4.3.4 DNS

Domain Name Servers (DNS) are used to map a domain name (e.g.,
www.philips.com) with the IP address (e.g., 64.147.25.20). The DNS
address is usually configured automatically. If this is not the case, one or
more DNS address will be provided to you by your ISP.

4.4.1 Firewall

The ADSL Wireless Base Station's firewall inspects packets at the
application layer, maintains TCP and UDP session information including
time-outs and the number of active sessions, and provides the ability to
detect and prevent certain types of network attacks.
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.
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.
