If your ISP did not provide details, you can select 6to4 Tunnel.

If you are not sure what type of IPv6 connection the modem router uses, select Auto 
Detect so that the modem router detects the IPv6 type that is in use.

If your Internet connection does not use PPPoE, DHCP, a fixed IP address, or 
pass-through but is IPv6, select Auto Config.

For IPv6 address requirements, information about IPv6 filtering, and 
detailed information about IPv6 Internet connection types, see the 
following sections.

Click the Apply button.

Your settings are saved.

IPv6 addresses are denoted by eight groups of hexadecimal quartets that are separated by 
colons. Any four-digit group of zeroes within an IPv6 address can be reduced to a single zero 
or altogether omitted.

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

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 has two modes:

Secured. In secured mode, the modem router inspects both TCP and UDP packets.

Open. In open mode, the modem router inspects UDP packets only.
