Notice to Users of the United States Telephone Network

The following notice applies to versions of the modem that have been FCC Part 68 approved.

This equipment complies with Part 68 of the FCC rules and the requirements adopted by the Administrative Council for Terminal Attachment (ACTA). On the bottom side of this equipment is a label that contains, among other information, a product identifier in the format US:AAAEQ##TXXXX. If requested, this number must be provided to the Telephone Company.

This equipment is intended to connect to the Public Switched Telephone Network through a Universal Service Order Code (USOC) type RJ11C jack. A plug and jack used to connect this equipment to the premises wiring and telephone network must comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA. A compliant telephone cord and modular plug is provided with this product. It has been designed to be connected to a compatible modular jack that is also compliant.

The Ringer Equivalence Number (or REN) is used to determine the number of devices that may be connected to a telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the total RENs, contact the local Telephone Company. The REN for this product is part of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point. For example, 03 represents a REN of 0.3.

If the modem causes harm to the telephone network, the Telephone Company will notify you in advance that temporary discontinuance of service may be required. But if advance notice is not practical, the Telephone Company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.

The Telephone Company may make changes in its facilities, equipment, operations or procedures that could affect the operation of the equipment. If this happens, the Telephone Company will provide advance notice in order for you to make necessary modifications to maintain uninterrupted service. If trouble is experienced with the modem, refer to the repair and warranty information in this document.

If the equipment is causing harm to the telephone network, the Telephone Company may request that you disconnect the equipment until the problem is resolved.

The user may make no repairs to the equipment.

Connection to party line service is subject to state tariffs. Contact the state public utility commission, public service commission or corporation commission for information.

If the site has specially wired alarm equipment connected to the telephone line, ensure the installation of the modem does not disable the alarm equipment. If you have questions about what will disable alarm equipment, consult your Telephone Company or a qualified installer.

Introduction

Definitions

Before you install or use your new modem, you may find it helpful to understand the following terms:

 A bridge is a device that forwards any message from one part of a network to

another. The 6210 is a bridge.

 A router is a device that forwards messages according to their network

addresses. The 6211 can be configured as a bridge or a router.

 ADSL is Asymmetric Digital Subscriber Line, a version of DSL that allows a

higher speed for information coming from the Internet to your PC (“downstream”) than it does for information going to the Internet from your PC (“upstream”).

Both the 6210 and 6211 contain an ADSL2+ modem, so they often are referred to as modems in this manual.

Features of the 6210 Bridge and 6211 Bridge/Router

Your modem has the following features:

 ADSL2+ support

 10/100BaseT Ethernet port

 USB port

 The ability to connect multiple PCs to the Internet with just one WAN IP

Address (when configured in router mode with NAT enabled)

 A user-friendly web interface for configuration and monitoring

 Single-session IPSec and PPTP passthrough for Virtual Private Network

(VPN)

 Preconfigured port settings for many popular games

 Ability to act as a DHCP Server on your network

 Compatibility with virtually all standard Internet applications

6210-A2-GB23-00 January 2005 1-1

1. Introduction

 Address filtering and DMZ hosting

 Downloadable flash software upgrades

 Support for up to 8 Permanent Virtual Circuits (PVCs)

 Support for up to 2 PPPoE sessions

System Requirements

In order to use your modem for Internet access, you must have the following:

 ADSL service subscription from your ISP.

 One computer with an Ethernet 10/100BaseT network interface card (NIC) or

a free USB port.

 (Optional) An Ethernet hub or switch, if you are connecting the device to

several computers on an Ethernet network.

 For system monitoring or configuration using the supplied web interface, a

web browser such as Internet Explorer Version 5.5 or later.

Ports and Buttons (Back Panel)

 POWER is where you connect the power supply.

 RESET Button: The RESET button is used to reset the modem to factory

default settings. Do not use the RESET button unless advised to by your service representative.

 LAN (Local Area Network) port: This is used to connect to Ethernet network

devices, such as a PC, hub, switch, or router.

 USB (Universal Serial Bus port): Connects to a PC's serial port. The modem

supports Windows-based PCs using an RNDIS driver (included on the CD).

 PHONE port: This allows a phone to directly connect to the modem. You do

not need to add splitter to the phone you connect here, since the modem has an internal splitter.

 LINE port: This is the DSL interface which connects directly to your phone line.

