From the Internet Connection Type menu, select 6rd Tunnel.
The router automatically detects the information in the Router’s IPv6 Address on LAN field. This field shows
the IPv6 address that is acquired for the router’s LAN interface. The number after the slash (/) is the length of
the prefix, which is also indicated by the underline (_) under the IPv6 address. If no address is acquired, the
field displays Not Available.
In the 6rd Configuration section, configure the 6rd settings:
6rd Prefix. Enter the IPv6 prefix that your ISP gave you.
6rd Prefix Length. Enter the IPv6 prefix length that your ISP gave you.
6rd Border Relay Address. Enter the border router’s IPv4 address that your ISP gave you.
6rd Address Mask Length. Enter the IPv4 mask length that your ISP gave you.
Select an IPv6 Domain Name Server (DNS) Address radio button:
Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your ISP automatically
assigns this address.
Use These DNS Servers. If you know that your ISP requires specific servers, select this option. Enter the
IP address of your ISP’s primary DNS server. If a secondary DNS server address is available, enter it also.
Select an IP Address Assignment radio button:
