CHAPTER 6 | Navigating the Web-based Administration
The Barricade’s management interface features a Setup Wizard and an Advanced Setup section. Use
the Setup Wizard if you want to quickly setup the Barricade for use with a cable modem or DSL
modem. Advanced setup supports more advanced functions like hacker attack detection, IP and MAC
address filtering, intrusion detection, virtual server setup, virtual DMZ hosts, as well as other
advanced functions.
6.1 | Making Configuration Changes
Configurable parameters have a dialog box or a drop-down list. Once a configuration change has
been made on a page, be sure to click the “Apply” or “Next” button at the bottom of the page to
enable the new setting.
Note: To ensure proper screen refresh after a command entry, be sure that Internet Explorer 5.0 is
configured as follows: Under the menu “Tools/Internet Options/General/Temporary Internet
Files/Settings,” the setting for “Check for newer versions of stored pages” should be “Every visit to
the page.”

7004VBR –Manual
13
6.1 | Setup Wizard
Below is an outline of each option available from the Setup Wizard section. This wizard takes 3 steps
to complete an ISP configuration.
6.1.1 | Step One: Time Zone
The first step is to configure the Time Zone you are located in. This setting is used for accurate
timing of client filtering and log events.
6.1.2 | Step Two: Broadband Type
Select the type of broadband connection you have.
•Cable Modem
Your ISP may have given you a host name. If so, enter it into this field.
•Fixed-IP xDSL
Some xDSL Internet Service Providers may assign a fixed (static) IP address for your
gateway. If you have been provided with this information, choose this option and enter the
assigned IP address, subnet mask, gateway IP, and DNS IP addresses for the Barricade.

7004VBR –Manual
14
•PPPoE
Enter the PPPoE user name and password assigned by your Service Provider. The Service
Name is normally optional, but may be required by some service providers. Leave the
Maximum Transmission Unit (MTU) on the default value (1492) unless you have a particular
reason to change it. Enter a Maximum Idle Time (in minutes) to define a maximum period of
time for which the Internet connection is maintained during inactivity. If the connection is
inactive for longer than the Maximum Idle Time, it will be dropped. Enable the Auto-
reconnect option to automatically re-establish the connection as soon as you attempt to
access the Internet again.
•PPTP
Point-to-Point Tunneling Protocol is a common connection method used for xDSL connections
in Europe.
•BigPond®
The BigPond Internet service is used in Australia.
6.1.2 | Step Three: Finish Configuration
Once you have configured your type of ISP connection, simply click the [Finish] button and the
Barricade will automatically configure your Internet connection.

7004VBR –Manual
15
6.2 | Advanced Setup
Below is an outline of the Advanced Setup section. This section is used to manually configure your
ISP connection and also define the advanced system parameters, manage and control the Barricade
and its ports, or monitor network conditions.
6.2.1 | System
This section is used to configure the local time zone, password for administrator access, and the IP
address of a PC that will be allowed to manage the Barricade remotely.
•Time Zone
Use this option to configure the time zone for the Barricade. This information is used for log
entries and client access control.
There are 3 options to configure the Router’s internal clock:
oUsing preset or custom NTP servers
oUsing your computer system’s clock
oManually configure the Time and Date

7004VBR –Manual
16
•Password Settings
Use this menu to restrict access based on a password. By default, the password is
“smcadmin”.
NOTE: Passwords can contain up to 9 alphanumeric characters and are case sensitive.
•Remote Management
This feature allows a remote PC to configure, manage, and monitor the Barricade using a
standard web browser.
1. Check “Enable”
2. Set the “Allow Access” policy to one of the 2 options:
oAny IP Address –you can remotely manage the Barricade from any IP address on
the WAN side.
oSingle IP –you can only remotely managed the Barricade from this IP address on
the WAN side.
oIP Range –you can remotely manage the Barricade from any IP address in this
range.
3. Set the Remote Management Port to the port through which you want to remotely
access the Barricade.
NOTE: Do not set this for a port that is already in use. For example, if you are running
a web server on port 80, you can’t set the remote admin port to 80.

7004VBR –Manual
17
6.2.2 | WAN
Specify the WAN connection type provided by your Internet Service Provider, then click “More
Configuration” to enter detailed configuration parameters for the selected connection type.
•Dynamic IP
The Host Name is optional, but it may be required by some ISPs. The default MAC address is
set to the WAN’s physical interface on the Barricade. Use this address when registering for
Internet service, and do not change it unless required by your ISP. If your ISP used the MAC
address of an Ethernet card as an identifier when first setting up your broadband account,
connect only the PC with the registered MAC address to the Barricade and click the “Clone
MAC Address” button. This will replace the current Barricade MAC address with the already
registered Ethernet card MAC address.
If you are unsure of which PC did the broadband technician originally set up, call your ISP
and request they register a new MAC address for your account. Register using the
Barricade’s MAC address.

7004VBR –Manual
18
•PPPoE
Enter the PPPoE user name and password assigned by your Service Provider. The Service
Name is normally optional, but may be required by some service providers. The MTU
(Maximum Transmission Unit) governs the maximum size of the data packets. Leave this on
the default value (1492) unless you have a particular reason to change it.
Enter a Maximum Idle Time (in minutes) to define a maximum period of time for which the
Internet connection is maintained during inactivity. If the connection is inactive for longer
than the Maximum Idle Time, it will be dropped. Enable the Auto-reconnect option to
automatically re-establish the connection when an application attempts to access the
Internet again.
•PPTP
Point-to-Point Tunneling Protocol (PPTP) allows the secure remote access over the Internet
by simply dialing in a local point provided by an ISP. Using the above screen allows client PCs
to establish a normal PPTP session and provides hassle-free configuration of the PPTP client
on each client PC.

7004VBR –Manual
19
•Static IP Address
If your Internet Service Provider has assigned a fixed IP address to you, enter the assigned
address and subnet mask for the Barricade, and then enter the gateway address of your ISP.
You may need a fixed address if you want to provide Internet services, such as a web server,
or FTP server.
•BigPond®
Use this section to configure the built-in client.

7004VBR –Manual
20
•DNS
Domain Name Servers map numerical IP addresses to the equivalent domain name (e.g.,
www.smc.com). Your ISP should provide the IP address of one or more domain name
servers. Enter those addresses on this screen.
6.2.3 | LAN
From this section, you can configure the TCP/IP configuration for the Barricade LAN interface and
DHCP clients.
•LAN IP
Use the LAN menu to configure the LAN IP address for the Barricade and to enable the DHCP
server for dynamic client addresses 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).
In this example, the IP addresses run from 192.168.2.100 to 192.168.2.199 which 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.
NOTE: Do not include the address of the Barricade in the DHCP client address pool.
