CONFIGURATION PARAMETERS4-29Clone MAC AddressSome ISPs require you to register your MAC address with them. If this is the case, and you have previously registered the MAC address of another device, the MAC address of the Barricade must be changed to the MAC address that you have registered with your ISP.
CONFIGURING THE BARRICADE4-30DNSA 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.
CONFIGURATION PARAMETERS4-31LANThe LAN settings menu allows you to change the default IP address of the Barricade, modify the DHCP server settings. Parameter DescriptionLAN IPIP Address The IP address of the Barricade.IP Subnet Mask The subnet mask of the Barricade.DHCP Server This option allows you to enable or disable the DHCP server function. By default DHCP is enabled.Lease Time Allows you to select a pre-defined lease time for IP addresses assigned using DHCP. For home networks this may be set to Forever, which means there is no time limit on the IP address lease.IP Address PoolStart IP Address/End IP address Specify the start/end IP address of the DHCP pool. Do not include the gateway address of the Barricade in the client address pool. If you change the pool range, make sure the first three octets match the gateway’s IP address, i.e., 192.168.2.xxx.Domain Name If your network uses a domain name, enter it here. Otherwise, leave this field blank.
CONFIGURING THE BARRICADE4-32WirelessThe router also operates as a wireless access point, allowing wireless computers to communicate with each other. To configure this function, all you need to do is enable the wireless function, define the radio channel, the domain identifier, and the security options.• Enable or disable Wireless module function: select to enable or disable the wireless function.
CONFIGURATION PARAMETERS4-33Channel and SSIDYou must specify a common radio channel and SSID (Service Set ID) to be used by the router and all of its wireless clients. Be sure you configure all of its clients to the same values.Parameter DescriptionSSID This is the Service Set ID. The SSID must be the same on the router and all of its wireless clients. SSID Broadcast Select to enable/disable the brocasting of SSID. Enable this function for easy connection for the clients. Disable this function for increased security.Wireless Mode The Router supports 11n, 11g, and 11b wireless networks. SMC recommend using “Mixed 802.11n, 802.11g and 802.11b” to provide compatibility with 11n, 11g and 11b wireless clients.Channel This is the radio channel used for wireless communication.
CONFIGURING THE BARRICADE4-34Notes: 1. When bandwidth is set to 20 MHz, there would be no extension channel that can be selected. The extension channel is based on the main or primary channel. When the main channel is set to channel 1, channel 5 will be used as the extension channel. When the main channel is set to 9, the extension channel can be channel 5 or 13.2. The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end user. Bandwidth Select the bandwidth: •20 MHz: Sets the operation bandwidth as 20 MHz. when 20 MHz is selected, there would be no extension channel available.•20/40 MHz: Allows automatic detection of the operation bandwidth between 20 and 40 MHz. Choosing this mode allows you to use the extension channel.Extension Channel This is the optional channel for use. Setting the Bandwith to 20/40 MHz allows you to use this extension channel as the secondary channel for doubling the bandwith of your wireless network.Protected Mode In most situations, best performance is achieved with Protected Mode turning Off. If you are operating in an environment with heavy 802.11b traffic or interference, best performance may be achieved with Protected Mode turning On.802.11e/WMM QoS Select to turn on/turn off the QoS function. Parameter Description
CONFIGURATION PARAMETERS4-35Access ControlUsing the Access Control functionality, you can restrict access based on MAC address. Each PC has a unique identifier known as a Medium Access Control (MAC) address. With MAC filtering enabled, the computers whose MAC address you have listed in the filtering table will be able to connect (or will be denied access) to the router.• Enable MAC Filtering: select to enable or disable this function.• Access Rule for registered MAC address: select to allow/deny access for the registered MAC addresses. Selecting Allow means only MAC addresses registered here will be able to connect to the router. Selecting Deny means only the MAC addresses registered here will be denied access to the router.• Wireless DHCP Client List: use the drop down list to quickly copy the current entry to the table.• MAC Filtering Table: you can enter up to 32 stations to the table.

