SECURITY4-27SecurityThe 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.
CONFIGURING THE BARRICADE4-28FirewallThe 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-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 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.

SECURITY4-35Intrusion DetectionThe 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.
CONFIGURING THE BARRICADE4-36Network 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.
SECURITY4-37The table below lists the Intrusion Detection parameters and their descriptions.Parameter Defaults DescriptionIntrusion Detection FeatureSPI and Anti-DoS firewall protection No 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.
