If no traffic is passing through during the span of time your specified, the PPP session is terminated. DNS A Domain Name system (DNS) server is like an index of IP addresses and Web addresses. If you type a Web address into you browser, a DNS server will find that name in its index and find the matching IP address. 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 addresses are also provided dynamically. However, if there is a DNS server that you would rather use, you need to specify the IP address below. Domain Name Server (DNS) Address: Type in the DNS address that you get from your service provider. Secondary DNS Address (optional): provider. Type in the secondary DNS address that you get from your service Bridge The router acts like a 5-port switch on this mode for transmitting the packets between LAN and WAN interface.

Local Domain Name: You can check the Report this host as the DNS server box to use this host as the default DNS. Or you can uncheck the box and manually set up the DNS IP address in the Primary/Secondary DNS IP address fields. The DNS server addresses will be passed to the DHCP clients along with the IP addresses. The DHCP clients use the DNS to map a domain name to its corresponding IP address and vice versa. DHCP Client List DHCP Clent List shows the IP address, host name and MAC address of the clients which connected to the Barricade. 38 Chapter 5: Web Configuration WLAN Wireless LAN Settings This page shows you how to configure the wireless LAN setting. WLAN is short for Wireless Local Area Network. To get the wireless broadband router quick working for your wireless LAN, basically, you must have your wireless SSID and your preferred channel set up. If the network security is your great concern, you can enable the WEP Encryption functionality and type in your encryption key for set-ups in appropriate fields. Wireless SSID (Service Set Identity): A name that uniquely identifies a wireless domain. All wireless clients that want to communicate with the ADSL Router must have the same SSID as it. Desired Channel: The frequency in which the radio links are about to be established. Select channel that you 39 Wireless Broadband Router User’s Manual want. Usually the wireless clients will scan the whole operable channels and then select the desired communications channel automatically. WEP Encryption Key Mode: Select ASCII or Hex as the calculation standard. If using HEX format, the utility converts two entered characters into its corresponding ASCII code and vice versa. Note that when using HEX format, only digits 0-9 and letters A-F are allowed. Valid key length for each encryption type is as below: 64 Bit HEX Format 10 hexadecimal digits ASCII Format 5 ASCII characters 128 Bit 26 hexadecimal digits 13 ASCII characters Authetication Algorithm: Choose Open Key or Shared Key as the Authentication Type. Default TX Key: Select one WEP key from the four keys to encrypt the data you transmit. Wired Equivalent Privacy Mechanism The privacy security function can enhance wireless media security by encryption technology. All wireless clients must set the same encryption key to maintain the tightened communication with the ADSL Router properly. The Authenticate Algorithm options are: When the wired Equivalent Privacy Mechanism is Turns off. Using Open-key as authentication algorithm, you are running the risk of allowing some unauthorized wireless LAN cards that have the capability of eavesdropping your SSID to associate itself to the device. Turns on encryption. Wired Equivalent Privacy Mechanism is Turns on. You should select the encryption key length as 64- or 128-bit key. Then enter the encryption key in Key Entry fields. Note: When Wired Equivalent Privacy Mechanism is enabled, the wireless client must be configured with exactly the same encryption level (64 or 128-bit) and encryption key as identified in the Router, so that access to the unit is allowed. WLAN MAC Control To block certain wireless client PC accessing your wireless network based on the MAC address, you can use WLAN MAC Control page to do it. 40 Policy: “Allow” means to allow the MAC address for the wireless device listed below to be connected to your router (AP). “Deny” means the MAC address for the wireless device listed below cannot be connected to your router (AP). MAC Address: Type in the MAC Address. Chapter 5: Web Configuration Add and Delete: Click Add to add a new MAC address on the list. Click Delete to remove the MAC address that you do want to. NAT NAT allows multiple users at your local site to access the Internet through a single public IP address or multiple public IP addresses. NAT can also prevent hacker attacks by mapping local addresses to public addresses for key services such as the Web or FTP. Virtual Server This page shows all virtual server rules configured in your ADSL Router. The Router implements NAT to let your entire local network appear as a single machine to the Internet. The typical situation is that you have local servers for different services and you want to make them publicly accessible. With NAT applied, it will translate the internal IP addresses of these servers to a single IP address that is unique on the Internet. NAT function not only eliminates the need for multiple public IP addresses but also provides a measure of security for your LAN. When the router receives an incoming IP packet requesting for access to your local server, the router will recognize the service type according to the port number in this packet (e.g., port 80 indicates HTTP service and port 21 indicates FTP service). By specifying the port number, you tell the router which service should be forwarded to the local IP address you specify. After you setting the virtual server you should modify the filter rule whichever port and service you set on virtual server. Because the firewall has protect the route by filter rule so that you should update the filter rule after you set up virtual server. 