Specify an IPv6 Internet Connection
The modem supports different types of IPv6 Internet connections for which you can specify the settings
manually.
IPv6 Internet Connections and IPv6 Addresses
The modem can support an IPv6 Internet connection through the following connection types:
•
6to4 tunnel. For more information, see
Set Up an IPv6 6to4 Tunnel Internet Connection
•
Pass-through. For more information, see
Set Up an IPv6 Pass Through Internet Connection
on page
49.
•
Fixed. For more information, see
Set Up an IPv6 Fixed Internet Connection
•
Auto Config. For more information, see
Use Auto Config for an IPv6 Internet Connection
on page 51.
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
on page 47).
•
If your Internet connection does not use pass-through or a fixed IP address but is IPv6, use the Auto
Config connection type, which lets the modem autoconfigure its IPv6 connection (see
for an IPv6 Internet Connection
on page 51).
When you enable IPv6 and select any connection type other than IPv6 pass-through, the modem starts the
stateful packet inspection (SPI) firewall function on the DSL interface. The modem creates connection
records and checks every inbound IPv6 packet. If the inbound packet is not destined to the modem itself
and the modem does not expect to receive such a packet, or the packet is not in the connection record, the
modem blocks this packet. This function works in two modes: In secured mode, the modem inspects both
TCP and UDP packets. In open mode, the modem 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 an IPv6 6to4 Tunnel Internet Connection
The remote relay router is the device to which your modem creates a 6to4 tunnel. Make sure that the IPv4
Internet connection is working before you apply the 6to4 tunnel settings for the IPv6 connection.
To set up an IPv6 Internet connection by using a 6to4 tunnel:
1.
Launch a web browser from a computer that is connected to the network.
2.
Enter http://www.routerlogin.net.
