I NTRODUCTION
Congratulations on your purchase of the Barricade Wireless Broadband
Router with built-in ADSL Modem (SMC7404WBRA). We are 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 in the most secure way, this Router provides a
convenient and powerful solution.
About the Barricade
The Barricade provides Internet access to multiple users by sharing a
single-user account. Support is provided for both wired and wireless
devices. New technology provides wireless security via WEP (Wired
Equivalent Privacy) encryption and MAC address filtering. It is simple to
configure and can be up and running in minutes.
Features
• Internet connection via an RJ-11 WAN port.
• Local network connection via four 10/100 Mbps Ethernet ports.
• On-board IEEE 802.11b 11 Mbps wireless network adapter.
• DHCP for dynamic IP configuration, and DNS for domain name
mapping.
• Firewall with Stateful Packet Inspection, client privileges, intrusion
detection, and NAT.

• NAT also enables multi-user Internet access via a single user account,
and virtual server functionality (providing protected access to Internet
services such as Web, FTP, e-mail, and Telnet).
• VPN pass-through (IPSec-ESP Tunnel mode, L2TP, 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.
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 an ADSL connection.
Since many ADSL 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.

•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.
•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 that
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.
• 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.

System Requirements
You must meet the following minimum requirements:
• Internet access from your Internet Service Provider (ISP) using an
ADSL modem.
• A PC using a fixed IP address or dynamic IP address assigned via
DHCP, as well as a gateway server address and DNS server address
from your service provider.
• A computer equipped with a 10 Mbps, 100 Mbps, or 10/100 Mbps
Fast Ethernet card, a USB-to-Ethernet converter, or an IEEE 802.11b
wireless network adapter.

Hardware Description
The Barricade contains an integrated ADSL 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:
