Installing the Router

Hardware Description

The Barricade Router can be connected to the Internet or to a
remote site using its RJ-45 WAN port or RS-232 serial port. It can
be connected directly to your PC or to a local area network using
any of the Fast Ethernet LAN ports. It can also function as a print
server.

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.
ISDN can provide up to 128 Kbps when using two bearer
channels. PSTN analog connections can now run up to 56 Kbps.
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 Router, data passing
between devices connected to your local area network can run
up to 100 Mbps over the Fast Ethernet ports.

The Barricade Router 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, one RS-232
serial port and one parallel printer port on the rear
panel.Full-duplex communications allow data to be sent and
received simultaneously, doubling the effective throughput.

4

Hardware Description

• 4 RJ-45 ports for connection to a 10BASE-T/100BASE-TX

Ethernet Local Area Network (LAN). These ports can
auto-negotiate 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 a DSL or cable modem

(WAN). This port also auto-negotiates operating speed to
10/100 Mbps, the mode to half/full duplex, and the pin signals
to MDI/MDI-X.

• One RS-232 serial port to connect to an ISDN Terminal

Adapter (TA) or to a PSTN analog modem.

• One parallel printer port that can be connected to a printer.

This printer can then be shared by any LAN users.

42

Advanced Setup

• LAN IP – Use the LAN menu to configure the LAN IP address

for the Barricade Router and to enable the DHCP server for
dynamic client address allocation.

• Set a period for the lease time if required. For home networks

this may be set to Forever, which means there is no time limit
on the IP address lease.

• IP Address Pool – A dynamic IP start address may be

specified by the user, e.g. 192.168.2.100 (default value).
Once this start IP address has been assigned, IP addresses
running from 192.168.2.100 to 192.168.2.199 will be part of
the dynamic IP address pool. IP addresses from 192.168.2.2
to 192.168.2.99, and 192.168.2.200 to 192.168.2.254 will be
available as static IP addresses.

Remember not to include the address of the Barricade Router in
the client address pool. Also remember to configure your client
PCs for dynamic IP address allocation.

Network Address Translation (NAT)

From this section you can configure the Address Mapping, Virtual
Server, and Special Application features that provide control over
the port openings in the router’s firewall. This section can be
used to support several Internet based applications such as VPN

43

Configuring the Barricade Router

Address Mapping

Allows one or more public IP addresses to be shared by multiple
internal users. Enter the Public IP address you wish to share into
the Global IP field. Enter a range of internal IPs that will share the
global IP.

44

Advanced Setup

Virtual Server

If you configure the Barricade Router 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 Router 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.

45

Configuring the Barricade Router

Special Applications

Some applications, such as Internet gaming, videoconferencing,
Internet telephony and others, require multiple connections.
These applications cannot work with Network Address
Translation (NAT) enabled. If you need to run applications that
require multiple connections, use the following screen to specify
the additional public ports to be opened for each application.

Specify the public port number normally associated with an
application in the Trigger Port field. Set the protocol type to TCP
or UDP, then enter the ports that the application requires. The
ports may be in the format 7, 11, 57, or in a range, e.g., 72-96, or
a combination of both, e.g., 7, 11, 57, 72-96.

Popular applications requiring multiple ports are listed in the
Popular Applications field. From the drop-down list, choose the
application and then choose a row number to copy this data into.

Note: Choosing a row that already contains data will

overwrite the current settings.

46

Advanced Setup

For a full list of ports and the services that run on them, see
www.iana.org/assignments/port-numbers.

Firewall

The Barricade Plus firewall can provide access control of
connected client PCs, 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. The firewall does not significantly affect
system performance, so we advise leaving it enabled to protect
your network users.

Access Control

Using this option allows you to specify different privileges based
on IP address for the client PCs.

47

Configuring the Barricade Router

Note: Click on Add PC and define the appropriate settings for

client PC services (as shown in the following screen).

MAC Filtering Table

48

Advanced Setup

The MAC Filtering feature of the Barricade allows you to control
access to your network to up to 32 clients based on the MAC
(Media Access Control) Address of the client machine. This ID is
unique to each network adapter. If the MAC address is listed in
the table, that client machine will have access to the network.

URL Blocking

To configure the URL Blocking feature, use the table below to
specify the websites (www.somesite.com) and/or keywords you
want to filter on your network.

To complete this configuration, you will need to create or modify
an access rule in “Access Control” on page 47. To modify an
existing rule, click the Edit option next to the rule you want to
modify. To create a new rule, click on the Add PC option.

From the Access Control Add PC section check the option for

Intrusion Detection

Advanced Setup

51

Configuring the Barricade Router

• SPI and Anti-DoS firewall protection (Default: Enabled)

–The Barricade Router Intrusion Detection Feature 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 with a check in the Stateful
Packet Inspection section.

• RIP Defect (Default: Enabled) – If an RIP request packet is

not replied 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 accumulating.

• Discard Ping from WAN (Default: Disabled)

– Prevents a PING on the Gateway’s WAN port from being
routed to the network.

52

Advanced Setup

• 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,
and TFTP Service.

TROUBLESHOOTING

The information outlined in this section describes some useful
steps for getting your computer and Barricade router online.

Verify you are connected to the Barricade Router

If you are unable to access the Barricade’s web-based
administration pages then you may not be properly connected or
configured. The screen shots in this section were taken on a
Windows 2000 machine, but the same steps will apply to
Windows 95/98/Me/XP.

To determine your TCP/IP configuration status please follow the
steps below:

1. Click Start then choose Run.

2. Type cmd or command to open a DOS prompt.

3. In the DOS window, type ipconfig and verify the information

that is displayed.

4. If your computer is setup for DHCP, then your TCP/IP
configuration should be similar to the information displayed:

• IP Address: 192.168.2.X (x is number between 100 and 199)

• Subnet: 255.255.255.0

• Gateway: 192.168.2.1

83

Troubleshooting

If you have any other IP address information listed see below.

If you have an IP address that starts with 169.254.XXX.XXX then
see the next section.

If you have another IP address configured, then see section A.3

I am getting an IP Address that starts with 169.254.XXX.XXX

If you are getting this IP Address, then you need to check that
you are properly connected to the Barricade Router.

Confirm that you have a good link light on the Barricade for the
port this computer is connected to. If not, please try another
cable.

If you have a good link light, please open up a DOS window as
described in the previous section and type ipconfig/renew.

If you are still unable to get an IP Address from the Barricade,
reinstall your network adapter. Please refer to your adapter
manual for information on how to do this.

I have another IP Address displayed

If you have another IP address listed then the PC may not be
configured for a DHCP connection. Please refer to “Configuring

Client TCP/IP” on page 9 for information.

Once you have confirmed your computer is configured for DHCP,
then please follow the steps below.

1. Open a DOS window as described above.

2. Type ipconfig/release.

84

3. Then type ipconfig/renew.

Troubleshooting

Symptom

The 10/100 LED does not light after a connection is made.

Possible Solutions

• Check that the host computer and hub are both powered on.

• Be sure the network cable is connected to both devices.

• Verify that Category 5 cable is used if you are operating at

100 Mbps, and that the length of any cable does not exceed
100 m (328 ft).

85

Troubleshooting

• Check the network card connections.
