Add/Edit Internet Connection
Click
Add New WAN Interface
in the
Broadband
screen or the
Edit
icon next to an existing WAN
interface to configure a WAN connection. The screen varies depending on the interface type, mode,
encapsulation, and IPv6/IPv4 mode you select.
6.2.1.1
Routing Mode
Use
Routing
mode if your ISP give you one IP address only and you want multiple computers to
share an Internet account.
The following example screen displays when you select the
ADSL/VDSL over ATM
connection
type,
Routing
mode, and
PPPoE
encapsulation. The screen varies when you select other interface
type, encapsulation, and IPv6/IPv4 mode.

DESCRIPTION
General
Active
Select this to enable the interface.
Name
Specify a descriptive name for this connection.
Type
Select whether it is an ADSL/VDSL over PTM, ADSL over ATM connection or Ethernet.
Mode
Select
Routing
if your ISP give you one IP address only and you want multiple computers to
share an Internet account.
Encapsulation
Select the method of encapsulation used by your ISP from the drop-down list box. This
option is available only when you select
Routing
in the
Mode
field.
The choices depend on the connection type you selected. If your connection type is
ADSL/
VDSL over PTM
, the choices are
PPPoE
and
IPoE
. If your connection type is
ADSL over
ATM
, the choices are
PPPoE
,
PPPoA
,
IPoE
and
IPoA
.
IPv6/IPv4 Mode
Select
IPv4 Only
if you want the Device to run IPv4 only.
Select
IPv6/IPv4 DualStack
to allow the Device to run IPv4 and IPv6 at the same time.
Select
IPv6 Only
if you want the Device to run IPv6 only.
ATM PVC Configuration (These fields appear when the
Type
is set to
ADSL over ATM
.)
VPI
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
VCI
The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM
traffic). Enter the VCI assigned to you.
DSL Link Type
The choices in this field change according to the
Encapsulation
method chosen above. This
field is not editable.
PPPoA
and
IPoA
encapsulation use the same named
DSL Link Type
.
Ethernet-over-ATM (
EoA
) is used for
PPPoE
, and
IPoE
encapsulation.
EoA
a
protocol for data transfer between Ethernet LAN and WAN over the ATM protocol. It
creates a bridged connection between the Device and the ISP. It uses an Ethernet header in
the packet, so that you can have multiple services/connections over one PVC. You can set
each connection to have its own MAC address or all connections share one MAC address but
use different VLAN IDs for different services. EoA supports ENET ENCAP (IPoE), PPPoE and
RFC1483/2684 bridging encapsulation methods.
PPPoA
(PPP over ATM) allows just one PPPoA connection over a PVC.
IPoA
(IP over ATM) allows just one RFC 1483 routing connection over a PVC.
Encapsulation
Mode
Select the method of multiplexing used by your ISP from the drop-down list box. Choices
are:
•
LLC/SNAP-BRIDGING:
In LCC encapsulation, bridged PDUs are encapsulated by
identifying the type of the bridged media in the SNAP header. This is available only when
you select
IPoE
or
PPPoE
in the
Select DSL Link Type
field.
•
VC/MUX:
In VC multiplexing, each protocol is carried on a single ATM virtual circuit
(VC). To transport multiple protocols, the Device needs separate VCs. There is a binding
between a VC and the type of the network protocol carried on the VC. This reduces
payload overhead since there is no need to carry protocol information in each Protocol
Data Unit (PDU) payload.
•
LLC/ENCAPSULATION:
More than one protocol can be carried over the same VC. This
is available only when you select
PPPoA
in the
Encapsulation
field.
•
LLC/SNAP-ROUTING:
In LCC encapsulation, an IEEE 802.2 Logical Link Control (LLC)
header is prefixed to each routed PDU to identify the PDUs. The LCC header can be
followed by an IEEE 802.1a SubNetwork Attachment Point (SNAP) header. This is
available only when you select
IPoA
in the
Encapsulation
field.

such as e-mail.
Select
CBR
(Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or data
traffic.
Select
Non Realtime VBR
(non real-time Variable Bit Rate) for connections that do not
require closely controlled delay and delay variation.
Select
Realtime VBR
(real-time Variable Bit Rate) for applications with bursty connections
that require closely controlled delay and delay variation.
PPP Information (This is available only when you select
PPPoE
or
PPPoA
in the
Mode
field.)
PPP User Name
Enter the user name exactly as your ISP assigned. If assigned a name in the form
user@domain
where domain identifies a service name, then enter both components exactly
as given.
PPP Password
Enter the password associated with the user name above. Select
password unmask
to
show your entered password in plain text.
PPP Trigger
Type
Select when to have the Device establish the PPP connection.
Auto Connect
- select this to not let the connection time out.
Connect on Demand
- select this to automatically bring up the connection when the
Device receives packets destined for the Internet.
Manual
- select this if you want to manually trigger the connection up.
Authentication
Method
Select an authentication protocol for outgoing connection requests through this WAN
interface.
PAP
- Password Authentication Protocol (PAP) authentication sends user name and
password in clear text without using encryption. Select this if your Device accepts PAP only.
CHAP
- Challenge Handshake Authentication Protocol (CHAP) provides authentication
through a shared secret key and uses a three way handshake. Select this if your Device
accepts CHAP only.
MSCHAP
- Microsoft CHAP provides authentication through a shared secret key and uses a
three way handshake. It provides improved usability with Microsoft products. Select this if
your Device accepts MSCHAP only.
AUTO
- Select this if your Device accepts either PAP, CHAP, or MSCHAP authentication
method.
Idle Timeout
This value specifies the time in minutes that elapses before the router automatically
disconnects from the PPPoE server.
This field is not configurable if you select
Auto Connect
in the
PPP Trigger Type
field.
PPPoE Service
Name
Enter the name of your PPPoE service here.
PPPoE
Passthrough
This field is available when you select
PPPoE
encapsulation.
In addition to the Device’s built-in PPPoE client, you can enable PPPoE pass through to allow
up to ten hosts on the LAN to use PPPoE client software on their computers to connect to the
ISP via the Device. Each host can have a separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for application where NAT is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use PPPoE client
software on their computers to connect to the ISP.
IP Address (This is available only when you select
IPv4 Only
or
IPv6/IPv4 DualStack
in the
IPv6/IPv4
Mode
field.)

A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is not fixed;
the ISP assigns you a different one each time you connect to the Internet. Select this if you
have a dynamic IP address.

Enable
Select this option to enable full cone NAT on this connection. This field is available only when
you activate NAT. In full cone NAT, the Device maps all outgoing packets from an internal IP
address and port to a single IP address and port on the external network. The Device also
maps packets coming to that external IP address and port to the internal IP address and
port.
IGMP Proxy
Enable
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data.
Select this option to have the Device act as an IGMP proxy on this connection. This allows
the Device to get subscribing information and maintain a joined member list for each
multicast group. It can reduce multicast traffic significantly.
Apply as
Default
Gateway
Select this option to have the Device use the WAN interface of this connection as the system
default gateway.
