The Barricade provides Internet access to multiple users by sharing a single-user account. Support is provided for both wired and wireless devices. New technology provides wireless security via Wired Equivalent Privacy (WEP) encryption and MAC address filtering. It is simple to configure and can be up and running in minutes.

Features and Benefits

• Internet connection to a DSL modem via an RJ-45 10/100 Mbps WAN port

• Local network connection via four 10/100 Mbps Ethernet ports

• On-board IEEE 802.11b 11 Mbps wireless network adapter

• DHCP for dynamic IP configuration, and DNS for domain name mapping

1-1

NTRODUCTION

• 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 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:

• Wireless and Wired LAN

The Barricade provides connectivity to 10/100 Mbps devices, and wireless IEEE 802.11b compatible devices, making it easy to create a network in small offices or homes.

• Internet Access

This device supports Internet access through a DSL 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.

1-2

PPLICATIONS

• Shared IP Address

The Barricade provides Internet access for up to 253 users via a single shared IP address. Using only one ISP account, multiple users on your network can browse the Web at the same time.

• 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. WEP (Wired Equivalent Privacy), SSID, and MAC filtering provide security over the wireless network.

1-3

NTRODUCTION

• 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.

• Point-to-Point Tunneling Protocol — Provides a secure tunnel

for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs.

• L2TP merges the best features of PPTP and L2F — Like PPTP,

L2TP requires that the ISP’s routers support the protocol.

• IP Security — Provides IP network-layer encryption. IPSec can

support large encryption networks (such as the Internet) by using digital certificates for device authentication.

ARDWARE DESCRIPTION

Hardware Description

The Barricade contains an integrated DSL modem and connects to the Internet or to a remote site using its RJ-45 WAN port. It can be connected directly to your PC or to a local area network using any of the four Fast Ethernet LAN ports.

Access speed to the Internet depends on your service type. Full-rate ADSL provides up to 8 Mbps downstream and 640 kbps upstream. G.lite (or splitterless) ADSL provides up to 1.5 Mbps downstream and 512 kbps upstream. However, you should note that the actual rate provided by specific service providers may vary dramatically from these upper limits.

Data passing between devices connected to your local area network can run at up to 100 Mbps over the Fast Ethernet ports and 11 Mbps over the built-in wireless network adapter.

The Barricade includes an LED display on the front panel for system power and port indications that simplifies installation and network

troubleshooting. It also provides the following ports on the rear panel:

Attach to Your Network Using Ethernet Cabling

The four LAN ports on the Barricade auto-negotiate the connection speed to 10 Mbps Ethernet or 100 Mbps Fast Ethernet, as well as the transmission mode to half duplex or full duplex.

Use twisted-pair cabling 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.

Notes: 1. Use 100-ohm shielded or unshielded twisted-pair cable with

RJ-45 connectors for all Ethernet ports. Use Category 3, 4, or 5 for connections that operate at 10 Mbps, and Category 5 for connections that operate at 100 Mbps.

2. 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 begin to operate once the input power is restored.

If the Barricade is properly configured, it will take about 30 seconds to establish a connection with the ADSL service provider after powering up. During this time the Sync indicator will flash. After the ADSL connection has been established, the ADSL Sync LED will stay on.

Bridged data is encapsulated using the RFC1483 protocol to enable data transport.

• PPPoA: Point-to-Point Protocol over ATM is a method of encapsulating data for transmission to a far point.

• 1483 Routing: 1483 Routing allows a simple, low-cost connection to the Internet via a standard 10BASE-T port. The router looks up the network address for each packet seen on the LAN port. If the address is listed in the routing table as local, it is filtered. If the address is listed under the ADSL port, it is forwarded. Or if the address is not found, then it is automatically forwarded to the default router (i.e., the ADSL router at the head end).

Wireless

The Barricade also operates as a wireless-to-wired bridge, allowing wireless computers to access resources available on the wired LAN, and to access the Internet. To configure the Barricade as a wireless access point for wireless clients (either stationary or roaming), all you need to do is enable the wireless function, define the radio channel, the domain identifier, and the encryption options. Check Enable and click APPLY.

Encryption

If you are transmitting sensitive data across wireless channels, you should enable encryption. You must use the same set of encryption keys for the Barricade and all of the wireless clients. Choose between standard 64-bit WEP (Wired Equivalent Privacy) or the more robust 128-bit encryption.

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. Choose a key from the drop-down list or accept the default key. Automatic 128-bit security generates a single key.

Note: The passphrase can consist of up to 32 alphanumeric characters.

To manually configure the keys, enter five hexadecimal pairs of digits for each 64-bit key, or enter 13 pairs for the single 128-bit key. (A hexadecimal digit is a number or letter in the range 0-9 or A-F.)

Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet.

Mac Address Filtering

Client computers can be filtered using the unique MAC address of their IEEE 802.11 network card. To secure an access point using MAC address filtering, you must enter a list of allowed/denied client MAC addresses into the filtering table. (See “Finding the MAC address of a Network Card” on page 4-58.)

Parameter Description

Filtering

Disable Disables MAC address filtering.

Enable Enables MAC address filtering.

NAT

Some applications require multiple connections, such as Internet gaming, video-conferencing, and Internet telephony. These applications may not work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, use these pages to specify the additional public ports to be opened for each application.

Address Mapping

Allows one or more public IP addresses to be shared by multiple internal users. This also hides the internal network for increased privacy and security. 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 into the from field.

4-30

DVANCED SETUP

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.

4-31

ONFIGURING THE BARRICADE

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::

http://www.iana.org/assignments/port-numbers.

Note: The WAN interface should have a fixed IP address to best utilize

this function. If your ISP only provides dynamic IP addresses, a search for “free dynamic IP” on any major search engine will turn up tools that will allow you to use the same domain name even though your IP address changes each time you log into the ISP.

RIP

Routing Information Protocol (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.

Parameter Description

DVANCED SETUP

Firewall

The Barricade Router’s firewall inspects packets at the application layer, maintains TCP and UDP session information including time-outs and 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-ofService (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. (See “Intrusion Detection” on page 4-42 for details.)

The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network. Select Enable and click the APPLY button to open the Firewall submenus.

Intrusion Detection

4-42

DVANCED SETUP

• Intrusion Detection Feature

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 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) — Prevent a PING on the Gateway’s WAN port from being routed to the network.

• 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.

4-43
