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 FEATURES 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 INTRODUCTION 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. 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 APPLICATIONS 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 Barricades 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. 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 ISPs 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. 1-4 CHAPTER 2 INSTALLATION Before installing the Barricade, verify that you have all the items listed under Package Contents. If any of the items are missing or damaged, contact your local distributor. Also be sure that you have all the necessary cabling before installing the Barricade.

This section allows you to configure wireless security settings according to your environment and the privacy level required. To configure your firewall settings, click Firewall in the left-hand menu. 4-27 CONFIGURING THE BARRICADE Firewall The Barricades 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. (See Intrusion Detection on page 4-35 for details.) The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network. Enable the firewall feature, and click Save Settings to proceed. 4-28 SECURITY Schedule Rule The first item listed in the Firewall section is Schedule Rule.

Click Save Settings to proceed, or Cancel to change your settings. 4-34 SECURITY Intrusion Detection The Barricades firewall inspects packets at the application layer, maintains TCP and UDP session information including timeouts and number of active sessions, and provides the ability to detect and prevent certain types of network attacks such as Denial-of-Service (DoS) attacks. 4-35 CONFIGURING THE BARRICADE Network attacks that deny access to a network device are called 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 DoS attacks including: Ping of Death (Ping flood) attack, SYN flood attack, IP fragment attack (Teardrop Attack), Brute-force attack, Land Attack, IP Spoofing attack, IP with zero length, TCP null scan (Port Scan Attack), UDP port loopback, Snork Attack. Note: The firewall does not significantly affect system performance, so we advise enabling the prevention features to protect your network. 4-36 SECURITY The table below lists the Intrusion Detection parameters and their descriptions. Parameter Intrusion Detection Feature Defaults Description SPI and Anti-DoS firewall protection No The Intrusion Detection feature of the Barricade limits the access of incoming traffic at the WAN port. When the Stateful Packet Inspection (SPI) feature is turned on, all incoming packets are blocked except those types marked with a check in the SPI section at the top of the screen. RIP Defect Discard Ping to WAN Disabled If the router does not reply to an IPX RIP request packet, 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. Prevents a ping on the routers WAN port from being routed to the network. Dont discard 4-37

CONFIGURING THE BARRICADE Parameter Stateful Packet Inspection When hackers attempt to enter your network, we can alert you by email Your E-mail Address SMTP Server Address POP3 Server Address User Name 4-38 Defaults Description Enabled This option allows you to select different application types that are using dynamic port numbers. 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. Enter your email address. Enter your SMTP server address (usually the part of the email address following the @ sign). Enter your POP3 server address (usually the part of the email address following the @ sign). Enter your email account user name. SECURITY Defaults Description Enter your email account password. 10 secs Configures the number of seconds that a packet state structure remains active.

To use WPA, your wireless network cards must be equipped with software that supports WPA. A security patch from Microsoft is available for free download (for XP only). Parameter Cipher Suite Authentication Description The security mechanism used in WPA for encryption. Select TKIP+AES (WPA/WPA2) or AES WPA2 Only. Select 802.1X or Pre-shared Key for the authentication method.

- 802.1X: for the enterprise network with a RADIUS server.

- Pre-shared key: for the SOHO network environment without an authentication server. Select the key type to be used in the Pre-shared Key. Type the key here. Pre-shared key type Pre-shared Key Group Key Re_Keying The period of renewing the broadcast/multicast key. 4-47 CONFIGURING THE BARRICADE 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). WPA and WPA2 Mode Types Enterprise Mode SOHO Mode WPA Authentication:

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 802.1X Authentication Enable or disable the authentication function. Session Idle Timeout Description 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) The interval time (in seconds) after which the client will be asked to re-authenticate. For example, if you set this to 30 seconds, the client will have to re-authenticate every 30 seconds. Set to 0 for no re-authentication.

(Default: 3600 seconds) This is the interval time (in seconds) for which the Barricade will wait between failed authentications.

(Default: 60 seconds) Sets the authentication server type. Set the IP address of your RADIUS server. Re-Authentication Period Quiet Period Server Type Server IP 4-49 CONFIGURING THE BARRICADE Parameter Server Port Secret Key NAS-ID Description Set the connection port that is configured on the radius server. The 802.1X secret key used to configure the Barricade. Defines the request identifier of the Network Access Server. The use of IEEE 802.1X offers an effective framework for authenticating and controlling user traffic to a protected network, as well as dynamically varying encryption keys. 802.1X ties EAP (Extensible Authentication Protocol) to both the wired and wireless LAN media and supports multiple authentication methods, such as token cards, Kerberos, one-time passwords, certificates, and public key authentication.

