to connect with this device, it means the client can't access to the Internet either.

Choose "allow" or "deny" to allow or deny the clients, whose MAC addresses are

not in the "Control table" (please see below), to connect with this device.

3.

Association control:

Check "Association control" to enable the controlling of

which wireless client can associate to the wireless LAN. If a client is denied to

associate to the wireless LAN, it means the client can't send or receive any data

via this device. Choose "allow" or "deny" to allow or deny the clients, whose MAC

addresses are not in the "Control table", to associate to the wireless LAN.

MAC Address for Wake-on-LAN:

Input MAC address of host that you want

to use WOL.

2.

Discard PING from WAN side:

When this feature is enabled, any host on

the WAN cannot ping this product.

3.

DoS Attack Detection:

When this feature is enabled, the router will detect

and log the DoS attack coming from the Internet. Currently, the router can detect

the following DoS attack: SYN Attack, WinNuke, Port Scan, Ping of Death, Land

Attack etc.

4.

SPI mode:

You can enable this function and the router will check every

incoming packet to verify if this packet is valid or not, and drop those invalid

packets.

5.

Disable PPTP passthrough:

The PPTP passthrough is enabled by default.

You can disable here.

6.

Disable L2TP passthrough:

The L2TP passthrough is enabled by default.

You can disable here.

7.

Disable IPSec passthrough:

The IPSec passthrough is enabled by default.

8.

Stealth Mode:

If enable this option, router will become

“

if someone

uses port scan utility to scan available ports on this router.

4.2 QoS (Quality of Service)

Quality of Service (QoS) helps to prioritize data as it enters your router. By attaching

special identification marks or headers to incoming packets, QoS determines which

queue the packets enter, based on priority. This is useful when there are certain types of

data you want to give higher priority to, such as voice data packets given higher priority

than Web data packets.

This router provides two types of Cross-layer QoS (support throughout Application/

A-LINK WNAP4G

User Manual

Transport/ Data link/Network Layers in the network) tools. They are “Smart QoS” and

“User Defined Rule

-

based QoS” to help you easily configure the QoS that you need.

Please find more details in the later section.

The main goal of QoS is prioritizing incoming data, preventing data loss due to factors

such as jitter, delay and dropping. Another important aspect of QoS is ensuring that

prioritizing one data flow doesn’t interfere with other data flows.

QoS can be toggled

Activated and Deactivated. QoS must be activated before you can edit the following

options. When you are done making changes, click on

Save

to save your changes.

4.2.1 Smart QoS

1.

QoS :

you can select enable/disable the QoS control

2.

QoS Mode :

select “Smart

-

QoS” for your own Q

oS control

3.

Bandwidth of Upstream / Bandwidth of Downstream

: you can input the

value of maximize of upstream and downstream bandwidth from your ISP

4.

Flexible Bandwidth Management (FBM):

A.

When this management is enabled, system will share the bandwidth of those

selected applications to other applications if user do not run those selected

application, for example, If you select Game/ VoIP/ Video 3 applications for

higher priority in your system, then the system will automatically reserve 10% of

bandwidth to other application, and share the rest of bandwidth

(100-

10)/3=30% each to Game/VoIP/Video, so if user do not play a game, then the

system will flexible share the 30% of bandwidth to other application.

Example for Smart-QoS with FBM enable :

Mr. Wang selects Game/ VoIP/

Video 3 applications for higher priority in his system, the system will automatically

reserve 10% of minimum rate of bandwidth to other application, and share the

rest minimum rate of bandwidth

(100-10)/3=30% each to Game/VoIP/Video. If

M

r. Wang’s son plays on

-line game in the morning, the total bandwidth will all

reserve to his son. By the evening, when Mr. Wang back home and wants to

watch IPTV, then he will get the same priority with his son, and share the

bandwidth.

B.

When this management is disabled, system will allow you to input percentage

of bandwidth manually.
