NTRODUCTION
Congratulations on your purchase of the ADSL2 BarricadeTM, hereafter
referred to as the “Barricade”. 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.
It is simple to configure and can be up and running in minutes.
Features and Benefits
1
• Intergrated ADSL modem for connecting to ADSL line
• Local network connection via four 10/100 Mbps Ethernet ports
• DHCP for dynamic IP configuration, and DNS Proxy/Relay 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

NTRODUCTION
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:
•Wired LAN
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 an ADSL 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
Using only one ISP account, multiple users on your network can
access the Internet at the same time.
1-2
A
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.
• 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 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.
• 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.
1-3
I
NTRODUCTION
• Point-to-Point Tunneling Protocol — Provides a secure tunnel
• L2TP merges the best features of PPTP and L2F — Like PPTP,
• IP Security — Provides IP network-layer encryption. IPSec can
for remote client access to a PPTP security gateway. PPTP
includes provisions for call origination and flow control required
by ISPs.
L2TP requires that the ISP’s routers support the protocol.
support large encryption networks (such as the Internet) by using
digital certificates for device authentication.

• Do not place the Barricade in a dusty or wet environment.
You should also remember to turn off the power, remove the power cord
from the outlet, and keep your hands dry when you install the Barricade.
Connect the ADSL Line
Connect the supplied ADSL cable from the port labelled ADSL on the
Splitter/Microfilter to the ADSL port on your Barricade. When inserting
the plug, be sure the tab on the plug clicks into position to ensure that it is
properly seated.
Note: The ADSL port of SMC7904BRA2 is RJ-11. The ADSL port of
SMC7904BRB2 is RJ-45.

NSTALLATION
Attach to Your Network Using Ethernet Cabling
The four LAN ports on the Barricade auto-negotiate the connection speed
to 10 Mbps or 100 Mbps, as well as the transmission mode to half duplex
or full duplex.
Use RJ-45 cables to connect any of the four LAN ports on the Barricade
to an Ethernet adapter on your PC. Otherwise, cascade any of the LAN
ports on the Barricade 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 connector, be sure the tab on the connector clicks into position
to ensure that it is properly seated.
Warning: Do not plug a phone jack connector into an RJ-45 port. This
may damage the Barricade.
Note: Use 100-ohm shielded or unshielded twisted-pair cable with RJ-45
connectors for all Ethernet ports. Category 5 cable is
recommended. Make sure each twisted-pair cable length does not
exceed 100 meters (328 feet).
Connect the Power Adapter
Plug the power adapter into the power socket on the rear of the Barricade,
and the other end into a power outlet.
Check the power indicator on the front panel is lit. If the power i
not lit, refer to
In case of a power input failure, the Barricade will automatically restart and

A Domain Name Server (DNS) is an index of IP addresses and Web
addresses. If you type a Web address into your browser, such as
www.smc.com, a DNS server will find that name in its index and find the
matching IP address: xxx.xxx.xxx.xxx. Most ISPs provide a DNS server
for speed and convenience. Since your Service Provider may connect to
the Internet with dynamic IP settings, it is likely that the DNS server IP's
are also provided dynamically. However, if there is a DNS server that you
would rather use, you need to specify the IP address here.

ONFIGURATION PARAMETERS
Virtual Server
If you configure the Barricade as a virtual server, remote users accessing
services such as web or FTP at your local site via public IP addresses can
be automatically redirected to local servers configured with private IP
addresses. In other words, depending on the requested service (TCP/UDP
port number), the Barricade redirects the external service request to the
appropriate server (located at another internal IP address).
For example, if you set Type/Public Port to TCP/80 (HTTP or web) and
the Private IP/Port to 192.168.2.2/80, then all HTTP requests from
outside users will be transferred to 192.168.2.2 on port 80. Therefore, by
just entering the IP address provided by the ISP, Internet users can access
the service they need at the local address to which you redirect them.
The more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110.
A list of ports is maintained at the following link:

• Password: A password authentication key is
included in the packet. If this does not match
what is expected, the packet will be discarded.
This method provides very little security as it
is possible to learn the authentication key by
watching RIP packets.
• MD5: An algorithm that is used to verify data
integrity through the creation of a 128-bit
message digest from data input (which may
be a message of any length) that is claimed to
be as unique to that specific data as a
fingerprint is to a specific individual.
RIP sends routing-update messages at regular intervals and when the
network topology changes. When a router receives a routing update that
includes changes to an entry, it updates its routing table to reflect the new
route. RIP routers maintain only the best route to a destination. After
updating its routing table, the router immediately begins transmitting
routing updates to inform other network routers of the change.

FIREWALL
The Barricade Router’s firewall inspects packets at the application layer,
maintains TCP and UDP session information including time-outs and the
number of active sessions, and provides the ability to detect and prevent
certain types of network attacks.
Network attacks that deny access to a network device are called
Denial-of-Service (DoS) attacks. DoS attacks are aimed at devices and
networks with a connection to the Internet. Their goal is not to steal
information, but to disable a device or network so users no longer have
access to network resources.
The Barricade protects against the following DoS attacks: 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.
(For details see page 4-49.)
The firewall does not significantly affect system performance, so we advise
enabling the function to protect your network.

Intrusion Detection
• Intrusion Detection Feature
Stateful Packet Inspection (SPI) and Anti-DoS firewall protection
(Default: Enabled) — The Intrusion Detection Feature of the Barricade
Router limits access for incoming traffic at the WAN port. When the SPI
feature is turned on, all incoming packets will be blocked except for those
types marked in the Stateful Packet Inspection section.
RIP Defect (Default: Enabled) — If an RIP request packet is not
acknowledged to by the router, it will stay in the input queue and not be
released. Accumulated packets could cause the input queue to fill, causing
severe problems for all protocols. Enabling this feature prevents the
packets from accumulating.
Discard Ping to WAN (Default: Disabled) — Prevent a ping on the
Barricade’s WAN port from being routed to the network.

ONFIGURATION PARAMETERS
• Stateful Packet Inspection
This is called a “stateful” packet inspection because it examines the
contents of the packet to determine the state of the communications; i.e., it
ensures that the stated destination computer has previously requested the
current communication. This is a way of ensuring that all communications
are initiated by the recipient computer and are taking place only with
sources that are known and trusted from previous interactions. In addition
to being more rigorous in their inspection of packets, stateful inspection
firewalls also close off ports until connection to the specific port is
requested.
When particular types of traffic are checked, only the particular type of
traffic initiated from the internal LAN will be allowed. For example, if the
user only checks “FTP Service” in the Stateful Packet Inspection section,
all incoming traffic will be blocked except for FTP connections initiated
from the local LAN.
Stateful Packet Inspection allows you to select different application types
that are using dynamic port numbers. If you wish to use the Stateful Packet
Inspection (SPI) to block packets, click on the Yes radio button in the
“Enable SPI and Anti-DoS firewall protection” field and then check the
inspection type that you need, such as Packet Fragmentation, TCP
Connection, UDP Session, FTP Service, H.323 Service, or TFTP Service.