CONFIGURING THE BARRICADE4-40WPS (Wi-Fi Protected Setup)The Barricade was implemented with the ease-of-use Wi-Fi Protected Setup (WPS). WPS makes a secure wireless network much easier to achieve by using a PIN number and the Push Button Control (PBC).• Enable or disable WPS features: select to enable or disable.• Generate New PIN: click this button to create a new PIN. • Restore Default PIN: click this button to restore the PIN.Secret Key The secret key shared between the authentication server and its clients.NAS-ID Defines the request identifier of the Network Access Server.Parameter Description
CONFIGURATION PARAMETERS4-41PINEnter the PIN of the client device and click Start PIN. Then start WPS on the client device from it's wireless utility or WPS application within 2 minutes. Take the following steps for easy network security settings.1. Power on your client device supporting WPS PIN code method.2. Start WPS PIN process on client device. For instructions on how to do this refer to the client devices user manual.3. Enter the PIN code of client device. Note: The PIN code is generally printed on the bottom of the unit or displayed in the utility.4. Click the Start PIN button on the screen.
CONFIGURING THE BARRICADE4-42PBC (Push Button Configuration)To achieve successful WPS connection, you can use one of the following ways:(1) push and hold the WPS button on this router for 4 secondsor (2) click the Start PBC button on this screen.Now click the WPS button on the client device which you are connecting. Make sure the client device is powered on.Note: This connection procedure must be done within 2 minutes after pressing the WPS button on the router.
CONFIGURATION PARAMETERS4-43ManualFor client devices without the WPS function, you should manually configure the client device with the settings on this screen.
CONFIGURING THE BARRICADE4-44NATNetwork Address Translation (NAT) allows multiple users to access the Internet sharing one public IP. • Enable or disable NAT module function: select to enable or disable this function.
CONFIGURATION PARAMETERS4-45Address MappingAllows 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.
CONFIGURING THE BARRICADE4-46Virtual ServerIf 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.
CONFIGURATION PARAMETERS4-47Special Application 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 screens to specify the additional public ports to be opened for each application. • Use the Popular applications drop down menu to quickly copy the entry to the table.
CONFIGURING THE BARRICADE4-48NAT Mapping TableThis screen displays the current NAPT (Network Address Port Translation) address mappings. Click Refresh to update the table.
CONFIGURATION PARAMETERS4-49RoutingThese screens define routing related parameters, including static routes and RIP (Routing Information Protocol) parameters.Static Route Click Add to add a new static route to the list, or check the box of an already entered route and click Modify. Clicking Delete will remove an entry from the list.Parameter DescriptionIndex Check the box of the route you wish to delete or modify.Network Address Enter the IP address of the remote computer for which to set a static route.Subnet Mask Enter the subnet mask of the remote network for which to set a static route.Gateway Enter the WAN IP address of the gateway to the remote network.
CONFIGURING THE BARRICADE4-50RIP Parameter DescriptionGeneral RIP ParametersRIP mode Globally enables or disables RIP.Auto summary If Auto summary is disabled, then RIP packets will include sub-network information from all sub-networks connected to the router. If enabled, this sub-network information will be summarized to one piece of information covering all sub-networks. Table of current Interface RIP parameterInterface 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.Version Sets the RIP (Routing Information Protocol) version to use on this interface.
CONFIGURATION PARAMETERS4-51RIP 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.Poison Reverse A method for preventing loops that would cause 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 algorithm that is used to 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.Parameter Description
CONFIGURING THE BARRICADE4-52Routing Table Parameter DescriptionFlags 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 AddressDestination 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.Gateway The IP address of the router at the next hop to which frames are forwarded.Interface The local interface through which the next hop of this route is reached. Metric 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.
CONFIGURATION PARAMETERS4-53FirewallThe 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. Select Enable and click the SAVE SETTINGS button.
CONFIGURING THE BARRICADE4-54Access ControlAccess Control allows users to define the outgoing traffic permitted or not-permitted through the WAN interface. The default is to permit all outgoing traffic. Parameter DescriptionEnable Filtering FunctionEnable or Disable Access control function. Normal Filtering TableDisplays descriptive list of filtering rules defined.
