Router IP

This presents both the Router’s IP Address and Subnet Mask as seen by your network.

Network Address Server Settings (DHCP)

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The

Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Router’s DHCP server option, you must configure all of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on your network.

DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you don’t want a DHCP server, then click the Disable radio button (no other DHCP features will be available).

Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the

Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253. The default Starting IP Address is 192.168.1.100.

Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign

IP addresses to. This number cannot be greater than 253. The default is 50.

Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased” this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address.

The default is 0 minutes, which means one day.

Static DNS (1-3). The Domain Name System (DNS) is how the Internet translates domain or website names into

Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. If you wish to use another, type that IP Address in one of these fields. You can type up to three DNS Server IP Addresses here. The

Router will use these for quicker access to functioning DNS servers.

WINS. The Windows Internet Naming Service (WINS) converts NetBIOS names to IP addresses. If you use a WINS server, enter that server’s IP Address here. Otherwise, leave this blank.

Time Setting

Change the time zone in which your network functions from this pull-down menu. (You can even automatically adjust for daylight savings time.)

The Setup Tab - Advanced Routing

This tab is used to set up the Router’s advanced functions. NAT allows mulitple uses to share one Internet connection. Dynamic Routing will automatically adjust how packets travel on your network. Static Routing sets up a fixed route to another network destination.

NAT. If this Router is hosting your network’s connection to the Internet, select Enable. If another Router exists on your network, select Disable. When Router is chosen, Dynamic Routing will be enabled.

Dynamic Routing. This feature enables the Router to automatically adjust to physical changes in the network’s layout and exchange routing tables with the other router(s). The Router determines the network packets’ route based on the fewest number of hops between the source and the destination. This feature is Disabled by default.

From the drop-down menu, you can also select LAN & Wireless, which performs dynamic routing over your

Ethernet and wireless networks. You can also select Internet, which performs dynamic routing with data coming from the Internet. Finally, selecting Both enables dynamic routing for both networks, as well as data from the

Internet.

Static Routing. To set up a static route between the Router and another network, select a number from the Static

Routing drop-down list. (A static route is a pre-determined pathway that network information must travel to reach a specific host or network.) Enter the information described below to set up a new static route. (Click the Delete This

Entry button to delete a static route.)

Enter Route Name. Enter a name for the Route here, using a maximum of 25 alphanumeric characters.

Destination LAN IP. The Destination LAN IP is the address of the remote network or host to which you want to assign a static route.

Subnet Mask. The Subnet Mask determines which portion of a Destination LAN IP address is the network portion, and which portion is the host portion.

Default Gateway. This is the IP address of the gateway device that allows for contact between the Router and the remote network or host.

Interface. This interface tells you whether the Destination IP Address is on the LAN & Wireless (Ethernet and wireless networks), the WAN (Internet), or Loopback (a dummy network in which one PC acts like a network— necessary for certain software programs).

The Wireless Tab - Basic Wireless Settings

The basic settings for wireless networking are set on this screen.

Wireless Network Mode. From this drop-down menu, you can select the wireless standards running on your network. If you have both 802.11g and 802.11b devices in your network, keep the default setting, Mixed. If you have only 802.11g devices, select G-Only. If you have only 802.11b devices, select B-Only. If you do not have any

802.11g and 802.11b devices in your network, select Disable.

Wireless Network Name (SSID). The SSID is the network name shared among all points in a wireless network.

The SSID must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 characters (use any of the characters on the keyboard). Make sure this setting is the same for all points in your wireless network. For added security, you should change the default SSID (linksys) to a unique name.

Wireless Channel. Select the appropriate channel from the list provided to correspond with your network settings. All devices in your wireless network must be broadcast on the same channel in order to function correctly.

Wireless SSID Broadcast. When wireless clients survey the local area for wireless networks to associate with, they will detect the SSID broadcast by the Router. To broadcast the Router's SSID, keep the default setting,

Enable. If you do not want to broadcast the Router's SSID, then select Disable.

