WDS
The Wireless Distribution System (WDS) provides a means to extend the 
range of a Wireless Local Area Network (WLAN). WDS allows the 
Barricade to establish a direct link to other wireless base stations and 
allows clients to roam freely within the area covered by the WDS. To carry 
out a site survey of available wireless base stations, click Scan.
Parameter Description

wireless network. The SSID must be the same on 
the Barricade and all of its wireless clients.

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.

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-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.
