NOTE: Dell technical support representatives do not support the configuration options in the Advanced Settings portion of the configuration program. These options are provided for your convenience only; however, the advanced settings are fully documented and explained in this guide.

NOTE: The options "Port Forwarding Settings" and "Static Routing" are invisible if you are in Access Point Mode.

NOTE: After making changes to any section in Advanced Settings and clicking the SUBMIT button, you are taken to a page where you can click the Save & Restart button. Click this button to store changes and to reboot the router. You must save all new settings for the changes to take effect.

Advanced IP Settings

The Dell TrueMobilie 2300 Wireless Broadband Router comes with an assigned IP address and IP subnet mask. These settings apply only to the Local Network portion of the router. If you are installing the unit on an existing network or simply want to change these values, make sure the IP subnet mask is the same for all devices on your network. The network portion of the IP address must also be the same for all devices on your network.

NOTE: Dell strongly suggests you do not change the IP address unless there is a specific reason for doing so.

While you are changing the IP address, be aware that:
 

• Changing the IP address of the Wireless Broadband Router also changes the IP address pool if the DHCP server is enabled.
• If you are using the Wireless Broadband Router with a cable modem or DSL line, you should assign a "private" IP address. Private IP addresses are in one of three ranges:
  • 10.0.0.1-10.254.254.254
  • 172.16.0.1-172.31.254.254
  • 192.168.0.1-192.168.254.254
• You must use the new IP address to access the web-based configuration tool.

NOTICE: You should only change the IP address or IP subnet mask if you are installing the Wireless Broadband Router on an existing wired network and the DHCP server function for your Wireless Broadband Router is disabled in the Advanced Settings. For more information, contact your network administrator.

DHCP Server Settings

Dynamic Host Configuration Protocol (DHCP), defines a way to automatically assign IP addresses to computers on a network. IP addresses are managed by a DHCP server. If a Windows computer is configured to obtain an IP address automatically, it automatically gets an address from the DHCP server.
 

Enable DHCP Server Functions

By default, the Wireless Broadband Router is set to function as a DHCP server. If you are installing the unit on an existing network that already has a DHCP server or simply do not want the Wireless Broadband Router to function as the network's DHCP server, uncheck the box Enable DHCP Server Functions to disable the DHCP server function.
 

IP  Address Pool Range

The IP Address Pool Range section provides a means of controlling a low and high value for the IP addresses on a network. Use the indicated fields to define the range of IP addresses you would like the Wireless Broadband Router to provide to DHCP clients.  The valid range of numbers you should enter is between 1 and 254.

The lease time is the amount of time a user will be allowed to use the IP address assigned by the DHCP server.  You may specify the lease time that DHCP server offers for the client to use the IP address.  This setting is especially useful in campus or other environments where users change frequently. 

IP Address Reservation

Specific IP addresses may also be reserved for particular devices in a network. The IP Address Reservation fields allows you to reserve up to four IP addresses for a specific system. The Computer MAC field is the MAC address of your network card on the client computer interfacing the same network as the router.  Use the input boxes under IP Address to indicate the IP address for those devices that should use a manually-defined IP address.

Time Zone

Use the Time Zone page to select your local time zone from the pull-down list. The Time Zone Settings affects the Intruder Detection Log. This setting offsets the time stamp on IP packets that are in Greenwich Mean Time (GMT). IP packets may not always have this stamp, or they may have an invalid stamp; thus, the time zone information is not always accurate.

The Time Zone Selection also affects the Parent Control option.  This option allows parents to control Internet access.  To enable this option, go to Advanced Settings -> Parental Control section of the router's web-configuration tool. By default, there is no blocking at any time on Internet access.

Advanced Wireless

Enable Wireless

Check this box to enable radio transmission and reception on the Wireless Broadband Router.
Uncheck the box to disable the radio.

Hide my wireless network

Checking this box disables the Wireless Broadband Router to send out beacon packets to the wireless network.  It is unchecked by default and other users can easily find and make association to your Wireless Broadband Router with the use of a site survey tool.
If you want to increase wireless network security, you can enable this feature.

Mode

TrueMobile 2300 Router is 802.11g-compatible. You can select "both b & g" (dual mode), or "802.11b", or "802.11g"  from the Mode list.

SSID

Service Set Identifier (SSID) is a 32-character name that uniquely identifies all the computers and equipment that make up the wireless network.