LED Description (Front Panel)

 Power LED: On indicates that the power is supplied to the modem.

 Status LED: The Status LED serves two purposes. If the LED is continuously

lit, the DSL interface is successfully connected to a device through the LINE port. If the LED is flickering, it is an indication that the modem is training (negotiating the connection to its partner modem).

 Activity LED: The Activity LED shows the state of the PPPoA or PPPoE

connection. Off: no PPP connection is established or the connection is not used. Blinking: a PPP connection is being attempted. Solid green: a PPP connection is established. If the LED is flickering, it is an indication of network activity.

 LAN LED: The LAN LED serves two purposes. If the LED is continuously lit,

the Ethernet interface is successfully connected to a device through the LAN port. If the LED is flickering, it is an indication of network activity.

 USB LED: The USB LED serves two purposes. If the LED is continuously lit,

the USB interface is successfully connected to a device through the LAN port. If the LED is flickering, it is an indication of network activity.

It is assumed that you have already subscribed to DSL service with your telephone company or other Internet service provider (ISP).

Connecting the Hardware

Shut down your PC before connecting the modem. To connect your modem:

Procedure

1. Connect the supplied modular phone cable to the LINE port, and connect the other end of the cable to your phone jack.

2. If you would like to use a phone in the vicinity of the modem, connect it to the PHONE jack of the modem using the cord that came with your telephone. The modem has an internal POTS filter, so you do not need to install one here.

3. Connect the USB port, the LAN port, or both.

— If you are connecting the modem directly to a PC (rather than to a LAN),

you can use either the USB port or the LAN port. (Do not connect both the USB port and the LAN port to the same PC.)

To use the USB port, connect the supplied USB cable to the USB port of the modem, then connect the other end of the cable to a free USB port on your PC.

When you start your PC (in a later step), Windows will detect the new hardware and initiate the Found New Hardware Wizard. Follow the instructions under Windows USB Driver Installation on page 2-3.

— Alternatively, you can use the included Ethernet cable to connect your

computer directly to the modem. Attach one end of the supplied Ethernet

cable to the LAN port and connect the other end to the 10/100BaseT port on the network interface card in your PC.

— If your LAN has more than one computer, you can attach one end of an

Ethernet cable to a hub or a switch and the other to the port labeled LAN on the modem. This probably will require an Ethernet crossover cable. See the documentation for your hub or switch to be sure.

4. Connect the cylindrical power plug into the POWER connector on the back of the device. Next:

— If you have a wall-mount adapter, plug the AC adapter into a wall outlet or

a power strip.

— If you have a table-top adapter, use the AC power cord to connect the

adapter to a wall outlet or power strip.

The supplied power adapter may look different than the one illustrated here.

5. Turn on your PC any other LAN devices, such as hubs or switches.

Configuring Your PC

Before you start to access the modem via Ethernet, you must configure your PC's TCP/IP address to be 192.168.1.x, where x is any number between 2 and 254. The subnet mask must be 255.255.255.0. Your modem's default IP address is

192.168.1.1.

If you used the Ethernet cable to connect your modem and PC, you do not need any specific driver installation and you can skip Windows USB Driver Installation, below. If you used the USB cable on a PC running a Windows operation system, install the provided USB driver.

Windows 95 and Windows NT 4.0 do not support USB without additional software (not included with your modem). If USB driver installation fails under those operating systems, contact your service provider.

Windows USB Driver Installation

Figure 3-3. Setup Page

Wide Area Network Connection

The DSL connection is the Wide Area Network (WAN) connection. The requirements for the WAN connection depend on your Internet Service Provider (ISP). When you first log in you will see a default WAN connection (named WAN Bridge) is already defined.

Local Area Network Connection

On the other side of your modem are your own Local Area Network (LAN) connections. This is where you plug in your local computers to the modem. The modem can be configured to automatically provide all the PCs on your network with Internet addresses.

If you connected a PC (rather than a hub or a switch) directly to the modem, your LAN consists of that PC.

