DNS

You can assign DNS server(s) to the DHCP clients so the Router will use the DNS server(s) for faster access to

functioning DNS server(s). You do not need to complete either of these

DNS Server

fields; it is an optional feature.

WINS

Windows Internet Naming Service (WINS) is a service that resolves NetBIOS names to IP addresses. WINS is

assigned if the computer (DHCP client) requests one. If you do not know the IP address of the WINS server, keep

the default,

0.0.0.0

.

DHCP Tab - Status

A Status page is available so you can view the status information for the DHCP server and its clients.

Status

For the DHCP server, the following information is shown:

•

DHCP Server. This is the IP address of the DHCP server.

•

Dynamic IP Used. It shows the number of dynamic IP addresses used.

•

Static IP Used. It shows the number of static IP addresses used.

•

DHCP Available. This indicates the number of dynamic IP addresses available.

•

Total. It shows the total number of dynamic IP addresses that can be assigned by the DHCP server.

Client Table

For all network clients using the DHCP server, the Client Table shows the current DHCP Client information:

•

Client Host Name. This is the name assigned to a client host.

•

IP Address. It is the dynamic IP address assigned to a client.

•

MAC Address. This indicates the MAC address of a client.

•

Leased Time. It displays the amount of time a network user will be allowed connection to the Router with their

current dynamic IP address.

Click the

Trash Can

icon to delete a DHCP client, and the client host’s IP address will be released. Click the

Refresh

button to refresh the on-screen information.

Load Balance

For the Load Balance feature, you have a choice of Intelligent Balancer (Auto Mode) and IP Group (By Users),

except for WAN1. The Router reserves at least one WAN port for non-IP Group users, so WAN1 will always be set

to Intelligent Balancer (Auto Mode).

If you change the Router’s Load Balance Mode, a confirmation message will appear. You have to save this change

before you can change the settings of any WAN ports.

Intelligent Balancer (Auto Mode)

Select the

Intelligent Balancer (Auto Mode)

setting if you want all WAN ports to be in Auto Mode. The Router

will automatically compute the maximum bandwidth of all WAN ports by using Weighted Round Robin to balance

the loading.

In the Interface Setting table, the number of each WAN port is shown in the Interface column. Its Load Balance

Mode is displayed in the Mode column. Click the

Edit

in the Config. column to edit the Load Balance setting of the

selected WAN port. The

Edit Load Balance

screen will appear.

In the

Interface

field, the WAN port number is displayed. For the Max. Bandwidth provided by ISP setting, select

You can enable the Router to check the network service layer using DNS lookup. This tool can detect the network

connection status of the ISP if you have set up the DNS server in the Network section of the Setup page. If you did

not set up the DNS server, the checkbox will be grayed out, and then you cannot use the DNS lookup tool. The

default is unchecked. To use this tool, enter the host name and select the appropriate option from the

When Fail

drop-down menu. Using DNS lookup, the Router will check the network service layer every 15 minutes to see if

the network connection to your ISP is active.

The

When Fail

drop-down menu offers two options. If the connection is not active, the Router will generate a

system log or suspend this WAN interface. For the

Generate System Log

setting, the Router will generate a

system log when DNS lookup fails to inform you that the ISP connection may be disconnected. For the

Suspend

this WAN Interface

setting, the Router will suspend this WAN interface when the network connection to your ISP

is not active. The traffic on this WAN will be dispatched to the other WAN ports in Auto Mode. When the ISP

connection is re-established, traffic will return to this WAN interface.

IP Group (By Users)

IP Group (By Users) mode enables you to group traffic by different priority levels or classes of service (CoS). It can

ensure bandwidth and higher priority for the specific IP addresses of important users, and the IP Group users

don’t need to share bandwidth with lower classification users who use Intelligent Balancer mode.

In the Interface Setting table, the number of each WAN port is shown in the Interface column. If you have set the

IP Group for a selected WAN port, it will show the message, “Dispatched by user” in the Mode column. If you did

not set the IP Group for a selected WAN port, it will show the message, “Dispatched by system” in the Mode

column.

After you have selected IP Group (By Users), then click the

Edit

in the Config. column to edit the Mode setting of

the selected WAN port. The
