Congratulations on your purchase of the BARRICADE 54Mbps g Wireless Broadband Router (SMCWBR14-G2). We are proud to provide you with a powerful yet simple communication device for connecting your local area network (LAN) to the Internet. For those who want to surf the Internet in the most secure way, this router provides a convenient and powerful solution.

About the BARRICADE

The BARRICADE provides Internet access to multiple users by sharing a single-user account. This new technology provides many secure and cost-effective functions. It is simple to configure and can be up and running in minutes.

1-1

EATURES AND BENEFITS

Features and Benefits

• Local network connection via a 10/100 Mbps Ethernet port

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

• 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, email, 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

1-2

Applications

Many advanced networking features are provided by this BARRICADE:

• Wired and Wireless LAN

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

• Internet Access

This device supports Internet access through an ADSL connection. Since many ADSL 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.

• 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.

NTRODUCTION

•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.

1-3

PPLICATIONS

• 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. WPA/WPA2, WEP, SSID, and MAC filtering provide security over the wireless network.

• Virtual Private Network (VPN Pass-through)

The BARRICADE supports three of the most commonly used VPN protocols – PPTP, L2TP, and IPSec. The VPN protocols supported by the BARRICADE are briefly described below.

1-4

• 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.

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 4-37 for details.)

If you wish to use Stateful Packet Inspection (SPI) for blocking 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 and TFTP Service.

It is called a “stateful” packet inspection because it examines the contents of the packet to determine the state of the communication; 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 a 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.

WPA

WPA addresses all known vulnerabilities in WEP, the original, less secure 40 or 104-bit encryption scheme in the IEEE 802.11 standard. WPA also provides user authentication, since WEP lacks any means of authentication. Designed to secure present and future versions of IEEE

802.11 devices, WPA is a subset of the IEEE 802.11i specification.

WPA replaces WEP with a strong new encryption technology called Temporal Key Integrity Protocol (TKIP) with Message Integrity Check (MIC). It also provides a scheme of mutual authentication using either IEEE 802.1X/Extensible Authentication Protocol (EAP) authentication or pre-shared key (PSK) technology. The passphrase can consist of up to 32 alphanumeric characters.

WPA2

Launched in September 2004 by the Wi-Fi Alliance, WPA2 is the certified interoperable version of the full IEEE 802.11i specification which was ratified in June 2004. Like WPA, WPA2 supports IEEE 802.1X/EAP authentication or PSK technology. It also includes a new advanced encryption mechanism using the Counter-Mode/CBC-MAC Protocol (CCMP) called the Advanced Encryption Standard (AES).

802.1X

If 802.1X is used in your network, then you should enable this function for the BARRICADE. This screen allows you to set the 802.1X parameters.

802.1X is a method of authenticating a client wireless connection. Enter the parameters below to connect the BARRICADE to the Authentication Server.

Parameter Description

802.1X Authentication Enable or disable the authentication function.

Session Idle Timeout This is the time (in seconds) that a session will sit inactive

before terminating. Set to 0 if you do not want the session to timeout. (Default: 300 seconds)

NAT

The first menu item in the Advanced Settings section is Network Address Translation (NAT). This process allows all of the computers on your home network to use one IP address. Using the NAT capability of the BARRICADE, you can access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP.

To use the NAT feature, check the Enable radio button and click Save Settings.

Address Mapping

Network Address Translation (NAT) allows IP addresses used in a private local network to be mapped to one or more addresses used in the public, global Internet. This feature limits the number of public IP addresses required from the ISP and also maintains the privacy and security of the local network. We allow one public IP address to be mapped to a pool of local addresses.

ONFIGURING THE

Virtual Server

Using this feature, you can put PCs with public IPs and PCs with private IPs in the same LAN area.

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).

BARRICADE

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. Click All known port number for more information about public service ports.
