Table 30 Network Setting > Broadband > Add/Edit New WAN Interface (Routing Mode)
LABEL
DESCRIPTION
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. If your connection type is Ethernet, the choices are PPPoE and
IPoE.
IPv4/IPv6 Mode
Select IPv4 Only if you want the Zyxel Device to run IPv4 only.
Select IPv4 IPv6 DualStack to allow the Zyxel Device to run IPv4 and IPv6 at the same time.
Select IPv6 Only if you want the Zyxel Device to run IPv6 only.
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 Connection
Select when to have the Zyxel Device establish the PPP connection.
Trigger
Auto Connect - select this to not let the connection time out.
On Demand - select this to automatically bring up the connection when the Zyxel Device
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 available if you select Auto Connect in the PPP Connection Trigger field.
PPPoE
This field is available when you select PPPoE encapsulation.
Passthrough
In addition to the Zyxel 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 Zyxel 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.
ATM PVC Configuration (These fields appear when the Type is set to ADSL over ATM.)
VPI [0-255]
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
VCI [32-65535]
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. 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 Zyxel 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.
