of the prefix, which is also indicated by the underline (_) under the IPv6 address. If no
address is acquired, the field displays Not Available.
•
Router's IPv6 Address on LAN. 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.
3.
(Optional) In the User Class (If Required) field, enter a host name.
Most people do not need to change this field, but if your ISP has given you a specific host
name, enter it here.
4.
(Optional) In the DHCP Domain Name (If Required) field, enter a domain name.
You can type the domain name of your IPv6 ISP. (Do not enter the domain name for the
IPv4 ISP here.) For example, if your ISP mail server is mail.xxx.yyy.zzz, you would type
xxx.yyy.zzz as the domain name. If your ISP provided a domain name, type it in this field.
(For example, Earthlink Cable might require a host name of home, and Comcast
sometimes supplies a domain name.)
5.
Specify how the router assigns IPv6 addresses to the devices on your home network (the
LAN) by selecting one of the following radio buttons:
•
Use DHCP Server. This method passes more information to LAN devices, but some
IPv6 systems might not support the DHCv6 client function.
•
Auto Config. This is the default setting.
6.
(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 router's LAN interface.
If you do not specify an ID here, the router generates one automatically from its MAC
address.
7.
Specify IPv6 filtering.
When the connection type is not IPv6 Pass Through or Disabled, the router starts the
stateful packet inspection (SPI) firewall function on the WAN interface. The router creates
connection records and checks every inbound IPv6 packet. The router blocks this packet
when the inbound packet is not destined to the router itself and the router does not expect
to receive such a packet. The router also blocks this packet when the packet is not in the
connection record. This function has two modes.
Specify the mode by selecting one of the following radio buttons:
•
Secured. In the secured mode, which is the default mode, the router inspects both
TCP and UDP packets.
•
Open. In the open mode, the router inspects UDP packets only.
