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
Internet Connection
• If you are not sure what type of IPv6 connection the router uses, use the Auto Detect connection type,
which lets the router detect the IPv6 type that is in use (see
Connection on page 27).
• If your Internet connection does not use pass-through, a fixed IP address, DHCP, or PPPoE but is IPv6,
use the Auto Config connection type, which lets the router autoconfigure its IPv6 connection (see
Auto Config for an IPv6 Internet Connection
When you enable IPv6 and select any connection type other than IPv6 pass-through, 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. If the inbound packet is not destined to the router itself and the
router does not expect to receive such a packet, or the packet is not in the connection record, the router
blocks this packet. This function works in two modes: In secured mode, the router inspects both TCP and
UDP packets. In open mode, the 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
