ONFIGURING THE
LNWR100T
Firewall
The LNWR100T’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 LNWR100T 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 4-46 for details.)
The firewall does not significantly affect system performance, so
we advise leaving it enabled to protect your network.
Enable
the firewall feature, and click
Save Settings
to proceed.
