network Management Protocol (see “SNMP” on page 13-13).

Open a Telnet connection to the device’s IP address; for example, “192.168.1.1.” The console screen will open to the Main Menu, similar to the screen shown below:

System Conﬁguration Features

The Netopia 4741 ADSL Integrated Access Device’s default settings may be all you need to conﬁgure your Netopia 4741. Some users, however, require advanced settings or prefer manual control over the default selections. For these users, the Netopia 4741 provides system conﬁguration options.

To help you determine whether you need to use the system conﬁguration options, review the following requirements. If you have one or more of these needs, use the system conﬁguration options described in later chapters.

■ System conﬁguration of dynamic IP address distribution through DHCP or BootP

■ Greater network security through the use of ﬁlters

■ System conﬁguration of connection proﬁles

System Date Format: MM/DD/YY

System Time Format: AM/PM

The Netopia 4741 uses Network Time Protocol (NTP) by default to set the date and time automatically. You may want to modify the default settings for your own environment.

NTP takes effect ﬁve minutes after the device boots. At that time NTP attempts to connect to a central Time Server and set the device’s clock. If the device is rebooted for any reason, the time settings revert to an internal default date and time for ﬁve minutes until NTP can reconnect to its time server and reset the clock.

Page 78

8-24 Administration Guide

You should pick a time server close to your location, if possible. Lists of public time servers supported by corporations, governments, and educational institutions are available by searching the Internet.

■ Enter a Time Server Host Name or IP Address. This may be in the form hostname.domainname or in

dotted quad (xxx.xxx.xxx.xxx) notation. The default address 204.152.184.72 is a public NTP server and may be suitable for your needs, or you can supply your own choice.

■ From the pop-up Time Zone menu, select your time zone.

■ Set the NTP Update Interval to some convenient interval such as every day (24:00) or every few hours.

■ From the pop-up System Date Format menu select the date format used in your region: MM/DD/YY,

DD/MM/YY, or YY/MM/DD.

■ From the pop-up System Time Format menu select your preferred time notation: AM/PM or 24hr.

If you do not want to use NTP for date and time setting, you can toggle it to Off. In that case, you can set the clock manually (Remember that the clock reverts to a default date and time any time the device is rebooted, so you must reset the clock manually.):

■ From the pop-up System Date Format menu select the date format used in your region: MM/DD/YY,

DD/MM/YY, or YY/MM/DD.

■ Enter the Current Date in whatever format you have chosen.

■ From the pop-up System Time Format menu select your preferred time notation: AM/PM or 24hr.

■ Enter the Current Time in whatever format you have chosen.

■ From the AM or PM pop-up menu, select AM or PM.

The Netopia 4741 uses Internet Protocol (IP) to communicate both locally and with remote networks. This chapter shows you how to conﬁgure the router to route IP trafﬁc. You also learn how to conﬁgure the router to serve IP addresses to hosts on your local network.

Netopia’s IP routing features Network Address Translation, Virtual Private Networking (VPNs), and IP address serving.

This section covers the following topics:

■ “IP Setup” on page 9-2

■ “IP Address Serving” on page 9-10

■ “More Address Serving Options” on page 9-17

■ “DHCP Relay Agent” on page 9-23

■ “Connection Proﬁles” on page 9-25

Network Address Translation allows communication between the LAN connected to the Netopia 4741 and the Internet using a single (or a few) IP address(es) instead of a routed account with separate IP addresses for each computer on the network.

Network Address Translation also provides increased security by hiding the local IP addresses of the LAN connected to the Netopia 4741 from the outside world.

The setup is simpler, so ISPs typically offer Internet accounts supporting Network Address Translation at a signiﬁcant cost savings.

For a detailed discussion of Network Address Translation, see Chapter 10, “Multiple Network Address

Translation.”

IP Setup

The IP Setup options screen is where you conﬁgure the Ethernet side of the Netopia 4741. The information you enter here controls how the router routes IP trafﬁc.

Consult your network administrator or ISP to obtain the IP setup information (such as the Ethernet IP address, Ethernet subnet mask, default IP gateway, and Primary Domain Name Server IP address) you will need before changing any of the settings in this screen. Changes to these settings that you make in this screen will take effect only after the Netopia 4741 is reset.

To go to the IP Setup options screen, from the Main Menu, select System Conﬁguration, then IP Setup. The IP Setup screen appears.

IP Setup Ethernet IP Address: 192.128.117.162

Ethernet Subnet Mask: 255.255.255.0 Define Additional Subnets...

