4.5 Setup ADSL Router via USB Cable on Linux

This driver supports Linux-2.4 kernel.

Compiling the Driver

To compile the driver simply run make in "viking" directory. This will create binary driver

with name VKGEther.

% make

Loading the module

To load the VKGEther module enter the following command as root in directory "viking"

Syntax:

% insmod ./VKGEther {Module Options}

Unloading the module

To unload an unused module:

% rmmod VKGEther

You will need to exit or disconnect any program currently using the module before it

unload. If the module was configured for LAN, shutdown the ethernet interface:

% ifconfig eth1 down

The ethernet interface associated with the VKGEther driver was "eth1" that's why

interface name is eth1 in above line.

LAN Configuration

To enable LAN traffic over the ethernet interface:

% ifconfig eth1 192.168.1.200 up

You may also need to modify the netmask and route for the interface. Refer to the manual

pages for ifconfig and route for more information. To test the LAN connection is alive by

pinging the remote side:

% ping 192.168.1.1

To disconnect the LAN interface:

% ifconfig eth1 down

3) Entry of the User Name and Password will be displayed. Enter the default login

User Name and Password. The default login User Name of the administrator is root,

and the default admin login password is root.

5.2 Home

The Home page displays when you first access the program or, if another tab is already

displaying, when you click on the Home tab.

5.2.1 Home

The System View table provides a snapshot of the device configuration. Note that some

of the settings are links to the software pages that enable you to configure those settings.

Device: Displays basic information about the device hardware and software versions, the

system uptime since the last reboot, and the preconfigured operating mode.

DSL: Displays the operational status, DSL standard conformance, and performance

statistics for the DSL line. You can click DSL in the table heading to display additional DSL

settings.

WAN Interfaces: Displays the software name(s) and settings for the device interfaces that

communicate with the ISP via DSL, such as a PPP, EOA, or IPoA interface. Although the

device has one physical DSL port, multiple software-defined interfaces can be configured

to use it. You can click on the interface names to view the Configuration pages for these

interfaces, or display the Advanced task bar for similar options.

LAN Interfaces: Displays the software names and settings for the device interfaces that

communicate directly with the local network. These typically include at least one Ethernet

interface, named eth-0, and may include a USB interface named usb-0. You can click on

the interface names to display the LAN Configuration page.

Services Summary: Displays any of the following services that ADSL/Ethernet router

performs to help you manage your network:

z Translating private IP addresses to your public IP address (5.7.1-NAT).

z Setting up filtering rules that accept or deny incoming or outgoing data (5.7.4-IP Filter).

z Enabling router-to-router communication (5.7.2-RIP).

z Enabling dynamic assignment of IP information from your ISP to your computers

(5.3.4-DHCP relay), from the device's built-in server to your network (5.3.3-DHCP Server)

or from a computer on your network to the device's LAN interface (DHCP Client).

z Message forwarding based on the Internet Group Management Protocol (IGMP, not

configurable).

5.2.2 System Mode

The System Mode page enables you to configure system-level operating modes that use

bridging in addition or instead of routing protocols. You can also configure a feature in which

the mode is selected automatically at start-up, based on the type of Internet connection

detected on the LAN PC(s).

The current system mode is shown on the System View page that displays when you

access the configuration program. The system mode is not configured using a single

setting. Rather, it is determined at system startup based on whether the device's LAN

and WAN interfaces are configured with IP information (i.e., are "IP-enabled"), and

whether the Bridging setting on the System Mode page is enabled or disabled.

z When the Bridging setting on the System Mode page is disabled, then the system mode

will display as "Routing".

z When the Bridging setting is enabled and at least one LAN or WAN interface is

IP-enabled, then the system mode will display as "Routing and Bridging."

z When the Bridging setting is enabled and no interfaces are IP enabled, then the device is

considered to be in Bridging Mode. Note, however, that in this case you would not be

able to access Configuration Manager; without being IP-enabled, the Ethernet interface

could not communicate using the Internet protocol HTTP, which is used to display

information in your Web browser.

5.2.3 Quick Configuration

The Quick Configuration displays the settings you are most likely to need to change

when you first set up your ADSL/Ethernet router. Work with your ISP to determine the values

or settings you need to change.

NOTE1: It is a strong recommendation that using Quick Configuration to set your ADSL

settings.

