Preparing Your Network

3-9

For a single-user Internet account, your ISP supplies TCP/IP configuration information for one

PC. With a typical account, much of the configuration information is dynamically assigned when

your PC is first booted up while connected to the ISP, and you will not need to know that dynamic

information.

In order to share the Internet connection among several computers, your firewall takes the place of

the single PC, and you need to configure it with the TCP/IP information that the single PC would

normally use. When the firewall’s Internet port is connected to the broadband modem, the firewall

appears to be a single PC to the ISP. The firewall then allows the PCs on the local network to

masquerade as the single PC to access the Internet through the broadband modem. The method

used by the firewall to accomplish this is called Network Address Translation (NAT) or IP

masquerading.

Login Protocols

Some ISPs require a special login protocol, in which you must enter a login name and password in

order to access the Internet. If you normally log in to your Internet account by running a program

such as WinPOET or EnterNet, then your account uses PPP over Ethernet (PPPoE).

When you configure your firewall, you will need to enter your login name and password in the

firewall’s configuration menus. After your network and firewall are configured, the firewall will

perform the login task when needed, and you will no longer need to run the login program from

your PC. It is not necessary to uninstall the login program.

Account Information

Unless these items are dynamically assigned by the ISP, your ISP should give you the following

basic information for your account:

•

An IP address and subnet mask

•

A gateway IP address, which is the address of the ISP’s router

•

One or more domain name server (DNS) IP addresses

•

Host name and domain suffix

For example, your account’s full server names may look like this:

mail.xxx.yyy.com

In this example, the domain suffix is

xxx.yyy.com

.

Preparing Your Network

If any of these items are dynamically supplied by the ISP, your firewall automatically acquires

them. If an ISP technician configured your PC during the installation of the broadband modem, or

if you configured it using instructions provided by your ISP, you need to copy configuration

information from your PC’s Network TCP/IP Properties window (or Macintosh TCP/IP Control

Panel) before reconfiguring your PC for use with the firewall. These procedures are described

next.

Obtaining ISP Configuration Information (Windows)

As mentioned above, you may need to collect configuration information from your PC so that you

can use this information when you configure the NETGEAR ProSafe Firewall. Following this

procedure is only necessary when your ISP does not dynamically supply the account information.

To get the information you need to configure the firewall for Internet access:

1.

On the Windows taskbar, click the Start button, point to Settings, and then click Control Panel.

2.

Double-click the Network icon.

The Network window opens, which displays a list of installed components.

3.

Select TCP/IP, and then click Properties.

The TCP/IP Properties dialog box opens.

4.

Select the IP Address tab.

If an IP address and subnet mask are shown, write down the information. If an address is

present, your account uses a fixed (static) IP address. If no address is present, your account

uses a dynamically-assigned IP address. Click “Obtain an IP address automatically”.

5.

Select the Gateway tab.

If an IP address appears under Installed Gateways, write down the address. This is the ISP’s

gateway address. Select the address and then click Remove to remove the gateway address.

6.

Select the DNS Configuration tab.

If any DNS server addresses are shown, write down the addresses. If any information appears

in the Host or Domain information box, write it down. Click Disable DNS.

7.

Click OK to save your changes and close the TCP/IP Properties dialog box.

You are returned to the Network window.

8.

Click OK.

9.

Reboot your PC at the prompt. You may also be prompted to insert your Windows CD.

Obtaining ISP Configuration Information (Macintosh)

As mentioned above, you may need to collect configuration information from your Macintosh so

that you can use this information when you configure the NETGEAR ProSafe Firewall. Following

this procedure is only necessary when your ISP does not dynamically supply the account

information.

To get the information you need to configure the firewall for Internet access:

1.

From the Apple menu, select Control Panels, then TCP/IP.

The TCP/IP Control Panel opens, which displays a list of configuration settings. If the

“Configure” setting is “Using DHCP Server”, your account uses a dynamically-assigned IP

address. In this case, close the Control Panel and skip the rest of this section.

2.

If an IP address and subnet mask are shown, write down the information.

3.

If an IP address appears under Router address, write down the address. This is the ISP’s

gateway address.

4.

If any Name Server addresses are shown, write down the addresses. These are your ISP’s DNS

addresses.

5.

If any information appears in the Search domains information box, write it down.

6.

Change the “Configure” setting to “Using DHCP Server”.

7.

Close the TCP/IP Control Panel.

Restarting the Network

Once you’ve set up your computers to work with the firewall, you must reset the network for the

devices to be able to communicate correctly.

1.

Turn off the DSL or cable modem, wait 15 seconds, and then turn it on again

2.

Turn off the firewall, and then turn it on again and wait until the Test light turns off.

3.

Restart any computer that is connected to the firewall.

Note:

If the modem doesn’t have an on/off switch, either pull the modem’s power adapter out of

the wall socket or power down the power strip.

Preparing Your Network

Ready for Configuration

After configuring all of your PCs for TCP/IP networking and connecting them to the local network

of your NETGEAR ProSafe Firewall, you are ready to access and configure the firewall. Proceed

to the next chapter.

Basic Configuration

4-1

Chapter 4

Basic Configuration

This chapter describes how to perform the basic configuration of your FR114P, FR114W or

FM114P Cable/DSL ProSafe Firewall using the Setup Wizard, which walks you through the

configuration process for your Internet connection.

Accessing the Web Configuration Manager

In order to use the browser-based Web Configuration Manager, your PC must have a web browser

program installed such as Microsoft Internet Explorer or Netscape Navigator. Because the

Configuration Manager uses Java, your Web browser must be Java-enabled and support HTTP

uploads. NETGEAR recommends using Microsoft Internet Explorer 5.0 or Netscape Navigator

4.7 or above. Free browser programs are readily available for Windows, Macintosh, or UNIX/

Linux.

To configure for Internet access using your browser:

1.

Connect your PC and firewall as described in the previous chapter.

Make sure your PC has been rebooted since connecting with the firewall.

2.

Launch your web browser.

Note:

If you normally use a login program (such as Enternet or WinPOET) to access the

Internet, do not launch that program.

3.

Click your browser’s Stop button.

4.

In the Address (or Location) box of your browser, type

and press ENTER.
