Chapter 4
PC Configuration

This Chapter details the PC Configuration required on the local ("Internal") LAN.

Overview

For each PC, the following may need to be configured:

• TCP/IP network settings
• Internet Access configuration

Windows Clients

This section describes how to configure Windows clients for Internet access via the Broadband Router.

The first step is to check the PC's TCP/IP settings.

The Broadband Router uses the TCP/IP network protocol for all functions, so it is essential that the TCP/IP protocol be installed and configured on each PC.

TCP/IP Settings - Overview

If using the default Broadband Router settings, and the default Windows TCP/IP settings, no changes need to be made.

• By default, the Broadband Router will act as a DHCP Server, automatically providing a suitable IP Address (and related information) to each PC when the PC boots.
• For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP client.

If using a Fixed (specified) IP address, the following changes are required:

• The Gateway must be set to the IP address of the Broadband Router
• The DNS should be set to the address provided by your ISP.

Checking TCP/IP Settings - Windows 9x/ME:

1. Select Control Panel - Network. You should see a screen like the following:

   

   Figure 8: Network Configuration

2. Select the TCP/IP protocol for your network card.
3. Click on the Properties button. You should then see a screen like the following.

Ensure your TCP/IP settings are correct, as follows:

Using DHCP

To use DHCP, select the radio button Obtain an IP Address automatically. This is the default Windows setting. Using this is recommended. By default, the Broadband Router will act as a DHCP Server.

Restart your PC to ensure it obtains an IP Address from the Broadband Router.

Using "Specify an IP Address"

If your PC is already configured, check with your network administrator before making the following changes:

• On the Gateway tab, enter the Broadband Router's IP address in the New Gateway field and click Add, as shown below. Your LAN administrator can advise you of the IP Address they assigned to the Broadband Router.

• On the DNS Configuration tab, ensure Enable DNS is selected. If the DNS Server Search Order list is empty, enter the DNS address provided by your ISP in the fields beside the Add button, then click Add.

3. Select the network card for your LAN.
4. Select the appropriate radio button - Obtain an IP address from a DHCP Server or Specify an IP Address, as explained below.

Obtain an IP address from a DHCP Server

This is the default Windows setting. Using this is recommended. By default, the Broadband Router will act as a DHCP Server.

Restart your PC to ensure it obtains an IP Address from the Broadband Router.

Specify an IP Address

If your PC is already configured, check with your network administrator before making the following changes.

1. The Default Gateway must be set to the IP address of the Broadband Router. To set this:
   • Click the Advanced button on the screen above.
   • On the following screen, click the Add button in the Gateways panel, and enter the Broadband Router's IP address, as shown in Figure 14 below.
   • If necessary, use the Up button to make the Broadband Router the first entry in the Gateways list.

2. The DNS should be set to the address provided by your ISP, as follows:
   • Click the DNS tab.
   • On the DNS screen, shown below, click the Add button (under DNS Service Search Order), and enter the DNS provided by your ISP.

Checking TCP/IP Settings - Windows 2000:

1. Select Control Panel - Network and Dial-up Connection.
2. Right - click the Local Area Connection icon and select Properties. You should see a screen like the following:

   

   Figure 16: Network Configuration (Win 2000)

3. Select the TCP/IP protocol for your network card.
4. Click on the Properties button. You should then see a screen like the following.

5. Ensure your TCP/IP settings are correct, as described below.

Using DHCP

To use DHCP, select the radio button Obtain an IP Address automatically. This is the default Windows setting. Using this is recommended. By default, the Broadband Router will act as a DHCP Server.

Restart your PC to ensure it obtains an IP Address from the Broadband Router.

Using a fixed IP Address ("Use the following IP Address")

If your PC is already configured, check with your network administrator before making the following changes.

• Enter the Broadband Router's IP address in the Default gateway field and click OK. (Your LAN administrator can advise you of the IP Address they assigned to the Broadband Router.)
• If the DNS Server fields are empty, select Use the following DNS server addresses, and enter the DNS address or addresses provided by your ISP, then click OK.

Checking TCP/IP Settings - Windows XP

1. Select Control Panel - Network Connection.
2. Right click the Local Area Connection and choose Properties. You should see a screen like the following:

   

   Figure 18: Network Configuration (Windows XP)

3. Select the TCP/IP protocol for your network card.
4. Click on the Properties button. You should then see a screen like the following.

5. Ensure your TCP/IP settings are correct.

Using DHCP

To use DHCP, select the radio button Obtain an IP Address automatically. This is the default Windows setting. Using this is recommended. By default, the Broadband Router will act as a DHCP Server.

Restart your PC to ensure it obtains an IP Address from the Broadband Router.

Using a fixed IP Address ("Use the following IP Address")

If your PC is already configured, check with your network administrator before making the following changes.

4. Select "I connect through a local area network (LAN)" and click Next.
5. Ensure all of the boxes on the following Local area network Internet Configuration screen are unchecked.
6. Check the "No" option when prompted "Do you want to set up an Internet mail account now?".
7. Click Finish to close the Internet Connection Wizard.
   Setup is now completed.

For Windows XP

1. Select Start Menu - Control Panel - Network and Internet Connections.
2. Select Set up or change your Internet Connection.
3. Select the Connection tab, and click the Setup button.
4. Cancel the pop-up "Location Information" screen.

9. Click Finish to close the New Connection Wizard.
   Setup is now completed.

Accessing AOL

To access AOL (America On Line) through the Broadband Router, the AOL for Windows software must be configured to use TCP/IP network access, rather than a dial-up connection. The configuration process is as follows:

• Start the AOL for Windows communication software. Ensure that it is Version 2.5, 3.0 or later. This procedure will not work with earlier versions.
• Click the Setup button.
• Select Create Location, and change the location name from "New Locality" to "Broadband Router".
• Click Edit Location. Select TCP/IP for the Network field. (Leave the Phone Number blank.)
• Click Save, then OK.
  Configuration is now complete.
• Before clicking "Sign On", always ensure that you are using the "Broadband Router" location.

Macintosh Clients

From your Macintosh, you can access the Internet via the Broadband Router. The procedure is as follows.

1. Open the TCP/IP Control Panel.
2. Select Ethernet from the Connect via pop-up menu.
3. Select Using DHCP Server from the Configure pop-up menu. The DHCP Client ID field can be left blank.
4. Close the TCP/IP panel, saving your settings.

Note:

If using manually assigned IP addresses instead of DHCP, the required changes are:

• Set the Router Address field to the Broadband Router's IP Address.
• Ensure your DNS settings are correct.

Linux Clients

To access the Internet via the Broadband Router, it is only necessary to set the Broadband Router as the "Gateway".

Ensure you are logged in as "root" before attempting any changes.

Fixed IP Address

By default, most Unix installations use a fixed IP Address. If you wish to continue using a fixed IP Address, make the following changes to your configuration.

• Set your "Default Gateway" to the IP Address of the Broadband Router.
• Ensure your DNS (Name server) settings are correct.

To act as a DHCP Client (recommended)

The procedure below may vary according to your version of Linux and X -windows shell.

1. Start your X Windows client.
2. Select Control Panel - Network
3. Select the "Interface" entry for your Network card. Normally, this will be called "eth0".
4. Click the Edit button, set the "protocol" to "DHCP", and save this data.
5. To apply your changes
   • Use the "Deactivate" and "Activate" buttons, if available.
   • OR, restart your system.

Other Unix Systems

To access the Internet via the Broadband Router:

• Ensure the "Gateway" field for your network card is set to the IP Address of the Broadband Router.
• Ensure your DNS (Name Server) settings are correct.
