Configuring the 4-Port Broadband Router
The Web-based configuration utility can be used to change the settings of the 4-Port Broadband Router. A brief description of these settings is provided below.
Start up and Log in
Open an Internet browser and enter the 4-Port Broadband Router's IP address.
The following is the
After the connection is established, you will see the Web User Interface
for the Configuration
Note: After making any changes to the configuration options or security settings of the 4-Port Broadband Router, you must click Save in order for your changes to be saved and implemented.
This menu is used to view the current status information of the 4-Port Broadband Router. Within the Item column, you can view the pertinent information for your Wide Area Network (WAN) connection.
This information could be slightly different depending on the WAN type you choose.
The following is the information you can view if you have PPP over Ethernet, PPTP, or Dial-up Network selected as your WAN type:
This information could be slightly different depending on the WAN type you choose.
In this option you can change the administrator password. There is no
default password for the 4-Port Broadband Router. It is recommended that
you create a password after you successfully log in. If you choose not
to set a password at this time, you can set one or change your current
one at any time by clicking Toolbox on the side menu. The password
restricts who can access the configuration options of this utility.
Note: If at any time you forget your password, unplug the power supply. Press in and hold the RESET button. While holding the RESET button, plug in the power supply. When the 4-Port Broadband Router has power again, continue to hold the RESET button until the SYSTEM LED begins flashing. This will reset the 4-Port Broadband Router to the factory default settings.
The Clone MAC button is useful when your ISP binds (or locks) your connection to a specific MAC address. Cloning the MAC address allows you to reassign the MAC address without registering it with your ISP. Some ISPs require that you register the MAC address.
The View Log button will allow you to see the action history log for the 4-Port Broadband Router.
Click Reboot to reboot the 4-Port Broadband Router.
If you click Backup Setting, the settings of the 4-Port Broadband Router will be saved to a file.
You can click Reset to Default and then restart your 4-Port Broadband Router to restore the default settings of the 4-Port Broadband Router.
You can also obtain information about the firmware version and the WAN's
MAC Address in this area. Go to www.usr.com/support
to look for any firmware upgrades for your 4-Port Broadband Router. If
a new firmware upgrade exists for the 4-Port Broadband Router and you
have downloaded it, click Firmware Upgrade to apply the new firmware
version to your device.
This option displays the connection method of the WAN port. When you are using a dial-up connection, the username and password dialog boxes will be shown here.
Note: If you are required to enter any connection information, refer to the Before You Begin sections in the Introduction chapter of this guide for detailed instructions on obtaining this information. If you have any questions about your Internet connection or any of this information, contact your ISP.
A more detailed description of each WAN type option follows.
Static IP Address
The DHCP server of the 4-Port Broadband Router is set to Enable by default. The settings of the TCP/IP environment include IP address, Subnet Mask, Gateway, and DNS configurations. If the DHCP server of the 4-Port Broadband Router is enabled and you configure your computers to obtain an IP address automatically, your computer will automatically load the proper TCP/IP information provided by the 4-Port Broadband Router. The settings of DHCP server include the following items:
DHCP Server: You are given two options: Disable and Enable.
The Clients List... button will display a list of the computers that have requested an IP address from the 4-Port Broadband Router. This list will also record the MAC address of the clients that have requested an IP address.
The Fixed Mapping... button will launch the MAC Address Control screen. This allows you to control the mapping of the MAC addresses and IP addresses. You can also control which MAC address is allowed to connect to this device. Within this screen, you can enable or disable MAC Address Control, select or deselect Connection Control, and use a client's MAC address to assign an IP address. Each configuration has an ID number associated with it. This function can be used for a maximum of 32 clients, so the ID range is from 1 to 32.
The 4-Port Broadband Router's NAT (Network Address Translation) firewall filters out unrecognised packets to protect your home network. All hosts behind this firewall are invisible externally. Enabling the Virtual Server Mapping will make some of the host's ports accessible. The Virtual Server function is also known as port forwarding.