41 Wireless Broadband Router User’s Manual Server IP: Specify the server IP address. Mapping Ports: Enter the mapping port for the IP address. 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 router redirects the external service request to the appropriate server (located at another internal IP address). NAT Link Table The table list below shows the status for current internet connection links information. 42 Chapter 5: Web Configuration Firewall This page is used to set the firewall for your system. Please choose one from the provided items and click Apply to enable it. MAC Control You can block certain client PCs accessing the Internet based on MAC addresses. MAC Address Control: Enable the MAC address control by checking the box. Allow unspecified MAC address connect to Internet: Make unspecified MAC address to connect to the Internet with any difficulty, please check this box. DMZ(Demilitarized Zone) A DMZ (De-Militarized Zone) separates an external network from directly referencing an internal network. With DMZ configuration, a DMZ host acts as a neutral zone between the private network and the outside network. For example, if you have a host providing online games or videoconferencing applications which are incompatible through NAT, you can specify its IP address here and then click Apply button. Enable: Enable the DMZ function. IP Address of Virtual DMZ Host: Type in the last IP address. 43 Wireless Broadband Router User’s Manual Routing For multiple routers that installed on your network, please configure each unit's routing functions for proper using. Static Routing This setting allows different IP domain users to access the Internet through this device. This page shows all the routing rules of data packets going through your Wireless Broadband Router if it runs in routing mode. Under normal circumstances, the router has adequate routing information after it has been configured for Internet access, and you don’t need to configure additional static routes. Unless your network is unusual case such as multiple routers or multiple IP subnets and you must configure static routes. For example, if the circumstances below apply to your network: You have another subnet network in your network. Your another network is 10.1.1.x. Then you need to create a static route. You should enter the destination IP address 10.3.1.x and gateway IP address 192.168.1.1 to commit the setting. At the first time you have to configure your router, you will find a default route created with your service provider as the gateway, and the second static route was created to your local network for all 192.168.1.1 addresses. Destination LAN IP: Type in the destination LAN IP address. Subnet Mask: Type in the subnet mask of the destination IP address that your service provider gives you. Gateway: Type in the gateway address. Dynamic Routing Routing Information Protocol (RIP) is utilized as a means of exchanging routing information between routers. It helps the routers to determine optimal routes. This page allows you to enable/disable this function. 44 Chapter 5: Web Configuration Dynamic Routing: Make the router automatically adjusts to physical changes in the network's layout. The settings include RIP1,RIP Compatible and RIP2. By default, RIP is disabled with Disable selected. To disable RIP, just select Disable from the drop-down list. Routing Table This page shows a table about routing information, such as Destination LAN IP, Subnet Mask, Gateway, Metric, Interface and so on. Destination LAN IP: It shows the destination address of the network where data packets are to be sent. Subnet mask: The subnet mask of the destination address. Gateway: It shows the IP address of Gateway. Metric: The number of the routers which connect to the destination. Interface: The interface that access point use for routing. Refresh: Click this button to refresh the routing information. 45 Chapter 6: Troubleshooting Chapter 6: Troubleshooting If the suggested solutions in this section do not resolve your problem, contact your system administrator or Internet service provider. Problems with LAN PCs on the LAN can not get IP addresses from the Wireless Broadband Router. The chances are that the interface used as DHCP server is modified and the client PCs do not renew IP addresses. If your DHCP server is enabled on Private IP Address previously and you modify the interface to Public IP Address, the client PCs should renew IP addresses. The PC on the LAN cannot access the Web page of the Wireless Broadband Router. Check that your PC is on the same subnet with the Wireless Broadband Router. The virtual server can’t be access after setting virtual server. Check the filter rule of the port that virtual server service setting for example, the virtual server service set FTP 21 you need update the filter rule of the ftp 21 Direction setting: Choose filter the packets that incoming action (In Bound) are Allow on the interface. Can’t access the Router’s Web Configuration interface from a PC on your local network. Make sure you are using the correct login information, the default password is admin (small letters). Make sure your PC’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your PC’s address should be in the range of 192.168.1.2 to 192.168.1.254. Note: 1. 