EATURES AND BENEFITS

Features and Benefits

• Internet connection to xDSL or cable modem via a 10/100 Mbps
WAN port

• Local network connection via 10/100 Mbps Ethernet ports

• DHCP for dynamic IP configuration, and DNS for domain name
mapping

• Firewall with Stateful Packet Inspection, client privileges,
intrusion detection, VPN, and NAT

• NAT also enables multi-user access with a single-user account,
and virtual server functionality (providing protected access to
Internet services such as Web, FTP, mail and Telnet)

• Supports VPN (Virtual Private Network) tunneling with IPSec and
PPTP

• User-definable application sensing tunnel supports applications
requiring multiple connections

• Easy setup through a Web browser on any operating system
that supports TCP/IP

• Compatible with all popular Internet applications

1-2

Applications

Many advanced applications are provided by the Barricade Plus, such
as:

• LAN Access

The Barricade Plus provides connectivity to 10/100 Mbps
devices, making it easy to create a network in small offices or
homes.

• Internet Access

This device supports Internet access through an xDSL, or Cable
connection. Since many DSL providers use PPPoE to establish
communications with end users, the Barricade Plus includes a
built-in client for this protocol, eliminating the need to install
this service on your computer.

• Shared IP Address

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

I

NTRODUCTION

•Virtual Server

If you have a fixed IP address, you can set up the Barricade Plus
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 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.

1-3

A

PPLICATIONS

• DMZ Host Support

Allows a networked computer to be fully exposed to the
Internet. This function is used when the special application
sensing tunnel feature is insufficient to allow an application to
function correctly.

• Security

The 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 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

Stateful Packet Inspection (SPI) is one of the firewall features
provided by the Barricade Plus. The SPI ensures that the data coming
into your network was requested by an end node computer on your
network. The 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 the incoming traffic is
allowed. If no match is found the incoming traffic is discarded.

• Virtual Private Network (VPN)

The Barricade Plus supports two of the most commonly used
VPN protocols – PPTP and IPSec. These protocols allow remote
users to establish a secure connection to their corporate network.
If your service provider supports VPNs, then any of 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 Plus are briefly described below.

• 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.

• IP Security – Provides IP network-layer encryption. IPSec
can support large encryption networks (such as the
Internet) by using digital certificates for device
authentication.

Description of Hardware

The Barricade Plus can be connected to the Internet or to a remote
site using its RJ-45 WAN port. It can be connected directly to your
PC or to a local area network using any of the Fast Ethernet LAN
ports.

Access speed to the Internet depends on your service type.
Full-rate ADSL can provide up to 8 Mbps downstream and 640
Mbps upstream. G.lite (or splitterless) ADSL provides up to 1.5
Mbps downstream and 512 Kbps upstream. Cable modems can
provide up to 36 Mbps downstream and 2 Mbps upstream. However,
you should note that the actual rate provided by specific service
providers may vary dramatically from these upper limits.

Although access speed to the Internet is determined by the modem
type connected to your Barricade Plus, data passing between
devices connected to your local area network can run up to
100 Mbps over the Fast Ethernet ports.

The Barricade Plus includes an LED display on the front panel for
system power and port indications that simplifies installation and
network troubleshooting. It also provides 4 RJ-45 LAN ports on the
front panel, as well as one RJ-45 WAN port on the rear panel.

I

NSTALLATION

• 4 RJ-45 ports for connection to a 10BASE-T/100BASE-TX
Ethernet Local Area Network (LAN). These ports can auto­negotiate the operating speed to 10/100 Mbps, the mode to
half/full duplex, and the pin signals to MDI/MDI-X (i.e.,
allowing these ports to be connected to any network device
with straight-through cable). These ports can be connected
directly to a PC or to a server equipped with an Ethernet
network interface card, or to a networking device such as an
Ethernet hub or switch.

• One RJ-45 port for connection to an xDSL or cable modem. This
port is fixed at 10/100 Mbps, full duplex. This port only
supports MDI-X pin signals, so you will have to use either
straight- through or crossover cable depending on the port type
used on the modem.

Attach to Your Network Using Ethernet Cabling

The 4 LAN ports on the Barricade Plus can auto-negotiate the
connection speed to 10 Mbps Ethernet or 100 Mbps Fast Ethernet,
as well as the transmission mode to half-duplex or full-duplex. These
LAN ports support auto-configuration for pin signals (auto-MDI/
MDI-X) that allow you to use straight-through cabling for connecting
the Barricade Plus to any network device. (See Appendix B for details
on wiring.)

Use twisted-pair cabling to connect any of the 4 LAN ports on the
Barricade Plus to an Ethernet adapter on your PC. Otherwise, you
can cascade any of LAN ports on the Barricade Plus to an Ethernet
hub or switch, and then connect your PC or other network
equipment to the hub or switch. When inserting an RJ-45 plug, be
sure the tab on the plug clicks into position to ensure that it is
properly seated.
