3.2.2 General Setup
This page provides you the general settings for LAN. Click
LAN
to open the LAN settings
page and choose
General Setup
.
There are six subnets provided by the router which allow users to divide groups into different
subnets (LAN1 – LAN6). In addition, different subnets can link for each other by configuring
Inter-LAN Routing
. At present, LAN1 setting is fixed with NAT mode only. LAN2 – LAN6
can be operated under
NAT
or
Route
mode. IP Routed Subnet can be operated under Route
mode.
Available settings are explained as follows:
Item
Description
General Setup
Allow to configure settings for each subnet respectively.
Index -
Display all of the LAN items.
Status-
Basically, LAN1 status is enabled in default.
LAN2 –LAN6 and IP Routed Subnet can be observed by
checking the box of
Status
.
DHCP-
LAN1 is configured with DHCP in default. If
required, please check the DHCP box for each LAN.
IP Address -
Display the IP address for each LAN item.
Such information is set in default and you can not modify it.

LAN will have different LAN configuration page.
Each
LAN must be configured in different subnet.
IPv6 –
Click it to access into the settings page of IPv6.
Advanced
DHCP packets can be processed by adding option number
and data information when such function is enabled.
Enable/Disable
– Enable/Disable the function of DHCP
Option. Each DHCP option is composed by an option
number with data. For example,
Option number:100
Data: abcd
When such function is enabled, the specified values for
DHCP option will be seen in DHCP reply packets.
Interface
– Choose the interface for such option.
Option Number
– Type a number for such function.
DataType
– Choose the type (ASCII or Hex) for the data to
be stored.
Data
– Type the content of the data to be processed by the
function of DHCP option.
Force router to use DNS
server IP address …..
Force Vigor router to use DNS servers configured in
LAN1/LAN2/LAN3/LAN4/LAN5/LAN6 instead of DNS
servers given by the Internet Access server (PPPoE, PPTP,
L2TP or DHCP server).
Inter-LAN Routing
Check the box to link two or more different subnets (LAN
and LAN).
When you finish the configuration, please click
OK
to save and exit this page.

Details Page for LAN1 – Ethernet TCP/IP and DHCP Setup
There are two configuration pages for LAN1, Ethernet TCP/IP and DHCP Setup (based on
IPv4) and IPv6 Setup. Click the tab for each type and refer to the following explanations for
detailed information.
Available settings are explained as follows:
Item
Description
Network Configuration
For NAT Usage,
IP Address
- Type in private IP address for connecting to a
local private network (Default: 192.168.1.1).
Subnet Mask -
Type in an address code that determines the
size of the network. (Default: 255.255.255.0/ 24)
RIP Protocol Control,
Disable -
deactivate the RIP protocol. It will lead to a
stoppage of the exchange of routing information between
routers. (Default)
Enable –
activate the RIP protocol.
DHCP Server
Configuration
DHCP stands for Dynamic Host Configuration Protocol.
The router by factory default acts a DHCP server for your
network so it automatically dispatches related IP settings to
any local user configured as a DHCP client. It is highly
recommended that you leave the router enabled as a DHCP
server if you do not have a DHCP server for your network.
If you want to use another DHCP server in the network
other than the Vigor Router’s, you can let Relay Agent help
you to redirect the DHCP request to the specified location.
Enable Server -
Let the router assign IP address to every
host in the LAN.
Disable Server –
Let you manually assign IP address to
every host in the LAN.
Enable Relay Agent –
Specify which subnet that DHCP
server is located the relay agent should redirect the DHCP

request to.
DHCP Server IP Address –
It is available when
Enable Relay Agent
is checked.
Set the IP address of
the DHCP server you are going to use so the Relay
Agent can help to forward the DHCP request to the
DHCP server.
Start IP Address -
Enter a value of the IP address pool for
the DHCP server to start with when issuing IP addresses. If
the 1st IP address of your router is 192.168.1.1, the starting
IP address must be 192.168.1.2 or greater, but smaller than
192.168.1.254.
IP Pool Counts -
Enter the maximum number of PCs that
you want the DHCP server to assign IP addresses to. The
default is 50 and the maximum is 253.
Gateway IP Address -
Enter a value of the gateway IP
address for the DHCP server. The value is usually as same
as the 1st IP address of the router, which means the router is
the default gateway.
Lease Time
- Enter the time to determine how long the IP
address assigned by DHCP server can be used.
Clear DHCP lease for inactive clients periodically -
Whenever a DHCP client requests an IP address from the
LAN DHCP server, the server will give out an IP to this
client for a certain amount of time (e.g., 1 day). However,
even if this client only uses the IP for say 5 minutes, the
server still "reserves" 1 day for that client. Because a DHCP
server only has a limited number of IPs to lease to its
DHCP clients, soon enough all the IPs will be used out and
then no one will be able to get any IPs from this server
anymore. Therefore, this feature is used to get the IP back
from inactive clients (i.e. doesn't use the IP but the server
still reserves the IP for him).
DNS Server IP Address
DNS stands for Domain Name System. Every Internet host
must have a unique IP address, also they may have a
human-friendly, easy to remember name such as
www.yahoo.com. The DNS server converts the
user-friendly name into its equivalent IP address
.
Primary IP Address -
You must specify a DNS server IP
address here because your ISP should provide you with
usually more than one DNS Server. If your ISP does not
provide it, the router will automatically apply default DNS
Server IP address: 194.109.6.66 to this field.
Secondary IP Address -
You can specify secondary DNS
server IP address here because your ISP often provides you
more than one DNS Server. If your ISP does not provide it,
the router will automatically apply default secondary DNS
Server IP address: 194.98.0.1 to this field.
The default DNS Server IP address can be found via Online
Status:
Page 145 / 794
Vigor2860 Series User’s Guide
131
If both the Primary IP and Secondary IP Address fields are
left empty, the router will assign its own IP address to local
users as a DNS proxy server and maintain a DNS cache.
If the IP address of a domain name is already in the DNS
cache, the router will resolve the domain name immediately.
Otherwise, the router forwards the DNS query packet to the
external DNS server by establishing a WAN (e.g.
DSL/Cable) connection.
When you finish the configuration, please click
OK
to save and exit this page.
Details Page for LAN1 – IPv6 Setup
There are two configuration pages for LAN1, Ethernet TCP/IP and DHCP Setup (based on
IPv4) and IPv6 Setup. Click the tab for each type and refer to the following explanations for
detailed information. Below shows the settings page for IPv6.
It provides 2 daemons for LAN side IPv6 address configuration. One is
RADVD
(stateless)
and the other is
DHCPv6 Server
(Stateful).
Available settings are explained as follows:
