Ofﬁce telephone systems are commonly one of two types, PBX (Private Branch Exchange) or Centrex (Central Ofﬁce Exchange). Technically, Centrex is a subset of PBX.

PBX users share a certain number of outside lines for making telephone calls external to the PBX. Most medium-sized and larger companies use a PBX because it's much less expensive than connecting an external telephone line to every telephone in the organization. In addition, it's easier to call someone within a PBX because the number you need to dial is typically just 3 or 4 digits.

Centrex is a newer variation on the PBX. It is a PBX with all switching occurring at a local telephone of ﬁce instead of at the company's premises. Typically, the telephone company owns and manages all the communications equipment necessary to implement the PBX and then sells various services to the company.

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 Symmetric (same speed upload and download) DSL for IP connectivity and a PBX 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 voice switch is called a Voice Gateway and the data switch is called a Digital Subscriber Line Access Multiplexer (DSLAM) or access concentrator. Both the voice and data signals are concentrated at the DSLAM and forwarded either to a data router or to the Voice Gateway. Both kinds of switches are manufactured by a variety of companies. The IAD must be capable of communicating with a wide array of possible combinations of Voice Gateways and DSLAMs.

1-2 Administration Guide

An IAD combines the voice telephony features of a telephone PBX 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 carr y all of these services over a single existing copper telephone line by using the different frequency ranges available on the copper wire for voice and data trafﬁc.

The Netopia 4753 G.SHDSL Integrated Access Device is that device: a Centrex-based PBX system combined with an SHDSL internet router.

The Netopia 4753 G.SHDSL Integrated Access Device provides the following features:

Support for ordinary analog phone equipment.

Works with the same FXS analog phone sets and key systems

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

Centrex support.

Advanced telephone features enabled by your service provider's telephone switch such as

call forwarding or conferencing operate exactly as they did before.

Netopia data routing engine.

Provides the same advanced, business-class data routing features used by leading DSL service providers around the world.

G.SHDSL.

provided by the telephone company. G.SHDSL negotiates the highest achievable data rate given the loop conditions and will allow you to connect to the Internet at a minimum of 128Kbps bi-directional, up to 2.320 Mbps. Your LAN will constantly be connected and you will not have to dial into the Internet. G.SHDSL uses more of the bandwidth on copper phone lines than what is currently used for plain old telephone ser vice (POTS). By using frequencies between 26 kHz and 1MHz, G.SHDSL can encode more data to achieve higher data rates than would otherwise be possible in the restricted frequency range of a POTS network (up to 4 kHz). In order to use the frequencies above the voice audio spectrum, DSL equipment must be installed on both ends.

Finding an Internet Service Provider

The Netopia 4753 G.SHDSL Integrated Access Device provides its high speed symmetric (two-way) digital connection to the Internet through a Competitive Local Exchange Carrier (CLEC) -- a type of mini phone company. The CLEC uses a compatible type of switching equipment known as a Digital Subscriber Line Access Multiplexer (DSLAM). The DSLAM that you connect to with your Netopia Router must be capable of handling these symmetric connections. The Netopia 4753 is certiﬁed for use with DSLAMs manufactured by Nokia , Lucent, Paradyne, Nortel networks, and Copper Mountain.

If you have purchased your Netopia Router through a Netopia ISP par tner, you can be sure that an account that supports G.SHDSL connections will be available.

If your area has more than one ISP, the following considerations will help you decide which ISP is best suited for your requirements.

In determining which Internet ser vice provider (ISP) to establish your account with, make sure that your ISP supports connections via a CLEC that also supports voice ser vices.

Use an ISP that provides Internet access through a G.SHDSL Digital Subscriber Line and that suppor ts the Netopia 4753 G.SHDSL Integrated Access Device. If you would like to use an ISP that you already have a relationship with but that is not familiar with the Netopia 4753, call us at 1-800-NETOPIA. Our representative can call your ISP and introduce them to the product. If necessar y, we will provide them with the technical background they need to support the product.