Transfer Rate

Transfer rate can be set to automatic, or some other fixed value.  It's recommended that you set the transfer rate to automatic (Auto)  to allow the wireless network devices to transmit at a rate they deem optimum at any given point of time.

Channel

The channel settings let you set the channel for this Wireless Broadband Router. The radio channel is the place over which a communication transmission occurs. The operating channel number depends on the regulatory domain.
 

NOTE: If you want to configure the settings of Beacon Interval, RTS Threshold, Fragmentation Threshold, and DTIM Interval, please ensure that the Advanced Options is checked first.

Beacon Interval

The amount of time in Kusecs (one Kusec equals 1,024 microseconds) between radio beacons from the Wireless Broadband Router to its client stations.  The value range is from 1 to 65535.

RTS Threshold

The packet size above which the Wireless Broadband Router will issue a Request to Send before sending the packet. 

RTS (Request to Send) mechanism prevents the "Hidden Node" problem. When two stations are within range of the same Access Point (AP) but are not within range of each other, they are hidden nodes for each other. The packets from these two stations may collide if they arrive at the AP at the same time. To prevent data collision with the hidden node, you can activate RTS mechanism. If RTS mechanism is activated, the station will send a RTS first to inform the AP that it is going to transmit the data. Then, the AP will reply with the CTS (Clear to Send) to all stations within its range to notify all other stations and reserve the bandwidth for your data.

The RTS threshold controls what size data packet would issue a RTS. Only when the packet exceeds the RTS threshold, the device will send a RTS before sending the packet. There is trade-off to consider what value you should set for the RTS threshold. Small value causes RTS to be sent more often, and it would waste the bandwidth. However, the more often RTS packets are sent, the sooner the system can recover from collisions. It is recommended to use the default value or only minor reductions of this default value. The value range is from 0 to 2347.
 

Fragmentation Threshold

The fragmentation threshold, specified in bytes, determines whether data packets will be fragmented and at what size. Packets that are smaller than the specified fragmentation threshold value will not be fragmented. Packets that are larger than the fragmentation threshold will be fragmented into smaller packets and transmitted a piece at a time instead of all at once. Thus, it will reduce the need for retransmission and improve overall network performance. Fragmentation is activated usually when the system is in heavy traffic and interference environment. The setting must be within the range of 256 to 2346 bytes. It is recommended to use the default value or only minor reductions of this default value.

DTIM Interval

DTIM (Delivery Traffic Indication Message) Interval, always a multiple of the beacon period, determines how often the beacon contains a traffic indicator map (TIM). The TIM alerts stations in sleep state to stay awake long enough to receive their data frames.  The value range is from 1 to 255.

Wireless Bridge

Wireless Bridging can be used to increase the coverage of your wireless network and/or to provide wired access to a remote computer(s). You need two or more Dell TrueMobile 2300 Wireless Broadband Routers to setup Wireless Bridging.

To setup wireless bridging, configure the wireless settings for all of your Dell TrueMobile 2300 Wireless Broadband Routers to the same settings.
 

Configuring your router for Wireless Bridging:

1. Open your web browser and go to http://my.router (or the default address http://192.168.2.1).
    
2. Click the Advanced Settings tab on the top navigation bar.
    
3. Click the Advanced wireless button on the left navigation bar.
    
4. Ensure Enable Wireless is checked.
    
5. Type your wireless network name in the Network name (SSID) field if you desire to change it from default settings “Wireless”.
    
6. Ensure Advanced Options is unchecked.
    
7. Enable Wireless Bridge.
    
8. Enter the Wireless MAC address(es) of the other Dell TrueMobile 2300 Wireless Broadband Router(s) that you want to bridge.




NOTE: To connect two bridges together, enter the MAC address of the bridge at the other end.  To connect three bridges together, enter the MAC addresses of the other two bridges in the bridge acted as the multipoint center.  The other two bridges only need to be entered the MAC address of the center bridge.



9. Click the Submit button.
    
10. Click the Save & Restart button.
     
11. When your web browser returns to the main page of the Wireless Broadband Router, the device has successfully restarted with the new settings.
     
12. Repeat steps 1 to 11 for each Dell TrueMobile 2300 Wireless Broadband router you want to bridge.
     

    NOTE: Ensure all Dell TrueMobile 2300 wireless Broadband Routers set to same wireless settings and all router(s) not directly connected to Internet should be configured to Access point mode.