3. Using the Web Interface

Configuring the WAN

Before the modem will pass any data between the LAN interface and the WAN interface, the WAN side of the modem must be configured. Depending upon your ISP, you will need some or all of the information listed below before you can properly configure the WAN:

 Your DSL line’s Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI)

 Your DSL encapsulation type and multiplexing mode

 Your DSL training mode (default is MMODE)

If you use PPPoA or PPPoE, you also need these values from your ISP:

 Your username and password

If you use multiprotocol encapsulation over ATM Adaptation Layer 5 (as described in RFC 1483), you may need these values from your ISP:

 Your DSL fixed Internet IP address

 Your subnet mask

 Your default gateway IP address

 Your primary DNS IP address

Since multiple users can use the modem, the modem can simultaneously support multiple connection types. You must set up different profiles for each connection. The 6211 router supports the following protocols:

 DHCP

 PPPoA (RFC 2364)

 PPPoE (RFC 2516)

 Static

 Bridged

The 6210 supports only bridged connections.

3-4 January 2005 6210-A2-GB23-00

4. The DHCP server is enabled when “Enable DHCP Server” is selected. If you enable it:

— Specify a Start IP address. The Start IP Address is where the DHCP

server starts issuing IP addresses. This value must be greater than the router's IP address value. For example, if the router's IP address is

192.168.1.1 (the default) than the Start IP address must be 192.168.1. 2 or higher.

— Specify an End IP address. The End IP Address is the last address the

DHCP server can issue. The ending address cannot exceed a subnet limit of 254. The maximum IP address for a router using the default address is

192.168.1.254. If the DHCP server runs out of DHCP addresses, users will not get access to network resources.

— Specify a Lease Time. The Lease Time is the amount of time a network

user will be allowed connection to the Router with their current dynamic IP address. The amount of time is in units of seconds; the default value is 3600 seconds (1 hour).

Note: If you change the start or end values, make sure the values are still within the same subnet as the modem's IP address. For example, if the modem's IP address is 192.168.1.1 (the default), and you change the DHCP Start and End IP addresses to be 192.128.1.2 and 192.128.1.100, you will not be able to communicate with the modem if your PC has DHCP enabled.

In addition to the DHCP server feature, the modem supports the DHCP relay function. When the modem is configured as DHCP server, it assigns the IP addresses to the LAN clients. When the modem is configured as DHCP relay, it is

3-16 January 2005 6210-A2-GB23-00

Page 45

responsible for forwarding the requests and responses negotiating between the DHCP clients and the server.

If the DHCP server and relay are turned off, you must configure the IP address, subnet mask and DNS settings of every computer on your network. Do not assign the same IP address to more than one computer. Your modem must be on the same subnet as the computers.

Changing the Modem's IP address

Your modem's default IP address and subnet mask are 192.168.1.1 and

255.255.255.0, respectively. This subnet mask allows the modem to support 254 users. Since the DHCP server issues a maximum of 255 addresses, there is not much advantage to changing the subnet mask to increase the number of addresses. Further, remember that if you change your modem’s IP address and you have DHCP enabled, the DHCP configuration must reside within the same subnet.

3. Using the Web Interface

The default gateway is the routing device used to forward all traffic that is not addressed to a station within the local subnet. Your ISP will provide you with the default gateway address.

The Hostname can be any alphanumeric word beginning with a letter and containing no spaces. The domain name is used to in conjunction with the host name to uniquely identify the modem.

To change the modem's IP address:

Procedure

1. From the Home screen, click on Setup.

Port Forwarding (6211 Only)

Using the Port Forwarding page you can provide local services (such as web hosting) for people on the Internet. When users send this type of request to your network via the Internet, the modem will forward those requests to the appropriate PC. Port forwarding can be used with DHCP-assigned addresses, but remember that a DHCP address is dynamic. If you were configuring a Netmeeting server, for example, you would want to assign this server a static IP address so that the IP address is not reassigned. Also remember that if an Internet user is trying to access an Internet application, they must use the WAN IP address. The port forwarding feature will translate the WAN IP address into a LAN IP address.

You can use the LAN Clients screen to reserve an IP address for a DHCP client. See LAN Clients (6211 Only) on page 3-23.

Bridge Filters

The bridge filtering mechanism provides a way for the users to define rules to allow or deny frames through the bridge based on source MAC address, destination MAC address and/or frame type. When bridge filtering is enabled, each frame is examined against the defined filter rules sequentially, and when a matched is determined, the appropriate filtering action (allow or deny) is performed. The bridge filter will only examine frames from interfaces which are part of the bridge itself. Twenty filter rules are supported with bridge filtering.

