Appendix C
Preparing Your Network
This appendix describes how to prepare your network to connect to the Internet through the
FVL328 Prosafe High Speed VPN Firewall and how to verify the readiness of broadband Internet
service from an Internet service provider (ISP).
What You Will Need Before You Begin
You need to prepare these three things before you can connect your firewall to the Internet:
1.
A computer properly connected to the firewall as explained below.
2.
Active Internet service such as that provided by a DSL or Cable modem account.
3.
The Internet Service Provider (ISP) configuration information for your account.
LAN Hardware Requirements
The FVL328 Firewall connects to your LAN via twisted-pair Ethernet cables.
To use the FVL328 Firewall on your network, each computer must have an installed Ethernet
Network Interface Card (NIC) and an Ethernet cable. If the computer will connect to your network
at 100 Mbps, you must use a Category 5 (CAT5) cable such as the one provided with your firewall.
The broadband modem must provide a standard 10 Mbps 10BASE-T or 100 Mbps 100BASE-T
Ethernet interface.
Note:
If an ISP technician configured your computer during the installation of a
broadband modem, or if you configured it using instructions provided by your ISP, you
may need to copy the current configuration information for use in the configuration of
your firewall. Write down this information before reconfiguring your computers. Refer
to
“Worksheet for Recording Your Internet Connection Information“ on page C-3
” for
further information.

LAN Configuration Requirements
For the initial connection to the Internet and configuration of your firewall, you will need to
connect a computer to the firewall which is set to automatically get its TCP/IP configuration from
the firewall via DHCP. The computer you use must have a Web browser such as Internet Explorer
v5 or greater or Netscape Communicator v4.7 or greater.
Note:
Please refer to
“Preparing Your Computers for TCP/IP Networking“ on page C-4
for
assistance with DHCP configuration.
Internet Configuration Requirements
Depending on how your ISP or IT group set up your Internet access, you will need one or more of
these configuration parameters to connect your firewall to the Internet:
•
Host and Domain Names
•
ISP Login Name and Password
•
ISP Domain Name Server (DNS) Addresses
•
Fixed or Static IP Address
Where Do I Get the Internet Configuration Parameters?
There are several ways you can gather the required Internet connection information.
•
Your ISP should have provided you with all the information needed to connect to the Internet.
If you cannot locate this information, you can ask your ISP to provide it or you can try one of
the options below.
•
If you have a computer already connected using the active Internet access account, you can
gather the configuration information from that computer.
•
For Windows 95/98/Me, open the Network control panel, select the TCP/IP entry for the
Ethernet adapter, and click Properties.
•
For Windows 2000/XP, open the Local Area Network Connection, select the TCP/IP entry
for the Ethernet adapter, and click Properties.
•
For Macintosh computers, open the TCP/IP or Network control panel.
•
You may also refer to the FVL328
Resource CD
for the NETGEAR Router ISP Guide which
provides Internet connection information for many ISPs.
Once you locate your Internet configuration parameters, you may want to record them on the page
below according to the instructions in
“Worksheet for Recording Your Internet Connection
Information“ on page C-3
.

Worksheet for Recording Your Internet Connection Information
Print this page. Fill in the configuration parameters from your Internet Service Provider (ISP).
ISP Login Name:
The login name and password are case sensitive and must be entered exactly as
given by your ISP. Some ISPs use your full e-mail address as the login name. The Service Name is
not required by all ISPs. If you connect using a login name and password, then fill in the
following:
Login Name: ______________________________
Password: ____________________________
Service Name: _____________________________
Fixed or Static IP Address:
If you have a static IP address, record the following information. For
example,
169.254.141.148
could be a valid IP address.
Fixed or Static Internet IP Address: ______
.______
.______
.______
Subnet Mask: ______
.______
.______
.______
Gateway IP Address: ______
.______
.______
.______
ISP DNS Server Addresses:
If you were given DNS server addresses, fill in the following:
Primary DNS Server IP Address: ______
.______
______
.______
Secondary DNS Server IP Address: ______
.______
.______
.______
Host and Domain Names:
Some ISPs use a specific host or domain name like
CCA7324-A
or
home
. If you haven’t been given host or domain names, you can use the following examples as a
guide:
•
If your main e-mail account with your ISP is
, then use
aaa
as your host name.
Your ISP might call this your account, user, host, computer, or system name.
•
If your ISP’s mail server is
mail.xxx.yyy.com
, then use
xxx.yyy.com
as the domain name.
ISP Host Name: _________________________
ISP Domain Name: _______________________

Preparing Your Computers for TCP/IP Networking
Computers access the Internet using a protocol called TCP/IP
(Transmission Control Protocol/
Internet P
rotocol
). Each computer on your network must have TCP/IP installed and selected as its
networking protocol. If a Network Interface Card
(NIC) is already installed in your PC, then TCP/
IP is probably already installed as well.
Most operating systems include the software components you need for networking with TCP/IP:
•
Windows
®
95 or later includes the software components for establishing a TCP/IP network.
•
Windows 3.1 does not include a TCP/IP component. You need to purchase a third-party TCP/
IP application package such as NetManage Chameleon.
•
Macintosh Operating System 7 or later includes the software components for establishing a
TCP/IP network.
•
All versions of UNIX® or Linux® include TCP/IP components. Follow the instructions
provided with your operating system or networking software to install TCP/IP on your
computer.
In your IP network, each PC and the firewall must be assigned a unique IP addresses. Each PC
must also have certain other IP configuration information such as a subnet mask (netmask), a
domain name server (DNS) address, and a default gateway address. In most cases, you should
install TCP/IP so that the PC obtains its specific network configuration information automatically
from a DHCP server during bootup. For a detailed explanation of the meaning and purpose of
these configuration items, refer to “
Appendix B, “Networks, Routing, and Firewall Basics
.”
The FVL328 Firewall is shipped preconfigured as a DHCP server. The firewall assigns the
following TCP/IP configuration information automatically when the computers are rebooted:
•
PC or workstation IP addresses—192.168.0.2 through 192.168.0.254
•
Subnet mask—255.255.255.0
•
Gateway address (the firewall)—192.168.0.1
These addresses are part of the IETF-designated private address range for use in private networks.

Configuring Windows 95, 98, and Me for TCP/IP Networking
As part of the PC preparation process, you need to manually install and configure TCP/IP on each
networked PC. Before starting, locate your Windows CD; you may need to insert it during the
TCP/IP installation process.
Install or Verify Windows Networking Components
To install or verify the necessary components for IP networking:
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:
You must have an Ethernet adapter, the TCP/IP protocol, and Client for Microsoft Networks.