CONFIGURATION PARAMETERS4-55To create a new access control rule:1. Click Add PC on the Access Control screen. The Access Control Add PC screen will appear. 2. Define the appropriate rule settings for client PC services.3. Click OK and then click SAVE SETTINGS to save your settings.
CONFIGURING THE BARRICADE4-56MAC FilterThe MAC Filter allows you to define what client PC's can access the Internet. When filtering function is enabled only the MAC addresses defined in the MAC Filtering table will have access to the Internet. All other client devices will be denied access.You can enter up to 32 MAC addresses in this table. • MAC Address Control: select enable or disable.• MAC Filtering Table: enter the MAC address in the space provided.
CONFIGURATION PARAMETERS4-57URL BlockingThe Barricade allows the user to block access to web sites by entering either a full URL address or just a keyword. This feature can be used to protect children from accessing violent or pornographic web sites. You can define up to 30 sites here.
CONFIGURING THE BARRICADE4-58Schedule RuleYou may filter Internet access for local clients based on rules. Each access control rule may be activated at a scheduled time. Define the schedule on the Schedule Rule screen, and apply the rule on the Access Control screen.
CONFIGURATION PARAMETERS4-59Follow these steps to add a schedule rule:1. Click Add Schedule Rule on the Schedule Rule screen. The Edit Schedule Rule screen will appear.2. Define the appropriate settings for a schedule rule.3. Click OK and then click SAVE SETTINGS to save your settings.
CONFIGURING THE BARRICADE4-60Intrusion Detection• Intrusion Detection FeatureStateful 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. Scroll down to view more information.
CONFIGURATION PARAMETERS4-61
CONFIGURING THE BARRICADE4-62•Stateful Packet InspectionThis 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.•When hackers attempt to enter your network, we can alert you by e-mailEnter your email address. Specify your SMTP and POP3 servers, user name, and password.
CONFIGURATION PARAMETERS4-63•Connection PolicyEnter the appropriate values for TCP/UDP sessions as described in the following table. Parameter Defaults DescriptionFragmentationhalf-open wait10 sec Configures the number of seconds that a packet state structure remains active. When the timeout value expires, the router drops the unassembled packet, freeing that structure for use by another packet. TCP SYN wait30 sec Defines how long the software will wait for a TCP session to synchronize before dropping the session. TCP FIN wait5 sec Specifies how long a TCP session will be maintained after the firewall detects a FIN packet. TCP connection idle timeout3600 seconds (1 hour)The length of time for which a TCP session will be managed if there is no activity. UDP session idle timeout30 sec The length of time for which a UDP session will be managed if there is no activity.H.323 data channel idle timeout180 sec The length of time for which an H.323 session will be managed if there is no activity.
CONFIGURING THE BARRICADE4-64•DoS Criteria and Port Scan CriteriaSet up DoS and port scan criteria in the spaces provided (as shown below). Note: The firewall does not significantly affect system performance, so we advise enabling the prevention features to protect your network.Parameter Defaults DescriptionTotal incomplete TCP/UDP sessions HIGH300 sessionsDefines the rate of new unestablished sessions that will cause the software to start deleting half-open sessions.Total incomplete TCP/UDP sessions LOW250 sessions Defines the rate of new unestablished sessions that will cause the software to stop deleting half-open sessions.Incomplete TCP/UDP sessions (per min) HIGH250 sessions Maximum number of allowed incomplete TCP/UDP sessions per minute.Incomplete TCP/UDP sessions (per min) LOW200 sessions Minimum number of allowed incomplete TCP/UDP sessions per minute. Maximum incomplete TCP/UDP sessions number from same host10 Maximum number of incomplete TCP/UDP sessions from the same host. Incomplete TCP/UDP sessions detect sensitive time period300 msec Length of time before an incomplete TCP/UDP session is detected as incomplete.Maximum half-open fragmentation packet number from same host30 Maximum number of half-open fragmentation packets from the same host.Half-open fragmentation detect sensitive time period10000 msec Length of time before a half-open fragmentation session is detected as half-open.Flooding cracker block time300 second Length of time from detecting a flood attack to blocking the attack.
