CONFIGURING THE BARRICADE4-28Access 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 Barricade.
WIRELESS4-29SecurityTo make your wireless network safe, you should turn on the security function. The Barricade supports the following security mechanism:•WEP•WPA
CONFIGURING THE BARRICADE4-30WEPIf you want to use WEP to protect your wireless network, you need to set the same parameters for the Barricade and all your wireless clients.To generate the key automatically with passphrase, enter a string of characters and click the GENERATE button. Select the default key from the drop-down menu. Click SAVE SETTINGS. Note: The passphrase can consist of up to 32 alphanumeric characters.To manually configure the encryption key, enter five hexadecimal pairs of digits for the 64-bit key, or enter 13 pairs for the 128-bit key. (A hexadecimal digit is a number or letter in the range 0-9 or A-F.)Note: WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet.Parameter DescriptionWEP Mode Select 64 bit or 128 bit key to use for encryption.Key Entry Method Select Hex or ASCII to use for encryption key.Static WEP Key SettingYou may automatically generate encryption keys or manually enter the keys.

CONFIGURING THE BARRICADE4-36Wi-Fi Protected Setup (WPS)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 an eight-digit PIN number and the Push Button Control (PBC).Check Enable and click SAVE SETTINGS.Pressing Generate New PIN creates a new Current PIN number.Pressing Restore Default PIN sets the PIN code to the factory default number. Take the following steps for easy network security settings.
WIRELESS4-37PIN Code Setup1. 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 user manual of the client device.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 configuration utility.4. Click the Start PIN button on the screen.
CONFIGURING THE BARRICADE4-38Push Button Configuration (PBC) MethodTo achieve successful WPS connection, you can use one of the following ways: (1) push and hold the WPS button on your Barricade, or (2) click the Start PBC button on this screen.1. Power on your network devices such as an access point and client network devices.2. Press the WPS button for 4 seconds, or click the Start PBC button on the screen.3. Press the WPS button or click the PBC button on your client devices of your network.Note: This connection procedure must be done within 2 minutes after pressing the WPS button on the Barricade.
WIRELESS4-39ManualFor client devices without WPS, manually configure the device as displayed on the screen.
CONFIGURING THE BARRICADE4-40NATNetwork Address Translation allows multiple users to access the Internet sharing one public IP.
NAT4-41Address 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 BARRICADE4-42Virtual ServerIf you configure the ADSL Router 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 ADSL Router 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.
NAT4-43Special 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.
CONFIGURING THE BARRICADE4-44NAT Mapping Table This screen displays the current NAPT (Network Address Port Translation) address mappings. NAT Mapping Table displays the current NAPT 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 mots updated values.The content of the NAT Mapping Table is described as follows.• Protocol - protocol of the flow. • Local IP - local (LAN) host’s IP address for the flow. • Local Port - local (LAN) host’s 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) host’s IP address for the flow. • Peer Port - remote (WAN) host’s port number for the flow.
ROUTING4-45RoutingThese 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 BARRICADE4-46Routing 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 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.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.
FIREWALL4-47FirewallThe 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“Intrusion Detection,” page 4-54.)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 BARRICADE4-48Access 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.The following items are on the Access Control screen: Parameter DescriptionEnable Filtering FunctionEnable or Disable Access control function. Normal Filtering Table Displays descriptive list of Filtering rules defined.
FIREWALL4-49To 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 settings for client PC services.3. Click OK and then click SAVE SETTINGS to save your settings.
CONFIGURING THE BARRICADE4-50MAC FilterThe MAC Filter allows you to define what client PC’s can access the Internet. When 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. 1. MAC Address Control: select enable or disable.2. MAC Filtering Table: enter the MAC address in the space provided.
FIREWALL4-51URL BlockingThe ADSL Router 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 BARRICADE4-52Schedule 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.
FIREWALL4-53Follow 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 BARRICADE4-54Intrusion 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.
FIREWALL4-55•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
CONFIGURING THE BARRICADE4-56sources 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.
FIREWALL4-57•Connection PolicyEnter the appropriate values for TCP/UDP sessions as described in the following table. Parameter Defaults DescriptionFragmentation half-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 wait 30 sec Defines how long the software will wait for a TCP session to synchronize before dropping the session. TCP FIN wait 5 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.