NOTE2: When you enter Quick Configuration page, the default ATM Interface value will

be “1”. Please click the drag-down button and choose “

0 ”

z ATM Interface: Selects the ATM interface you want to use (usually 1). Your system may

be configured with more than one ATM interface if you are using different types of

services with your ISP.

z Operation Mode: Enables or disables the device. When set to "Disabled", the device

cannot be used to provide Internet connectivity or routing services for your network.

z Encapsulation: Determines the type of data link used to communicate with your ISP.

z VPI and VCI: Determine the unique data path your modem uses to communicate with

your ISP.

z Bridge: Enables or disables bridging between the device and your ISP.

z IGMP: Can be used to enable the WAN interface to pass Internet Group Management

Protocol messages it receives to the LAN PCs. You must enable the LAN or USB

interfaces for IGMP.

z IP Address and Subnet Mask: If your ISP has provided a public IP address to your LAN,

enter the address and the associated subnet mask in the boxes provided. (Note: In

bridge configurations, the public IP address may be entered on your PC rather than on

the ADSL/Ethernet router; check with your ISP.).

z Use DHCP: When enabled, your ISP will use DHCP to assign an IP address to the WAN

interface. When disabled, the ISP will either use another protocol, or you must manually

assign an IP address to it. See the appropriate WAN interface help topic for PPP or EoA

interfaces.

z Default Route: When enabled, specifies that the WAN interface specified above will be

used as the default route for your LAN. Whenever one of your LAN computers attempts

to access the Internet, the data will be sent via through this interface.

z Gateway IP Address: Specifies the IP address that identifies the ISP server through

which your Internet connection will be routed.

z PPP Username and Password: The username and password you use to log in to your

ISP. (Note: this is not the same as the user name and password you used to log in to

Configuration Manager.)

z Use DNS: Specifies whether the DNS server addresses that your LAN will use should be

supplied dynamically via the PPP connection each time you connect to the ISP.

If you click Disable, you must configure DNS addresses manually on each PC or in the

fields below.

z Primary/Secondary DNS: Specifies the Primary and Secondary DNS server addresses

provided by your ISP.

5.3 LAN

5.3.1 LAN Configuration

Use this page to set the LAN configuration, which determines how your device is

identified on the network.

The LAN Configuration table displays the following settings:

z System Mode: Identifies the system operating mode for your device, such as Routing

mode, Bridging mode, or both modes simultaneously. See Configuring the System Mode

for more information).

z Get LAN Address: Provides options for how the device's LAN interface is assigned an

IP address:

-- Manual indicates that you will be assigning a static IP address, which you can enter in the

fields below.

-- External DHCP Server indicates that your ISP will be assigning an IP address from their

own DHCP servers, dynamically each time you log on.

-- Internal DHCP Server indicates that you have a DHCP server device on your network that

will assign an address to the port.

If you choose either the internal or external server option, the LAN interface is called a

DHCP client of the server.

Note

that the public IP address assigned to you by your ISP is not your LAN IP address.

The public IP address identifies the WAN (ADSL) port on your ADSL/Ethernet router to the

Internet. Or, in bridge configurations, it may be assigned to a PC.

z Speed/Duplex: Speed indicates the speed of the Ethernet communication between the

ADSL/Ethernet router and the LAN PCs or hub. Duplex indicates the type of Ethernet

communication (i.e., full duplex, or half-duplex). These settings are not

user-configurable.

z LAN IP Address and Network Mask: The IP address and network mask for the port.

z IGMP: Indicates whether this interface is enabled with the Internet Group Management

Protocol. When enabled, the ADSL/Ethernet router collects and consolidates requests

from the LAN PCs to receive IGMP messages from external computers. The interface

also forwards IGMP messages it receives on its WAN interface to the appropriate hosts.

The WAN interface must also be enabled for the IGMP protocol.

z MTU: The Maximum Transmission Unit specifies the size in bytes of the largest Ethernet

packet that the interface will accept. Packets larger than this size will be dropped.

5.3.2 DHCP Mode

You can configure your network and ADSL/Ethernet router to use the Dynamic Host

Configuration Protocol (DHCP). This help topic provides an overview of DHCP and

instructions for implementing it on your network.

DHCP is a protocol that enables network administrators to centrally manage the

assignment and distribution of IP information to computers on a network.

The device can be configured as a DHCP server, relay agent, or client.

z If you configure the device as a DHCP server, it will maintain the pool of addresses and

distribute them to your LAN computers. If the pool of addresses includes private IP

addresses, you must also configure the Network Address Translation service, so that the

private addresses can be translated to your public IP address on the Internet. Both

DHCP server and NAT are enabled in the default configuration.

z If your ISP performs the DHCP server function for your network, then you can configure

your device as a DHCP relay agent. When a computer logs onto the network, the

ADSL/Ethernet router contacts your ISP for the necessary IP information, which it relays

back to the computer.

z If you have another PC or device on your network already performing the DHCP server

function, then you can configure the device's LAN port to be a DHCP client of that server

(as are your PCs).

