LABEL
DESCRIPTION
Interface Group
Group Name
Select the interface group name for which you want to configure LAN settings. See
Chapter
13 on page 201
for how to create a new interface group.
LAN IP Setup
IP Address
Enter the LAN IP address you want to assign to your Device in dotted decimal notation, for
example, 192.168.1.1 (factory default).
Subnet Mask
Type the subnet mask of your network in dotted decimal notation, for example
255.255.255.0 (factory default). Your Device automatically computes the subnet mask
based on the IP Address you enter, so do not change this field unless you are instructed to
do so.
IGMP Snooping
Status
Select the
Enable IGMP Snooping
checkbox to allows the Device to passively learn
multicast group.
IGMP Mode
Select
Standard Mode
to have the Device forward multicast packets to a port that joins the
multicast group and broadcast unknown multicast packets from the WAN to all LAN ports.
Select
Blocking Mode
to have the Device block all unknown multicast packets from the
WAN.
DHCP Server State
DHCP
Select
Enable
to have the Device act as a DHCP server or DHCP relay agent.
Select
Disable
to stop the DHCP server on the Device.
Select
DHCP Relay
to have the Device forward DHCP request to the DHCP server.

DHCP Relay
Server Address
This field is only available when you select
DHCP Relay
in the
DHCP
field.
IP Address
Enter the IP address of the actual remote DHCP server in this field.
IP Addressing
Values
This field is only available when you select
Enable
in the
DHCP
field.
Beginning IP
Address
This field specifies the first of the contiguous addresses in the IP address pool.
Ending IP
Address
This field specifies the last of the contiguous addresses in the IP address pool.
DHCP Server
Lease Time
This is the period of time DHCP-assigned addresses is used. DHCP automatically assigns IP
addresses to clients when they log in. DHCP centralizes IP address management on central
computers that run the DHCP server program. DHCP leases addresses, for a period of time,
which means that past addresses are “recycled” and made available for future reassignment
to other systems.
This field is only available when you select
Enable
in the
DHCP
field.
Days/Hours/
Minutes
Enter the lease time of the DHCP server.
DNS Values
This field is only available when you select
Enable
in the
DHCP
field.
DNS
Select the type of service that you are registered for from your Dynamic DNS service
provider.
Select
Dynamic
if you have the Dynamic DNS service.
Select
Static
if you have the Static DNS service.
DNS Server 1
DNS Server 2
Enter the first and second DNS (Domain Name System) server IP address the Device passes
to the DHCP clients.
LAN IPv6 Mode Setup
IPv6 State
Select
Enable
to activate the IPv6 mode and configure IPv6 settings on the Device.
LAN IPv6 Address Setup
Delegate prefix
from WAN
Select this option to automatically obtain an IPv6 network prefix from the service provider
or an uplink router.
Static
Select this option to configure a fixed IPv6 address for the Device’s LAN IPv6 address.
ULA IPv6 Address Setup
IPv6 Address
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.
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
Enable MLD Snooping
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.

The Static DHCP Screen
This table allows you to assign IP addresses on the LAN to specific individual computers based on
their MAC Addresses.
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
Use this screen to change your Device’s static DHCP settings. Click
Network Setting > Home
Networking
> Static DHCP
to open the following screen.
LAN IPv6
Address Assign
Setup
Select how you want to obtain an IPv6 address:
•
stateless + DNS send by RADVD:
The Device uses IPv6 stateless autoconfiguration.
RADVD (Router Advertisement Daemon) is enabled to have the Device send IPv6 prefix
information in router advertisements periodically and in response to router solicitations.
DHCPv6 server is disabled. (See
page 134
for more information on RADVD.)
•
stateless + DNS send by DHCPv6
: The Device uses IPv6 stateless autoconfiguration.
The DNS is provided by a DHCPv6 server.
•
stateful + DHCPv6 server:
The Device uses IPv6 stateful autoconfiguration. The
DHCPv6 server is enabled to have the Device act as a DHCPv6 server and pass IPv6
addresses, DNS server and domain name information to DHCPv6 clients.
•
stateful + DHCPv6 relay:
The Device uses IPv6 stateful autoconfiguration.
DHCPv6
Relay
is enabled to have the Device relay client DHCPv6 requests.
DHCPv6 Configuration
DHCPv6 State
This shows the status of the DHCPv6.
IPv6 DNS Values
IPv6 DNS
Server 1-3
Select
From ISP
if your ISP dynamically assigns IPv6 DNS server information.
Select
User-Defined
if you have the IPv6 address of a DNS server. Enter the DNS server
IPv6 addresses the Device passes to the DHCP clients.
Select
None
if you do not want to configure IPv6 DNS servers.
IPv6 Address Values
IPv6 Start
Address
If DHCPv6 is enabled, specify the first IPv6 address in the pool of addresses that can be
assigned to DHCPv6 clients.
IPv6 End
Address
If DHCPv6 is enabled, specify the last IPv6 address in the pool of addresses that can be
assigned to DHCPv6 clients.
IPv6 Domain
Name
If DHCPv6 is enabled, specify the domain name to be assigned to DHCPv6 clients.
IPv6 Router Advertisement State
RADVD State
This shows the status of RADVD.

Status
This field displays whether the client is connected to the Device.
MAC Address
The MAC (Media Access Control) or Ethernet address on a LAN (Local Area Network) is
unique to your computer (six pairs of hexadecimal notation).
A network interface card such as an Ethernet adapter has a hardwired address that is
assigned at the factory. This address follows an industry standard that ensures no other
adapter has a similar address.
IP Address
This field displays the IP address relative to the # field listed above.

The UPnP Screen
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
See
page 134
for more information on UPnP.
Use the following screen to configure the UPnP settings on your Device. Click
Network Setting >
Home Networking
> UPnP
to display the screen shown next.
Figure 55
Network Setting > Home Networking > UPnP
The following table describes the labels in this screen.
IP Address
If you select
Manual Input
, enter the IP address that you want to assign to the
computer on your LAN with the MAC address that you will also specify.

UPnP
Select

to activate UPnP. Be aware that anyone could use a UPnP application to open
the web configurator's login screen without entering the Device's IP address (although you
must still enter the password to access the web configurator).
UPnP NAT-T
Select
Enable
to allow UPnP-enabled applications to automatically configure the Device so
that they can communicate through the Device by using NAT traversal. UPnP applications
automatically reserve a NAT forwarding port in order to communicate with another UPnP
enabled device; this eliminates the need to manually configure port forwarding for the UPnP
enabled application.
