NTRODUCTION

Congratulations on your purchase of the 802.11n ADSL2 BarricadeTM, hereafter referred to as the “Barricade”. 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. It is simple to configure and can be up and running in minutes.

The Barricade is compliant with the next generation IEEE 802.11n draft v2.0 specification while maintaining full backwards compatibility with the current 802.11b/g standards.

802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input multiple-output). MIMO uses multiple transmitter and receiver antennas to allow for increased data throughputs for up to 300 Mbps.

This provides sufficient bandwidth to stream HD video, listen to digital music, play online games, transfer large files, make VoIP calls and surf the Internet simultaneously.

1-1

Features and Benefits

• Intergrated ADSL modem for connecting to ADSL line

• Fully backward compatible with 802.11 g/802.11 b networks

• Wireless speeds up to 300 Mbps.

• Increased speed and coverage - up to 5 times the speed of 802.11g

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

• DHCP for dynamic IP configuration, and DNS Proxy/Relay 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, e-mail, and Telnet)

NTRODUCTION

• 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 the Barricade:

• Wired and Wireless LAN

The Barricade provides connectivity to 10/100 Mbps devices, and wireless connection speed up to 300 Mbps. This router is fully compliant with specifications defined in IEEE 802.11b, IEEE

802.11g and IEEE 802.11n draft v2.0 standards, 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 DSL providers use PPPoE 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

PPLICATIONS

Using only one ISP account, multiple users on your network can access the Internet 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.

1-3

NTRODUCTION

• 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.

• 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.

DNS

A Domain Name Server (DNS) is an index of IP addresses and Web addresses. If you type a Web address into your browser, such as www.smc.com, a DNS server will find that name in its index and find the matching IP address: xxx.xxx.xxx.xxx. Most ISPs provide a DNS server for speed and convenience. Since your Service Provider may connect to the Internet with dynamic IP settings, it is likely that the DNS server IP's are also provided dynamically. However, if there is a DNS server that you would rather use, you need to specify the IP address here.

ONFIGURING THE BARRICADE

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.

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.

endless retransmission of data traffic.

Authentication Required • None: No authentication.

• Password: A password authentication key is included in the packet. If this does not match what is expected, the packet will be discarded. This method provides very little security as it is possible to learn the authentication key by watching RIP packets.

• MD5: An a lgori thm that is used t o verify data integrity through the creation of a 128-bit message digest from data input (which may be a message of any length) that is claimed to be as unique to that specific data as a fingerprint is to a specific individual.

Authentication Code Password or MD5 Authentication key.

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.

Firewall

The Barricade Router’s firewall inspects packets at the application layer, maintains TCP and UDP session information including time-outs and the 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-of-Service (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. (For details see page 4-60.)

The firewall does not significantly affect system performance, so we advise enabling the function to protect your network.

Intrusion Detection

• Intrusion Detection Feature

Stateful Packet Inspection (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 in the Stateful Packet Inspection section.

RIP Defect (Default: Enabled) — If an RIP request packet is not acknowledged 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 from accumulating.

Discard Ping to WAN (Default: Disabled) — Prevent a ping on the Barricade’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.

Stateful Packet Inspection allows you to select different application types that are using dynamic port numbers. If you wish to use the Stateful Packet Inspection (SPI) to block 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, H.323 Service, or TFTP Service.
