Configuring EOA Interfaces

This chapter describes how to configure an Ethernet-over-ATM interface on the ATU-R130, if one

is needed to communicate with your ISP.

Viewing Your EOA Setup

{

XE "EOA:settings"

}

To view your current EOA configuration, log into Configuration Manager,

click

Advanced

in the task bar, and then click

EOA

.

Figure 41 shows the EOA configuration page.

Figure 40. EOA Page{ XE "EOA page" }{ XE "Pages:EOA" }

The EOA table contains a row for each EOA interface currently defined on the device. The table

may contain no entries if your ISP does not use the EOA protocol.

The following table describes the fields on this page:

Field

Description

Interface

The name the software uses to identify the EOA

interface.

IPF Type

The type of IP Firewall protections in effect on the

interface (public, private, or DMZ):

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.

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.

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 VCC interface, such as

aal5-0.

Field

Description

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

ATU-R130 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 checked, 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 ATU-R130 should use the IP

address assigned to this interface, if any, as its default

route for your LAN. This can be

Enable

or

Disable

.

See Chapter 8 for an explanation of default routes.

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 red

ball may indicate a problem with the DSL connection.

Action

Icons you can click on to edit (

) or delete (

) the

associated EOA interface.

Adding EOA Interfaces

Follow these instructions to add an EOA interface:

1.

Click the WAN tab, and then click

EOA

in the task bar.

2.

Click

.

The EOA Interface – Add page displays, as shown in Figure 42.

Figure 41. EOA Interface – Add Page{ XE "EOA Interface – Add page" }{ XE "Pages:EOA Interface -

Add" }

3.

Select one of the predefined interface names from the EOA Interface drop down list.

4.

From the IPF Type drop-down list, select the level of IP Firewall to be used on this

interface, as defined above.

5.

In the Lower Interface field, select the lower-level interface name over which this

protocol is being configured. Typically, an EOA interface is configured to operate over

an aal5 interface, such as

aal5-0

.

If you are using the ATU-R130 as a bridge only, skip to step 7.

6.

If you are using the ATU-R130 as a router on your LAN, enter the IP address and

network mask you want to assign to the interface. This address serves as the public IP

address for your entire LAN and is usually assigned by your ISP.

Or, if your ISP will assign this information, click the Enable radio button to set up the DHCP

service.

Also, specify whether this interface should serve as the default route for your LAN for

accessing the Internet.

7.

Click

.

A confirmation page display to confirm your changes.

8.

Click

to return to the EOA page and view the new interface in the table.

9.

Click the Admin tab, and then click

Commit & Reboot

in the task bar.

10.

Click

to save your changes to permanent memory.

Configuring IPoA Interfaces

{

XE "IPOA:defined"

}

This chapter describes how to configure an IPoA (Internet Protocol-over-

ATM) interface on the ATU-R130.

Viewing Your IPoA Interface Setup

To configure an IPoA interface, log into Configuration Manager, click the WAN tab, and then click

IPoA

in the task bar. The IPoA page displays, as shown in Figure 43.

Figure 42. IPoA Page{ XE "IPoA page" }{ XE "Pages:IPoA" }

The IPoA table contains a row for each EOA interface currently defined on the device. The table

may initially contain no entries.

The following table describes the fields on this page:

Field

Description

Interface

The name the software uses to identify the IPoA

interface

IPoA Type

Specifies whether or not the IPoA protocol to be

used complies with the IEFT RFC 1577 "Classical

IP and ARP over ATM" (contact your ISP if

unsure).

Lower interface

IPoA 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 IPoA

interface will operate. This will be an ATM VCC

interface, such as

aal5-0

.

Peer IP Address

The IP address of the remote computer you will be

connecting to via the WAN interface.

IPF Type

The type of IP Firewall protections that are in

effect on the interface (public, private, or DMZ):

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.

A

private

interface connects to your LAN,

such as the Ethernet interface. Packets received

on a private interface are subject to a less

originate within the network.

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.

Config IP Address

and Net Mask

The IP address and network mask you want to

assign to the interface.

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.

the associated EOA interface.

Adding IPoA Interfaces

Follow these instructions to add an IPoA interface:

1.

Display the IPoA page and click

.

The IPoA Interface – Add page displays, as shown in Figure 44.

Figure 43. IPoA Interface – Add Page{ XE "IPoA Interface – Add

2.

Select the next available interface name from the IPoA Interface drop-down list.

3.

In the Configured IP Address and Net Mask boxes, type the address and mask that you

want to assign to the IPoA interface.
