802.11g Router Applications ACCESSING THE INTERNET The most common use of the 802.11g Router is to provide shared Internet access to allow everyone on your LAN to surf the web and send/receive emails or files. The 802.11g Router can automatically acquire a public IP address when connecting to the Internet. In turn, it will automatically assign IP addresses to PCs (requesting DHCP client devices) on your LAN - you don’t have to apply for and assign IP addresses to PCs on your network.
802.11g Router User’s Guide A Security Overview More and more people are concerned about protecting your local network from the Internet. The 802.11g Router provides several ways to keep your network secure: Devices on your wired or wireless network are assigned private IP addresses; therefore remote users from the Internet cannot see nor access them. The 802.11g Router implements IP packet filtering capabilities, which you can use to selectively filter (discard) packets to/from the Internet.
Easy configuration and monitoring through the use of a Web-browser based GUI, a Command Line Interface (CLI) through a remote telnet session, or SNMP commands from a remote SNMP management station Setup Wizard for easy configuration/installation Setting Up the device The 802.11g Router can be managed by a local PC on either the wired or wireless LAN network. To do this, the 802.11g Router must have an IP address, which can be statically configured, or is dynamically obtained from a DHCP server on the LAN.

You can delete a mapping by selecting the corresponding entry and press the DELETE SELECTED button. DHCP Table: Press this button will cause the screen to jump to DHCP client table page.
802.11g Router User’s Guide Multiple DMZ The router supports one hardware DMZ port, multiple software DMZ ports, plus one default DMZ port. The hardware DMZ is implemented through the hardware: the router has a separate hardware Ethernet port, to which multiple devices with public IP addresses assigned by the ISP can be connected. Incoming data for these devices from the Internet will be sent by the router to the hardware Ethernet port directly. No configuration would be required.
Virtual Server Settings A Virtual Server is a server built on a single or a cluster of real servers. A DMZ server is a term commonly used to describe the default Virtual Server - the router will redirect all traffic from the Internet without a valid port address mapping to this device. An HTTP server with a private IP address on the LAN allows access from the Internet by mapping a special port to the HTTP server. In this case, the HTTP service will be mapped to a port of the Router.
802.11g Router User’s Guide Special Applications Special applications such as the Microsoft instant messaging or some Internet games are getting to be increasingly popular. These applications usually work in the following manner: A client can start an Internet game by first registering with a game server on the Internet. Other clients can, using the corresponding protocol, join the game by checking with the server and deciding if to join the game. A client can "leave" the game at any time.
Trigger Port: You need to specify, based on instructions provided by your application’s user manual, the (UDP/TCP) port number in the router that the initiating client uses to start an Internet game. Trigger Type: Select UDP, TCP, or both for the trigger port. Opened ports: You need to specify the port numbers in the router that joining clients can use to communicate with the initiating client, again based on instructions provided by your application user manual.
802.11g Router User’s Guide The 802.11g Router allows you to define a list of MAC addresses. One of three mutually exclusive rules can be selected to forward/filter data packets based on these MAC addresses. Disable MAC address control list: When this radio button is selected, no MAC address filtering will be performed. Enable GRANT address control list: When this radio button is selected, only packets received from the wireless LAN interface with the configured MAC addresses will be allowed/forwarded.
IP Filtering Settings Three mutually exclusive rules can be defined to forward/filter IP packets based on their IP address and/or port numbers. Disable IP filtering: If this is selected, the IP filtering feature is disabled. No IP filtering will be performed. GRANT IP access: When this is elected, packets received from/transmitted to WAN with specified (source or destination) IP addresses will be allowed/forwarded.
802.
IP Routing Settings Dynamic Routing: enable gateway to change the routing table dynamically through LAN port. Static Routing: If you have routers on your LAN or WAN, you can configure static routes on the 802.11g Router to route network traffic to a specific, predefined destination. The 802.11g Router can route packets based only on the packet's destination not on the source of a packet. Static routes must be defined if the LAN or WAN are segmented into subnets.
802.11g Router User’s Guide Wireless Settings You can use this screen to configure various parameters of your 802.11g Router. Beacon Interval: The 802.11g Router broadcasts beacon frames regularly to announce its existence. The beacon Interval specifies how often beacon frames are transmitted - in time unit of milliseconds. Its default value is 100; a valid value should be between 1 and 1000. RTS Threshold: RTS/CTS frames are used to gain control of the medium for transmission.
2432 bytes, with a default value of 2432. A value of zero activates the RTS/CTS handshake before every transmission. It is recommended that this value does not deviate from the default too much. Fragmentation: When the size of a unicast frame exceeds the fragmentation threshold, the frame will be fragmented before transmission. The threshold should have a value of 256-2346 bytes, with a default value of 2346.
802.11g Router User’s Guide MAC address filtering based authentication requires a MAC address filter table to be created in either the 802.11g Router and/or the RADIUS server. During the Authentication phase, the MAC address filter table is searched for a match against the wireless client’s MAC address to determine whether the station is to be allowed or denied to access the network. The RADIUS server can also be used for 802.1x EAP/MD5 authentication. IEEE 802.
Dynamic DNS Settings Some people advertise the IP addresses of their routers so that Internet users can access these routers (which is really to access virtual servers behind these routers) using these IP addresses. However, for those routers that are assigned dynamic IP addresses from the ISP, since IP addresses change, this approach requires additional work. The 802.
802.11g Router User’s Guide Username: the username required to log in to the domain name server maintained by DynDNS.org. Password: the password required to log in to the domain name server maintained by DynDNS.org.
