IPv6 LAN Setup
Link Local Address
Type
Select
Manual
to manually enter a link local address. Select
EUI64
to use the EUI-64
format to generate a link local address from the Ethernet MAC address.
IPv6 Address
If you selected
Manual
in the
Link Local Address Type
field, enter the LAN IPv6
address you want to assign to your Device in hexadecimal notation, for example,
fe80::1 (factory default).
Prefix
Enter the address prefix to specify how many most significant bits in an IPv6 address
compose the network address.
MLD Snooping
Multicast Listener Discovery (MLD) allows an IPv6 switch or router to discover the
presence of MLD hosts who wish to receive multicast packets and the IP addresses of
multicast groups the hosts want to join on its network.
Select
Enabled
to activate
MLD Snooping on the Device. This allows the Device to check MLD packets passing
through it and learn the multicast group membership. It helps reduce multicast traffic.
Lan Global Identifier
Type
Select
Manual
to manually enter a LAN Identifier as the interface ID to identify the
LAN interface.
The LAN Identifier is appended to the IPv6 address prefix to create the
routable global IPv6 address. Select
EUI64
to use the EUI-64 format to generate an
interface ID from the Ethernet MAC address.
Lan Identifier
If you selected
Manual
, enter the LAN Identifier in this field. The LAN identifier should
be unique and 64 bits in hexadecimal form. Every 16 bit block should be separated by
a colon as in XXXX:XXXX:XXXX:XXXX where X is a hexadecimal character. Blocks of
zeros can be represented with double colons as in XXXX:XXXX::XXXX.
LAN IPv6 Address Setting
Delegate prefix from
WAN
Select this option to automatically obtain an IPv6 network prefix from the service
provider or an uplink router.

Select this option to configure a fixed IPv6 address for the Device’s LAN IPv6 address.
Static IPv6 Address
Prefix
If you select static IPv6 address, enter the IPv6 address prefix that the Device uses for
the LAN IPv6 address.
Prefix length
If you select static IPv6 address, enter the IPv6 prefix length that the Device uses to
generate the LAN IPv6 address.
An IPv6 prefix length
specifies how many most significant bits (starting from the left)
in the address compose the network address. This field displays the bit number of the
IPv6 subnet mask.
Preferred Lifetime
Enter the preferred lifetime for the prefix.
Valid Lifetime
Enter the valid lifetime for the prefix.
RADVD Setup
Send RA on
Select this to have the Device send router advertisement messages to the LAN hosts.
Router advertisement is a response to a router solicitation or a periodical multicast
advertisement from a router to advertise its presence and other parameters, such as
IPv6 prefix and DNS information.
Router solicitation is a request from a host to locate a router that can act as the
default router and forward packets.
Note: The LAN hosts neither generate global IPv6 addresses nor communicate with
other networks if you disable this feature.
Delegate M/O flag
from WAN
Select this to have the Device obtain the M/O (Managed/Other) flag setting from the
service provider or uplink router.
Manual
Select this to specify the M/O flag setting manually.

