Overview
This chapter describes how to configure LAN settings.
A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is a computer network limited to the immediate area, usually the same building or
floor of a building.
Figure 74
LAN Example
The LAN screens can help you configure a manage IP address, and partition your physical network
into logical networks.
12.2
What You Can Do
Use the
LAN
IP
screen to configure the IPv4 and IPv6 addresses for your NBG6817 on the LAN
(
Section 12.4 on page 113
).
Use the
Static DHCP
screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (
Section 12.5 on page 114
).
Use the
IPv6 LAN
screen to configure the IPv6 address for your NBG6817 on the LAN (
Section
12.6 on page 115
).
12.3
What You Need To Know
The actual physical connection determines whether the NBG6817 ports are LAN or WAN ports.
There are two separate IP networks, one inside the LAN network and the other outside the WAN
network as shown next.

LAN and WAN IP Addresses
The LAN parameters of the NBG6817 are preset in the factory with the following values:
IPv4 address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
DHCP server enabled with 128 client IPv4 addresses starting from 192.168.1.33.
These parameters should work for the majority of installations.

DESCRIPTION
IP Address
Type the IP address of your NBG6817 in dotted decimal notation.
IP Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your NBG6817
will automatically calculate the subnet mask based on the IP address that you assign.
Unless you are implementing subnetting, use the subnet mask computed by the
NBG6817.

Static DHCP Screen
This screen allows you to assign IP addresses on the LAN to specific individual computers based on
their MAC addresses.
To change your NBG6817’s static DHCP settings, click
Expert Mode
> LAN > Static DHCP
.
Figure 77
Expert Mode > LAN > Static DHCP
The following table describes the labels on this screen.
DHCP Server
Select
Enable
to activate DHCP for LAN.
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (computers) to obtain TCP/IP configuration at startup from a server.
Enable the DHCP server unless your ISP instructs you to do otherwise. Select
Disable
to stop the NBG6817 acting as a DHCP server. When configured as a server, the
NBG6817 provides TCP/IP configuration for the clients. If not, DHCP service is
disabled and you must have another DHCP server on your LAN, or else the computers
must be manually configured. When set as a server, fill in the following four fields.
IP Pool Starting
Address
This field specifies the first of the contiguous addresses in the IP address pool for LAN.
Pool Size
This field specifies the size, or count of the IP address pool for LAN.

LAN IPv6 Address Assignment
Enable_DHCPv6-PD
Select this option to use DHCPv6 prefix delegation. The NBG6817 will obtain an IPv6 prefix from the ISP or a
connected uplink router for the LAN.
Autoconfiguration
Type
Select
SLAAC + RDNSS
to enable IPv6 stateless auto-configuration on this interface.
The interface will generate an IPv6 IP address itself from a prefix obtained from an IPv6
router in the network.
Select
SLAAC + Stateless DHCPv6
to enable IPv6 stateless auto-configuration on this
interface. The interface will get an IPv6 address from an IPv6 router and the DHCP
server. The IP address information gets through DHCPv6.
Select
Stateful DHCPv6
to
allow a DHCP server to assign and pass IPv6 network
addresses, prefixes and other configuration information to DHCP clients.
IPv6 Address range
(Start)
Enter the beginning of the range of IP addresses that this address object represents.
IPv6 Address range
(End)
Enter the end of the range of IP address that this address object represents.
