LABEL DESCRIPTION
General
Interface Select this to activate the WAN configuration settings.
Enable
Name Specify a descriptive name for this connection.
Type Select whether it is ADSL/VDSL over PTM, ADSL over ATM, or Ethernet connection.
• ADSL/VDSL over PTM: The SBG uses the VDSL technology for data transmission over the DSL
port.
• ADSL over ATM: The SBG uses the ADSL technology for data transmission over the DSL port.
• Ethernet: The SBG transmits data over the Ethernet WAN port. Select this if you have a DSL
router or modem in your network already.
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.
• PPP over Ethernet (PPPoE): PPPoE (Point to Point Protocol over Ethernet) provides access
control and billing functionality in a manner similar to dial-up services using PPP. Select this if
you have a username and password for Internet access.
• IP over Ethernet (IPoE): In this type of Internet connection, IP packets are routed between the
Ethernet interface and the WAN interface and then formatted so that they can be
understood in a bridged environment.
• PPP over ATM (PPPoA): PPPoA allows just one PPPoA connection over a PVC.
• IP over ATM (IPoA): IPoA allows just one RFC 1483 routing connection over a PVC.
If your connection type is ADSL/VDSL over PTM or Ethernet, 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 SBG to run IPv4 only.
Select IPv4 IPv6 Dualstack to allow the SBG to run IPv4 and IPv6 at the same time.
Select IPv6 Only if you want the SBG to run IPv6 only.
PPP Information This is available only when you select PPPoE or PPPoA in the Encapsulation field.
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.
Password Enter the password associated with the user name above. Click Password Unmask to view the
password you entered.
Connection Select Auto Connect if you do not want the connection to time out. Select On Demand to
Trigger specify the time of idle before the connection times out.
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.
PPPoE This field is available when you select PPPoE encapsulation.
Passthrough
In addition to the SBG'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 SBG. 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.
