LABEL DESCRIPTION
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
page 70 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 70
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 Specify the transition router's IPv6 address.
Server IP
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 Enter the subnet mask number (1~32) for the IPv4 network.
Length
6RD Border When you set the 6RD Type to Static, specify the relay server's IPv4 address in this field.
Relay Server IP
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 Enter the address prefix length to specify how many most significant bits in an IPv6 address
Length
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 Select this checkbox to have the Device act as an MLD proxy on this connection. This allows
Enable the Device to get subscription information and maintain a joined member list for each
multicast group. It can reduce multicast traffic significantly.
Apply as Select this option to have the Device use the WAN interface of this connection as the system
Default default gateway.
