Auto Detect Fields
In the IPv6 screen, when you select Auto Detect from the drop-down list, the following
screen displays.
The Connection Type field indicates the connection type detected. The following fields are
also included in this screen:
IPv6 LAN Setup
Router's IPv6 Address on WAN. The IPv6 address acquired for the router's WAN (or
Internet) interface. The number after the slash ('/') is the length of the prefix, which is also
roughly indicated by the underline ('_') under the IPv6 address.
Router's IPv6 Address on LAN.
The IPv6 address acquired for the router's LAN interface.
The number after the slash ('/') is the length of the prefix, which is also roughly indicated by
the underline ('_') under the IPv6 address.
IP Address Assignment.
You can select how you want to assign IPv6 address to the
devices on your home network (the LAN). You can select either DHCP Server or Auto
Config to assign an IPv6 address. Using DHCP Server might pass more information to LAN
devices, but some IPv6 systems might not support the DHCv6 client function. Auto Config is
selected by default.
Use This Interface ID.
You can enable this option and specify the interface ID that you want
for the IPv6 address for the router's LAN interface. If you do not specify an ID here, the router
generates one automatically from its MAC address.

When the connection type is not IPv6 Pass Through or Disabled, the router starts the SPI
firewall function on the WAN interface. The router creates connection records and checks
every inbound IPv6 packet. If the inbound packet is not destined to the router itself and the
router does expect to receive such a packet, or the packet is not in the connection record, the