To enable Bridge Filters:

Procedure

1. From the Home screen, click on Advanced.

2. Under Advanced, select Bridge Filters. The Bridge Filters screen appears, as shown in Figure 3-19, Bridge Filters.

The User Interface for Bridge Filter allows the user to add, edit, and delete, as well as enable the filter rules. To add rules, define the source MAC address, destination MAC address, and frame type with the desired filtering action (allow or deny), and click on the Add button. The MAC address must be in a xx-xx-xx-xx-xx-xx format, with 00-00-00-00-00-00 or blanks meaning any address.

To edit or modify an existing filter rule, select the desired rule created previously in the Edit select box. The selected filter rule appears in the top section, as with the Add procedure. Make the desired change to the MAC address, frame type and access type, and click on Apply.

To delete a filter rules, select the filter rule entry to delete in the Delete selection box. Note that multiple deletions are possible. Once all the desired filter rules are selected for deletion, click on the Apply button. The Select All select box can also

Static Routing (6211 Only)

If the modem is connected to more than one network, you may need to set up a static route between the networks. A static route is a predefined pathway that network information must travel to reach a specific host or network. You can use static routing to allow different IP domain users to access the Internet through the modem.

To enable Static Routing:

Procedure

1. From the Home screen, click on Advanced.

2. Under Advanced, select Static Routing.

3. Specify the New Destination IP. This is the address of the remote LAN network or host to which you want to assign a static route. Enter the IP address of the host for which you wish to create a static route here. For a standard Class C IP domain, the network address is the first three fields of the New Destination IP, while the last field should be 0. The Subnet Mask identifies which portion of an IP address is the network portion, and which portion is the host portion. For a full Class C Subnet, the Subnet Mask is 255.255.255.0.

4. Specify the Gateway address. This is the IP address of the device that allows contact between the modem and the remote network or host.

Dynamic Routing (6211 Only)

Dynamic Routing allows the CPE to automatically adjust to physical changes in the network. The CPE, using the RIP protocol, determines the network packets' route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network.

To enable Dynamic Routing:

Procedure

1. From the Home screen, click on Advanced.

2. Under Advanced, select Dynamic Routing.

3. Specify the Protocol. The protocol is dependent upon the entire network. Most networks support RIP v1. If RIP v1 is selected, routing data will be sent in RIP v1 format. If RIP v2 is selected, routing data will be sent in RIP v2 format using subnet broadcasting. If RIP V1 Compatible is selected, routing data will be sent in RIP v2 format using multicasting.

4. Specify the Direction. This determines the direction that RIP routes will be updated. Selecting In means that the router will only incorporate received RIP information. Selecting Out means that the router will only send out RIP information. Selecting both means that the router will incorporate received RIP information and send out updated RIP information.

Remote Log

3. Using the Web Interface

The remote log feature forwards all logged information to a remote PC. The type of information forwarded to the remote PC depends upon the log level. Each log message is assigned a severity level, which indicates how seriously the triggering event affects modem functions. When you configure logging, you must specify a severity level for each facility. Messages that belong to the facility and are rated at that level or higher are logged to the destination.

For PPPoE and PPPoA connections, select Debug if you want to log the connection information. This is helpful when trying to debug connection problems. Verify that the Debug box is checked on the PPPoA or PPPoE Connection Setup screen.

Ping Test

Once you have your router configured, it is a good idea to make sure you can ping the network. If you have your PC connected to the router via the default DHCP configuration, you should be able to ping the network address 192.168.1.2. If your ISP has provided their server address you can try to ping that address. If the pings for both the WAN and the LAN side are successful, and you have the proper protocols configured, you should be able to access the Internet.

To run a ping test:

Procedure

1. From the Home screen, under the Tools title, click on Ping Test.

Troubleshooting

The Modem Is Not Functional

1. Check to see that the POWER LED is green and the network cables are installed correctly. Refer to Chapter 2, Hardware Installation and PC Setup.

2. Make sure you are not connecting the USB and the Ethernet port to the same PC at the same time.

3. Check to see that the LAN and STATUS LEDs are green.

4. Check the settings on your PC. Refer to Configuring Your PC on page 2-3.

5. Check the modem's settings.

6. From your PC, can you ping the modem? Assuming that the modem has DHCP enabled and your PC is on the same subnet as the modem, you should be able to ping the modem.

7. Can you ping the WAN? Your ISP should have provided the IP address of their server. If you can ping the modem and your protocols are configured correctly, you should be able to ping the ISP's network. If you cannot ping the ISP's network, make sure you are using the correct protocols with the correct VPI/VCI values.

