Configuring the Wireless Barricade Router

LAN

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

for the Wireless Barricade 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 Wireless Barricade
in the client address pool. Also remember to configure your client
PCs for dynamic IP address allocation.

Advanced Setup

Wireless

To configure the Wireless Barricade as a wireless access point
for wireless clients (either stationary or roaming), all you need to
do is define the radio channel, the Service Set identifier (SSID),
and encryption options.

Channel and SSID

You must specify a common radio channel and SSID (Service
Set ID) to be used by the Wireless Barricade and all of your
wireless clients. Be sure you configure all of your clients to the
same values.

ESSID: The Service Set ID. This should be set to the same value
as other wireless devices in your network. (Default: SMC.)

Note: The SSID is case sensitive and can consist of up to 32

alphanumeric characters.

Configuring the Wireless Barricade Router

Transmission Rate: Set the data rate transmitted

from the Wireless Barricade. The lower the data
rate, the longer the transmission distance.
(Default: Fully Automatic.)

Basic Rate: The highest rate specified is the rate the
Wireless Barricade will use when transmitting
broadcast/multicast and management frames.
Available options are: 1, 2, 5.5, and 11Mbps.
(Default: 2Mbps.)

Channel: The radio channel through which the Wireless
Barricade communicates with PCs in its BSS.
(Default: Auto)

Note: The available channel settings are limited by local

regulations.

Encryption

If you are transmitting sensitive
data across wireless channels,
you should enable Wired
Equivalent Privacy (WEP)
encryption. Encryption requires you to use the same set of
encryption/decryption keys for the Wireless Barricade and all of
your wireless clients. You can choose between standard 64-bit or
the more robust 128-bit encryption.

46

Advanced Setup

You may automatically generate encryption keys or manually
enter the keys. For automatic 64-bit security, enter a passphrase
and click Generate. Four keys will be generated (as shown
below). Choose a key from the dropdown list or accept the
default key. Automatic 128-bit security generates a single key.

47

Configuring the Wireless Barricade Router

If you use encryption, configure the same keys used for the
Wireless Barricade on each of your wireless clients. Note that
Wired Equivalent Privacy (WEP) protects data transmitted
between wireless nodes, but does not protect any transmissions
over your wired network or over the Internet.

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 Wireless Barricade’s firewall. This
section can be used to support several Internet based
applications such as VPN

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.

48

Advanced Setup

Virtual Server

If you configure the Wireless 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 Wireless 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.

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.

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

Advanced Setup

Firewall

the Wireless Barricade 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.
