The PPP{ XE "PPP:settings" } Configuration Table displays the following fields:

Field

Description

Interface

The predefined name of the PPP interface.

VCC

The Virtual Channel Connection over which this PPP

data is sent. The VCC identifies the physical path the

data takes to reach your ISP.

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 (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.

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 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 (PPoE) or PPP-over-ATM

(PPoA).

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).

User 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) preconfigured in the DHCP pool (see

“Configuring DHCP Server” on page 23)

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).

Actions

You can use these icons to modify (

), delete (

),

and view additional details on (

) the PPP interface.

Viewing PPP Interface Details

When you click

to view additional details, the PPP Interface - Detail page displays, as shown

in Figure 38

Figure 37. PPP – Detail Page{ XE "PPP – Detail page" }{ XE "Pages:PPP - Detail" }

In addition to the properties defined on page 49, he Detail page displays these fields:

Field

Description{ XE "PPP:settings" }

Status

Indicates whether the interface has been specified in the

system as:

Enabled: A connection will be established for use

when the device is turned on or rebooted.

Disabled: The PPP interface cannot currently be

used.

Start On Data: The PPP connection will be

made only when data is sent to the interface (e.g., when

a LAN user attempts to use the Internet).

Service Name

The name of the ISP service you are using with this PPP

connection. ISPs may offer different types of services (for

example, for online gaming or business

communications), each requiring a different login and

other connection properties.

Field

Description{ XE "PPP:settings" }

Last Fail Cause

Indicates the action that ended the previous PPP

session:

No Valid PADO Recvd: The unit initiated a PPoE

handshake but did not receive a packet in reply from the

ISP.

No Valid PADS Recvd: After the initial handshake,

the unit did not receive a confirmation packet from the

ISP.

Stopped by User: The user stopped the connection

(for example, by changing the Configuration Manager

settings for the PPP interface.)

No Activity: The PPP communication timed out, in

accordance with the timeout period specified on the PPP

Configuration page.

Auth Failure: The ISP could not authorize the

connection based on the user name and/or password

provided.

PADT recvd: The ISP issued a special packet type

to terminate the PPP connection.

VC down: The Virtual Circuit between the unit and

the ISP is down.

Internal failure: A system software failure occurred.

DNS

The IP address of the DNS server (located with your

ISP) used on this PPP connection.

SDNS

The IP address of the secondary DNS server (located

with your ISP) used on this PPP connection.

Security

Protocol

The type of PPP security your ISP uses:

PAP

(Password

Authentication Protocol) or

CHAP

(Challenge

Handshake Authentication Protocol).

Login Name

The name you use to log in to your ISP each time this

PPP connection is established.

Adding a PPP Interface Definition

If you intend to use more than one type of service from your ISP, the device may be configured

with multiple PPP interfaces, each with unique logon and other properties. Follow this procedure

to define properties for a PPP interface:

1.

From the PPP Configuration Page, click

.

The PPP Interface – Add page displays, as shown in Figure 39.

Figure 38. PPP Interface – Add Page{ XE "PPP Interface – Add page" }{ XE "Pages:PPP Interface -

Add" }

2.

Select a PPP interface name from the drop-down list, and then enter or select data for

each field.

Note

You can create multiple PPP interfaces only if you are using the

PPoA protocol; only one PPP interface can be define if you are

using PPoE. Check with your ISP which version of the protocol

they require.

The fields are defined in the tables on page 49 and 50.

3.

Click

.

A page displays to confirm your changes.

4.

Click

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

5.

Click the Admin tab, and then click

Commit & Reboot

in the task bar.

6.

Click

to save your changes to permanent memory.

Modifying and Deleting PPP Interfaces

To modify a PPP interface, display the PPP Configuration page and click

in the Action(s)

column for the interface you want to modify. The PPP Interface – Modify page displays, as shown

in Figure 40.

Figure 39. PPP Interface – Modify{ XE "PPP Interface – Modify page" }{ XE "Pages:PPP Interface -

Modify" }

You can change only the status of the PPP connection, the security protocol, your login name,

and your password. To modify the other settings, you must delete the interface and create a new

one.

To delete a PPP interface, display the PPP Configuration page and click

in the Action(s)

column for the interface you want to delete. You should not delete a PPP interface unless you

have received instructions to do so from your ISP. Without an appropriately defined PPP interface,

you will not be able to connect to your ISP. You can recreate the PPP interface with the same

name at a later time.

After modifying or deleting a PPP interface, click

. Then, Click the Admin tab, click

Commit & Reboot

in the task bar, and click

to save your changes to permanent

memory.