Unique requirements

Make sure the ISP can meet any unique requirements you may have, such as:

■

Dynamic or static IP addressing

Class C IP address

■

Custom domain name

■

Multiple e-mail addresses

Web site hosting

■

Pricing and support

Compare pricing, service, and technical suppor t ser vice among various ISPs.

Endorsements

Consider recommendations from colleagues and reviews in publications. Netopia lists Netopia Cer tiﬁed ISPs on our Web site at

http://www.netopia.com

Deciding on an ISP Account

Your ISP may offer various Internet access account plans. Typically, these plans vary by usage charges and the number of host IP addresses supplied. Evaluate your networking needs and discuss them with your ISP before deciding on a plan for your network.

Setting Up Internet Services 2-3

Setting up a Netopia 4753 account

Check whether your ISP has the Netopia 4753 on its list of supported products that have been tested with a particular conﬁguration. If the ISP does not have the Netopia 4753 on such a list, describe the Netopia 4753 in as much detail as needed, so your ISP account can be optimized. As appropriate, refer your ISP to Netopia’s Web site www.netopia.com for more information.

Obtaining an IP address

Typically, each network computer that requires Internet access requires its own unique IP address. If some or all network computers require simultaneous Internet access, obtain a block of IP host addresses large enough for each computer to have its own address, plus one for the Netopia 4753.

Consider expected growth in your network when deciding on the number of addresses to obtain. Alternatively, you can use the Network Address Translation feature of SmartIP.

SmartIP

The Netopia 4753 G.SHDSL Integrated Access Device supports Multiple Network Address Translation (MultiNAT).

Network Address Translation provides Internet access to the network connected to the Netopia 4753 using only a single IP address. These routers translate between the internal or local area network (LAN) addresses and a single external IP address, and route accordingly.

For more information on Network Address Translation, see Chapter 11, “Multiple Network Address Translation.”

Obtaining Information from the ISP

After your account is set up, the ISP should send you the IP parameter information that will help you conﬁgure the Netopia 4753.

Local LAN IP address information to obtain

Your ISP will need to provide you with the following information:

The default gateway IP address (same as remote IP address in most cases)

■

Local WAN IP address and subnet mask

■

Primary and secondary domain name ser ver (DNS) IP addresses

Domain name (usually the same as the ISP’s domain name unless you have registered for your own

■

individual domain name)

Note:

The default gateway, WAN address and mask, DNS, and domain name are all obtainable via WAN DHCP, if your ISP supports it.

With Network Address Translation

If you are using MultiNAT, you should obtain the following:

If you are connecting to a remote site using Network Address Translation on your router, your provider will

■

2-4 Administration Guide

not deﬁne the IP address information on your local LAN. You can deﬁne this information based on an IP conﬁguration that may already be in place for the existing network. Alternatively, you can use the default IP address range used by the router.

Without Network Address Translation

If you are not using Network Address Translation, you will need to obtain all of the local LAN IP address information from your ISP.

If you are not using SmartIP (NAT), you should obtain:

The number of Ethernet IP host addresses available with your account and the ﬁrst usable IP host address

Sharing the Connection 4-5

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 4753 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 4753 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-par ty 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 4753.

4-6 Administration Guide

Static conﬁguration (optional)

If you are manually conﬁguring for a ﬁxed or static IP address, perform the following:

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

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

Or, in the MacTCP window, select Ethernet and click the More button.

Readying Computers on Your Local Network

PC and Macintosh computers must have certain components installed before they can communicate through the Netopia 4753. 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 4753

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 4753. 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 4-2. Macintosh computers use either MacTCP or Open Transport. See “Conﬁguring TCP/IP on Macintosh Computers” on page 4-5.

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

Once the Netopia 4753 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 4753 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 por t on the back of the router. For more information on attaching the console cable, see “Connecting a Console Cable to Your Device” on page 6-3.

■ 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 Telnet application or simply run Telnet

Console-Based Management 6-3

from the Start menu.

■ If you connect a Macintosh computer, you can use the NCSA Telnet program supplied on the Netopia 4753

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 4753 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 or MacOSX, included on the Netopia CD, for Macintosh computers.

The Netopia 4753 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 por t is called the Modem port or Printer port.) This connection lets you use the computer to conﬁgure and monitor the Netopia 4753 via the console screens.

