5. From the Internet Connection Type menu, select 6rd Tunnel.
The page adjusts.
The page adjusts. The modem router automactially detects the information in the following sections:
•6rd (IPv6 Rapid Development) Configuration. The modem router detects the service provider’s
IPv4 network and attempts to establish an IPv6 6rd tunnel connection. If the IPv4 network returns
6rd parameters to the router, the page adjusts to display the correct settings in this section.
•Router’s IPv6 Address on LAN. This field shows the IPv6 address that is acquired for the modem
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.
6. 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.
7. Select an IP Address Assignment radio button:
•Use DHCP Server. This method passes more information to LAN devices but some IPv6 systems
might not support the DHCPv6 client function.
•Auto Config. This is the default setting.
This setting specifies how the modem router assigns IPv6 addresses to the devices on your home
network (the LAN).
8. (Optional) Select the Use This Interface ID check box and specify the interface ID that you want to be
used for the IPv6 address of the modem router’s LAN interface.
If you do not specify an ID here, the modem router generates one automatically from its MAC address.
9. Select an IPv6 Filtering radio button:
•Secured. In secured mode, which is the default mode, the modem router inspects both TCP and
•Open. In open mode, the modem router inspects UDP packets only.
