3.2 DHCP

Unless you already have a

DHCP

server on your internal network, choose

“Enable”

from the

DHCP.

A

DHCP

Server can automatically assign IP Address to each computer in your network.

It is highly recommended that you set your broadband router to act as a

DHCP

server. Be sure to set

your computers to be

DHCP

clients by setting their

TCP/IP

settings to

“Obtain an IP Address

Automatically.”

When you turn your computers on, they will automatically load the proper

TCP/IP

settings provided by the router. The

DHCP

Server will automatically allocate an

unused

IP address from the IP address

pool to the requesting computer. You must specify the

starting and ending address of the IP address pool.

•

DHCP Server:

Select

“Enable”

to use the

DHCP

server option of the broadband router.

If you already have a DHCP server in your network, set the router’s

DHCP

option to

“Disable”.

•

Start IP Address/ End IP Address:

Enter the starting/ Ending IP address for the DHCP server’s IP

assignment. Make sure the first three octets match the router’s IP address, i.e.,

192.168.1.xxx.

The value

must be located from

2 to 254.

•

Static DHCP:

If you need to specify your LAN clients to static IP addresses, you can enable this

function. And enter the LAN client’s IP address corresponding to its MAC address.

3.4 IP Access

This function allows network administrators to restrict up to five groups of specified network

users/computers from accessing the certain applications.

Before using this function, the network PCs that you want to control the access limitation

should be assigned one fixed IP Address individually.

•

LAN IP Range:

Enter the range of IP addresses which you want them to be a controlled group

to have the same access limitation.

•

Protocol:

Select the protocol type as

“TCP”

LAN IP Range

column and

1~999

in the Blocked Port column

and select the protocol type as

TCP,

then click

“Apply”

button. As the result, the user’s computers, which

have IP Address in the range of

192.168.1.3 to 192.168.1.7,

will not to be able to use the applications that

use port numbers from

1 to 999

and selected

TCP

protocol, such as web browsing.

Please check the 6

th

section to see more TCP/IP Port list for Internet Service.

3.5 Virtual Server

The router can be configured as a virtual server so that remote users accessing

Web or FTP

services via the public

IP address

can be automatically redirected to local servers in the

LAN.

The router firewall feature filters out unrecognized packets to protect your

LAN

network so all

networked computers connected to the router are invisible to the outside world. If you wish, you can

make some of the networked computers accessible from the Internet by enabling Virtual Server.

Depending on the requested service, the router will redirect the external service request to the

appropriate server within the

LAN

network.