The Wireless Tab - Wireless Security

The Wireless Security settings configure the security of your wireless network. There are three wireless security mode options supported by the Router: WPA Pre-Shared Key, WPA RADIUS, and WEP. (WPA stands for Wi-Fi

Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent

Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These three are briefly discussed here. For detailed instructions on configuring wireless security for the Router, turn to “Appendix B: Wireless

Security.”

WPA Pre-Shared Key. WPA gives you one encryption method, TKIP, with dynamic encryption keys. Select the type of algorithm, TKIP. Enter a WPA Shared Key of 8-32 characters. Then enter a Group Key Renewal period, which instructs the Router how often it should change the encryption keys.

WPA RADIUS. This option features WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use, TKIP.

Enter the RADIUS server’s IP Address and port number, along with a key shared between the Router and the server. Last, enter a Key Renewal Timeout, which instructs the Router how often it should change the encryption keys.

IMPORTANT: If you are using WPA, always remember that each device in your wireless network

MUST use the same WPA method and shared key, or else the network will not function properly.

The Wireless Tab - Advanced Wireless Settings

This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by an expert administrator as incorrect settings can reduce wireless performance.

Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the

Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so they know which rates will be used. The Router will also advertise that it will automatically select the best rate for transmission. The default setting is Default, when the Router can transmit at all standard wireless rates

(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless technology, and All, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of data transmission. If you want to specify the Router’s rate of data transmission, configure the Transmission Rate setting.

Control Tx Rate. The rate of data transmission should be set depending on the speed of your wireless network.

You can select from a range of transmission speeds, or you can select Auto to have the Router automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Router and a wireless client. The default value is Auto.

Preamble Type. The preamble defines the length of the CRC block for communication between the Router and the roaming Network Card. (High network traffic areas should use the shorter preamble type.) Select the appropriate preamble type, Long Preamble(default) or Short Preamble.

Authentication Type. The default is set to Auto, which allows either Open System or Shared Key authentication to be used. With Open System authentication, the sender and the recipient do NOT use a WEP key for authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication.

Beacon Interval. The default value is 100. Enter a value between 1 and 65,535 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless network.

DTIM Interval. This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message

(DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1.

Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation

Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.



Figure 6-23: Wireless Tab - Advanced Wireless Settings

25


RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2432, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2432.





26


The Security Tab - Filter

Filters block specific internal users from accessing the Internet. From the Filters tab, you can set up a filter through an IP address or a network port number.

Filter IP Address Range. To set up a filter using IP addresses, enter the range of IP addresses you wish to filter in the IP address fields. Users who have filtered IP addresses will not be able to access the Internet at all. If you only want to filter one IP address instead of a range of IP addresses, enter the same value into both fields. For instance, if you wish to filter the PC with the IP address of 192.168.1.5, enter 5 into both fields on one line:

192.168.1.5 ~ 192.168.1.5.

Filter Port Range. To filter users by network port number, select a protocol, then enter a network port number or a range of network ports. Enter the port numbers you want to filter in the port numbers fields. Users connected to the Router will no longer be able to access any port number listed there.

Filter MAC Address. This feature filters the Ethernet adapter’s specific MAC address from going out to the

Internet. To check your Ethernet adapter’s MAC address, you can run winipcfg or ipconfig in the command prompt, depending on which Windows operating system you are using. To set the MAC filter, click the Edit MAC

Filter Setting button. When the screen appears, select the range in the drop-down menu, and in a MAC number field, enter the 12-digit MAC address you want to filter. Click Apply to save the changes, or Undo to undo the changes. For information on obtaining a MAC address, go to Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter.

Block WAN Requests. Enable the Block WAN Request feature by checking the radio button beside Block

Anonymous Internet Requests and you can prevent your network from being pinged or detected by other

Internet users. Click Disabled it you want to allow anonymous Internet requests.The Block WAN Request feature also reinforces your network security by hiding your network ports. Both functions of the Block WAN Request feature make it more difficult for outside users to work their way into your network. This feature is enabled by default.

Filter Multicast. This feature allows for multiple transmissions to specific recipients at the same time. Select

Enabled to support the feature, or Disabled to keep the Router from multicasting.

Filter Internet NAT Redirection. This feature uses Port Forwarding to prevent access to local servers from your local networked computers.