Note: Changing some of the device settings in the Advanced Settings mode may cause the Barricade to become unresponsive. The Barricades advanced management interface contains 6 main menu items as described in the following table. Menu NAT Description Shares a single ISP account with multiple users, sets up virtual servers. Maintenance Allows you to backup, restore, reset, and upgrade the Barricades System UPnP DNS DDNS Routing firmware. Sets the local time zone, the password for administrator access, the IP address of a PC that will be allowed to manage the Barricade remotely, and the IP address of a Syslog Server. Universal Plug and Play (UPnP) allows for simple and robust connectivity between external devices and your PC. Sets the IP address of a Domain Name Server. Dynamic DNS provides users on the Internet with a method to tie their domain name to a computer or server. Sets routing parameters and displays the current routing table. 4-51 CONFIGURING THE BARRICADE 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. 4-52 ADVANCED 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. Click Save Settings to proceed, or Cancel to change your settings. 4-53

CONFIGURING THE BARRICADE 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). 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. 4-54 ADVANCED SETTINGS Special Applications Some applications, such as Internet gaming, videoconferencing, Internet telephony and others, 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. Click the List of well known special applications link for more information. Specify the public port number normally associated with an application in the Trigger Port field. Set the protocol type to TCP or UDP, then enter the ports that the application requires. The ports may be in the format of a single port, or in a range, e.g., 72-96, or a combination of both. 4-55 CONFIGURING THE BARRICADE Popular applications requiring multiple ports are listed in the Popular Applications field. From the drop-down list, choose the application and then choose a row number to copy this data into. Note: Choosing a row that already contains data will overwrite the current settings. For a full list of ports and the services that run on them, see www.iana.org/assignments/port-numbers 4-56 ADVANCED SETTINGS NAT Mapping Table This page displays the current NAPT (Network Address Port Translation) address mappings. The NAT address mappings are listed 20 lines per page, click the control buttons to move forwards and backwards. As the NAT mapping is dynamic, a Refresh button is provided to refresh the NAT Mapping Table with the most updated values. The content of the NAT Mapping Table is described as follows:

Protocol - protocol of the flow. Local IP - local (LAN) hosts IP address for the flow. Local Port - local (LAN) hosts port number for the flow. Pseudo IP - translated IP address for the flow. Pseudo Port - translated port number for the flow. Peer IP - remote (WAN) hosts IP address for the flow. Peer Port - remote (WAN) hosts port number for the flow. 4-57 CONFIGURING THE BARRICADE Maintenance Use the Maintenance menu to back up the current settings, to restore previously saved settings, or to restore the factory default settings.

(holding it down for at least six seconds) to restore the factory defaults. The default password is smcadmin. Enter a maximum Idle Time Out (in minutes) to define a maximum period of time an inactive login session will be maintained. If the connection is inactive for longer than the maximum idle time, it will be logged out, and you will have to log in to the web management system again. Setting the idle time to 0, will mean the connection never times out.

(Default: 10 minutes) 4-63 CONFIGURING THE BARRICADE Remote Management By default, management access is only available to users on your local network. However, you can also manage the Barricade from a remote host by entering the IP address of a remote computer on this screen. Check the Enabled check box, and enter the IP address of the remote host and click Save Settings. Note: If you check Enabled and specify an IP address of 0.0.0.0, any host can manage the Barricade. For remote management via WAN IP address you need to connect using port 8080. Simply enter WAN IP address followed by :8080 in the address field of your web browser, for example, 212.120.68.20:8080. 4-64 Syslog Server SYSTEM The Syslog Server downloads the Barricade log file to the server with the IP address specified on this screen. Syslog servers offer the possibility to capture the live logs of the router on a PC. There are many shareware syslogs servers available on the web. (Default: Disabled) 4-65 CONFIGURING THE BARRICADE UPnP Universal Plug and Play technology makes home networking simple and affordable. This architecture offers pervasive peer-to-peer network connectivity of PCs of all form factors, intelligent appliances, and wireless devices. UPnP architecture leverages TCP/IP and the web to enable seamless proximity networking in addition to control and data transfer among networked devices in the home, office, and everywhere in between. Click Enable to turn on the Universal Plug and Play function of the Barricade. This function allows the device to automatically and dynamically join a network. Click Save Settings to proceed, or Cancel to change your settings. 4-66 DNS (DOMAIN NAME SERVER) DNS (Domain Name Server) Domain Name Servers are used to map a domain name