Receive RIP... Both Transmit RIP... Off

Static Routes... IP Address Serving... Network Address Translation (NAT)...

Set up the basic IP attributes of your Netopia in this screen.

Follow these steps to conﬁgure IP setup for your Netopia 4741:

■ Select Ethernet IP Address and enter the IP address for the Netopia 4741’s Ethernet port.

■ Select Ethernet Subnet Mask and enter the subnet mask for the Ethernet IP address that you entered in

the last step.

■ If you desire multiple subnets select Deﬁne Additional Subnets. If you select this item you will be taken to

the IP Subnets screen. This screen allows you to deﬁne IP addresses and masks for additional subnets. See “IP subnets” on page 9-4 for details.

Page 85

IP Setup 9-3

The Netopia 4741 ADSL Integrated Access Device supports multiple IP subnets on the Ethernet interface. You may want to conﬁgure multiple IP subnets to service more hosts than are possible with your primary subnet. It is not always possible to obtain a larger subnet from your ISP. For example, if you already have a full Class C subnet, your only option is multiple Class C subnets, since it is virtually impossible to justify a Class A or Class B assignment.

If you are using NAT, you can use the reserved Class A or Class B subnet.

■ Select Default IP Gateway and enter the IP address for a default gateway. This can be the address of any

major router accessible to the Netopia 4741. A default gateway should be able to successfully route packets when the Netopia 4741 cannot recognize

the intended recipient’s IP address. A typical example of a default gateway is the ISP’s router.

■ Select Primary Domain Name Server and enter the IP address for a domain name server. The domain

name server matches the alphabetic addresses favored by people (for example, robin.hood.com) to the IP addresses actually used by IP routers (for example, 163.7.8.202).

■ If a secondary DNS server is available, select Secondary Domain Name Server and enter its IP address.

The secondary DNS server is used by the Netopia 4741 when the primary DNS server is inaccessible. Entering a secondary DNS is useful but not necessary.

■ Select Domain Name and enter your network’s domain name (for example, netopia.com). Netopia strongly

recommends that you enter a domain name.

■ Routing Information Protocol (RIP) is needed if there are IP routers on other segments of your Ethernet

network that the Netopia 4741 needs to recognize. If this is the case select Receive RIP and select v1, v2, or Both from the pop-up menu. With Receive RIP set to v1, the Netopia 4741’s Ethernet port will

accept routing information provided by RIP packets from other routers that use the same subnet mask. Set to v2, the Netopia 4741 will accept routing information provided by RIP packets from other routers that use different subnet masks. Set to Both, the Netopia 4741 will accept information from either RIP v1 or v2 routers.

■ If you want the Netopia 4741 to advertise its routing table to other routers via RIP , select T ransmit RIP and

select v1, v2 (broadcast), or v2 (multicast) from the pop-up menu. With Transmit RIP v1 selected, the Netopia 4741 will generate RIP packets only to other RIP v1 routers. With Transmit RIP v2 (broadcast) selected, the Netopia 4741 will generate RIP packets to all other hosts on the network. With Transmit RIP v2 (multicast) selected, the Netopia 4741 will generate RIP packets only to other routers capable of recognizing RIP v2 packets.

■ Select Static Routes to manually conﬁgure IP routes. See the section “Static routes,” below.

■ Select Network Address Translation to conﬁgure advanced MultiNAT features. See “Multiple Network

Address Translation” on page 10-1.

■ If you select IP Address Serving you will be taken to the IP Address Serving screen (see “IP Address

Serving” on page 9-10). Since no two hosts can use the same IP address at the same time, make sure

that the addresses distributed by the Netopia 4741 and those that are manually conﬁgured are not the same. Each method of distribution must have its own exclusive range of addresses to draw from.

■ If you select Filter Sets you will be taken directly to the screen for conﬁguring IP packet ﬁlters. For

information see “About Filters and Filter Sets,” beginning on page 12-4.

9-4 Administration Guide

IP subnets

The IP Subnets screen allows you to conﬁgure up to eight Ethernet IP subnets on unlimited-user models, one “primary” subnet and up to seven secondary subnets, by entering IP address/subnet mask pairs:

IP Subnets

IP Address Subnet Mask

---------------- -------------- #1: 192.128.117.162 255.255.255.0

#2: 0.0.0.0 0.0.0.0 #3: #4: #5: #6: #7: #8:

Note: You need not use this screen if you have only a single Ethernet IP subnet. In that case, you can continue to enter or edit the IP address and subnet mask for the single subnet on the IP Setup screen.