5.3.3 DHCP Server

This topic describes how to configure the DHCP server feature on your ADSL/Ethernet

router.

Adding DHCP Server Address Pools:

1. If the DHCP Server Configuration page is not already displaying, click the LAN tab, and

then click DHCP Server in the task bar.

Depending on your pre-configured settings, the table may display up to two address pools,

each in a row, or may be empty.

2. Click Add. The DHCP Server Pool - Add page displays.

3. Enter values for the Start IP Address, End IP Address, and Net Mask fields, which are

required, and any others as needed:

z Start/End IP Addresses: Specify the lowest and highest addresses in the pool, up to a

maximum range of 254 addresses.

z Mac Address: A MAC address is a manufacturer-assigned hardware ID that is unique

for each device on a network. Use this field only if you want to assign a specific IP

address to a specific computer (that is, you are creating an exception to the dynamic

assignment of addresses). The IP address you specify will be assigned to the computer

that corresponds to this MAC address. If you type a MAC address here, you must have

specified the same IP address in both the Start IP Address and End IP Address fields.

z Net Mask: Specifies which portion of each IP addresses in this range refers to the

network and which portion refers to the host (computer). You can use the net mask to

distinguish which pool of addresses should be distributed to a particular subset of

computers on your LAN (call a subnet).

z Domain Name: A user-friendly name that refers to the subnet that includes the

addresses in this pool.

z Gateway Address: The address of the default gateway for computers that receive IP

addresses from this pool. If no value is specified, then the appropriate LAN (eth-0) or

USB (usb-0) port address on the device will be distributed to each PC as its gateway

address, depending on how each is connected. See Configuring IP Routes for an

explanation of gateway addresses.

z DNS/SDNS: The IP address of the Domain Name System server to be used by

computers that receive IP addresses from this pool. The DNS translates common

Internet names that you type into your web browser into their equivalent numeric IP

addresses. Typically, this server is located with your ISP.

z SMTP...SWINS (optional): The IP addresses of devices that perform various services for

computers that receive IP addresses from this pool (such as the SMTP, or Simple Mail

Transfer Protocol, server which handles e-mail traffic). Contact your ISP for these

addresses.

4. When you are done defining the pool, click Submit.

A confirmation page displays briefly to indicate that the pool has been added successfully.

After a few seconds, the DHCP Server Pool – Add page displays with the newly added pool.

5. Click DHCP Mode in the task bar, then follow the instructions in Setting the DHCP Mode

enable the DHCP server.

5.3.4 DHCP Relay

Some ISPs perform the DHCP server function for their customers' home/small office

networks. In this case, you can configure the device as a DHCP relay agent. When a

computer on your network requests Internet access, the ADSL/Ethernet router connects your

ISP to obtain an IP address and other information, and then forwards that information to the

computer.

Follow these instructions to configure DHCP relay:

First, you must configure each LAN computer to receive IP information assigned by a

DHCP server:

1) Open the Windows Control Panel and display the computer's Networking properties.

Configure the TCP/IP properties to "Obtain an IP address automatically" (the actual text may

vary depending on your operating system).

Next, you specify the IP address of the DHCP server and select the interfaces on your

network that will be using the relay service.

2) If the DHCP Configuration page is not already displaying, click the LAN tab, and then click

DHCP Relay in the task bar.

3) In the DHCP Server Address fields, type the IP address of your ISP's DHCP server.

If you do not have this address, it is not essential to enter it here. Requests for IP

information from your LAN will be passed to the default gateway, which should route the

request appropriately.

4) Select your WAN interface from the drop-down list and click Add.

The WAN interface may be named ppp-0, eoa-0, or ipoa-0. Contact your ISP if you are

unsure which type to use.

(Note that you can delete an interface from the table by clicking

in the right column.)

5) Click Submit. A page displays to confirm your changes, and the program returns to the

DHCP Relay Configuration page.

6) Click DHCP Mode in the task bar, then follow the instructions in Setting the DHCP Mode to

enable DHCP relay.

NOTE

: If want your changes to be permanent, be sure to commit them.

5.3.5 Ethernet Status

you click on 1-4, data displays for the 16 intervals (15-minutes each) that make up the previous

4 hours.

5.4.2 ATM VC

In ATM VC configuration page, you can configure one of the higher level WAN interfaces

to enable communication with your ISP.

Interface: The name of the lower-level interface on which this VC operates. The low-level

interface names are preconfigured in the software and identify the type of traffic that can be

supported, such as data or voice. Internet data services typically use an AAL5-type interface.

