DHCP Server IP Address for Relay Agent -

Set the IP address of

the DHCP server you are going to use so the Relay Agent can help

to forward the DHCP request to the DHCP server.

DNS Server

Configuration

DNS stands for Domain Name System. Every Internet host must

have a unique IP address, also they may have a human-friendly,

easy to remember name such as www.yahoo.com. The DNS server

converts the user-friendly name into its equivalent IP address

.

Force DNS manual setting -

Force router to use DNS servers in

this page instead of DNS servers given by the Internet Access

server (PPPoE, PPTP, L2TP or DHCP server).

Primary IP Address -

You must specify a DNS server IP address

here because your ISP should provide you with usually more than

one DNS Server. If your ISP does not provide it, the router will

automatically apply default DNS Server IP address: 194.109.6.66

to this field.

Secondary IP Address -

You can specify secondary DNS server IP

address here because your ISP often provides you more than one

DNS Server. If your ISP does not provide it, the router will

automatically apply default secondary DNS Server IP address:

194.98.0.1 to this field.

The default DNS Server IP address can be found via Online Status:

If both the Primary IP and Secondary IP Address fields are left

empty, the router will assign its own IP address to local users as a

DNS proxy server and maintain a DNS cache.

If the IP address of a domain name is already in the DNS cache, the

router will resolve the domain name immediately. Otherwise, the

router forwards the DNS query packet to the external DNS server

by establishing a WAN (e.g. DSL/Cable) connection.

There are two common scenarios of LAN settings that stated in Chapter 4. For the

configuration examples, please refer to that chapter to get more information for your

necessity.

3.2.3 Static Route

Go to

LAN

to open setting page and choose

Static Route

.

Index

The number (1 to 10) under Index allows you to open next page to

set up static route.

Destination Address

Displays the destination address of the static route.

Status

Displays the status of the static route.

Viewing Routing Table

Displays the routing table for your reference.

Add Static Routes to Private and Public Networks

Here is an example of setting Static Route in Main Router so that user A and B locating in

different subnet can talk to each other via the router. Assuming the Internet access has been

configured and the router works properly:

z

use the Main Router to surf the Internet.

z

create a private subnet 192.168.10.0 using an internal Router A (192.168.1.2)

z

create a public subnet 211.100.88.0 via an internal Router B (192.168.1.3).

z

have set Main Router 192.168.1.1 as the default gateway for the Router A 192.168.1.2.

Before setting Static Route, user A cannot talk to user B for Router A can only forward

recognized packets to its default gateway Main Router.

Go to

LAN

page and click

General Setup

, select 1st Subnet as the

RIP Protocol Control.

Then click the

OK

button.

Note:

There are two reasons that we have to apply RIP Protocol Control on 1st

Subnet. The first is that the LAN interface can exchange RIP packets with the

neighboring routers via the 1st subnet (192.168.1.0/24). The second is that those hosts

on the internal private subnets (ex. 192.168.10.0/24) can access the Internet via the

router, and continuously exchange of IP routing information with different subnets.

1.

Click the

LAN - Static Route

and click on the

Index Number 1.

Check the

Enable

box. Please add a static route as shown below, which regulates all packets destined to

192.168.10.0 will be forwarded to 192.168.1.2. Click

OK

.

2.

Return to

Static Route

Setup

page. Click on another

Index Number

to add another

static route as show below, which regulates all packets destined to 211.100.88.0 will be

forwarded to 192.168.1.3.

3.

Go to

Diagnostics

and choose

3.2.4 VLAN

Virtual LAN function provides you a very convenient way to manage hosts by grouping

them based on the physical port. You can also manage the in/out rate of each port. Go to

LAN

page and select

VLAN

. The following page will appear. Click

Enable

to invoke

VLAN function.

To add or remove a VLAN, please refer to the following example.

1.

If, VLAN 0 is consisted of hosts linked to P1 and P2 and VLAN 1 is consisted of hosts

linked to P3 and P4.

2.

After checking the box to enable VLAN function, you will check the table according to

the needs as shown below.

To remove VLAN, uncheck the needed box and click

OK

to save the results.

3.2.5 Bind IP to MAC

This function is used to bind the IP and MAC address in LAN to have a strengthen control in

network. When this function is enabled, all the assigned IP and MAC address binding

together cannot be changed. If you modified the binding IP or MAC address, it might cause

you not access into the Internet.

Click

LAN

and click

Bind IP to MAC

to open the setup page.

Enable

Click this radio button to invoke this function.

However, IP/MAC

which is not listed in IP Bind List also can connect to Internet.

Disable

Click this radio button to disable this function. All the settings on

this page will be invalid.

Strict Bind

Click this radio button to block the connection of the IP/MAC

which is not listed in IP Bind List.

ARP Table

This table is the LAN ARP table of this router. The information

for IP and MAC will be displayed in this field. Each pair of IP