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 can enter another speciﬁc address if you want to use static addressing. In that case, enter the local WAN address your ISP gave you. Press Return.

3. If you selected PPP data link encapsulation in the DSL Line Conﬁguration screen, a PPP Authentication menu item appears. The authentication protocol and user name/password combinations you enter must be assigned or agreed to in advance between you and your ISP. Select PPP Authentication and press Return.

From the pop-up menu that appears, select the authentication method your ISP uses: PAP (Password Authentication Protocol), CHAP (Challenge Handshake Authentication Protocol), or None.

■ PAP is the most common, and requires you to enter a User Name and Password in the next two ﬁelds.

■ CHAP requires you to enter a Host Name and Secret in the next two ﬁelds.

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 reser ved 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 11-1 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. 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 4753’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 ser ver 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.

This chapter describes the telephony services and conﬁguration of the Netopia 4753 G.SHDSL Integrated Access Device. For speciﬁc details on conﬁguration and use of the Netopia 4753’s Internet connection, refer to

Chapter 7, “Easy Setup” and Chapter 9, “WAN and System Conﬁguration.”

This chapter covers the following topics:

■ “Introduction” on page 8-1

■ “Conﬁguring the Voice Features” on page 8-2

IIIInnnnttttrrrroooodddduuuuccccttttiiiioooonn

The Netopia 4753 provides small and medium sized businesses with a complete Centrex PBX system. It supports voice call switching between the SDSL link and eight local extensions. Call management features can include distinctive ringing, intelligent call forwarding, Direct Inward Dial (DID), Caller ID, and hunt groups. Important key system features such as call hold, call transfer, and call waiting are all supported.

Note: Since the Netopia 4753 is a Centrex-based IAD, speciﬁc voice features available to you via the Netopia 4753 will depend on the services for which you contract with your service provider.

The Netopia 4753 supports up to eight telephone extensions and up to eight derived voice lines. Like the rest of the 4700-series line, the Netopia 4753 includes the Netopia data routing engine for any number of attached computers or other network devices connected to a single 10/100 Ethernet port.

Key features include:

■ Fax/Modem: Conﬁgurable Voice port for incoming fax or modem calls. This is another term for echo

cancellation support.

■ Voice Gateway Interoperability: CopperCom, JetStream, Tollbridge TDSoft, Zhone. General Bandwidth

support to follow in an upcoming ﬁrmware release.

Centrex is a simpler variation on the PBX. It is a PBX with all switching occurring at a local telephone of ﬁce instead of at the company's premises. Typically, the telephone company owns and manages all the communications equipment necessary to implement the PBX and then sells various services to the company.

EEEExxxxppppllllaaaannnnaaaattttiiiioooonnnn ooooffff tttteeeerrrrmmmmss

Some telephony terms mean different things in Centrex mode and PBX/local switching mode: Toll Restriction, Speed Dial, and Distinctive Ringing. The Netopia 4753 operates in Centrex mode.

■ Toll Restriction Operation - Centrex Mode: When you pick up the phone, you receive a dial tone from the

central ofﬁce. When 9 is pressed, the Netopia 4753 detects 9 and returns a busy tone (locally generated). Incoming calls are allowed. This allows local extension calling through the central ofﬁce, but not long

distance or local calls.

Toll Restriction Operation - PBX/Local Switching Mode: When you pick up the phone, you receive local PBX dial tone. When a 9 (or outside line code) is pressed, the IAD detects the digit and returns busy (locally generated). Incoming calls are allowed. Extension calls (locally switched) are allowed.

■ Speed Dial - Centrex Mode: In Centrex Mode, when you pick up the phone, dial-tone from the central ofﬁce

is present. It is therefore, not possible to program the phone or use speed dial in this mode from the phone.

Speed Dial - PBX/Local Switching mode: In this mode, you have the ability to pick up the phone, receive local dial tone and proceed to program the phone w/ local speed dial options. In addition, taking the phone off hook and pressing speed dial numbers will cause the stored speed dial digits to be sent out. This is independent of the previous mode.

