•Virtual Server
If you have a fixed IP address, you can set up the Wireless Barricade
Plus to act as a virtual host using network address translation (NAT).
Remote users access various services at your site using a constant
IP address. Then, depending on the requested service (or port
number), the Wireless Barricade Plus can route the request to the
appropriate server (at another internal IP address). This secures
your network from direct attack by hackers, and provides more
flexible management by allowing you to change internal IP
addresses without affecting outside access to your network.
• DMZ Host Support
Allows a networked computer to be fully exposed to the
Internet.
• Security
The Wireless Barricade Plus supports security features that can deny
Internet access to specified users, or filter all requests for specific
services the administrator does not want to serve. The Wireless
Barricade Plus’ firewall can also block common hacker attacks,
including 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.
• Stateful Packet Inspection (SPI)
Stateful Packet Inspection is one of the firewall features provided
by the Wireless Barricade Plus. The SPI ensures that the data coming
into your network was requested by an end node computer on your
network. The Wireless Barricade Plus examines the incoming data and
compares it to a database of trusted information. As traffic leaves
the network, it is defined by certain characteristics. Incoming
information is then compared to these sets of characteristics. If
the incoming data matches the predefined set of characteristics,