VPI, VCI, and Mux Type: These settings identify a unique ATM data path for communication

between your ADSL/Ethernet router and your ISP

Max Proto per AAL5: If you are using an AAL5-type of interface, this setting indicates the

number of higher level interfaces that the VC can support (the higher level interfaces can be

PPP, EoA, or IPoA interfaces). Contact your ISP to determine which connection protocol(s)

they require.

Actions: Displays icons you can click on to modify (

) and delete ( ) the associated

interface. You cannot delete an ATM interface if another protocol such as PPP, EoA, or IPoA

has been defined to operate over the ATM interface. Delete the higher-level interface first, and

then delete the ATM interface.

5.4.3 PPP

The Point-to-Point Protocol (PPP) is one of several protocols used to enable

communication between ISPs and their customers. PPP performs tasks such as the following:

¾ Identifying the type of service the ISP provides to a given customer.

¾ Identifying the customer to the ISP through a username and password login.

¾ Enabling the ISP to assign Internet information to the customer's computers.

You can configure the following settings on the PPP Configuration page:

Inactivity TimeOut...: The time in minutes that must elapse before a PPP connection

times-out due to inactivity. This setting applies only to PPP interfaces that are configured as

"start-on-data" interfaces. This type of interface starts up only when it receives data, and then

returns to a down state after the specified amount of time. This setting works with the following

setting to determine what type of data can activate a start-on-data interface.

Ignore WAN to LAN traffic...: When enabled, data traffic traveling in the incoming direction --

from a WAN interface to the LAN interface -- will not count as activity on the WAN port for the

purposes of determining whether to make it inactive; i.e., WAN to LAN traffic will not activate a

start-on-data interface. Only LAN-to-WAN traffic will start the interface.

The PPP Configuration table displays the following fields:

Interface: The predefined name of the PPP interface.

VC: The Virtual Circuit over which this PPP data is sent. The VC identifies the physical path

the data takes to reach your ISP.

Interface Sec Type: The type of Firewall protections that are in effect on the interface (public,

private, or DMZ):

z A public interface connects to the Internet (PPP interfaces are typically public). Packets

received on a public interface are subject to the most restrictive set of firewall protections

defined in the software.

z A private interface connects to your LAN, such as the Ethernet interface. Packets

received on a private interface are subject to a less restrictive set of protections, because

they originate within the network.

z The term DMZ (de-militarized zone), in Internet networking terms, refers to computers

that are available for both public and in-network accesses (such as a company's public

Web server). Packets incoming on a DMZ interface -- whether from a LAN or external

source -- are subject to a set of protections that is in between public and private

interfaces in terms of restrictiveness.

Protocol: The type of PPP protocol used. Your ISP may use PPP-over-Ethernet (PPPoE) or

PPP-over-ATM (PPPoA).

WAN IP: The IP address currently assigned to your WAN (DSL) port by your ISP.

Gateway IP: The IP address of the server at your ISP that provides you access to the Internet.

Default Route: Indicates whether the ADSL/Ethernet router should use the IP address

assigned to this connection as its default route. Can be Enabled or Disabled.

Use DHCP: When set to Enable, the device will acquire additional IP information from the

ISP's DHCP server. The PPP connection itself acquires the device's IP address, mask, DNS

address, and default gateway address. With Use DHCP enabled, the device will acquire IP

addresses for various other server types (WINS, SMTP, POP3, etc. -- these server types are

listed on the DHCP Server Configuration page).

Use DNS: When set to Enable, the DNS address learned through the PPP connection will be

distributed to clients of the device's DHCP server. This option is useful only when the

ADSL/Ethernet Router is configured to act as a DHCP server for your LAN. When set to

Disable, LAN hosts will use the DNS address(es) pre-configured in the DHCP pool and in the

DNS feature.

Oper. Status: Indicates whether the link is currently up or down or if a specific type of data

exchange is under way (e.g., password authorization or DHCP).

Action(s): Provides icons you can click on to modify (

), delete ( ), or view additional

details on (

) the PPP interface.

5.4.4 EoA

This topic describes how to configure an Ethernet-over-ATM (EoA) interface on the

ADSL/Ethernet router, if one is needed to communicate with your ISP. This interface is also

commonly referred to as an RFC1483 interface, for the name of the Internet specification to

which it conforms.

Interface: The name the software uses to identify the EoA interface.