8-4 Administration Guide

Echo cancellation is set to Yes by default. For ordinar y telephone handsets, echo cancellation should be set to Yes (turned on) to eliminate echoes on the voice line. Toggling a port to No allows you to connect a fax machine or modem to the phone port (since fax machines and modems automatically cancel echoes). 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 4753.

■ 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 4753.

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, the LES Proﬁle Number option becomes

visible. From the pop-up menu choose either Proﬁle 9 or Proﬁle 10.

The Netopia 4753 currently suppor ts LES proﬁle 9 and LES proﬁle 10. LES proﬁle 9 includes only PCM calls. LES proﬁle 10 includes PCM and ADPCM capabilities.

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 vir tual circuit may be either a permanent virtual circuit (PVC) or a switched vir tual circuit (SVC). Netopia devices support PVCs.

VCs are identiﬁed by a Virtual Path Identiﬁer (VPI) and Vir tual 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

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 9-7.) 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 star ted 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.

Creating a New Connection Proﬁle

For a Netopia 4753, 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 necessar y for the device to make a remote connection. A connection proﬁle is like an address book entr y 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.

The WAN Default Proﬁle

If you are using RFC1483 datalink encapsulation, the WAN Default Proﬁle screen controls whether or not the DSL link will come up without an explicitly conﬁgured connection proﬁle. (PPP datalink encapsulation does not support a default proﬁle, and the corresponding menu item is unavailable.) See “Creating a New Connection

Proﬁle” on page 9-10 for more information.

You access the Default Proﬁle screen from the Main Menu by selecting WAN Conﬁguration and then selecting Default Proﬁle.

System Date Format: MM/DD/YY

System Time Format: AM/PM

The Netopia 4753 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 rever t to an internal default date and time for ﬁve minutes until NTP can reconnect to its time ser ver and reset the clock.

You should pick a time server close to your location, if possible. Lists of public time ser vers suppor ted 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 inter val such as ever y 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,

By default, all events are logged in the event history.

■ By toggling each event descriptor to either Yes or No, you can determine which ones are logged and which

are ignored.

■ You can enable or disable the syslog client dynamically. When enabled, it will report any appropriate and

previously unreported events.

■ You can specify the syslog server’s address either in dotted decimal format or as a DNS name up to 63

characters.

■ You can specify the UNIX syslog Facility to use by selecting the Facility pop-up.

Installing the Syslog client

The Goodies folder on the Netopia CD contains a Syslog client daemon program that can be conﬁgured to report the WAN events you speciﬁed in the Logging Conﬁguration screen.

To install the Syslog client daemon, exit from the graphical Netopia CD program and locate the CD directory structure through your Windows desktop or through Windows Explorer. Go to the Goodies directory on the CD and locate the Sds15000.exe program. This is the Syslog daemon installer. Run the Sds15000.exe program and follow the on-screen instructions for enabling the Windows Syslog daemon.

The Netopia 4753 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 10-2

■ “IP Address Serving” on page 10-10

■ “More Address Ser ving Options” on page 10-17

■ “DHCP Relay Agent” on page 10-23

■ “Connection Proﬁles” on page 10-25

Network Address Translation allows communication between the LAN connected to the Netopia 4753 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 4753 from the outside world.

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

For a detailed discussion of Network Address Translation, see Chapter 11, “Multiple Network Address

Translation.”

IP Setup

The IP Setup options screen is where you conﬁgure the Ethernet side of the Netopia 4753. The information you enter here controls how the router routes IP traf ﬁc.

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 Ser ver 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 4753 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.

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

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

Follow these steps to conﬁgure IP setup for your Netopia 4753:

■ Select Ethernet IP Address and enter the IP address for the Netopia 4753’s Ethernet por t.

■ 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 10-4 for details.

IP Setup 10-3

The Netopia 4753 G.SHDSL Integrated Access Device supports multiple IP subnets on the Ethernet interface. You may want to conﬁgure multiple IP subnets to ser vice 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 4753.

A default gateway should be able to successfully route packets when the Netopia 4753 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 4753 when the primar y DNS ser ver 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 4753 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 4753’s Ethernet por t will

accept routing information provided by RIP packets from other routers that use the same subnet mask. Set to v2, the Netopia 4753 will accept routing information provided by RIP packets from other routers that use different subnet masks. Set to Both, the Netopia 4753 will accept information from either RIP v1 or v2 routers.