2. 3. If you use DHCP server and your PC’s IP address is shown as 169.254.x.x: please renew the IP address and check the connection from the PC to the router. If you are using a wireless LAN card equipped PC, check that the SSID and WEP settings are the same for the router and PC. If your router’s IP address has been changed and you don’t know the current IP address, clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.1.1. Problems with WAN If you router can’t access the Internet. You should first determine whether the router is able to obtain a WAN IP address from the ISP. Or you have been assigned a static IP address. Check the IP address for the WAN port. If your ISP requires a login program as PPP over Ethernet (PPPoE), ensure the user name and password you enter are correctable. If your Broadband Wireless Router is set to routing mode and you use private IP addresses on the LAN, make sure Network Address Translation (NAT) is enabled. Your PC may not recognize any DNS server address. Check your DNS setting on the Broadband Wireless Router. 46 Chapter 7: Troubleshooting Check the physical connection between the Wireless Broadband Router and the LAN. At the DOS prompt, ping the IP address of the Wireless Broadband Router, e.g, ping 192.168.1.1. If the following response occurs: Relay from 192.168.1.1 bytes=32 time=100ms TTL=253 Then the connection between the Wireless Broadband Router and the network is OK. If you get a failed ping with the response of: Request time out Then the connection is fail. Check the cable between the Wireless Broadband Router and the network. Check the DNS setting of the Wireless Broadband Router. At the DOS prompt, ping the IP address of the DNS provided by your ISP. For example, if your DNS IP is 168.95.1.1, then ping 168.95.1.1. If the following response occurs: Relay from 168.65.1.1 bytes=32 time=100ms TTL=253 Then the connection to the DNS is OK. If you get a failed ping with the response of: Request time out Then the DNS is not reachable. Check your DNS setting on the Wireless Broadband Router. Problems with Upgrading The following lists the error messages that you may see during upgrading and the action to take. Error Message: Upload Data Error！Please make sure your file is correct! Possible cause: The firmware file format is invalid. Action: Check the file format is correct, otherwise download a firmware file with correct format. Error: The router shut down for some unknown reason and the web page got problem Possible cause: The firmware might be damaged. Action: Execute recovery firmware update. Simply type 192.168.0.1 on URL line to open the page. Choose the proper file and click Apply to execute the recovery process. When the file is copied, a successful web page appears as follows. Now the router’s firmware is upgraded. It 47 Wireless Broadband Router User’s Manual can be used again. 48 Chapter 7: Glossary Chapter 7: Glossary Authentication and WEP Encryption The absence of a physical connection between nodes makes the wireless links vulnerable to eavesdropping and information theft. To provide a certain level of security , the IEEE 802.11 standard has defined two types of authentication methods, open system and shared key. With open system authentication a wireless PC can join any network and receive any messages that are not encrypted. With shared key authentication, only those PCs that possess the correct authentication key can join the network. By default IEEE 802.11 wireless devices operate in an Open system network. DHCP (Dynamic Host Configuration Protocol) When operates as a DHCP server, the Wireless Broadband Router assign IP addresses to the client PCs on the LAN. The client PCs “leases” these Private IP addresses for a user-defined amount of time. After the lease time expires, the private IP address is made available for assigning to other network devices. The DHCP IP address can be a single, fixed public IP address, an your service provider assigned public IP address, or a private IP address. If you enable DHCP server on a private IP address, a public IP address will have to be assigned to the NAT IP address, and NAT has to be enabled so that the DHCP IP address can be translated into a public IP address. By this, the client PCs are able to access the Internet. Infrastructure mode A backbone to extend the service provided by network. This mode provides wireless connectivity to multiple wireless network devices within a fixed range or area of coverage, interacting with wireless nodes via an antenna. LAN (Local Area Network) & WAN (Wide Area Network) A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. A WAN, on the other hand, is an outside connection to another network or the Internet. The Ethernet side of the Wireless Broadband Router is called the LAN port. It is a twisted-pair Ethernet 10Base-T interface. A hub can be connected to