This screen displays up to eight rows of two editable columns, preceded by a row number between one and eight. If you have eight subnets conﬁgured, there will be eight rows on this screen. Otherwise, there will be one more row than the number of conﬁgured subnets. The last row will have the value 0.0.0.0 in both the IP address and subnet mask ﬁelds to indicate that you can edit the values in this row to conﬁgure an additional subnet. All eight row labels are always visible, regardless of the number of subnets conﬁgured.

■ To add an IP subnet, enter the Netopia 4741’s IP address on the subnet in the IP Address ﬁeld in a

particular row and the subnet mask for the subnet in the Subnet Mask ﬁeld in that row.

IP Setup 9-5

■ T o delete a conﬁgured subnet, set both the IP address and subnet mask values to 0.0.0.0, either explicitly

or by clearing each ﬁeld and pressing Return to commit the change. When a conﬁgured subnet is deleted, the values in subsequent rows adjust up to ﬁll the vacant ﬁelds.

The subnets conﬁgured on this screen are tied to the address serving pools conﬁgured on the IP Address Pools screen, and changes on this screen may affect the IP Address Pools screen. In particular, deleting a subnet conﬁgured on this screen will delete the corresponding address serving pool, if any, on the IP Address Pools screen.

Conﬁguration.... If you select Subnet Conﬁguration, you will return to the IP Subnets screen that allows you to

deﬁne IP addresses and masks for additional Ethernet IP subnets.

Static routes

Static routes are IP routes that are maintained manually. Each static route acts as a pointer that tells the Netopia 4741 how to reach a particular network. However, static routes are used only if they appear in the IP routing table, which contains all of the routes used by the Netopia 4741 (see “IP Routing T able” on page 13-9).

Static routes are helpful in situations where a route to a network must be used and other means of ﬁnding the route are unavailable. For example, static routes are useful when you cannot rely on RIP.

To go to the Static Routes screen, select Static Routes in the IP Setup screen and press Return.

information; Low means that the RIP information takes precedence over the static route.

■ If the static route conﬂicts with a connection proﬁle, the connection proﬁle will always take precedence.

■ To make sure that the static route is known only to the Netopia 4741, select Advertise Route Via RIP and

toggle it to No. To allow other RIP-capable routers to know about the static route, select Advertise Route Via RIP and toggle it to Yes. When Advertise Route Via RIP is toggled to Yes, a new item called RIP Metric

appears below Advertise Route Via RIP. With RIP Metric you set the number of routers, from 1 to 15, between the sending router and the

destination router. The maximum number of routers on a packet’s route is 15. Setting RIP Metric to 1 means that a route can involve 15 routers, while setting it to 15 means a route can only involve one router.

■ Select ADD STA TIC ROUTE NOW to save the new static route, or select CANCEL to discard it and return to

the Static Routes screen.

■ Up to 32 static routes can be created, but one is always reserved for the default gateway, which is

conﬁgured using either Easy Setup or the IP Setup screen in system conﬁguration.

Modifying a static route

To modify a static route, in the Static Routes screen select Display/Change Static Route to display a table of static routes.

Select a static route from the table and go to the Change Static Route screen. The parameters in this screen are the same as the ones in the Add Static Route screen (see “Adding a static route” on page 9-8).

Deleting a static route

To delete a static route, in the Static Routes screen select Delete Static Route to display a table of static routes. Select a static route from the table and press Return to delete it. To exit the table without deleting the selected static route, press Escape.

Rules of static route installation

The Netopia 4741 applies certain rules before installing enabled static routes in the IP routing table. An enabled static route will not be installed in the IP routing table if any of the following conditions are true:

■ The static route’s Next Gateway IP Address matches an IP address in the range of IP addresses being

distributed by DHCP.

■ The static route’s Next Gateway IP Address is determined to be unreachable by the Netopia 4741.

■ The static route’s route information conﬂicts with a connection proﬁle’s route information.

■ The connection proﬁle associated with the static route has a disabled dial-on-demand setting, and there is

no current connection using that connection proﬁle.

A static route that is already installed in the IP routing table will be removed if any of the conditions listed above become true for that static route. However, an enabled static route is automatically reinstalled once the conditions listed above are no longer true for that static route.

Serving

• Serve DHCP Clients

• Serve BootP Clients

• Serve Dynamic WAN Clients

In addition to being a router, the Netopia 4741 is also an IP address server. There are three protocols it can use to distribute IP addresses.

