accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
„
Reorient or relocate the receiving antenna.
„

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.

Definitions
Before you install or use your new router, 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.
„
A router is a device that forwards messages according to their network
addresses.
„
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”).
The Model 6218 is a Digital Subscriber Line (DSL) modem that may be set by you
to run in bridge or router mode. Because it is most frequently used as a router, that
is how it is referred to in this manual.

Overview
This chapter provides basic instructions for connecting the router to a computer or
a LAN and to the Internet using DSL. The first part provides instructions to set up
the hardware, and the second part describes how to prepare your PC for use with
the router. Refer to Chapter 3, Using the Web Interface for router configuration
instructions.
It is assumed that you have already subscribed to DSL service with your Internet
service provider (ISP).
Connecting the Hardware
Shut down your PC and any other equipment before connecting it to the router. To
connect your router:
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 router, connect it to the
PHONE jack of the router using the cord that came with your telephone. The
router has an internal POTS filter, so you do not need to install one here.
3. Use the included Ethernet cable to connect your computer to the router. Attach
one end of the Ethernet cable to one of the LAN ports on the back of the router
and connect the other end to the Ethernet port or Network Interface Card
(NIC) in your PC.
Connect any other PCs, hubs, and switches to the remaining LAN ports. Either
a crossover or a straight-through Ethernet cable can be used: the router
determines and adjusts to the type of signal required.
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.

Setup Options
Wide Area Network Connection
The DSL (LINE) connection is the Wide Area Network (WAN) connection. It is also
referred to as a broadband connection. The requirements for the WAN connection
depend on your Internet Service Provider (ISP). Most of the configuration you will
perform will be in this area.
Local Area Network Connection
On the other side of your router are your own Local Area Network (LAN)
connections. This is where you plug in your local computers to the router. The
router is normally 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 router, your
LAN consists of that PC.
Saving Changes
Note that the Apply button temporarily saves changes you make. To make
changes permanent, click on Tools (at the top of the page) and select System
Commands. At the System Commands page, click on Save All.

Configuring the WAN
Before the router will pass any data between the LAN interface and the WAN
interface, the WAN side of the router 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 router, the router can simultaneously support
multiple connection types. You must set up different profiles for each connection.
The router supports the following protocols:

„
DHCP
„
PPPoA (RFC 2364)
„
PPPoE (RFC 2516)
„

3. Using the Web Interface
New Connection
A new connection is basically a virtual connection. Your router can support up to 8
different virtual connections. If you have multiple different virtual connections, you
may need to utilize the static and dynamic routing capabilities of the router to pass
data correctly.
PPPoE Connection Setup
PPPoE is defined in the Internet standard RFC 2516. It is a method of
encapsulating PPP packets over Ethernet. PPP (Point-to-Point Protocol) is a
method of establishing a network session between network hosts. It usually
provides a mechanism of authenticating users.
To configure the CPE for PPPoE:
Procedure
1. Click on Setup and then click on New Connection. The default PPPoE
connection setup is displayed.
2. At the Type field, select PPPoE from the drop-down list. The PPPoE
Connection Setup page is displayed.
3. Give your PPPoE connection a unique name. The name must not have spaces
and cannot begin with numbers.
4. Select a PVC Sharing type of Disable, Enable, or VLAN.
5. Select or enter a VPI and VCI (as supplied by your DSL service provider or
your ISP), or click in Auto PVC. Auto PVC causes the router to perform
automatic VPI/VCI detection as defined in DSL forum TR-068.
Caution:
Use Auto PVC only for DSLAMs with an ATM uplink. Do not use Auto PVC
with IP DSLAMs.
6. For VLAN, specify a VLAN ID and priority.
7. Select NAT and Firewall if you want them active for this connection. Firewall
and NAT services must be enabled. See Firewall/NAT Services on page 3-17.
8. Select the quality of service (QOS). Leave the default value if your ISP did not
provide this information. Depending on the QoS you select, you may also
enter:

3. 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).

3. Using the Web Interface
Note: If you change the start or end values, make sure the values are still within
the same subnet as the router's IP address. For example, if the router'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 router if your PC has DHCP enabled.
In addition to the DHCP server feature, the router supports the DHCP relay
function. When the router is configured as DHCP server, it assigns the IP
addresses to the LAN clients. When the router is configured as DHCP relay, it is
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 router must be on the same
subnet as the computers.
The Apply button will temporarily save these settings. To make the change
permanent, click on Tools (at the top of the page) and select System Commands.
At the System Commands page, click on Save All.
Changing the Router's IP address
Your router's default IP address and subnet mask are 192.168.1.1 and
255.255.255.0, respectively. This subnet mask allows the router 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 router’s IP address and you
have DHCP enabled, the DHCP configuration must reside within the same subnet.
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 router.
To change the router's IP address:
Procedure
1. From the Home screen, click on Setup.

Port Forwarding
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 router 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.

Remote Log
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 router 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, you can select Debug if you want to log the
connection information. This is helpful when trying to debug connection problems.
Table 3-2 defines the different severity levels.

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.
2. Specify the target IP Address that you want to ping.
Optionally, specify:
— TOS Byte value. This is part of the IP header of the ping packet. Valid
values are 0 to 255.
— Packet size. Valid values are 36 to 65507.
— Number of echo requests. Valid values are 1 to 9.
3. Click on Test.
By default, when you select ping test, the router will ping itself three times. In
Figure 3-40, the router passed the Ping Test; this basically means that the TCP/IP
protocol is up and running. If this first test does not pass, the TCP/IP protocol is
not loaded. In this case, restart the router.

Modem Test
The Modem Test is used to check whether your router is properly connected to the
WAN Network by running OAM F4 and F5 end-to-end and segment tests. The test
may take a few seconds to complete. To perform the test, select your connection
from the list, select a Test Type, and click on the Test button.
Before running this test, make sure you have a valid DSL link; if the DSL link is not
connected, this test will always fail. Also, the DSLAM must support this feature.
Not all DSLAMs have OAM F4 and F5 support.

The Router Is Not Functional
1. Check to see that the power LED is green and than the network cables are
installed correctly. Refer to Connecting the Hardware in Chapter 2, Hardware
Installation and PC Setup for more details.
2. Check to see that the LAN and STATUS LEDs are green.
3. Check to see that the STATUS LED is green.

4. Check the settings on your PC. Again, refer to the quick start guide for more
details
5. Check the router's settings.
6. From your PC, can you ping the router? Assuming that the router has DHCP
enabled and your PC is on the same subnet as the router, you should be able
to ping the router.
7. Can you ping the WAN? Your ISP should have provided the IP address of their
server. If you can ping the router 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 Router
1. Check to see that the power LED is green and that the network cables are
installed correctly.
2. Make sure that your PC and the router are on the same network segment. The
router's default IP address is 192.168.1.1. If you are running a Windows-based
6218-A2-GB20-10

4. Troubleshooting
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 router's subnet mask. The router has a default subnet mask of
255.255.255.0.
3. 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. The main cause of this is that you are too far away
from the central office. Contact your DSL service provider for further assistance.
Status 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 router. If the phone line is connected to the phone side of the router or
you have a splitter installed on the phone line, the DSL light will not come on.

Terminology
A
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 router 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?
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 router
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 router 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.
What is a DMZ?
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.
6218-A2-GB20-10
July 2005
A-1
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 router. The router 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.