The Virtual Server function is made up of two components: an IP address and a service port. All requests to this port will be redirected to the computer that is specified by the Server IP.
Port forwarding sets up public services on your network. When Internet users make requests to a specific port in your network, the 4-Port Broadband Router will forward those requests to the appropriate computer. The computer must be configured to a static IP address to use port forwarding. Port forwarding is generally used to set up a Web server, ftp server, or e-mail server on your network. Some well-known services are included in a pre-defined list.
To add a server using Forwarding, perform the following steps:
For example, if you have an FTP server (port 21) at 192.168.123.1, a Web server (port 80) at 192.168.123.2, and a PPTP VPN server at 192.168.123.6, you need to specify the following virtual server mapping table:
Some applications require open service ports, such as Internet games, video conferencing, Internet telephony, and others. These applications cannot work with a pure NAT 4-Port Broadband Router since all the ports are blocked by default. This is a result of the 4-Port Broadband Router's NAT firewall function. Special Applications will allow some of these applications to work with a NAT 4-Port Broadband Router. If the Special Applications still do not allow an application to function correctly, refer to the DMZ host option in the "Miscellaneous Items" section of this Guide.
Trigger: This is the outbound port number that the application
This product provides some predefined settings in the drop-down menu on the bottom of the Web Page Interface. Select from the Popular applications drop-down menu, select an ID, and click Copy to copy a predefined setting.
Note: Only one computer can use a specific port number at a time.
Access Control allows you to assign the access rights for each user. First, you must divide users into different groups, as identified by their IP addresses. You can assign the members of Group 1, 2, and 3. The others are all members of the Default Group. Second, you must assign the access rights of each group. The access rights can either allow or block users to access specified TCP and UDP ports. For example:
Group Members Access Right Comments:
The MAC Level... button will launch the MAC Address Control screen. This allows you to control the mapping of the MAC addresses and IP addresses. You can also control which MAC address is allowed to connect to this device. Within this screen, you can enable or disable MAC Address Control, select Connection Control or Association Control, and assign the MAC address of a specific DHCP client to a particular ID number. The ID range is from 1 to 32.
SNMP stands for Simple Network Management Protocol. This will allow you to view and manage your network statistics. Within this section you can enable SNMP by selecting Local, Remote, or both. If neither is selected, SNMP will be disabled. There is a field for Get Community and for Set Community. Get Community is set to public by default and Set Community is set to private by default. If you wish to change either of these settings, you must enter the values.
IP Address of DMZ Host: The DMZ (Demilitarised Zone) Host is a computer that has all external Internet traffic forwarded to it. This allows a computer to be exposed to unrestricted two-way communication. This feature should be used only when necessary, since it removes the security of the NAT firewall.
Remote Administrator Host: In general, only intranet users can
browse the built-in Web pages to perform administration tasks. This feature
enables you to perform administrative tasks from a remote host. When this
feature is enabled, only the specified IP address can perform remote administration.
If the specified IP address is 0.0.0.0, any host can connect to the 4-Port
Broadband Router to perform administration tasks. When this feature is
enabled, the Web port will be shifted to 8080.
Administrator Time-out: This allows you to set a time period of inactivity before an administrator will be automatically logged out.
Discard PING from the WAN side: When enabled, this will cause the 4-Port Broadband Router to automatically drop any ping requests from outside the LAN without replying.
Non-standard FTP port: This must be configured if you want to acess an FTP server whose port number is not 21. If you reboot your 4-Port Broadband Router, you will lose this setting.
MAC Address for Wake-on-LAN: Wake-on-LAN is a technology that enables you to power up a networked device remotely. In order to use this feature, the target device must be Wake-on-LAN enabled and you have to know the MAC address of this device. Click Wake up and the 4-Port Broadband Router will send a wake-up frame to the target device.
The Logout option is a secure means of logging out of the Configuration Utility.