■ The ﬁrst, called Dynamic Host Conﬁguration Protocol (DHCP), is widely supported on PC networks, as well

as Apple Macintosh computers using Open Transport and computers using the UNIX operating system. Addresses assigned via DHCP are “leased” or allocated for a short period of time; if a lease is not renewed, the address becomes available for use by another computer. DHCP also allows most of the IP parameters for a computer to be conﬁgured by the DHCP server, simplifying setup of each machine.

■ The second, called BootP (also known as Bootstrap Protocol), is the predecessor to DHCP and allows older

IP hosts to obtain most of the information that a DHCP client would obtain. However, in contrast, BootP address assignments are “permanent” since there is no lease renewal mechanism in BootP.

■ The third protocol, called Dynamic WAN, is part of the PPP/MP suite of wide area protocols used for WAN

connections. It allows remote terminal adapters and NAT-enabled routers to be assigned a temporary IP address for the duration of their connection.

Since no two hosts can use the same IP address at the same time, make sure that the addresses distributed by the Netopia 4741 and those that are manually conﬁgured are not the same. Each method of distribution must have its own exclusive range of addresses to draw from.

Go to the System Conﬁguration screen. Select IP Address Serving and press Return. The IP Address Serving screen will appear.

Follow these steps to conﬁgure IP Address Serving:

■ If you enabled IP Address Serving, then DHCP, BootP clients and Dynamic WAN clients are automatically

enabled.

■ The IP Address Serving Mode pop-up menu allows you to choose the way in which the Netopia 4741 will

serve IP addresses. The device can act as either a DHCP Server or a DHCP Relay Agent. (See “DHCP Relay

Agent” on page 9-23 for more information.) In most cases, you will use the device to serve its own pool of

IP addresses, hence DHCP Server is the default. Address serving can also be disabled.

■ Select Number of Client IP Addresses and enter the total number of contiguous IP addresses that the

Netopia 4741 will distribute to the client machines on your local area network.

■ Select 1st Client Address and enter the ﬁrst client IP address that you will allocate to your ﬁrst client

machine. For instance, on your local area network you may want to ﬁrst ﬁgure out which machines are going to be allocated speciﬁc static IP addresses so that you can determine the pool of IP addresses that you will be serving addresses from via DHCP, BootP, and/or Dynamic WAN.

Example: Your ISP has given your Netopia 4741 the IP address 192.168.6.137, with a subnet mask of

255.255.255.248. The subnet mask allocated will give you six IP addresses to use when connecting to the ISP over the Internet (for more information on IP addressing refer to Appendix B, “Understanding IP

Addressing.”). Your address range will be from .137-.142. In this example you would enter 192.168.6.138

as the 1st Client Address, since the router itself must have an IP address.

■ To enable DHCP, select Serve DHCP Clients and toggle it to Yes. DHCP serving is automatic when IP

Address Serving is enabled.

■ The default DHCP Lease time is one hour. This may be unnecessarily brief in your network environment.

Consequently, the DHCP lease time is now conﬁgurable. The DHCP Lease Time (Hours) setting allows you to modify the router’s default lease time of one hour. You can enter any number up to and including 168 hours (one week) for the DHCP lease.

If you have conﬁgured multiple Ethernet IP subnets, the appearance of the IP Address Serving screen is altered slightly:

Configure Address Pools... Serve DHCP Clients: Yes

DHCP NetBios Options... Serve BOOTP Clients: Yes Serve Dynamic WAN Clients: Yes

The ﬁrst three menu items are hidden, and Conﬁgure Address Pools... appears instead. If you select Conﬁgure Address Pools... you will be taken to the IP Address Pools screen that allows you to conﬁgure an address

serving pool for each of the conﬁgured Ethernet IP subnets. See “IP Address Pools” on page 9-13.

Page 95

IP Setup 9-13

IP Address Pools

The IP Address Pools screen allows you to conﬁgure a separate IP address serving pool for each of up to eight conﬁgured Ethernet IP subnets:

IP Address Pools

Subnet (# host addrs) 1st Client Addr Clients Client Gateway

--------------------- --------------- ------- --------------

192.128.117.0 (253) 192.128.117.196 16 192.128.117.162

192.129.117.0 (253) 192.129.117.110 8 192.129.117.4

This screen consists of between two and eight rows of four columns each. There are exactly as many rows as there are Ethernet IP subnets conﬁgured on the IP Subnets screen.

■ The Subnet (# host addrs) column is non-selectable and non-editable. It indicates the network address of

the Ethernet IP subnet for which an address pool is being conﬁgured and the number of host addresses available on the subnet. The network address is equal to the router’s IP address on the subnet bitwise-ANDed with the subnet mask. The host address count is equal to the subnet size minus three, since one address is reserved for the network address, one for the subnet broadcast address, and one for the router’s interface address on the subnet.