the LAN port. More than one computers, such as server or printer, can be connected through this hub to the Wireless Broadband Router and composes a LAN. The WAN port of the Wireless Broadband Router composes the WAN interface, which supports PPP or RFC 1483 connecting to another remote DSL device or cable modem. MAC Address Media Access Code Address. A unique, 48-bit number assigned to every network interface card by the manufacturer. NAT (Network Address Translation) IP Address NAT is an Internet standard that translates a private IP within one network to a public IP address, either a static or dynamic one. NAT provides a type of firewall by hiding internal IP addresses. It also enables a company to use more internal IP addresses. If the IP addresses given by your your service provider are not enough for each PC on the LAN and the Wireless Broadband Router, you need to use NAT. With NAT, you make up a private IP network for the LAN and assign an IP address from that network to each PC. One of some public addresses is configured and mapped to a private workstation address when accesses are made through the gateway to a public network. For example, the Wireless Broadband Router is assigned with the public IP address of 168.111.1.1. With NAT enabled, it creates a Virtual LAN. Each PC on the Virtual LAN is assigned 49 Wireless Broadband Router User’s Manual with a private IP address with default value of 192.168.1.2 to 192.168.1.254. These PCs are not accessible by the outside word but they can communicate with the outside world through the public IP 168.111.1.1. Private IP Address Private IP addresses are also LAN IP addresses, but are considered “illegal” IP addresses to the Internet. They are private to an enterprise while still permitting full network layer connectivity between all hosts inside an enterprise as well as all public hosts of different enterprises. The Wireless Broadband Router uses private IP addresses by assigning them to the LAN that cannot be directly accessed by the Internet or remote server. To access the Internet, private network should have an agent to translate the private IP address to public IP address. RIP (Routing Information Protocol) RIP is a routing protocol that uses the distance-vector routing algorithms to calculate leasthops routes to a destination. It is used on the Internet and is common in the NetWare environment. It exchanges routing information with other routers. It includes V1, V2 and V1&V2, which controls the sending and receiving of RIP packets over Ethernet. SSID SSID is a thirty-two character(maximum) alphanumeric key identifying the wireless local area network. Service Set Identity. A group name shared by all members of an IEEE 802.11b network. Only devices with the same SSID are allowed to establish connections. For the wireless devices in a network to communicate with each other, all device must be configured with the same SSID. UDP (User Data gram Protocol) UDP is a connectionless transport service that does not own the reliability services provided by TCP. UDP gives applications a direct interface with IP and the ability to address a particular application process running on a host via a port number without setting up a connection session. Virtual Server You can designate virtual servers, e.g., a FTP, web, telnet or mail server, on your local network and make them accessible to the outside world. A virtual server means that it is not a dedicated server -- that is, the entire computer is not dedicated to running on the public network but in the private network. 50 Appendix: Specifications Appendix: Specifications Software Standards Compliance IEEE 802.11 / 802.11b Standard IEEE 802.3 / IEEE 802.3u Standard IEEE 802.1d MAC Bridges Standard Wireless LAN Features Fully compliant with IEEE 802.11 / IEEE 802.11b DSSS devices Provide 11 / 5.5 / 2 / 1 Mbps wireless connectivity to the wireless clients Auto fallback data rate under noisy environment IEEE 802.11 Wireless Access Point function Distributed Coordination Function (DCF) CSMA/CA Backoff Procedure NAV Management ACK Procedure Retransmission of unacknowledged frames RTS/CTS Handshake Duplicate Detection and Recovery Beacon Generation Probe Response Fragmentation and Reassembly Wired Equivalent Privacy Algorithm Authentication Algorithm Power Management Short Preamble and Long Preamble Association / Re-association / De-association Home Gateway Controller Features 1K MAC look-up table MAC security Auto-sense 10Base-T / 100Base-TX operation modes Wire speed reception and transmission for Ethernet Port Upper Layer Applications DHCP Server DHCP Client HTTP Server PPP over Ethernet NAT (IP Sharing) DNS Proxy 51 Wireless Broadband Router User’s Manual Virtual Server RIP v1&v2 Operation Modes 802.11/802.11b Access Point Roaming Seamless roaming within the same IP subnet Access Point Bridging Features Support self-learning transparent bridge specified in IEEE 802.1d between wired LAN and Wireless LAN Support up to 256 wireless MAC learning addresses Automatic Learning Process Forwarding Process Aging Function Filtering Database Security Features Support ESSID network identification for security Support 64-bit and 128-bit WEP Data Encryption and Decryption Support Authentication: Open System, Shared Key Access Control by MAC Address Configuration and Management Web-based browser configuration management.
