Configuring the Wireless Router

Network attacks that deny access to a network device are called 
Denial-of-Service (DoS) attacks. DoS attacks are aimed at devices and 
networks with a connection to the Internet. Their goal is not to steal 
information, but to disable a device or network so users no longer have 
access to network resources.
The Wireless Router firewall function protects against the following 
DoS attacks : IP Spoofing, Land Attack, Ping of Death, IP with zero 
length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, 
and TCP SYN flooding.
The firewall does not significantly affect system performance, so we 
advise leaving it enabled to protect your network. Select "Enable" and 
click the "SAVE SETTINGS" button to open the Firewall submenus.
4.8.1

not-permitted through the WAN interface. The default is to permit all 
outgoing traffic.

MAC Filter
The Wireless Router can also limit the network access based on the 
MAC address. The MAC Filtering Table allows the Wireless Router to 
enter up to 32 MAC addresses that are allowed to access to the WAN 
port.
1- Click "Yes" to enable, or "No" to disable this function
2- Enter the MAC address in the space provided and click "Save 
Settings" to confirm
4.8.3
URL blocking
The Wireless Router allows the user to block access to web sites by 
entering either a full URL address or just a keyword. This feature can be 
used to protect children from accessing violent or pornographic web 
sites.
4.8.4
Schedule rule
You may filter Internet access for local clients based on rules. Each 
access control rule may be activated at a scheduled time. Define the 
time schedule on this page, and apply the rule on the Access Control 
page.
4.8.5
Intrusion detection
Intrusion Detection Feature
Stateful Packet Inspection (SPI) and Anti-DoS firewall protection 
(Default : Enabled) - The Intrusion Detection Feature of the Wireless 
Router limits access for incoming traffic at the WAN port. When the 
SPI feature is turned on, all incoming packets will be blocked except for 
those types marked in the Stateful Packet Inspection section.
