Firewall
The 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.
It also 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.
NAT
Configures address mapping, virtual server and
special applications.
Wireless

for wireless communications.