Port Forwarding Settings

DMZ

DMZ (demilitarized zone) feature allows access to all ports. (For example, if you have problems hosting a game server, you can choose this option. This will open all ports to your game server.)
 

1. Check the Enable DMZ Host box.
    
2. Type the IP address of the computer that you want to run the gaming application in the DMZ IP Address field.
    
3. Click SUBMIT button to activate the setting.

NOTE: Configuring the Wireless Broadband Router in DMZ mode is useful if you want to play certain games through the Wireless Broadband Router, but the ports cannot be opened with all other existing configuration tools.

NOTICE: Opening a service to the Internet causes security concerns. Pay careful attention to security alerts, and make sure that strong access controls and authentication are in place before allowing access to any services.

Custom Port Forwarding Settings

Port Forwarding may be more difficult than DMZ to configure.  However, it provides a relatively safe way of running a Internet application or providing a Internet service from behind a firewall since only a single port (or a range of ports) is exposed to the Internet.  You can configure this port forwarding setting to create a custom rule that defines a specific port and protocol for data traffic to pass through to the specific computer on your LAN.

An example is a HTTP server running on your LAN, which you want it to be available to the Internet.  Your public IP address (that your ISP gives you) is X.X.X.X (The X is a number), and you have a computer hosting the HTTP server at LAN address 192.168.2.2 on your  Wireless Broadband Router (192.168.2.1) controlled LAN.  You can configure 192.168.2.2 to have port forwarding for port 80 (HTTP), then users on the Internet can go to http://X.X.X.X and get the HTTP server (192.168.2.2).  The data traffic entering service port 80 will be directed to the computer (192.168.2.2), and other computers on your LAN will not see this data traffic.

For some internet applications (such as Internet messaging and gaming applications), you can configure this port forwarding setting so that these applications can function correctly behind the firewall.  These applications are required to have specific TCP/UDP ports.   The ports for these applications and the protocol type will depend on what Internet services you are using.  Please check with your service provider or application's user manual to have the information first.

Make sure you have the following ports setup as described below.

1. Check the Enable box.
    
2. Enter the desired name or description in the Service Name field.
    
3. In the Incoming Ports field, enter a range of ports.  If you want to specify only a single port number, enter the same number in both boxes.
    
4. In the Destination IP Address field, enter the IP address of the computer you want to receive the connection request.
    
5. In the Destination MAC Address field, enter the MAC address of the computer you want to receive the connection request.
    

   Information: Find the MAC address The steps below show how to find the MAC address of the computer in Windows 2000 and XP. Click on Start -> Run. Type cmd in the Open field and then press Enter or click OK button. In the command prompt, type ipconfig/all to obtain the Physical Address (=MAC address). Write down this Physical Address (=MAC address).  You need this information for setting. Its format should be XX-XX-XX-XX-XX-XX.  The X is a hexadecimal digit (0-9 or A-F).

   
   
6. In the Destination Port field, enter a port number or a range of ports of the machine to which you are mapping.
    
7. In the Port type field, select TCP, UDP, or both protocols.  The protocol could be specified in your application's documentation.
    
8. Click SUBMIT button to activate the setting.
    

For example, if you want to play game "Fighter Ace II" on a computer with an IP address of 192.168.2.3, enter 3 for the Destination IP Address.  Find the MAC address of this computer and enter it for the Destination MAC Address.  Select TCP as the Port type.  Enter "50000" and "51000" for two boxes of Incoming Ports and also for the Destination Port.  Click SUBMIT button to activate the setting.  For other games or services, please consult the application's user manual.

Commonly Used Ports

Services	Protocol Type	Ports
HTTP (WEB Server)	TCP	80
FTP	TCP	20, 21
TELNET	TCP	23
SMTP (Mail Server)	TCP	25
POP3 (Mail Server)	TCP	110
IRC	TCP	6667
NNTP (News Server)	TCP	119

Port Triggering

Port triggering allows the router to watch outgoing data for specific port number.  The IP address of the the computer that sends the data is remembered by the router,  so that when the requested data returns through the router, the data will be passed to the specific computer by way of IP address and port mapping rules.  The router opens the port when the Port Triggering happens.  When the computer running the application stops sending the data through this port, the router will close the port.

1. Check the Enable box.
    
2. Enter the desired name or description in the Application Name field.
    
3. In the Trigger Port field, enter a port number.  Check with your Internet application provider for more information on what the Trigger Port it is using.
    