Interface Sec Type: The type of security protections in effect on the interface (public, private,

or DMZ):

z A public interface connects to the Internet (PPP interfaces are typically public). Packets

received on a public interface are subject to the most restrictive set of firewall protections

defined in the software.

z A private interface connects to your LAN, such as the Ethernet interface. Packets

received on a private interface are subject to a less restrictive set of protections, because

they originate within the network.

z The term DMZ (de-militarized zone), in Internet networking terms, refers to computers

that are available for both public and in-network accesses (such as a company's public

Web server). Packets incoming on a DMZ interface -- whether from a LAN or external

source -- are subject to a level of protection that is in between those for public and private

interfaces.

Lower interface: EoA interfaces are defined in software, and then associated with lower-level

software and hardware structures (at the lowest level, they are associated with a physical port

- the WAN port). This field should reflect an interface name defined in the next lower level of

software over which the EoA interface will operate. This will be an ATM VC interface, such as

aal5-0.

Config IP Address and Net Mask: The IP address and network mask you want to assign to

the interface. If the interface will be used for bridging with your ISP and you will not be using

the device as a router on your LAN, then you do not need to specify IP information. If you

enable DHCP for this interface, then the Configured IP address will serve only as a request to

the DHCP server. The actual address that is assigned by the ISP may differ if this address is

not available.

Use DHCP: When enabled, this setting instructs the device to accept IP information assigned

dynamically by your ISP's DHCP server. If the interface will be used for bridging with your ISP

and you will not be routing data through it, leave this checkbox unselected.

Default Route: Indicates whether the ADSL/Ethernet router should use the IP address

assigned to this interface, if any, as its default route for your LAN. This can be Enable or

Disable.

Gateway Address: The external IP address that the ADSL/Ethernet router communicates with

via the EoA interface to gain access to the Internet. This is typically an ISP server.

Status: A green or red ball will display to indicate that the interface is currently up or down,

respectively. You cannot manually enable or disable the interface; a down interface may

indicate a problem with the DSL connection or the connection to the ISP's access server.

Action: Icons you can click on to edit (

) or delete ( ) the associated EoA interface.

5.4.5 IPOA

This topic describes how to configure an IPoA (Internet Protocol over ATM) interface on

the ADSL/Ethernet router.

Interface: The name the software uses to identify the IPoA interface.

Interface Security Type: The type of firewall protections that are in effect on the interface

(public, private, or DMZ):

z A public interface connects to the Internet (IPoA interfaces are typically public). Packets

received on a public interface are subject to the most restrictive set of firewall protections

defined in the software.

z A private interface connects to your LAN, such as the Ethernet interface. Packets

received on a private interface are subject to a less restrictive set of protections, because

they originate within the network.

z The term DMZ (de-militarized zone), in Internet networking terms, refers to computers

that are available for both public and in-network accesses (such as a company's public

Web server). Packets incoming on a DMZ interface -- whether from a LAN or external

source -- are subject to a level of protection that is in between public and private

interfaces in terms of restrictiveness

RFC 1577: Specifies whether the IPoA protocol to be used complies with the IEFT

specification named "RFC 1577 - Classical IP and ARP over ATM" (contact your ISP if unsure).

Lower interface: An IPoA interface must be associated with one or more ATM VCs that have

been defined on the system. The ATM VC is also considered an interface--one that performs

"lower level" functions (i.e., closer to hardware) than the IPoA interface.

Peer IP Address: The IP address of the remote computer you will be connecting to via the

WAN interface.

Config IP Address and Net Mask: The IP address and network mask you want to assign to

the interface.

Gateway Address: The external IP address that the ADSL/Ethernet router communicates with

via the IPoA interface to gain access to the Internet. This is typically an ISP server.

Status: A green or red ball will display to indicate that the interface is currently up or down,

respectively. You cannot manually enable or disable the interface; a down interface may

indicate a problem with the DSL connection or with the remote peer computer.

5.5 Bridging

5.5.1 Bridging

Use the bridge configuration page to define which device interfaces are capable of

bridging data between your LAN and ISP. Interfaces can be routable (i.e., assigned an IP

address), bridgeable, or both.

Enabling the device to function as a bridge requires two steps:

[Enabling Bridgeable Interfaces]

To enable bridging, you use the Bridge Configuration page to specify the interfaces that

can bridge data. Then, you use the System Mode page to enable the appropriate operating

mode.

1. If the Bridge Configuration page is not already displaying, click the Bridging tab.

The Bridge Configuration Page displays by default.

The page displays Enable/Disable links for Bridging, WAN-to-WAN Bridging, and Zero

Installation PPP bridge (ZIPB). The page also provides a table for specifying the interfaces on

which bridging will be performed. The table may be empty if bridging has not yet been

configured.

