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.

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.