(e.g., www.somesite.com) to the equivalent numerical IP address

(e.g., 64.147.25.20). Your ISP should provide the IP address of one or more Domain Name Servers. Enter those addresses on this page. 4-67 CONFIGURING THE BARRICADE DDNS (Dynamic DNS) Dynamic DNS (DDNS) provides users on the Internet with a method to tie their domain name to the router or server. DDNS allows your domain name to follow your IP address automatically by having your DNS records changed when your IP address changes. (Default: Disabled) The DDNS service dynamically updates DNS information to a static hostname, provided by the DDNS service provider, as clients IP addresses change. Note: Please visit the web sites of the DDNS providers for details. DDNS Service Provider DynDNS.org TZO.com Web Site http://www.dyndns.org http://www.tzo.com For using DDNS, click on the enable radio button, select the DDNS Service type, and then enter the Domain Name, Account/E-mail address, and Password/Key. 4-68 ROUTING Routing This section defines routing related parameters, including static routes and RIP (Routing Information Protocol) parameters.

Subnet Mask Gateway Configure a static route. Enter the subnet mask of the remote network for which to set a static route. Enter the WAN IP address of the gateway to the remote network. Allows you to edit existing routes. Click Save Settings to save the configuration. 4-69 CONFIGURING THE BARRICADE RIP RIP sends routing-update messages at regular intervals and when the network topology changes. Parameter General RIP Parameters RIP mode Auto summary Description Globally enables or disables RIP. If Auto summary is disabled, then RIP packets will include sub-network information from all subnetworks connected to the router. If enabled, this sub-network information will be summarized to one piece of information covering all subnetworks. Table of current Interface RIP parameter Interface The WAN interface to be configured. Operation Mode Disable: RIP disabled on this interface. Enable: RIP enabled on this interface. Silent: Listens for route broadcasts and updates its route table. It does not participate in sending route broadcasts. 4-70

ROUTING Parameter Version Description Sets the RIP (Routing Information Protocol) version to use on this interface. Poison Reverse A method for preventing loops that would cause endless retransmission of data traffic. 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. Password Authentication key. Authentication Required Authentication Code 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. Click Save Settings to proceed, or Cancel to change your settings. 4-71 CONFIGURING THE BARRICADE Routing Table Click Routing Table to view the screen below. Parameter Flags Description Indicates the route status:

C = Direct connection on the same subnet. S = Static route. R = RIP (Routing Information Protocol) assigned route. I = ICMP (Internet Control Message Protocol) Redirect route. Network Address Destination IP address. Netmask The subnetwork associated with the destination. This is a template that identifies the address bits in the destination address used for routing to specific subnets. Each bit that corresponds to a 1 is part of the subnet mask number; each bit that corresponds to 0 is part of the host number. The IP address of the router at the next hop to which frames are forwarded. The local interface through which the next hop of this route is reached. When a router receives a routing update that contains a new or changed destination network entry, the router adds 1 to the metric value indicated in the update and enters the network in the routing table. Gateway Interface Metric 4-72 APPENDIX A TROUBLESHOOTING This section describes common problems you may encounter and possible solutions to them. The Barricade can be easily monitored through panel indicators to identify problems. Action Troubleshooting Chart Symptom LED Indicators Power LED is off Check connections between the Barricade, the external power supply, and the wall outlet. If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or external power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses, or surges at the power outlet. If you still cannot isolate the problem, then the external power supply may be defective. In this case, contact Technical Support for assistance. A-1 TROUBLESHOOTING Action Troubleshooting Chart Symptom LED Indicators LAN LED is Off Verify that the Barricade and attached device are powered on. Be sure the cable is plugged into both the Barricade and the corresponding device. Verify that the proper cable type is used and that its length does not exceed the specified limits. Be sure that the network interface on the attached device is configured for the proper communication speed and duplex mode. Check the adapter on the attached device and cable connections for possible defects. Replace any defective adapter or cable if necessary. Network Connection Problems Cannot ping the Barricade from the attached LAN, or the Barricade cannot ping any device on the attached LAN Verify that the IP addresses are properly configured. For most applications, you should use the Barricades DHCP function to dynamically assign IP addresses to hosts on the attached LAN. However, if you manually configure IP addresses on the LAN, verify that the same network address (network component of the IP address) and subnet mask are used for both the Barricade and any attached LAN devices. Be sure the device you want to ping (or from which you are pinging) has been configured for TCP/IP. A-2 TROUBLESHOOTING Action Troubleshooting Chart Symptom Management Problems Cannot connect using the web browser Forgot or lost the password Be sure to have configured the Barricade with a valid IP address, subnet mask, and default gateway.
