P

rotocol is a VPN protocol that will ensure a direct connection to the server

using an authentication process that guarantees the data originated from the claimed sender and was not

damaged or altered in transit. Once connected to the VPN tunnel, it seems to the user that the client computer

is directly connected to the internal network. To set up your L2PT connection, enter the following data that

was provided to you by your ISP.

L2TP connection setup menu

There are two ways to enable the router to become a L2TP client, one is through assigning the router an IP

address dynamically, which means that the DHCP protocol will be implemented by the Router to

automatically configure the IP settings. The user may input the IP settings manually by choosing the Static

IP option above the configuring area. To configure the router to be a L2TP client, complete the following

fields and click the

Save Settings

button.

Settings for L2TP conntections:

IP Address

Enter the IP address of the router into this field. This address must be

supplied to you by your ISP. This field will not be necessary to

configure if the Dynamic IP option is chosen above the configuring

field.

Subnet Mask

Enter the IP address of the Subnet Mask into this field. This address

must be supplied to you by your ISP. This field will not be necessary to

configure if the Dynamic IP option is chosen above the configuring

field.

Gateway

Enter the IP address of the gateway into this field. This address must

be supplied to you by your ISP. This field will not be necessary to

configure if the Dynamic IP option is chosen above the configuring

field.

DNS

Enter the IP address of the DNS. This field will not be necessary to

configure if the Dynamic IP option is chosen above the configuring

field.

Server IP/Name

Enter the Server IP address for this protocol into this field. This is the

IP address of the server computer that will be used, along with your

computer, to create the Virtual Private Network. This field must be

completed for both the Dynamic IP and Static IP options

L2TP Account

Enter the L2TP account name, provided to you by your ISP, here.

L2TP Password

Enter your password for this L2TP account here, as stated to you by

your ISP.

L2TP Retype

Password

Retype the password entered in the

L2TP Password

field.

Maximum Idle

Time

A value of 0 in this field means that the L2TP connection will remain

connected. If your network account is billed according to the amount of

time the Router is actually connected to the Internet, enter an

appropriate Idle Time value (in seconds). This will disconnect the

Router after the WAN connection has been idle for the amount of time

specified. The default value = 5.

MTU

This field refers to the Maximum Transfer Unit, which is the maximum

size of a packet, in bytes, that will be accepted by the router. The

default setting is 1460 bytes. This field should not be altered unless

instructed by your ISP.

Connect Mode

Select

This function, with

Connect-on-demand

selected, will allow the router

to connect any workstation on your LAN to the Internet upon request.

If this function is set at

Always-on

, no request from the workstation

will be needed to connect to the Internet. If

Manual

is selected, it will

be necessary for the workstation on the LAN to manually connect to the

Internet through this router.

BigPond (Australia)

This selection is for users having BigPond Cable as their ISP. Enter the following information, as provided to

you by your ISP.

User Name

The user name supplied to you by your ISP.

Password

The password supplied to you by your ISP.

feld.

Auth Server

Toggle the Authentication Server between

sm-server

and

dce-server

.

Login Server

IP/Name

Enter the IP address given to you by your ISP. This field is optional.

MAC Address

This field requires the user to enter the Media Access Control (MAC)

address of the Ethernet Card of your computer, if instructed to do so by

your ISP. To quickly accomplish this, click the

Duplicate MAC address

from the customer end

button, which will automatically copy the MAC

address of your Ethernet card and enter it into the space provided, which

will replace the MAC address of the router.

LAN Setup

Use this window to configure Router LAN IP Settings and DHCP Server Settings. When you are finished,

click the

Save Settings

button at the top of the window.

Network IP Settings menu

Router Settings

This section is used to configure the internal network settings of the Router. This IP address is private to

your internal network and cannot be seen on the Internet. The default

Router IP Address

is 192.168.0.1 and

the

Default Subnet Mask

is 255.255.255.0. The

Local Domain Name

is for the local Domain set on your

network, if you have given it a name previously. This field is for your personal use and unnecessary for

proper configuration of this window.

In addition, the Router can be configured to relay DNS from your ISP or another available service to

workstations on your LAN. When

Enable DNS Relay

is checked, the Router will accept DNS requests from

hosts on the LAN and forward them to the ISP (or alternative) DNS servers. Alternatively, you may also

disable the DNS relay and configure hosts on your LAN to use DNS servers directly. Most users who are

using the Router for DHCP service on the LAN and are using DNS servers on the ISP’s network, will leave

DNS relay enabled.

DHCP Server Settings

Dynamic Host Configuration Protocol (DHCP) allows the gateway to automatically obtain the IP address

from a DHCP server on the service provider’s network. The service provider assigns a global IP address

from a pool of addresses available to the service provider. Typically the IP address assigned has a long lease

time, so it will likely be the same address each time the Router requests an IP address. If DHCP is not

enabled on the Router, it is necessary for the user to assign a static IP address to each computer on your

LAN.

To set up DHCP for your LAN, first enable the Router as a DHCP server by clicking the

Enable DHCP

Server

radio button in the window above. The next step is to set a range of IP addresses that you wish to

allot to the devices on your LAN by entering a starting and ending number of addresses within the LAN

subnet in the

DHCP IP Address Range

. This may be in a range from 2 to 254 (192.168.0.2 –

192.168.0.254). Computers on your LAN will have an IP address within this range then automatically

assigned to them. Finally, choose the

DHCP

Lease Time

, which is the time the Server will set for devices

using DHCP to re-request an IP Address. Clients authorized for DHCP will be listed in the Dynamic DHCP

Client List near the bottom of the window. Click

Save Settings

to implement information set in this table.

The DHCP Server is enabled by default.

DHCP may also be statically configured as well. This method allows the router to assign the same IP address

information to a specific computer on the network, defined by its MAC address. This computer will get the

same DHCP implemented IP address information every time the computer is turned on and this IP address

will be specific to that computer’s IP address on the local network. No other computer can be assigned this

address. This is useful for computers on the LAN that are hosting applications such as HTTP or FTP. First,

the user must enter the

Host Name

and the

IP Address

for that computer in the spaces provided. Next, the

user must enter the

MAC Address

of the computer in the space provided. Click

Save Settings

to implement

these static settings.
