Tunnel (This is available only when you select
IPv4 Only
or
IPv6 Only
in the
IPv6/IPv4 Mode
field.)
The DS-Lite (Dual Stack Lite) fields display when you set the
IPv6/IPv4 Mode
field to
IPv6 Only
.
Enable Dual Stack Lite to let local computers use IPv4 through an ISP’s IPv6 network. See
Dual Stack Lite on
page 69
for more information.
The 6RD (IPv6 rapid deployment) fields display when you set the
IPv6/IPv4 Mode
field to
IPv4 Only
. See
IPv6 Rapid Deployment on page 69
for more information.
Enable DS-Lite
This is available only when you select
IPv6 Only
in the
IPv6/IPv4 Mode
field. Select
Enable
to let local computers use IPv4 through an ISP’s IPv6 network.
DS-Lite Relay
Server IP
Specify the transition router’s IPv6 address.
Enable 6RD
This is available only when you select
IPv4 Only
in the
IPv6/IPv4 Mode
field. Select
Enable
to tunnel IPv6 traffic from the local network through the ISP’s IPv4 network.
6RD Type
Select
Static
if you have the IPv4 address of the relay server, otherwise select
DHCP
to
have the Device detect it automatically through DHCP.
IPv4 Mask
Length
Enter the subnet mask number (1~32) for the IPv4 network.
6RD Border
Relay Server IP
When you set the
6RD Type
to
Static
, specify the relay server’s IPv4 address in this field.
6RD IPv6 Prefix
Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP’s border relay router and connecting
to the native IPv6 Internet.
IPv6 Address (This is available only when you select
IPv6/IPv4 DualStack
or
IPv6 Only
in the
IPv6/IPv4
Mode
field.)
IPv6 Address
Select
Automatic
if you want to have the Device use the IPv6 prefix from the connected
router’s Router Advertisement (RA) to generate an IPv6 address.
Select
Get IPv6 Address From DHCPv6 Server(IA_NA)
if you want to obtain an IPv6
address from a DHCPv6 server. The IP address assigned by a DHCPv6 server has priority
over the IP address automatically generated by the Device using the IPv6 prefix from an
RA. This option is available only when you choose to get your IPv6 address
automatically.
Select
Prefix Delegation(IA_PD)
to use DHCP PD (Prefix Delegation) which enables
the Device to pass the IPv6 prefix information to its LAN hosts. The hosts can then use
the prefix to generate their IPv6 addresses.
Select
Static
if you have a fixed IPv6 address assigned by your ISP.
Select
None
to not assign any IPv6 address to this WAN connection.
Prefix
Length
Enter the address prefix length to specify how many most significant bits in an IPv6 address
compose the network address.
Next Hop
Enter the IP address of the next-hop gateway. The gateway is a router or switch on the
same segment as your Device's interface(s). The gateway helps forward packets to their
destinations.
IPv6 Routing Feature (This is available only when you select
IPv6/IPv4 DualStack
or
IPv6 Only
in the
IPv6/IPv4 Mode
field. You can enable IPv6 routing features in the following section.)
MLD Proxy
Enable
Select this checkbox to have the Device act as an MLD proxy on this connection. This allows
the Device to get subscription 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.
IPv6 DNS
Server
Configure the IPv6 DNS server in the following section.

Network Setting > Broadband
screen or the
Edit
icon
next to the connection you want to configure. Select
Bridge
as the encapsulation mode. The screen
varies depending on the interface type you select.
If you select
ADSL/VDSL over PTM
as the interface type, the following screen appears.
IPv6 DNS
Select
Dynamic
to have the Device get the IPv6 DNS server addresses from the ISP
automatically.
Select
Static
to have the Device use the IPv6 DNS server addresses you configure
manually.
IPv6 DNS
Server 1
Enter the first IPv6 DNS server address assigned by the ISP.
IPv6 DNS
Server 2
Enter the second IPv6 DNS server address assigned by the ISP.
VLAN (These fields appear when the
Type
is set to
ADSL/VDSL over PTM
.)
Active
Select this to enable VLAN on this WAN interface.
802.1p
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame
that contains bits to define class of service.
Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic through this connection.
The greater the number, the higher the priority level.
802.1q
Type the VLAN ID number (from 1 to 4094) for traffic through this connection.
QoS
Rate Limit
Enter the rate limit for the connection. This is the maximum transmission rate allowed for
traffic on this connection.
WAN Outgoing
Default Tag
Select
Enable
and enter a
DSCP
(DiffServ Code Point) value to have the Device add it in the
packets sent by this WAN interface.
802.1p
This field displays if you activate VLAN for this WAN interface. Enter a priority level (from 0
to 7) to have the Device add it to traffic through this connection.
DSCP
If you enable Select
WAN Outgoing Default Tag
, enter a
DSCP
(DiffServ Code Point)
value to have the Device add it in the packets sent by this WAN interface.
MTU
MTU Size
Enter the MTU (Maximum Transfer Unit) size for this traffic.
Bridging and
Routing in the
same WAN
Use this feature to bridge a LAN port(s) with the WAN interface. Traffic to/from LAN ports
not in the bridge is routed from the WAN interface.
ADSL use same VPI/VCI in Bridge and Route modes.
VDSL use same VLAN in Bridge and Route modes.
Enable Con-
current WAN
Enable this if you want to use the same VPI/VCI settings in different WAN interfaces. Select
this and then choose the ports to bridge with the WAN interface. \
ADSL concurrent WAN uses the same VCI/PVI in both routing and bridge modes.
VDSL concurrent WAN uses same VLAN in both routing and bridge mode.
