5.2.5 DNS Relay

The DNS Configuration allows the user to set the configuration of DNS.

DNS Relay Selection:

If user wants to disable this feature, he just needs to set both Primary &

Secondary DNS to 0.0.0.0. Using DNS relay, users can setup DNS server IP to 192.168.1.1 on

their computer. If not, device will perform with NO DNS relay feature.

If you don’t want to use the DNS Relay option, set the DNS relay to “

Use User

Discovered

DNS Server Only

” and set both Primary and Secondary DNS Servers to

“

0.0.0.0

”.

5.3.1 Access Point Settings

Access Point:

Select this section for Activated or Deactivated AP function.

Channel:

Select the local channel from the drop down list.

Beacon Interval:

The Beacon Interval value indicates the frequency interval of the beacon. Enter a

value between 20 and 1000. A beacon is a packet broadcast by the Router to synchronize the wireless

network.

RTS/CTS Threshold:

The RTS (Request To Send) threshold (number of bytes) for enabling RTS/CTS

handshake. Data with its frame size larger than this value will perform the RTS/CTS handshake. Set

this attribute to be larger than the maximum MSDU (MAC Service Data Unit) size TURNS OFF the

RTS/CTS handshake. Set this attribute to ZERO TURNS ON the RTS/CTS handshake. Enter a value

between 0 and 2432.

Fragment Threshold:

The threshold (number of bytes) for the fragmentation boundary for directed

messages. It is the maximum data fragment size that can be sent. Enter a value between 256 and 2432.

DTIM: This value is between 1 and 255, indicates the interval of the Delivery Traffic Indication

Message (DTIM).

802.11 b/g: Select the wireless mode in the sectio

n.

5.3.2 Multiple SSIDs Settings

SSID:

The SSID is a unique name to identify the ADSL Router in the Wireless LAN. Wireless Clients

associating to the ADSL Router must have the same SSID. The default SSID name is

WF200.

.

Broadcast SSID

: Select

No

to hide the SSID such that a station (PC, laptop, PDA etc) can not obtain

the SSID through passive scanning. Select

Yes

to make the SSID visible so a station can obtain in the

SSID through Passive scanning.

Authentication Type:

Select wireless authentication type to configure wireless AP. There are 4

available types – WEP-64Bits, WEP-128Bits, WPA-PSK, WPA2-PSK.

[Authentication Type]

WEP

(Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network.

Select

Disable

to allow all wireless computers to communicate with the access points without any data

encryption. Select

64-bit WEP

or

128-bit WEP

to use data encryption.

Key#1~Key#4

The WEP keys are used to encrypt data. Both the ADSL Router and the wireless clients

must use the same WEP key for data transmission. If you chose

64-bit WEP

, then enter any

10

hexadecimal digits (“0-9”, “A-F”) preceded by 0x for each key (1-4). If you choose

128bit WEP

, then

enter

26

hexadecimal digits (“0-9”, “A-F”) preceded by 0x for each key (1-4). The values must be set

up exactly the same on the Access Points as they are on the wireless client stations. The same value

must be assigned to Key 1 on both access point (your ADSL Router) and the client adapters, the same

value must be assigned to Key 2 on both access point and the client stations and so on, for all four WEP

keys.

WPA-PSK

Wi-Fi Protected Access, pre-shared key. Encrypts data frames before transmitting over the

wireless network.

Pre-shared Key

is used to encrypt data. Both the ADSL Router and the wireless clients must use the

same WPA-PSK Key for data transmission.

5.3.3 WDS Settings

A WDS (Wireless Distribution System) is a system that enables the interconnection of access points

wirelessly. It allows a wireless network to be expanded using multiple access points without the need

for a wired backbone to link them.

WDS is another way for AP router to join an existing Wi-Fi network. The WDS feature is normally

used in large, open areas where pulling a wire is restricted or not cost effective in residential

installations. User can use this feature to build up a large wireless network in a large space like airports,

hotels and schools…etc. This feature is also useful when users want to bridge networks between

buildings where it is impossible to deploy network cable connections between these buildings.

WDS Mode: (1) Restricted – WDS peers must be registered with AP router (by MAC

addresses). (2) Bridge – AP router will function as a wireless bridge, forwarding traffic between access

points, and will not respond to wireless requests. The WDS peers must be manually stated and wireless

stations will not be able to connect to AP router. (3) Repeater – AP router will act as a repeater,

interconnecting between access points. WDS peers can be determined by the user (“Restricted” mode)

or auto-detected (“Lazy” mode) (4) Lazy– Automatic detection of WDS peers: when a LAN user

searches for a network, AP router will attempt to connect to WDS devices in its vicinity.

MAC address #1~#4: Specify the destination MAC address device. The MAC addresses filter

tunnelling lets you select exactly which stations should have access to your network.

5.3.4 Wireless MAC Address Filter

You can allow or deny a list of MAC addresses associated with the wireless stations access to the

ADSL Router.

Active:

Select this section to activate or deactivate Wireless MAC address filter.

Action:

Select

Deny Association

to block access to the router, MAC addresses not listed will be

allowed to access the router. Select

Allow Association

to permit access to the router, MAC addresses

not listed will be denied access to the router.

6 Advanced Setup

6.1 Firewall

User can enable or disable firewall feature of the ADSL router in the following page.

Firewall:

Select this option can automatically detect and block Denial of Service (DoS) attacks, such

as Ping of Death, SYN Flood, Port Scan and Land Attack.

SPI:

Select this option to Enabled or Disabled the SPI feature.

(

NOTE:

If you enable SPI, all traffics

initiate from WAN would be blocked, including DMZ, Virtual Server, and ACL WAN side)

6.2 Routing

This table lists IP address of Internet destinations commonly accessed by your network. When a

computer requests to send data to a listed destination, the device uses the Gateway IP to identify the

first Internet router it should contact to route the data most efficiently. Select this option will list the

routing table information. You can press

ADD ROUTE

to edit the static route. (As below screen)

[Static Route]

Select this option to set Static Routing information.

Destination IP Address:

This parameter specifies the IP network address of the final destination of

packets routed by this rule.

IP Subnet Mask:

Enter the subnet mask for this destination.

Gateway IP Address:

Enter the IP address of the gateway. A

gateway

does the actual forwarding of

the packets. Enter the gateway’s IP address in the field or select which PVC you wish to act as a

gateway.

The gateway is an immediate neighbor of your ADSL Router that will forward the packet to the

destination. On the LAN, the gateway must be a router on the same segment as your Router; over

Internet (WAN), the gateway must be the IP address of one of the remote nodes.

Metric:

Metric represents the “cost” of transmission for routing purposes. IP Routing uses hop count as

the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that

approximates the cost for this link. The number need not to be precise, but it must between 1 and 15. In

practice, 2 or 3 is usually a good number.

Announced in RIP:

This parameter determines if the ADSL router includes the router to this remote

node in its RIP broadcasts. If you choose

Yes

, the router in this remote node will be propagated to other

hosts through RIP broadcasts. If you choose

No

, this route is kept private and is not included in the RIP

broadcasts.

When you have finished making changes, click on

SAVE

to save your changes,

DELETE

to delete the

rule with the parameters you set,

BACK

to return to the previous screen or

CANCEL

to exit without

saving.

6.3 NAT

Network Address Translation (NAT)

is a method for disguising the private IP addresses you use on

your LAN as the public IP address you use on the Internet. You define NAT rules that specify exactly

how and when to translate between public and private IP addresses. Simply select this option to setup

the NAT function for your ADSL router.
