The following table describes the labels in this screen.
Table 8 Network Setting > Broadband > Add New WAN Interface/Edit (Routing Mode)
LABEL DESCRIPTION
General
Name Specify a descriptive name for this connection.
Type Select whether it is an ADSL/VDSL over PTM, ADSL over ATM or Ethernet connection.
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.
IPv4/IPv6 Mode Select IPv4 Only if you want the VMG to run IPv4 only.
Select IPv4 IPv6 DualStack to allow the VMG to run IPv4 and IPv6 at the same time.
Select IPv6 Only if you want the VMG to run IPv6 only.
PPP Information (This is available only when you select PPPoE or PPPoA in the Encapsulation 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 Select when to have the VMG establish the PPP connection.
Type
Auto Connect - select this to not let the connection time out.
On Demand - select this to automatically bring up the connection when the VMG receives
packets destined for the Internet.
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 This field is available when you select PPPoE encapsulation.
Passthrough
In addition to the VMG'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 VMG. 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.
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.
Encapsulation 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.
• VC/MUX: In VC multiplexing, each protocol is carried on a single ATM virtual circuit
(VC). To transport multiple protocols, the VMG 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.