2. Select the interface names on which you want to perform bridging and click Add.

[Enabling Bridging Services]

After configuring the bridgeable interfaces, click one of the following links on the Bridge

Configuration Page:

• Bridging: Enable/Disable

• WAN to WAN Bridging: Enable/Disable

• ZIPB: Enable Disable

Each of the links displays the System Mode Page, where you can enable the appropriate

bridging operating mode.

5.5.2 LAN Configuration

This topic allows user to configure the interfaces on the ADSL/Ethernet router that

communicate with your LAN and USB computers.

The LAN Configuration table displays the following settings:

System Mode: Identifies the system operating mode for your device, such as Routing mode,

Bridging mode, or both modes simultaneously.

Get LAN Address: Provides options for how the device's LAN interface is assigned an IP

address.

z Manual indicates that you will be assigning a static IP address, which you can enter in the

fields below.

z External DHCP Server indicates that your ISP will be assigning an IP address from their

own DHCP servers, dynamically each time you log on.

z Internal DHCP Server indicates that you have a DHCP server device on your network

that will assign an address to the port.

If you choose either the internal or external server option, the LAN interface is called a

DHCP client of the server.

Note

that the public IP address assigned to you by your ISP is not your LAN IP address.

The public IP address identifies the WAN (ADSL) port on your ADSL/Ethernet router to the

Internet. Or, in bridge configurations, it may be assigned to a PC.

Speed/Duplex: Speed indicates the speed of the Ethernet communication between the

ADSL/Ethernet router and the LAN PCs or hub. Duplex indicates the type of Ethernet

communication (i.e., full duplex, or half-duplex). These settings are not user-configurable

LAN IP Address and Network Mask: The IP address and network mask for the port.

IGMP: Indicates whether this interface is enabled with the Internet Group Management

Protocol. When enabled, the ADSL/Ethernet router collects and consolidates requests from

the LAN PCs to receive IGMP messages from external computers. The interface also forwards

IGMP messages it receives on its WAN interface to the appropriate hosts. The WAN interface

must also be enabled for the IGMP protocol.

MTU: The Maximum Transmission Unit specifies the size in bytes of the largest Ethernet

packet that the interface will accept. Packets larger than this size will be dropped.

5.5.3 DSL

You can view configuration parameters and performance statistics for the ADSL/Ethernet

Router's DSL line. If the DSL Status page is not already displaying, click the WAN tab. The

DSL page displays by default.

[DSL Status] The DSL Status page displays current information on the DSL line performance.

The page refreshes according to the setting in the Refresh Rate drop-down list, which you can

configure.

In the DSL Status table, the Operational Status setting displays a red, orange, or green ball

to indicate that the DSL line is idle, starting up, or up-and-running, respectively. You can click

Loop Stop to end the DSL connection. To restart the connection, you can click Loop Start.

parameters page, which provides data about the configuration of the DSL line. You cannot

modify this data.

[DSL Statistics] From the DSL Status page, you can click Stats to display DSL line

performance statistics. The DSL Statistics page reports error data relating to the current 15

minute interval, the current day, and the previous day.

5.5.4 ATM VC

The devices WAN-side interfaces are used to communication via the DSL port. A WAN

interface comprises two layers: a lower-level ATM VC interface and a higher-level protocol

interface:

z The ATM VC interface enables the device to communicate using the Asynchronous

Transfer Mode protocol. The ATM protocol provides a common format for transmitting

data over a variety of hardware systems that make up the backbone of the Internet. The

virtual circuit (VC) properties of the ATM VC interface identify a unique path that your

ADSL/Ethernet router uses to communicate via the ATM-based network with the

telephone company central office equipment.

z The higher-level protocol interface(s) operate "on top" of the ATM VC interface. The

higher-level interface handles the protocols needed to log onto and exchange data with

the ISP's access server. ISPs can use several different protocols, including the

Point-to-Point Protocol (PPP), Ethernet-over-ATM (EoA) protocol, or the Internet

Protocol-over-ATM (IPoA). Be sure to create the specific type of WAN interface your ISP

requires.

Interface: The name of the lower-level interface on which this VC operates. The low-level

interface names are preconfigured in the software and identify the type of traffic that can be

supported, such as data or voice. Internet data services typically use an AAL5-type interface.

Vpi, Vci, and Mux Type: These settings identify a unique ATM data path for communication

between your ADSL/Ethernet router and your ISP

Max Proto per AAL5: If you are using an AAL5-type of interface, this setting indicates the

number of higher level interfaces that the VC can support (the higher level interfaces can be

PPP, EoA, or IPoA interfaces). Contact your ISP to determine which connection protocol(s)

they require.

