THE

BARRICADE

4-52

The use of IEEE 802.1X offers an effective framework for authenticating

and controlling user traffic to a protected network, as well as dynamically

varying encryption keys. 802.1X ties EAP (Extensible Authentication

Protocol) to both the wired and wireless LAN media and supports

multiple authentication methods, such as token cards, Kerberos, one-time

passwords, certificates, and public key authentication.

Note:

Changing some of the device settings in the Advanced Settings

mode may cause the BARRICADE to become unresponsive.

The BARRICADE’s advanced management interface contains 6 main

menu items as described in the following table.

Menu

Description

NAT

Shares a single ISP account with multiple users, sets up virtual

servers.

Maintenance Allows you to backup, restore, reset, and upgrade the

BARRICADE’s firmware.

System

Sets the local time zone, the password for administrator access, the

IP address of a PC that will be allowed to manage the BARRICADE

remotely, and the IP address of a Syslog Server.

UPnP

Universal Plug and Play (UPnP) allows for simple and robust

connectivity between external devices and your PC.

DNS

Sets the IP address of a Domain Name Server.

DDNS

Dynamic DNS provides users on the Internet with a method to tie

their domain name to a computer or server.

Routing

Sets routing parameters and displays the current routing table.

NAT

The first menu item in the Advanced Settings section is Network Address

Translation (NAT). This process allows all of the computers on your home

network to use one IP address. Using the NAT capability of the

BARRICADE, you can access the Internet from any computer on your

home network without having to purchase more IP addresses from your

ISP.

To use the NAT feature, check the

Enable

radio button and click

Address Mapping

Network Address Translation (NAT) allows IP addresses used in a private

local network to be mapped to one or more addresses used in the public,

global Internet. This feature limits the number of public IP addresses

required from the ISP and also maintains the privacy and security of the

local network. We allow one public IP address to be mapped to a pool of

local addresses.

Virtual Server

Using this feature, you can put PCs with public IPs and PCs with private

IPs in the same LAN area.

If you configure the BARRICADE as a virtual server, remote users

accessing services such as web or FTP at your local site via public IP

addresses can be automatically redirected to local servers configured with

private IP addresses. In other words, depending on the requested service

(TCP/UDP port number), the BARRICADE redirects the external service

request to the appropriate server (located at another internal IP address).

For example, if you set Type/Public Port to TCP/80 (HTTP or web) and

the Private IP/Port to 192.168.2.2/80, then all HTTP requests from

outside users will be transferred to 192.168.2.2 on port 80. Therefore, by

just entering the IP address provided by the ISP, Internet users can access

the service they need at the local address to which you redirect them.

The more common TCP service ports include: HTTP: 80, FTP: 21,

Telnet: 23, and POP3: 110. Click
