AC1200 WiFi DSL Modem Router—Essentials Edition Model D6100

Pass-through. For more information, see Set Up an IPv6 Pass-Through Connection on page 63.

Fixed. For more information, see Set Up an IPv6 Fixed Connection on page 64.

DHCP. For more information, see Set Up an IPv6 DHCP Connection on page 66.

PPP over Ethernet. For more information, see Set Up an IPv6 PPPoE Connection on page 68.

Which connection type you must use depends on your IPv6 ISP. Follow the directions that your IPv6 ISP gave you.

If your ISP did not provide details, use the 6to4 tunnel connection type (see Set Up an IPv6 6to4 Tunnel Connection on page 61).

If you are not sure what type of IPv6 connection the modem router uses, use the Auto Detect connection type, which lets the modem router detect the IPv6 type that is in use (see Set Up and IPv6 Connection Through Auto Detect on page 57).

If your Internet connection does not use PPPoE, DHCP, a fixed IP address, or pass-through but is IPv6, use the Auto Config connection type, which lets the modem router autoconfigure its IPv6 connection (see Set Up and IPv6 Connection Through Auto Config on page 59).

When you enable IPv6 and select any connection type other than IPv6 pass-through, the modem router starts the stateful packet inspection (SPI) firewall function on the WAN interface. The modem router creates connection records and checks every inbound IPv6 packet. If the inbound packet is not destined to the modem router itself and the modem router does not expect to receive such a packet, or the packet is not in the connection record, the modem router blocks this packet. This function works in two modes: In secured mode, the modem router inspects both TCP and UDP packets. In open mode, the modem router inspects UDP packets only.

IPv6 addresses are denoted by eight groups of hexadecimal quartets that are separated by colons. You can reduce any four-digit group of zeros within an IPv6 address to a single zero or omit it. The following errors invalidate an IPv6 address:

More than eight groups of hexadecimal quartets

More than four hexadecimal characters in a quartet

More than two colons in a row

Set Up and IPv6 Connection Through Auto Detect

If you are not sure what type of IPv6 connection the modem router uses, use the Auto Detect connection type, which lets the modem router detect the IPv6 type that is in use.

To set up an IPv6 Internet connection through auto detection:

1.Launch an Internet browser from a computer or WiFi device that is connected to the network.

2.Type http://www.routerlogin.net. A login screen displays.
