Which connection type you must use depends on your IPv6 ISP. Follow the directions that
your IPv6 ISP gave you.
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 an IPv6 6to4 Tunnel Connection
With an IPv6 connection, your modem router creates a 6to4 tunnel to a remote relay router.
Make sure that the IPv4 Internet connection is working before you apply the 6to4 tunnel
settings for the IPv6 connection.
Note: Follow the directions that your IPv6 ISP gave you.
To set up an IPv6 Internet connection by using a 6to4 tunnel:
1. Launch an Internet browser from a computer or WiFi device that is connected to the
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
3. Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
4. Click the OK button.
The BASIC Home screen displays.
