Specify an IPv6 Internet Connection The router suppor

ts many different types of IPv6 Internet connections for which you can specify the settings manually.
IPv6 Internet Connections and IPv6 Addresses
The router can support an IPv6 Internet connection through the following connection types:
• A

uto Detect
. For more information, see Use Auto Detect for an IPv6 Internet Connection on page 34.
• A
uto Config. For more information, see Use Auto Config for an IPv6 Internet Connection on page 36.
• 6to4 tunnel
. For more information, see Set Up an IPv6 6to4 Tunnel Internet Connection on page 37.
• P
ass-through. For more information, see Set Up an IPv6 Pass Through Internet Connection on page 39.
• Fix

ed. For more information, see Set Up an IPv6 Fixed Internet Connection on page 39.
• DHCP
. For more information, see Set Up an IPv6 DHCP Internet Connection on page 41.
• 6rd
. For more information, see Set Up an IPv6 6rd Tunnel Connection on page 43.
• PPP
oE
. For more information, see Set Up an IPv6 PPPoE Internet Connection on page 45.
Which connection type you must use depends on your IPv6 ISP. Follow the directions that your IPv6 ISP gave you. Specify Your Internet Settings
33
Nighthawk AC1900 Smart WiFi Router Model R6900 
						

							•
If your ISP did not provide details, use the 6to4 tunnel connection type (see Set Up an IPv6 6to4 Tunnel Internet
Connection on page 37).
• If y
ou 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 Use Auto Detect for an IPv6 Internet Connection on page
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 Use Auto
Config f
or an IPv6 Internet Connection on page 36).
When y

ou 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
e

very inbound IPv6 packet. If the inbound packet is not destined to the router itself and the 
router does not expect
to receiv
e 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 pac
kets 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
Use Auto Detect for an IPv6 Internet Connection To set up an IPv6 Internet connection through auto detection: 1.

• Connection Type
. This field indicates the connection type that is detected.
• Router’s IPv6 Address on WAN. This field shows the IPv6 address that is acquired for the 
router’s WAN
(or Inter
net) interface. The number after the slash (/) is the length of the prefix, which is also i\
ndicated by
the underline (_) under the IPv6 address. If no address is acquired, the field displays Not Available.
• Router’s IPv6 Address on LAN. This field shows the IPv6 address that is acquired for the router’s LAN
interf

ace. The number after the slash (/) is the length of the prefix, which is also i\
ndicated by the underline
(_) under the IPv6 address. If no address is acquired, the field displays Not Available.
6. Select an IP Address Assignment radio button:
•Use DHCP Server. This method passes more information to LAN devices but some IPv6 systems might not
support the DHCv6 client function.
• Auto Config. This is the default setting.
This setting specifies ho