You can edit the remaining columns in each row.

■ The 1st Client Addr and Clients columns allow you to specify the base and extent of the address serving

pool for a particular subnet. Entering 0.0.0.0 for the ﬁrst client address or 0 for the number of clients indicates that no addresses will be served from the corresponding Ethernet IP subnet.

■ The Client Gateway column allows you to specify the default gateway address that will be provided to

clients served an address from the corresponding pool. The value defaults to the Netopia 4741’s IP address on the corresponding subnet (or the Netopia 4741’s default gateway, if that gateway is located on the subnet in question). You can override the value by entering any address that is part of the subnet.

DHCP, BootP, and dynamic WAN clients may receive an address from any one of the address serving pools conﬁgured on this screen.

9-14 Administration Guide

Numerous factors inﬂuence the choice of served address. It is difﬁcult to specify the address that will be served to a particular client in all circumstances. However, when the address server has been conﬁgured, and the clients involved have no prior address serving interactions, the Netopia 4741 will generally serve the ﬁrst unused address from the ﬁrst address pool with an available address. The Netopia 4741 starts from the pool on the ﬁrst row and continues to the pool on the last row of this screen.

Once the address server and/or the clients have participated in address serving transactions, different rules apply:

■ When requesting an address, a client will often suggest an address to be assigned, such as the one it was

last served. The Netopia 4741 will attempt to honor this request if the address is available. The client stores this address in non-volatile storage, for example, on disk, and the speciﬁc storage method/location differs depending on the client operating system.

■ When requesting an address, a client may provide a client identiﬁer, or, if it does not, the Netopia 4741

may construct a pseudo-client identiﬁer for the client. When the client subsequently requests an address, the Netopia 4741 will attempt to serve the address previously associated with the pseudo-client identiﬁer. This is normally the last address served to the client.

■ Otherwise, the Netopia will select the least-recently used available address, starting from the ﬁrst address

in the ﬁrst pool and ending with the last address in the last pool.

Note: The address serving pools on this screen are tied to the IP subnets conﬁgured on the IP Subnets screen. Changes to the IP Subnets screen may affect this screen. In particular, deleting a subnet on the IP Subnets screen will delete the corresponding address serving pool, if any, on this screen.

DHCP NetBIOS Options

If your network uses NetBIOS, you can enable the Netopia 4741 to use DHCP to distribute NetBIOS information. NetBIOS stands for Network Basic Input/Output System. It is a layer of software originally developed by IBM

and Sytek to link a network operating system with speciﬁc hardware. NetBIOS has been adopted as an industry standard. It offers LAN applications a variety of “hooks” to carry out inter-application communications and data transfer. Essentially, NetBIOS is a way for application programs to talk to the network. To run an application that works with NetBIOS, a non-IBM network operating system or network interface card must offer a NetBIOS emulator. Many vendors either provide a version of NetBIOS to interface with their hardware or emulate its transport layer communications services in their network products. A NetBIOS emulator is a program provided by NetWare clients that allow workstations to run applications that support IBM’s NetBIOS calls.

■ Select DHCP NetBios Options and press Return. The DHCP NetBIOS Options screen appears.

More Address Serving Options

The Netopia 4741 includes a number of enhancements in the built-in DHCP IP address server. These enhancements include:

■ The ability to exclude one or more IP addresses from the address serving pool so the addresses will not be

served to clients.

■ The ability to reserve a particular IP address for a client with a particular Ethernet MAC address.

■ The ability to view the host name associated with a client to which the router has leased an IP address.

■ The ability for the router’s Ethernet IP address(es) to overlap the DHCP address serving pool(s).

■ The ability to serve as a DHCP Relay Agent.

The Netopia 4741 supports reserving an IP address only for a type 1 client identiﬁer (i.e., an Ethernet hardware address). It does not support reserving an IP address for an arbitrary client identiﬁer. (For more information on client identiﬁers, see RFC 2131, section 9.14.)

The rightmost column displays the host name supplied by the client if one was provided; otherwise it displays the client identiﬁer. (If a host name is displayed, the client identiﬁer is still accessible in a Details pop-up menu. See below.)

Note: The server does not query the client for its host name. Macintosh computers running versions of MacOS prior to MacOS version 8.5 (OT 2.0.1, TCP/IP 2.0.1) do not supply a host name option in their DHCP messages, so no host name will appear in the Served IP Addresses list.
