5.5.1 Block WAN Ping

Check the “Discard PING from WAN side” to enable blocking WAN ping. When you “Block

WAN Ping”, you are causing the public WAN IP address on the device to not respond to ping

commands. Pinging public WAN IP address is a common method used by hackers to test whether

you WAN IP address is valid and supports a network. Click APPLY to complete your change.

5.5.2 MAC Control

You can block certain clients PCs accessing the internet based on MAC address.

When you enable “MAC Address Control” without allowing unspecified MAC address

connect to internet, you will block all client PCs accessing the internet. The clients whose MAC

addresses listed in the “MAC Address Control List” can access the internet only if the “Allow

Connect to Internet is checked.

5.5.3 Client Filtering

You can block certain client PCs accessing the internet based on time. IP Filtering can filter the

packets sent from clients. For example, you can ban WEB browsing by setting the port to “80”.

Remember to select the Check box in the “Enable”. Click

Wireless Setting

5.6.1 General

the Radio channel and SSID. If you don’t want to utilize WEP Encryption, select “Disable” to

disable this function.

General:

1.

SSID

: The SSID is a unique name shared among all points in your wireless network. The

SSID must be identical for all points in the network. It is case sensitive and must not exceed

32 characters.

2.

Channel

: The channel shared by all wireless devices. The range of channel is 1~14.

WEP

:

Short for Wired Equivalent Privacy, a security protocol for wireless local area networks

(WLANs) defined in the 802.11b standard. WEP is designed to provide the same level of security as

that of a wired LAN. Select

Open System -

An open system allows any client to authenticate as long as it conforms to any MAC address filter

policies that may have been set. All authentication packets are transmitted without encryption.

2

Shared Key -

when both the sender and the receiver share a secret key. When "Shared Key" is checked, the AP sends

an unencrypted challenge text string to any device attempting to communicate with the AP. The device requesting

authentication encrypts the challenge text and sends it back to the access point. If the challenge text is encrypted

correctly, the access point allows the requesting device to authenticate.

3

Auto

– No matter the authentication packets with encryption or not, the access point allows the requesting device to

authenticate.
