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 ADSL Wireless Base Station 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. (See page 48-50 for details.)
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.
