interface
Choose the WAN interface (WAN1 or WAN2) for binding.
Src IP Start
Type the source IP start for the specified WAN interface.
Src IP End

field is blank, it means that all the source IPs inside the LAN will
be passed through the WAN interface.

field is blank, it means that all the destination IPs will be passed
through the WAN interface.
Dest Port Start
Type the destination port start for the destination IP.

3.2 LAN
Local Area Network (LAN) is a group of subnets regulated and ruled by router. The design
of network structure is related to what type of public IP addresses coming from your ISP.
3.2.1 Basics of LAN
The most generic function of Vigor router is NAT. It creates a private subnet of your own. As
mentioned previously, the router will talk to other public hosts on the Internet by using
public IP address and talking to local hosts by using its private IP address. What NAT does is
to translate the packets from public IP address to private IP address to forward the right
packets to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that
assigns private IP address to each local host. See the following diagram for a briefly
understanding.
In some special case, you may have a public IP subnet from your ISP such as
220.135.240.0/24. This means that you can set up a public subnet or call second subnet that
each host is equipped with a public IP address. As a part of the public subnet, the Vigor
router will serve for IP routing to help hosts in the public subnet to communicate with other
public hosts or servers outside. Therefore, the router should be set as the gateway for public
hosts.

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.
(Default: 255.255.255.0/ 24)

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
of the router, which means the router is the default gateway.
