3.1.5 WAN Budget
This function is used to determine the data
traffic volume
for each WAN interface respectively
to prevent from overcharges for data transmission by the ISP. Please note that the Quota Limit
and Billing cycle day of month settings will need to be configured correctly first in order for
some period calculations to be performed correctly.
General Setup
Click WAN1/WAN2/WAN3/WAN4 link to open the following web page.
Available settings are explained as follows:
Item
Description
Enable
Check the box to enable such function.
Quota Limit
Type the data traffic quota allowed for such WAN
interface. There are two unit (MB and GB) offered for you
to specify.
When quota exceeded
Check the box(es) as the condition(s) for the system to
perform when the traffic has exceeded the budget limit.
Shutdown WAN interface
– All the outgoing traffic
through such WAN interface will be terminated.
Send Mail Alert to Administrator
– The system will send
out a warning message to the administrator when the quota

is running out. However, the connection charges will be
calculated continuously.
Send SMS messages to Administrator
- The system will
send out SMS message to the administrator when the quota
is running out.
Monthly
Some ISP might apply for the network limitation based on
the traffic limit per month. This setting is to offer a
mechanism of resetting the traffic record every month.
Billing cycle starts from …
– The period of billing cycle is
about one month. You can determine the starting day of one
month as billing cycle.
User Defined
Some ISP might apply for the network limitation based on
the traffic limit per month. This setting allows the user to
define the billing cycle according to his request.
The WAN budget will be reset with an interval of billing
cycle.
User Defined
– Monthly is default setting. If long period or
a short period is required, use
User Defined
. The period of
billing cycle is between 1 day and 60 days. You can
determine the cycle duration by specifying the days and the
hours. In addition, you can specify which day of current day
in a cycle.
Billing cycle
: Specify the days to reset the traffic record.
For example, 7 means the whole cycle is 7 days; 20
means the whole cycle is 20 days. When the time is up,
the router will reset the traffic record automatically.
Current day in cycle
– Specify the day in the billing
cycle as the starting point which Vigor router will reset
the traffic record. For example, 3 means the third day of
the billing cycle.

The monitor page displays the status WAN budget, including the duration and the usage.
If the WAN budget is exhausted, a lock will be displayed on the page if

interface
is selected. Which means no data transmission will be carried out. Moreover, the
system will send out a warning message to the administrator if

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 8 virtual LANs. To manage the
communication between different groups, please set up rules in Virtual LAN (VLAN) function
and the rate of each.
