If your ISP did not provide details, use the 6to4 tunnel connection type (see 
 on page 37).
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 
34).
If your Internet connection does not use pass-through, a fixed IP address, DHCP, 6rd, or PPPoE but is IPv6,
use the Auto Config connection type, which lets the router autoconfigure its IPv6 connection (see 
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