CONFIGURATION PARAMETERS4-65DMZIf you have a client PC that cannot run an Internet application properly from behind the firewall, you can open the client up to unrestricted two-way Internet access. Enter the IP address of a DMZ (Demilitarized Zone) host on this screen. Adding a client to the DMZ may expose your local network to a variety of security risks, so only use this option as a last resort.
CONFIGURING THE BARRICADE4-66SNMPUse the SNMP configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP).• Select the SNMP Operation mode from the drop down menu.
CONFIGURATION PARAMETERS4-67CommunityA computer attached to the network, called a Network Management Station (NMS), can be used to access this information. Access rights to the agent are controlled by community strings. To communicate with the Barricade, the NMS must first submit a valid community string for authentication. Note: Up to five community names may be entered.Parameter DescriptionCommunity A community name authorized for management access.Access Management access is restricted to Read Only (Read) or Read/Write (Write).Valid Enables/disables the entry.
CONFIGURING THE BARRICADE4-68TrapSpecify the IP address of the NMS to notify when a significant event is detected by the agent. When a trap condition occurs, the SNMP agent sends an SNMP trap message to any NMS specified as a trap receiver. Parameter DescriptionIP Address Traps are sent to this address when errors or specific events occur on the network.Community A community string (password) specified for trap management. Enter a word, something other than public or private, to prevent unauthorized individuals from accessing information on your system.Version Sets the trap status to disabled, or enabled with V1 or V2c.The v2c protocol was proposed in late 1995 and includes enhancements to v1 that are universally accepted. These include a get-bulk command to reduce network management traffic when retrieving a sequence of MIB variables, and a more elaborate set of error codes for improved reporting to a Network Management Station.
CONFIGURATION PARAMETERS4-69UPnPThe Universal Plug and Play architecture offers pervasive peer-to-peer network connectivity of PCs of all form factors, intelligent appliances, and wireless devices. UPnP enables seamless proximity network in addition to control and data transfer among networked devices in the office, home and everywhere within your network.UPnP allows the device to automatically:• join a network• obtain an IP address• convey its capabilities and learn about the presence and capabilities of other devices.Check Enable to activate this function.

CONFIGURING THE BARRICADE4-72Fast Path FEC Correction There are two latency paths that may be used: fast and interleaved. For either path, a forward error correction (FEC) scheme is employed to ensure higher data integrity. For maximum noise immunity, an interleaver may be used to supplement FEC.Interleaved Path FEC Correction An interleaver is basically a buffer used to introduce a delay, allowing for additional error correction techniques to handle noise. Interleaving slows the data flow and may not be optimal for real-time signals such as video transmission.Fast Path CRC Error The number of Fast Path Cyclic Redundancy Check errors.Interleaved Path CRC Error The number of Interleaved Path Cyclic Redundancy Check errors.Loss of Signal Defect Momentary signal discontinuities.Loss of Frame Defect Failures due to loss of frames.Loss of Power Defect Failures due to loss of power.Fast Path HEC Error Fast Path Header Error Concealment errors.

A-1APPENDIX ATROUBLESHOOTINGThis section describes common problems you may encounter and possible solutions to them. The Barricade can be easily monitored through panel indicators to identify problems. Troubleshooting ChartSymptom ActionLED IndicatorsPower 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.
TROUBLESHOOTINGA-2LED IndicatorsLink 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 ProblemsCannot ping the Barricade from the attached LAN• Verify that the IP addresses are properly configured. For most applications, you should use the Barricade’s 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.Troubleshooting ChartSymptom Action
TROUBLESHOOTINGA-3Management ProblemsCannot connect using the web browser• Be sure to have configured the Barricade with a valid IP address, subnet mask, and default gateway.• Check that you have a valid network connection to the Barricade and that the port you are using has not been disabled.• Check the network cabling between the management station and the Barricade.Forgot or lost the password• Press the Reset button on the rear panel (holding it down for at least 10 seconds) to restore the factory defaults.Troubleshooting ChartSymptom Action
B-1APPENDIX BCABLESEthernet CableCaution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.SpecificationsWiring ConventionsFor Ethernet connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
