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.

20

7004VBR – Manual

• 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.

21

• 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

22

7004VBR – Manual

• 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.

23

7004VBR – Manual

6.2.4 | NAT

From this section, you can configure the 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 connections.

• Virtual Server
You can configure the Barricade as a virtual server. Remote users accessing services such as
the Web or FTP at your local site via public IP addresses can be automatically redirected to
local servers configured with private IP addresses. To provide the most flexibility, the
Barricade can support either a single port (80) or a range of ports (80-100). The traffic type
can also be defined as TCP, UDP, or both (UDP and TCP).

Some of the more common ports include: HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.

24

7004VBR – Manual

• Special Applications
Some applications, such as Internet gaming, videoconferencing, Internet telephony 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 port or port range normally associated with an application in the “Trigger Port”
field, select the protocol type as TCP or UDP, and then enter the public ports and data type
associated with the trigger port to open them for inbound traffic.

The maximum range that you can use for all NAT ports is 0 to 65535.

6.2.5 | Firewall

The firewall does not significantly affect system performance, so we advise enabling it to protect your
network users. To enable the Stateful Packet Inspection (SPI) firewall, click on “Advanced” under the
Firewall section and select “Enable” and click the “Apply” button.

The Barricade SPI firewall can provide the 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.

• Parental Control
Using this option allows you to specify different privileges for the client PCs. This is an
excellent tool to control a child’s access to specific content and/or general internet access for
a specific time and/or date.

To setup a Parental Control Rule: Click on “Click here to configure a new Parental
Control Rule” link. This will take you to the Rule Setup section.

25

7004VBR – Manual

Rule Description: Set a Rule Description so you know what this rule applies to. Ex. Jon’s
Internet Access.

DHCP Option: Apply this rule to a specific IP Address or range of IP’s on your network. You

can use the DHCP client list to quickly add IP addresses that were provided
via DHCP connections.

Schedule Rule: Set the time and date this rule is active. You can have this rule be active

all the time or configure it to only be active on set days and times.

You can pick the dates you want this rule to be active by checking the box
next to the date.

For time, set the start time you want the Rule to active, and then set how
long you want the rule to run.

26

7004VBR – Manual

• MAC Filtering
The MAC Filtering feature of the Barricade allows you to control access to your network
based on the MAC (Media Access Control) Address of the client machine. This ID is unique to
each network adapter.

You can configure that MAC address to be allowed to access your network, or to deny access
to the network.

This tool will also allow you to MAP DHCP IP Addresses to certain MAC Addresses. This tool
works well in conjunction with the Parental Control rules to provide maximum control.

27

• Website Blocking
The Website Blocking feature of the Barricade limits access to website domains (i.e.

• Advanced Settings
This section allows you to configure several advanced features for the Barricade Firewall.

The following features can be set on this page:

o Advanced Firewall Protection: Enable/Disable SPI section of firewall.

28

7004VBR – Manual

o Discard Ping from WAN: When this feature is enabled, any host on the WAN

cannot ping this product. This helps avoid unnecessary attacks from the WAN side
because your connection is invisible. It is recommended that you enable this option
for security.

o VPN Pass-through: Enable this option if you are using a PPTP, L2TP or IPSec VPN

connection.

o Email Alert: Configure this option if you want the Barricade to email when hackers

attempt to attack your network to a specific email address. You will need to
configure your email address, username and password, as well as a SMTP server to
send the mail through.

• DMZ (Demilitarized Zone)
If you have a client PC that cannot run an Internet application properly from behind the
firewall, then you can open the client PC up to unrestricted two-way Internet access. Enter
the LAN IP address of a DMZ host and click “Enable”.

NOTE: Adding a client to the DMZ (Demilitarized Zone) may expose your local network to a
variety of security risks. Only use this option as a last resort.

6.2.6 | DDNS (Dynamic DNS)

The Barricade has an integrated Dynamic DNS feature that provides users on the Internet a method
to tie their domain name(s) to computers or servers. DDNS allows your domain name to follow your
IP address automatically by having your DNS records changed when your IP address changes.

The section also has a “Server Configuration” section that automatically opens the port options
checked in the Virtual Server section. Simply enter in the IP Address of your server, such as a web
server, and then click on the port option HTTP Port 80 so users can access your server from the WAN
connection (Internet).

6.2.7 | UPnP

The Barricade supports UPnP (Universal Plug and Play), a networking architecture that provides
compatibility amongst networking equipment. This feature allows an UPnP based operating system,
like Windows XP to automatically communicate with the Barricade and open the required services
when needed.

APPENDIX A | Troubleshooting

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

A.1 | 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” (without the quotes) to open a DOS prompt.

3. In the DOS window, type “ipconfig” and verify the information that is displayed.

4. If you 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

If you have an IP address that starts with 169.254.XXX.XXX then see section A.2.

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

A.2 | 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’s port to which this computer is connected.
If not, please try another cable.

If you have a good link light, please open up a DOS window as described in section A.1 and type
“ipconfig /renew” (without the quotes)

If you are still unable to get an IP Address from the Barricade, reinstall your network adapter. Please
refer to your adapter manual for instructions.

A.3 | I have another IP Address displayed

32

7004VBR – Manual

If you have another IP address listed, then the PC may not be configured for a DHCP connection.
Please refer to Chapter 4 | Configure your Computer 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” (without the quotes)

3. Then type “ipconfig /renew” (without the quotes)

Once you are able to get a valid IP address from the Barricade Router, then you can now access
the web-based Administration pages.

If you still are not getting an IP address from the Barricade, please reset the router as outlined in
Chapter 2 and follow the steps outlined in this appendix again.

If you still cannot access the router once you have reset it, please contact SMC Technical
Support.

33

7004VBR – Manual

A.4 | I have a Dynamic IP connection and I can’t get online

Most cable companies use a Dynamic IP configuration to provide Internet access. If you have this
type of connection, and are unable to get connected, please follow the steps outlined below:

1. Unplug the power from your Cable or DSL modem for 2 mins.

2. Confirm that your Barricade router is configured for a Dynamic IP configuration

3. Plug the power back into your Modem.

4. Wait for your Modem to connect to the network, and then click on the status page of the
router to confirm that you are online.

The reason this process works is because certain broadband connections require a MAC address to
gain network access. This MAC address can be changed by following the above process to re-set the
approved MAC address to the MAC address of the Barricade router.
