What is Routing Information Protocol (RIP)
Vigor router will exchange routing information with neighboring routers using the RIP to
accomplish IP routing. This allows users to change the information of the router such as IP
address and the routers will automatically inform for each other.
What is Static Route
When you have several subnets in your LAN, sometimes a more effective and quicker way
for connection
is the
Static routes
function rather than other method. You may simply set
rules to forward data from one specified subnet to another specified subnet without the
presence of RIP.
What are Virtual LANs and Rate Control
You can group local hosts by physical ports and create up to 4 virtual LANs. To manage the
communication between different groups, please set up rules in Virtual LAN (VLAN)
function and the rate of each.

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
.
1st IP Address
Type in private IP address for connecting to a local private network
(Default: 192.168.1.1).
1st Subnet Mask
Type in an address code that determines the size of the network.
(Default: 255.255.255.0/ 24)
For IP Routing Usage
Click
Enable
to invoke this function. The default setting is
Disable
.
2
nd
IP Address
Type in secondary IP address for connecting to a subnet.
(Default: 192.168.2.1/ 24)
2
nd
Subnet Mask
An address code that determines the size of the network.

DHCP Server
You can configure the router to serve as a DHCP server for the 2nd
subnet.

Start IP Address:
Enter a value of the IP address pool for the
DHCP server to start with when issuing IP addresses. If the 2nd IP
address of your router is 220.135.240.1, the starting IP address
must be 220.135.240.2 or greater, but smaller than
220.135.240.254.
IP Pool Counts:
Enter the number of IP addresses in the pool. The
maximum is 10. For example, if you type 3 and the 2nd IP address
of your router is 220.135.240.1, the range of IP address by the
DHCP server will be from 220.135.240.2 to 220.135.240.11.
MAC Address:
Enter the MAC Address of the host one by one
and click
Add
to create a list of hosts to be assigned, deleted or
edited IP address from above pool. Set a list of MAC Address for
2
nd
DHCP server will help router to assign the correct IP address of
the correct subnet to the correct host. So those hosts in 2
nd
subnet
won’t get an IP address belonging to 1
st
subnet.
RIP Protocol Control
Disable
deactivates the RIP protocol. It will lead to a stoppage of
the exchange of routing information between routers. (Default)
1st Subnet -
Select the router to change the RIP information of the
1st subnet with neighboring routers.
2nd Subnet -
Select the router to change the RIP information of
the 2nd subnet with neighboring routers.
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 dispatch 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.
Relay Agent – (1
st
subnet/2
nd
subnet)
Specify which subnet that
DHCP server is located the relay agent should redirect the DHCP
request to.
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
Page 54 / 298

46
of the router, which means the router is the default gateway.
DHCP Server IP Address for Relay Agent -
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.
DNS Server
Configuration
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
.
Force DNS manual setting -
Force Vigor router to use DNS
servers in this page instead of DNS servers given by the Internet
Access server (PPPoE, PPTP, L2TP or DHCP server).
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:
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.
There are two common scenarios of LAN settings that stated in Chapter 4. For the
configuration examples, please refer to that chapter to get more information for your
necessity.
3.2.3 Static Route
Go to
LAN
to open setting page and choose
Static Route

Index
The number (1 to 10) under Index allows you to open next page to
set up static route.
Destination Address
Displays the destination address of the static route.
Status
Displays the status of the static route.
Viewing Routing Table
Displays the routing table for your reference.
Add Static Routes to Private and Public Networks
Here is an example of setting Static Route in Main Router so that user A and B locating in
different subnet can talk to each other via the router. Assuming the Internet access has been
configured and the router works properly:
z
use the Main Router to surf the Internet.
z
create a private subnet 192.168.10.0 using an internal Router A (192.168.1.2)
z
create a public subnet 211.100.88.0 via an internal Router B (192.168.1.3).
z
have set Main Router 192.168.1.1 as the default gateway for the Router A 192.168.1.2.
Before setting Static Route, user A cannot talk to user B for Router A can only forward
recognized packets to its default gateway Main Router.
