Introduction 2-1

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:

Reference Manual for the Model FVS318 Broadband ProSafe VPN Firewall
2-2 Introduction
M-10146-01
• 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.

Reference Manual for the Model FVS318 Broadband ProSafe VPN Firewall
Introduction 2-3
M-10146-01
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
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.
