COMPLIANCES
FCC - Class B
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that the interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected
• Consult the dealer or an experienced radio/TV technician for help
FCC Caution: To assure continued compliance, (example - use only shielded interface cables
when connecting to computer or peripheral devices). Any changes or modifications not
expressly approved by the party responsible for compliance could void the user’s authority to
operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
CAUTION STATEMENT:
FCC RF Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a minimum
distance of 20 centimeters between the radiator and your body. This transmitter must not be
co-located or operating in conjunction with any other antenna or transmitter.

I NTRODUCTION
Congratulations on your purchase of a Barricade™Wireless Cable/DSL
Broadband Router. SMC is proud to provide you with a powerful yet
simple communication device for connecting your local area network
(LAN) to the Internet. For those who want to surf the Internet at the
lowest possible cost, the Wireless Barricade™ is the convenient, easy
solution.
About the Wireless Barricade
The Wireless Barricade provides Internet access to multiple users by
sharing a single-user account. The Wireless Barricade features a
WAN
interface that allows you to connect either a DSL or cable
modem. The
Wireless Barricade provides extensive firewall protection and Virtual
Private Network (VPN) services.
The Wireless Barricade provides many cost-effective functions and
management benefits. It is simple to configure and can be up and running
in minutes.

I NTRODUCTION
1-2
Features and Benefits
• Internet connection to DSL or cable modem via a 10/100 Mbps WAN
port
• Local network connection via 10/100 Mbps Ethernet ports or
11 Mbps wireless interface (supporting up to 128 mobile users)
• 802.11b Compliant – interoperable with multiple vendors
• Provides seamless roaming within 802.11b WLAN environment
• DHCP for dynamic IP configuration, and DNS for domain name
mapping
• Firewall with Stateful Packet Inspection, client privileges, hacker
prevention, DoS, 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, mail, FTP, and Telnet)
• Virtual Private Network support using PPTP, L2TP, or IPSec
pass-through
• User-definable application sensing tunnel supports applications
requiring multiple connections
• Parental controls allows the user to limit certain web sites
• Email alerts when the users network is being compromise
• Easy setup through a web browser on any operating system that
supports TCP/IP
• Compatible with all popular Internet applications

I NTRODUCTION
1-3
Applications
Many advanced applications are provided by the Wireless Barricade, such as:
• LAN Access
The Wireless Barricade 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 a DSL or cable
connection. Since many DSL providers use PPPoE to establish
communications with end users, the Wireless Barricade includes a
built-in client for this protocol, eliminating the need to install this
service on your computer.
• Shared IP Address
The Wireless Barricade shares a single IP address with up to 253
users. Using only one ISP account, multiple users on your network
can simultaneously browse the Internet.
•VirtualServer
If you have a static IP address, you can set up the Wireless Barricade
to act as a virtual host for network address translation. Remote users
access various services at your site using the static IP address. Then,
depending on the requested service (or port number), the Wireless
Barricade routes the request to the appropriate server (at an internal
network IP address). This secures your network from direct attack by
hackers, and provides more flexible management by allowing you to
change internal network IP addresses without affecting outside access
to your network.

I NTRODUCTION
1-4
• User-Definable Application Sensing Tunnel
You may define special applications that require multiple connections
such as Internet gaming, video conferencing, and Internet telephony.
The Wireless Barricade will then sense the application type and open a
multi-port tunnel for it.
• DMZ Hosts 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 Wireless Barricade supports security features that deny Internet
access to specified users, or drop requests for specific services. The
Wireless 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.
• Virtual Private Network
The Wireless 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 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 Wireless
Barricade are briefly described below.

I NTRODUCTION
1-5
• 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.
• Layer Two Tunneling Protocol – Includes most of the features
provided by PPTP, but has less overhead and is more suited for
managed networks.
• IP Security – Provides IP network-layer encryption. IPSec can
support large encryption networks (such as the Internet) by using
digital certificates for device authentication.

Please fill out and return the Warranty Registration Card to SMC, or
register on SMC’s web site atwww.smc-europe.com. The Wireless Barricade
Broadband Router is covered by a limited lifetime warranty.
Hardware Description
The Wireless Barricade Broadband Router may be connected to the
Internet or to a remote site using its RJ-45 WAN port. It may be
connected directly to your PC or to a local area network using any of the
four 10/100 autosensing switch ports.
These RJ-45 ports auto-negotiate the operating speed (10/100 Mbps) and
the duplex mode (half/full duplex).
Access speed to the Internet depends on your service type. Full-rate
Asymmetric Digital Subscriber Line (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; Cable
modems 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.
Though Internet access speed is determined by the modem type
connected to your Wireless Barricade, data passing between devices
connected to your local area network can run up to 100 Mbps over the
Fast Ethernet ports.
The Wireless Barricade includes LED indicators on the front panel that
simplify installation and network troubleshooting.