■ If you want the Netopia 4753 to advertise its routing table to other routers via RIP, select Transmit RIP and

select v1, v2 (broadcast), or v2 (multicast) from the pop-up menu. With Transmit RIP v1 selected, the Netopia 4753 will generate RIP packets only to other RIP v1 routers. With Transmit RIP v2 (broadcast) selected, the Netopia 4753 will generate RIP packets to all other hosts on the network. With Transmit RIP v2 (multicast) selected, the Netopia 4753 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 11-1.

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

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

that the addresses distributed by the Netopia 4753 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 13-4.

10-4 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. Other wise, 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 4753’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 10-5

For example:

■ To 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 ser ving pools conﬁgured on the IP Address Pools screen, and changes on this screen may affect the IP Address Pools screen. In par ticular, 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 4753 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 4753 (see “IP Routing Table” on page 14-9).

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.

The Static Routes screen will appear.

■ Select Destination Network IP Address and enter the network IP address of the destination network.

■ Select Destination Network Subnet Mask and enter the subnet mask used by the destination network.

■ Select Next Gateway IP Address and enter the IP address for the router that the Netopia 4753 will use to

reach the destination network. This router does not necessarily have to be part of the destination network, but it must at least know where to forward packets destined for that network.

■ Select Route Priority and choose High or Low. High means that the static route takes precedence over RIP

IP Setup 10-9

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 4753, 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 Ye s . When Advertise Route Via RIP is toggled to Ye s, 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 STATIC 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 reser ved for the default gateway, which is

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 4753 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 4753.

■ 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.

IP Address

Serving

• Serve DHCP Clients

• Serve BootP Clients

• Serve Dynamic WAN Clients

In addition to being a router, the Netopia 4753 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 4753 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 Ser ving screen will appear.

Serve DHCP Clients: Yes DHCP Lease Time (Hours): 1 DHCP NetBIOS Options...

Serve BOOTP Clients: Yes Serve Dynamic WAN Clients Yes

IP Setup 10-11

Follow these steps to conﬁgure IP Address Ser ving:

■ 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 4753 will

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

Agent” on page 10-23 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 ser ving can also be disabled.

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

Netopia 4753 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 4753 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 ser ving 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.

10-12 Administration Guide

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

IP Address Serving

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 10-13.

IP Setup 10-13

IP Address Pools

The IP Address Pools screen allows you to conﬁgure a separate IP address ser ving 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 reser ved 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 4753’s IP address on the corresponding subnet (or the Netopia 4753’s default gateway, if that gateway is located on the subnet in question). You can override the value by entering any address that is par t of the subnet.

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

10-14 Administration Guide

Numerous factors inﬂuence the choice of served address. It is dif ﬁcult 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 4753 will generally ser ve the ﬁrst unused address from the ﬁrst address pool with an available address. The Netopia 4753 star ts 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 par ticipated in address ser ving 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 4753 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 4753

may construct a pseudo-client identiﬁer for the client. When the client subsequently requests an address, the Netopia 4753 will attempt to serve the address previously associated with the pseudo-client identiﬁer. This is normally the last address ser ved to the client.

■ Otherwise, the Netopia will select the least-recently used available address, star ting 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.

IP Setup 10-15

DHCP NetBIOS Options

If your network uses NetBIOS, you can enable the Netopia 4753 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 industr y standard. It offers LAN applications a variety of “hooks” to carr y 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.

IP Setup 10-17

The Netopia 4753 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 ser ving pool so the addresses will not be

served to clients.

■ The ability to reserve a par ticular IP address for a client with a par ticular 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 ser ving pool(s).

■ The ability to serve as a DHCP Relay Agent.

The Netopia 4753 supports reser ving an IP address only for a type 1 client identiﬁer (i.e., an Ethernet hardware address). It does not support reser ving an IP address for an arbitrary client identiﬁer. (For more information on client identiﬁers, see RFC 2131, section 9.14.)
