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 Access Control
Access Control allows users to define the outgoing traffic permitted or
not-permitted through the WAN interface. The default is to permit all
outgoing traffic.
To add the PC to the filtering table :
1- Click "Add PC" on the Access Control screen
2- Define the appropriate settings for client PC services
3- Click "OK" and then click "SAVE SETTINGS" to save your settings
4.8.2 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.