on
Select this to have the Device indicate to hosts to obtain DNS information through
DHCPv6.
Clear this to have the Device indicate to hosts that DNS information is not available in
this network.
Advertisement
interval option on
Select this to have the Router Advertisement messages the VDSL Router
sends specify the allowed interval between Router Advertisement messages.
Hop limit
Enter the maximum number of network segments that a packet can cross before
reaching the destination. When forwarding an IPv6 packet, IPv6 routers are required
to decrease the Hop Limit by 1 and to discard the IPv6 packet when the Hop Limit is 0.
Possible value for this field are 0-255.
Router Lifetime
Enter the time in seconds that hosts should consider the Device to be the default
router. Possible values for this field are 0-9000.
Router Preference
Select the router preference (
Low
,
Medium
or
High
) for the Device. The Device
sends this preference in the router advertisements to tell hosts what preference they
should use for the Device. This helps hosts to choose their default router especially
when there are multiple IPv6 router in the network.
Note: Make sure the hosts also support router preference to make this function work.
Reachable Time (ms)
Enter the time in milliseconds that can elapse before a neighbor is detected. Possible
values for this field are 0-3600000.
Retrans Timer (ms)
Enter the time in milliseconds between neighbor solicitation packet retransmissions.
Possible values for this field are 1000-4294967295.
RA Interval
Enter the time in seconds between router advertisement messages. Possible values for
this field are 4-1800.
Delegate MTU from
WAN
Select this to have the Device obtain the MTU setting from the service provider or
uplink router.
Manual
Select this to specify the MTU manually.
MTU
The Maximum Transmission Unit. Type the maximum size of each IPv6 data packet, in
bytes, that can move through this interface. If a larger packet arrives, the Device
divides it into smaller fragments.
DAD attempts
Specify the number of DAD (Duplicate Address Detection) attempts before an IPv6
address is assigned to the Device LAN interface. Possible values for this field are 1-7.
DHCPv6
DHCPv6 Server
Use this field to
Enable
or
Disable
DHCPv6 server on the Device.
DNSv6 Mode
Select the DNS role (
Proxy
or
Relay
) that you want the Device to act in the IPv6 LAN
network. Alternatively, select Manual and specify the DNS servers’ IPv6 address in the
fields below.
Primary DNS
This field is available if you choose
Manual
as the DNSv6 mode. Enter the first DNS
server IPv6 address the Device passes to the DHCP clients.
Secondary DNS
This field is available if you choose
Manual
as the DNSv6 mode. Enter the second DNS
server IPv6 address the Device passes to the DHCP clients.
Information refresh
time
Enter the number of seconds a DHCPv6 client should wait before refreshing
information retrieved from DHCPv6.

File Sharing Overview
6.7.1
What You Need to Know
Workgroup name
This is the name given to a set of computers that are connected on a network and share resources
such as a printer or files. Windows automatically assigns the workgroup name when you set up a
network.
Shares
When settings are set to default, each USB device connected to the Device is given a folder, called
a “share”. If a USB hard drive connected to the Device has more than one partition, then each
partition will be allocated a share. You can also configure a “share” to be a sub-folder or file on the
USB device.
File Systems
A file system is a way of storing and organizing files on your hard drive and storage device. Often
different operating systems such as Windows or Linux have different file systems. The file-sharing
feature on your Device supports File Allocation Table (FAT) and FAT32 file systems.
Windows/CIFS
Common Internet File System (CIFS) is a standard protocol supported by most operating systems
in order to share files across the network.

CIFS runs over TCP/IP but uses the SMB (Server Message Block) protocol found in Microsoft
Windows for file and printer access; therefore, CIFS will allow all applications, not just Web
browsers, to open and share files across the Internet.
The Device uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS
compatible computers can access the USB file storage devices connected to the Device. CIFS
protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to
your systems specifications for CIFS compatibility).
NFS
Network File System (NFS) is a protocol most commonly used on Unix-like systems in order to
share files across the network.
Samba
SMB is a client-server protocol used by Microsoft Windows systems for sharing files, printers, and
so on.
Samba is a free SMB server that runs on most Unix and Unix-like systems. It provides an
implementation of an SMB client and server for use with non-Microsoft operating systems.
File Transfer Protocol
This is a method of transferring data from one computer to another over a network such as the
Internet.
6.7.2
Before You Begin
Make sure the Device is connected to your network and turned on.
1
Connect the USB device to one of the Device’s USB ports. Make sure the Device is connected to
your network.
2
The Device detects the USB device and makes its contents available for browsing. If you are
connecting a USB hard drive that comes with an external power supply, make sure it is connected
to an appropriate power source that is on.
Note: If your USB device cannot be detected by the Device, try disconnecting and
reconnecting it.
