Applications

Many advanced networking features are provided by the Barricade:

• Wireless and Wired LAN

The Barricade provides connectivity to wired 10/100 Mbps devices, and wireless IEEE 802.11b compatible devices, making it easy to create a network in small offices or homes.

• Internet Access

This device supports Internet access through a DSL connection. Since many DSL providers use PPPoE or PPPoA to establish communications with end users, the Barricade includes built-in clients for these protocols, eliminating the need to install these services on your computer.

• Shared IP Address

The Barricade provides Internet access for up to 253 users via a single shared IP address. Using only one ISP account, multiple users on your network can browse the Web at the same time.

PPLICATIONS

•Virtual Server

If you have a fixed IP address, you can set the Barricade to act as a virtual host for network address translation. Remote users access various services at your site using a constant IP address. Then, depending on the requested service (or port number), the Barricade 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.

1-3

NTRODUCTION

• DMZ Host Support

Allows a networked computer to be fully exposed to the Internet. This function is used when NAT and firewall security prevent an Internet application from functioning correctly.

• Security

The Barricade supports security features that deny Internet access to specified users, or filter all requests for specific services the administrator does not want to serve. The Barricade’s firewall also blocks 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. WEP (Wired Equivalent Privacy), SSID, and MAC filtering provide security over the wireless network.

• Virtual Private Network (VPN)

The Barricade supports three of the most commonly used VPN protocols – PPTP, L2TP, and IPSec. These protocols allow remote users to establish a secure connection to their corporate network. If your service provider supports VPNs, then these protocols can be used to create an authenticated and encrypted tunnel for passing secure data over the Internet (i.e., a traditionally shared data network). The VPN protocols supported by the Barricade are briefly described below.

1-4

• Point-to-Point Tunneling Protocol – Provides a secure tunnel for

remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs.

• L2TP merges the best features of PPTP and L2F. Like PPTP,

L2TP requires that the ISP’s routers support the protocol.

• IP Security – Provides IP network-layer encryption. IPSec can

support large encryption networks (such as the Internet) by using digital certificates for device authentication.

ARDWARE DESCRIPTION

Hardware Description

The Barricade contains an integrated DSL modem and connects to the Internet or to a remote site using its RJ-11 WAN port. It connects directly to your PC or to a local area network using any of the four RJ-45 Fast Ethernet LAN ports or via a wireless network adapter.

Access speed to the Internet depends on your service type. Full-rate ADSL provides up to 8 Mbps downstream and 640 Kbps upstream. G.lite (or splitterless) ADSL provides up to 1.5 Mbps downstream and 512 Kbps upstream. However, you should note that the actual rate provided by specific service providers may vary dramatically from these upper limits.

Data passing between devices connected to your local area network can run at up to 100 Mbps over the Fast Ethernet ports and 11 Mbps over the built-in wireless network adapter.

The Barricade includes an LED display on the front panel for system power and port indications that simplifies installation and network troubleshooting. It also provides the following ports on the rear panel:
