Chapter 2
Introduction
This chapter describes the features of the NETGEAR FVS318 Broadband ProSafe VPN Firewall .
About the FVS318
The FVS318 is a complete security solution that protects your network from attacks and
intrusions. Unlike simple Internet sharing routers that rely on Network Address Translation (NAT)
for security, the FVS318 uses Stateful Packet Inspection for Denial of Service (DoS) attack
protection and intrusion detection. The 8-port FVS318 provides highly reliable Internet access for
up to 253 users.
Key Features
The FVS318 offers the following features.
• Trustworthy VPN Communications Over the Internet
• A Powerful, True Firewall
• Content Filtering
• Auto Uplink Ethernet Connection
• Extensive Protocol Support
• Easy Installation and Management
• Helpful Status Indicators
A description of these key features follows.
Virtual Private Networking (VPN)
The FVS318 VPN Firewall provides a secure encrypted connection between your local area
network (LAN) and remote networks or clients. It includes the following VPN features:
Introduction 2-1
M-10146-01
Reference Manual for the Model FVS318 Broadband ProSafe VPN Firewall
• Supports 8 VPN connections.
• Supports industry standard VPN protocols
The FVS318 VPN Firewall supports standard Manual or IKE keying methods, standard MD5
and SHA-1 authentication methods, and standard DES, 3DES, and AES encryption methods.
It is compatible with many other VPN products.
• Supports up to 256 bit AES encryption for maximum security.
A Powerful, True Firewall
Unlike simple Internet sharing NAT routers, the FVS318 is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• Denial of Service (DoS) protection
Automatically detects and thwarts Denial of Service (DoS) attacks such as Ping of Death,
SYN Flood, LAND Attack and IP Spoofing.
• Blocks unwanted traffic from the Internet to your LAN.
• Blocks access from your LAN to Internet locations or services that you specify as off-limits.
• Logs security incidents
The FVS318 will log security events such as blocked incoming traffic, port scans, attacks, and
administrator logins. You can configure the firewall to email the log to you at specified
intervals. You can also configure the firewall to send immediate alert messages to your email
address or email pager whenever a significant event occurs.
Content Filtering
With its content filtering feature, the FVS318 prevents objectionable content from reaching your
PCs. The firewall allows you to control access to Internet content by screening for keywords
within Web addresses. You can configure the firewall to log and report attempts to access
objectionable Internet sites.
Configurable Auto Uplink™ Ethernet Connection
With its internal 8-port 10/100 switch, the FVS318 can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. The 10/100 Mbps LAN and WAN
interfaces are autosensing and capable of full-duplex or half-duplex operation.
2-2 Introduction
M-10146-01
Reference Manual for the Model FVS318 Broadband ProSafe VPN Firewall
The firewall incorporates Auto UplinkTM technology. Each LOCAL Ethernet port will
automatically sense whether the Ethernet cable plugged into the port should have a ‘normal’
connection such as to a PC or an ‘uplink’ connection such as to a switch or hub. That port will then
configure itself to the correct configuration. This feature also eliminates the need to worry about
crossover cables, as Auto Uplink will accommodate either type of cable to make the right
connection.
Protocol Support
The FVS318 supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP). Appendix B, “Networks, Routing, and Firewall Basics” provides
further information on TCP/IP.
• IP Address Sharing by NAT
The FVS318 allows several networked PCs to share an Internet account using only a single IP
address, which may be statically or dynamically assigned by your Internet service provider
(ISP). This technique, known as Network Address Translation (NAT), allows the use of an
inexpensive single-user ISP account.
• Automatic Configuration of Attached PCs by DHCP
The FVS318 dynamically assigns network configuration information, including IP, gateway,
and domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic
Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on
your local network.
• DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the firewall provides its own
address as a DNS server to the attached PCs. The firewall obtains actual DNS addresses from
the ISP during connection setup and forwards DNS requests from the LAN.
• PPP over Ethernet (PPPoE)
PPP over Ethernet is a protocol for connecting remote hosts to the Internet over a DSL
connection by simulating a dial-up connection. This feature eliminates the need to run a login
program such as EnterNet or WinPOET on your PC.
• PPTP login support for European ISPs, BigPond login for Telstra cable in Australia.
• Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not permanently assigned. The firewall contains a client that can connect to
many popular Dynamic DNS services to register your dynamic IP address.

M-10146-01
Reference Manual for the Model FVS318 Broadband ProSafe VPN Firewall
Easy Installation and Management
You can install, configure, and operate the FVS318 within minutes after connecting it to the
network. The following features simplify installation and management tasks:
• Browser-based management
Browser-based configuration allows you to easily configure your firewall from almost any
type of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup
Wizard is provided and online help documentation is built into the browser-based Web
Management Interface.
• Smart Wizard
The firewall automatically senses the type of Internet connection, asking you only for the
information required for your type of ISP account.
• Remote management
The firewall allows you to login to the Web Management Interface from a remote location via
the Internet. For security, you can limit remote management access to a specified remote IP
address or range of addresses, and you can choose a nonstandard port number.
• Diagnostic functions
The firewall incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote
reboot. These functions allow you to test Internet connectivity and reboot the firewall. You can
use these diagnostic functions directly from the FVS318 when your are connected on the LAN
or when you are connected over the Internet via the remote management function.
• Visual monitoring
The firewall’s front panel LEDs provide an easy way to monitor its status and activity.
• Flash EPROM for firmware upgrade
• Regional support, including ISPs like Telstra DSL and BigPond or Deutsche Telekom.

Connecting the Firewall to the Internet
This chapter describes how to set up the firewall on your Local Area Network (LAN), connect to
the Internet, perform basic configuration of your FVS318 Broadband ProSafe VPN Firewall using
the Setup Wizard, or how to manually configure your Internet connection.
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 DSL or Cable modem
account.
LAN Hardware Requirements
The FVS318 VPN Firewall connects to your LAN via twisted-pair Ethernet cables.
Computer Requirements
To use the FVS318 VPN 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.
Cable or DSL Modem Requirement
The cable modem or DSL modem must provide a standard 10 Mbps 10BASE-T or 100 Mbps
100BASE-T Ethernet interface.

Reference Manual for the Model FVS318 Broadband ProSafe VPN Firewall
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.
Note: Please refer to Appendix C, "Preparing Your Network" for assistance with DHCP
configuration.
Internet Configuration Requirements
Depending on how your ISP set up your Internet account, 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 FVS318 Resource CD (SW-10021-01) 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 3-3.

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
aaa@yyy.com, 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.

How to Connect the FVS318 VPN Firewall
This section provides instructions for connecting the FVS318 Broadband ProSafe VPN Firewall
to your Local Area Network (LAN).
Note: The Resource CD included with your firewall contains an animated Installation Assistant to
help you through this procedure.
There are three steps to connecting your firewall:
1. Connect the firewall to your network
2. Log in to the firewall
3. Connect to the Internet
Follow the steps below to connect your firewall to your network. You can also refer to the
Resource CD included with your firewall which contains an animated Installation Assistant to help
you through this procedure.
1. Connect the Firewall to Your LAN
a. Turn off your computer and Cable or DSL Modem.
b. Disconnect the Ethernet cable (A) from your computer which connects to your Cable or
DSL modem.

Note: The FVS318 VPN Firewall incorporates Auto UplinkTM technology. Each LAN
Ethernet port will automatically sense whether the cable plugged into the port should have a
'normal' connection (e.g. connecting to a PC) or an 'uplink' connection (e.g. connecting to a
switch or hub). That port will then configure itself to the correct configuration. This feature
also eliminates the need to worry about crossover cables, as Auto Uplink will accommodate
either type of cable to make the right connection.
