SECURITY
Security
The first menu item in the Security section is Firewall. The Barricade
provides a stateful inspection firewall which is designed to protect against
Denial of Service (DoS) attacks when activated. Its purpose is to allow a
private local area network (LAN) to be securely connected to the Internet.
The second menu item is Wireless. This section allows you to configure
wireless security settings according to your environment and the privacy
level required.
To configure your firewall settings, click Firewall in the left-hand menu.
4-27
CONFIGURING THE BARRICADE
Firewall
The Barricade’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-ofService (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 Barricade 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
“Intrusion Detection” on page 4-35 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.

Intrusion Detection
The Barricade’s firewall inspects packets at the application layer, maintains
TCP and UDP session information including timeouts and number of
active sessions, and provides the ability to detect and prevent certain types
of network attacks such as Denial-of-Service (DoS) attacks.
4-35
CONFIGURING THE BARRICADE
Network attacks that deny access to a network device are called 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 Barricade protects against DoS attacks including: Ping of Death (Ping
flood) attack, SYN flood attack, IP fragment attack (Teardrop Attack),
Brute-force attack, Land Attack, IP Spoofing attack, IP with zero length,
TCP null scan (Port Scan Attack), UDP port loopback, Snork Attack.
Note: The firewall does not significantly affect system performance, so
we advise enabling the prevention features to protect your
network.

The Intrusion Detection feature of the Barricade
limits the access of incoming traffic at the WAN
port. When the Stateful Packet Inspection (SPI)
feature is turned on, all incoming packets are
blocked except those types marked with a check in
the SPI section at the top of the screen.
RIP Defect
Disabled If the router does not reply to an IPX RIP request
packet, it will stay in the input queue and not be
released. Accumulated packets could cause the
input queue to fill, causing severe problems for all
protocols. Enabling this feature prevents the
packets accumulating.
Discard Ping to
WAN
Don’t
discard
Prevents a ping on the router’s WAN port from
being routed to the network.
