AC1600 WiFi VDSL/ADSL Modem Router Model D6400 
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 
If you are not sure what type of IPv6 connection the modem router uses, use the Auto 
Detect connection type, which lets the modem router detect the IPv6 type that is in use 
(see 
If your Internet connection does not use PPPoE, DHCP, a fixed IP address, or 
pass-through but is IPv6, use the Auto Config connection type, which lets the modem 
router autoconfigure its IPv6 connection (see 
86).
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 Connection Through Auto Detect
If you are not sure what type of IPv6 connection the modem router uses, use the Auto Detect 
connection type, which lets the modem router detect the IPv6 type that is in use.
To set up an IPv6 Internet connection through auto detection:
1. 
Launch a web browser from a computer or WiFi device that is connected to the network.
2. 
Type http://www.routerlogin.net.
A login window opens.
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.