Actions: Displays icons you can click on to modify (

) and delete ( ) the associated

interface. You cannot delete an ATM interface if another protocol such as PPP, EoA, or IPoA

has been defined to operate over the ATM interface. Delete the higher-level interface first, and

then delete the ATM interface.

5.5.5 RFC 1483 Interface (EoA)

The Ethernet-over-ATM (EoA) protocol is commonly used to carry data between local

area networks that use the Ethernet protocol and wide-area networks that use the ATM

protocol. Many telecommunications industry networks use the ATM protocol. ISPs who provide

DSL services often use the EoA protocol for data transfer with their customers' DSL modems.

EoA can be implemented to provide a bridged connection between a DSL modem and the ISP.

In a bridged connection, data is shared between the ISP's network and their customer's as if

the networks were on the same physical LAN. Bridged connections do not use the IP protocol.

EoA can also be configured to provide a routed connection with the ISP, which uses the IP

protocol to exchange data.

Interface: The name the software uses to identify the EoA interface.

Interface Sec Type: The type of security protections in effect on the interface (public, private,

or DMZ):

z A public interface connects to the Internet (IPoA interfaces are typically public). Packets

received on a public interface are subject to the most restrictive set of firewall protections

defined in the software.

z A private interface connects to your LAN, such as the Ethernet interface. Packets

received on a private interface are subject to a less restrictive set of protections, because

they originate within the network.

z The term DMZ (de-militarized zone), in Internet networking terms, refers to computers

that are available for both public and in-network accesses (such as a company's public

Web server). Packets incoming on a DMZ interface -- whether from a LAN or external

source -- are subject to a level of protection that is in between those for public and private

interfaces.

Lower interface: EoA interfaces are defined in software, and then associated with lower-level

software and hardware structures (at the lowest level, they are associated with a physical port

- the WAN port). This field should reflect an interface name defined in the next lower level of

software over which the EoA interface will operate. This will be an ATM VC interface, such as

aal5-0.

Config IP Address and Net Mask: The IP address and network mask you want to assign to

the interface. If the interface will be used for bridging with your ISP and you will not be using

the device as a router on your LAN, then you do not need to specify IP information. If you

enable DHCP for this interface, then the Configured IP address will serve only as a request to

the DHCP server. The actual address that is assigned by the ISP may differ if this address is

not available.

Use DHCP: When enabled, this setting instructs the device to accept IP information assigned

dynamically by your ISP's DHCP server. If the interface will be used for bridging with your ISP

and you will not be routing data through it, leave this checkbox unselected.

Default Route: Indicates whether the ADSL/Ethernet router should use the IP address

assigned to this interface, if any, as its default route for your LAN. This can be Enable or

Disable.

Gateway Address: The external IP address that the ADSL/Ethernet router communicates with

via the EoA interface to gain access to the Internet. This is typically an ISP server.

5.6 Routing

5.6.1 IP Route

IP routes can be created on the ADSL/Ethernet router to specify where it should send

data received on a particular interface. Routes specify the IP address of the next device

interface or Internet destination to forward data to, given the ultimate destination of the data.

A common type of route is a default gateway, which defines the IP address where all data

is forwarded unless an IP route has been defined for the particular destination in question.

Each time data is passed towards its destination from one Internet address to another, it is said

to complete one hop.

Destination: Specifies the IP address of the destination computer. The destination can

specified as the IP address of a specific computer or an entire network. It can also be specified

as all zeros to indicate that this route should be used for all destinations for which no other

route is defined (this is the route that creates the default gateway).

Netmask: Indicates which parts of the destination address refer to the network and which

parts refer to a computer on the network. The default gateway uses a netmask of 0.0.0.0.

NextHop: Specifies the next IP address to send data to when its final destination is that shown

in the destination column.

IfName: Displays the name of the interface through which to data is forwarded to the specified

next hop.

Route Type: Indicates whether the route is direct or indirect. In a direct route, the source and

destination computers are on the same network, and the router attempts to directly deliver the

data to the computer. In an indirect route, the source and destination computers are on

different networks, and the router forwards data to a device on another network for further

handling.

Route Origin: Displays how the route was defined. Dynamic indicates that the route was

predefined on the system by your ISP or the manufacturer. Routes you create are labeled

Local. Other routes may be created automatically (see Configuring RIP), or defined remotely

through various network management protocols (LCL or ICMP).

5.6.2 IP Address Table

The interfaces on your ADSL/Ethernet router that communicate with other network and

Internet devices are identified by unique Internet protocol (IP) addresses. You can use the

Configuration Manager to view the list of IP addresses that your device uses, and to view

other system and network performance data.