4. Select TCP (Transmission Control Protocol), or UDP (User Datagram Protocol), or both protocols as the Trigger Port Type.
    
5. Specify the range of the Public Ports by entering the start and end port numbers in the required fields.
    
6. Select TCP (Transmission Control Protocol), or UDP (User Datagram Protocol), or both (TCP and UDP) as the Public Port Type.
    
7. Click SUBMIT button to activate the setting.

Static Routing

Static routes are manually configured routes to remote networks. That is, the route is predefined and is not discovered by the Routing Information Protocol (RIP), as in dynamic routing. Static routing allows you to assign a gateway to an IP address or network. If there are routers on your internal network that do not function with RIP 1 or 2, you can set up a static route to those routers.

The advantage to using static routing is that network traffic is reduced; thus, static routing is beneficial for slow Internet connections. Routing using static routes is practical for small networks. For larger networks, the router needs to dynamically keep track of changes in the physical wiring of the network, and the use of dynamic routing (RIP) is recommended. 
 

NOTICE: The Static Routing settings are intended for advanced network administrators only.  Do not change these settings unless you are certain of the correct values. You may not be able to access the configuration tool if invalid information is entered.

To use static routing, manually add the Destination IP Address, Subnet Mask, and Gateway IP Address for each route you are adding to the Static Routing Table, and click ADD. If you are routing to an entire network, the last number in the destination IP address should be a zero (0); for example, 192.168.0.0.

NOTE: In static routing, the Wireless Broadband Router does NOT dynamically discover routing information and does NOT use RIP. The Wireless Broadband Router currently does NOT support RIP.

Use the checkboxes beside each route and the DELETE button to remove static routes from the Static Routing Table.

Administration Settings

Password Settings

The Wireless Broadband Router uses a password to authenticate the user before allowing changes to be made to any network settings.  If you would like to change the current password, check the Change Your Password checkbox and enter the new password in both New Password and Retype Password fields. Write down the password and keep it in a secure location for future reference.

System Administration

• HTTP Port No.

Do not change the HTTP Port value unless you have reason to do so. Typically, web servers listen for incoming web requests on port 80.

• Allow remote user to configure the device

If you would like a remote user to be able to administer your Wireless Broadband Router over the Internet, check the box titled Allow remote user to configure the device. Enter the IP address for the remote administration host computer.

• Allow remote user to ping the device

Check the box Allow remote user to ping the device to enable your Wireless Broadband Router to be "ping"ed by any user on the Internet. This feature is helpful if you want to let other Internet users to check the status of your Wireless Broadband Router.

• Enable UPnP function

UPnP stands for Universal Plug and Play, a protocol which allows UPnP-enabled client computers such as Windows XP to discover and configure the Wireless Broadband Router.  One of most common use of UPnP on the router is to open ports to allow application-specific data to be forwarded through the router for various Internet services or gaming applications.  The router detection and the router configuration process can be carried out automatically by the UPnP-enabled client applications such as MSN Messenger so you won't have to do it manually.  Check the Enable UPnP function box to enable this service or clear the box to disable it.

If you have an Windows XP system, you can use it to access and control the router while the router's UPnP function is enabled.  Here are some examples of what you can do with UPnP from your XP system.

Example 1 )  Access the router's Web Configuration tool without knowing its  IP address.

1. Double click on the "My Network Neighborhood" icon from  the desktop.
   
2. Double click on the "Broadband Router" icon that is created for your router.
   
   
   
3. This will bring up the authentication screen of the router's Web configuration tool.  Enter the correct password and click OK to access the Web configuration tool.
   
   
   

Example 2 )  Manage the router's port forwarding rules from the XP interface.

NOTE: You have already configured a port forwarding rule for the service via the web configuration tool, you don't need to perform the following steps for the same service again.

1. Right click on the "My Network Neighborhood" icon from the desktop.
   
2. Right click the Internet Connection icon created for the router. (See below)
   
   
   
   
3. Right click the icon and select Property.
   
4. Click Settings.
   
5. Click Add.
   
6. Enter Description of service, IP address of the service host, External Port number for this service, Internal Port number for this service and select either TCP or UDP.
   
   
   For example, the graph below shows an example of how to enable a computer with an IP address 192.168.2.101 to host a public HTTP server.