8. Make sure NAT is enabled if you are using private addresses on the LAN ports.

You Cannot Connect to the Modem

1. Check to see that the POWER LED is green and that the network cables are installed correctly.

2. Make sure you are not connecting the USB and the Ethernet port to the same PC at the same time.

3. Make sure that your PC and the modem are on the same network segment. The modem's default IP address is 192.168.1.1. If you are running a Windows-based PC, type ipconfig /all (or winipcfg /all on Windows 95, 98, or ME) at a command prompt to determine the IP address of your network adapter. Make sure that it is within the same 192.168.1.x subnet. Your PC's subnet mask must match the modem's subnet mask. The modem has a default subnet mask of 255.255.255.0.

4. Make sure NAT is enabled if you are using private addresses on the LAN ports.

LEDs Blink in a Sequential Pattern

This typically means that either the kernel or flash file system is corrupted. Notify your service representative.

Status LED Continues to Blink

This means that the DSL line is trying to train but for some reason it cannot establish a valid connection. A possible cause of this is that you are too far away from the central office. Contact your DSL service provider for further assistance.

The Status Link LED is Always Off

1. Make sure you have DSL service. You should receive notification from your ISP that DSL service is installed. You can usually tell if the service is installed by listening to the phone line: you will hear some high-pitched noise. If you do not hear high-pitched noise, contact your ISP.

2. Verify that the phone line is connected directly to the wall and to the line input on the modem. If the phone line is connected to the phone side of the modem or you have a splitter installed on the phone line, the Status LED will not come on.

Terminology

What is a Firewall?

A firewall is protection between the Internet and your local network. It acts as the firewall in your car does, protecting the interior of the car from the engine. Your car's firewall has very small opening that allow desired connections from the engine into the cabin (gas pedal connection, etc), but if something happens to your engine, you are protected.

The firewall in the modem is very similar. Only the connections that you allow are passed through the firewall. These connections normally originate from the local network, such as users web browsing, checking e-mail, downloading files, and playing games. However, you can allow incoming connections so that you can run programs like a web server.

What is NAT?

What is a DMZ?

NAT stands for Network Address Translation. Another name for it is Connection Sharing. What does this mean? Your ISP provides you with a single network address to access the Internet with. However, you may have several machines on your local network that want to access the Internet at the same time. The modem provides NAT functionality that converts your local network addresses to the single network address provided by your ISP. It keeps track of all these connections and makes sure that the correct information gets to the correct local machine.

Occasionally, there are certain programs that don't work well through NAT. Some games and other specialty applications have a bit of trouble. The modem contains special functionality to handle the vast majority of these troublesome programs and games. NAT does cause problems when you want to run a server. See the DMZ section below.

DMZ really stands for Demilitarized Zone. It is a way of separating part of your local network so that is more open to the Internet. Suppose that you want to run a web server, or a game server. Normal servers like these are blocked from working by the NAT functionality. The solution is to isolate the single local computer into a DMZ. This makes the single computer look like it is directly on the Internet, and others can access this machine.

A. Terminology

Your machine isn't really directly connected to the Internet, and it really has an internal local network address. When you provide the server's network address to others, you actually provide the address of the modem. The modem fakes the connection to your machine.

You should use the DMZ when you want to run a server that others will access from the Internet. Internal programs and servers (like print servers) should not be connected to the DMZ.

What is a Router?

The Internet is so large that a single network cannot handle all of the traffic and still deliver a reasonable level of service. To overcome this limitation, the network is broken down into smaller segments or subnets that can deliver good performance for the stations attached to that segment. This segmentation solves the problem of supporting a large number of stations, but introduces the problem of getting traffic from one subnet to another.

To accomplish this, devices called routers are placed between segments. If a machine wishes to contact another device on the same segment, it transmits to that station directly using a simple discovery technique. If the target station does not exist on the same segment as the source station, then the source actually has no idea how to get to the target.

One of the configuration parameters transmitted to each network device is its default gateway. This address is configured by the network administrators and it informs each personal computer or other network device where to send data if the target station does not reside on the same subnet as the source. If your machine can reach all stations on the same subnet (usually a building or a sector within a building), but cannot communicate outside of this area, it is usually because of an incorrectly configured default gateway.