The IP Address table lists the IP addresses, network masks ("Net Mask"), and interface

names ("IF Name") for each of its IP-enabled interfaces.

5.6.3 LAN Configuration

This topic describes how to configure the interfaces on the ADSL/Ethernet router that

communicate with your LAN and USB computers.

If you are using the ADSL/Ethernet router with multiple PCs on your LAN, you must

connect the LAN via an Ethernet hub connected to the device's LAN port. If you are using a

single PC with the ADSL/Ethernet router, you have two connection options:

z You can connect the PC directly to the LAN port using a cross-over Ethernet cable. See

your User's Manual for a description of cross-over and straight-through Ethernet cables.

z If the PC is USB-enabled, you can connect it directly to the device's USB port. Only one

computer can be connected in this manner.

You can also use the USB and Ethernet interfaces simultaneously, connecting your LAN to

the Ethernet port and a standalone PC to the USB port.

System Mode: Identifies the system operating mode for your device, such as Routing mode,

Bridging mode, or both modes simultaneously.

Get LAN Address: Provides options for how the device's LAN interface is assigned an IP

address:

z Manual indicates that you will be assigning a static IP address, which you can enter in the

fields below.

z External DHCP Server indicates that your ISP will be assigning an IP address from their

own DHCP servers, dynamically each time you log on.

z Internal DHCP Server indicates that you have a DHCP server device on your network

that will assign an address to the port.

Speed/Duplex: Speed indicates the speed of the Ethernet communication between the

ADSL/Ethernet router and the LAN PCs or hub. Duplex indicates the type of Ethernet

communication (i.e., full duplex, or half-duplex). These settings are not user-configurable.

LAN IP Address and Network Mask: The IP address and network mask for the port.

IGMP: Indicates whether this interface is enabled with the Internet Group Management

Protocol. When enabled, the ADSL/Ethernet router collects and consolidates requests from

the LAN PCs to receive IGMP messages from external computers. The interface also forwards

IGMP messages it receives on its WAN interface to the appropriate hosts. The WAN interface

must also be enabled for the IGMP protocol.

MTU: The Maximum Transmission Unit specifies the size in bytes of the largest Ethernet

packet that the interface will accept. Packets larger than this size will be dropped.

5.6.4 DSL

The DSL Status page displays current information on the DSL line performance. The page

refreshes according to the setting in the Refresh Rate drop-down list, which you can configure.

In the DSL Status table, the Operational Status setting displays a red, orange, or green ball

to indicate that the DSL line is idle, starting up, or up-and-running, respectively. You can click

Loop Stop to end the DSL connection. To restart the connection, you can click Loop Start.

5.6.5 ATM VC

The devices WAN-side interfaces are used to communication via the DSL port. A WAN

interface comprises two layers: a lower-level ATM VC interface and a higher-level protocol

interface:

z The ATM VC interface enables the device to communicate using the Asynchronous

Transfer Mode protocol. The ATM protocol provides a common format for transmitting

data over a variety of hardware systems that make up the backbone of the Internet. The

virtual circuit (VC) properties of the ATM VC interface identify a unique path that your

ADSL/Ethernet router uses to communicate via the ATM-based network with the

telephone company central office equipment.

z The higher-level protocol interface(s) operate "on top" of the ATM VC interface. The

higher-level interface handles the protocols needed to log onto and exchange data with

the ISP's access server. ISPs can use several different protocols, including the

Point-to-Point Protocol (PPP), Ethernet-over-ATM (EoA) protocol, or the Internet

Protocol-over-ATM (IPoA). Be sure to create the specific type of WAN interface your ISP

requires.

Interface: The name of the lower-level interface on which this VC operates. The low-level

interface names are preconfigured in the software and identify the type of traffic that can be

supported, such as data or voice. Internet data services typically use an AAL5-type interface.

Vpi, Vci, and Mux Type: These settings identify a unique ATM data path for communication

between your ADSL/Ethernet router and your ISP.

Max Proto per AAL5: If you are using an AAL5-type of interface, this setting indicates the

number of higher level interfaces that the VC can support (the higher level interfaces can be

PPP, EoA, or IPoA interfaces). Contact your ISP to determine which connection protocol(s)

they require.

5.6.6 PPP

The Point-to-Point Protocol (PPP) is one of several protocols used to enable

communication between ISPs and their customers. PPP performs tasks such as the following:

z Identifying the type of service the ISP provides to a given customer.

z Identifying the customer to the ISP through a username and password login.

z Enabling the ISP to assign Internet information to the customer's computers.
