Activate the option, the Router can also work in Bridge mode.

¾

Connection:

For PPPoA/PPPoE connection, you can select

Always on

or

Connect

on-Demand

or

Connect Manually

. Connect on demand is dependent on the traffic. If there

is no traffic (or

Idle

) for a pre-specified period of time), the connection will tear down

automatically. And once there is traffic send or receive, the connection will be automatically

on.

¾

Static/Dynamic IP Address:

For PPPoA/PPPoE connection, you need to specify the public

IP address for this ADSL Router. The IP address can be either dynamically (via DHCP) or

given IP address provided by your ISP. For Static IP, you need to specify the IP address,

Subnet Mask and Gateway IP address.

Default Route:

You should select

Yes

to configure the PVC as the default gateway to

internet from this device.

¾

MAC Spoofing:

MAC Spoofing feature allows you to change the assigned MAC address of

the ADSL Router to a different one, which may allow the bypassing of access control lists on

servers either hiding a computer on a network or allowing it to impersonate another computer.

You can select

Enable

and specify a MAC Address for the Router here, or keep the default

setting as

Disable.

Bridge Mode

If you select this type of connection, the modem can be configured to act as a bridging device

between your LAN and your ISP. Bridges are devices that enable two or more networks to

communicate as if they are two segments of the same physical LAN.

Router Local IP:

These are the IP settings of the LAN interface for the device. These

settings may be referred to as Private settings. You may change the LAN IP address if

needed. The LAN IP address is private to your internal network and cannot be seen on the

Internet.

•

IP Address:

Enter the Router’s local IP Address, then you can access to the Web-based

Utility via the IP Address, the default value is 192.168.1.1.

•

IP Subnet Mask:

Enter the Router’s Subnet Mask, the default value is 255.255.255.0.

•

Dynamic Route:

Select this option to specify the RIP (Routing Information protocol)

version for LAN interface, including

RIP1

,

RIP2-B

and

RIP2-M

. RIP2-B and RIP2-M are

both sent in RIP2 format, the difference is that RIP2-M using Multicast, while RIP2-B

using Broadcast format.

•

Direction:

Select this option to specify the RIP direction.

None

is for disabling the RIP

function.

Both

means the ADSL Router will periodically send routing information and

accept routing information, and then incorporate them into routing table.

IN only

means

the ADSL router will only accept but will not send RIP packet.

OUT only

means the

ADSL router will only send but will not accept RIP packet.

•

Multicast:

Select IGMP version, or disable the function. IGMP (Internet Group Multicast

Protocol) is a session-layer protocol used to establish membership in a multicast group.

The ADSL ATU-R supports both IGMP version 1 (

IGMP v1

) and

IGMP v2

. Select

“Disabled” to disable it.

•

IGMP Snoop:

Enable the IGMP Snoop function if you need.

DHCP Server:

Select

Enabled

, then you will see the screen below (shown in Figure 4-12).

The Router will work as a DHCP Server, it becomes the default gateway for DHCP client

connected to it. DHCP stands for Dynamic Host Control Protocol. The DHCP Server gives

out IP addresses when a device is booting up and request an IP address to be logged on to

the network. That device must be set as a DHCP client to obtain the IP address automatically.

By default, the DHCP Server is enabled. The DHCP address pool contains the range of the

IP address that will automatically be assigned to the clients on the network.

•

Starting IP Address:

Enter the starting IP address for the DHCP server's IP assignment.

Because the default IP address for the Router is 192.168.1.1, the default Start IP

Address is

192.168.1.100

, and the Start IP Address must be 192.168.1.100 or greater,

but smaller than 192.168.1.254.

•

IP Pool Count:

The max user pool size.

•

Lease Time:

The length of time for the IP lease. After the dynamic IP address has

expired, the user will be automatically assigned a new dynamic IP address. The default

is

259200

seconds.

•

DNS Relay:

If you want to disable this feature, you just need to set both Primary and

secondary DNS IP to 0.0.0.0. If you want to use DNS relay, you can set up DNS server

IP to 192.168.1.1 on their Computer. If not, the device will perform as no DNS relay.

•

Primary DNS Server:

Type in your preferred DNS server.

•

Secondary DNS Server:

Type in your preferred DNS server.

•

Current Pool Summary:

Click the button, you can view the IP addresses that the DHCP

Server gives out.

Note:

If

Use Auto Discovered DNS Server Only

is selected in DNS Relay, this router will accept the

first received DNS assignment from one of the PPPoA, PPPoE or MER/DHCP enabled PVC(s)

during the connection establishment. If

Use User Discovered DNS Server Only

is selected in

DNS Relay, it is necessary for you to enter the primary and optional secondary DNS server IP

addresses. After type in the address, click SAVE button to save it and invoke it.

Router will work as a DHCP Relay. A DHCP relay is a computer that forwards DHCP data

between computers that request IP addresses and the DHCP server that assigns the

addresses. Each of the device's interfaces can be configured as a DHCP relay. If it is enabled,

the DHCP requests from local PCs will forward to the DHCP server runs on WAN side. To

have this function working properly, please run on router mode only, disable the DHCP server

on the LAN port, and make sure the routing table has the correct routing entry.
