equivalent product, during the applicable warranty term. SMC will endeavor to repair or
replace any product returned under warranty within 30 days of receipt of the product.
The standard limited warranty can be upgraded to a Limited Lifetime* warranty by registering
new products within 30 days of purchase from SMC or its Authorized Reseller. Registration
can be accomplished via the enclosed product registration card or online via the SMC web
site. Failure to register will not affect the standard limited warranty. The Limited Lifetime
warranty covers a product during the Life of that Product, which is defined as the period of
time during which the product is an “Active” SMC product. A product is considered to be
“Active” while it is listed on the current SMC price list. As new technologies emerge, older
technologies become obsolete and SMC will, at its discretion, replace an older product in its
product line with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of discontinued
products with their respective dates of discontinuance can be found at:

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

I NTRODUCTION
Congratulations on your purchase of a Barricade™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
Barricade™ Broadband Router is the convenient, easy solution.
About the Barricade
The Barricade provides Internet access to multiple users by sharing a
single-user account. The Barricade features a
WAN interface that allows
you to connect either a DSL or cable
modem. The Barricade provides
extensive firewall protection and Virtual Private Network (VPN) services.
The Barricade provides many cost-effective functions and management
benefits. It is simple to configure and can be up and running in minutes.
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 switch ports
• DHCP for dynamic IP configuration, and DNS for domain name
mapping

I NTRODUCTION
1-2
• 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 Barricade, such as:
• LAN Access
The 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 Barricade includes a built-in
client for this protocol, eliminating the need to install this service on
your computer.
• Shared IP Address
The 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 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 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 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 Barricade supports security features that deny Internet access to
specified users, or drop requests for specific services. 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.
• Virtual Private Network
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 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 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.

I NSTALLATION
2-2
Please fill out and return the Warranty Registration Card to SMC, or
register on SMC’s web site at www.smc.com. The Barricade Broadband
Router is covered by a limited lifetime warranty.
Hardware Description
The 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 Barricade, data passing between devices connected to
your local area network can run up to 100 Mbps over the Fast Ethernet
ports.
The Barricade includes LED indicators on the front panel that simplify
installation and network troubleshooting.
