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.
