Introduction
This chapter describes the features of the NETGEAR FVL328 Prosafe High Speed VPN Firewall.
The FVL328 Firewall is now ICSA certified. It provides connection for multiple computers to the
Internet through an external broadband access device (such as a cable modem or DSL modem) and
supports IPSec-based secure tunnels to IPSec-compatible VPN servers.
About the FVL328
The FVL328 is a complete security solution that protects your network from attacks and intrusions
and enables secure communications using Virtual Private Networks (VPN). Unlike simple Internet
sharing routers that rely on Network Address Translation (NAT) for security, the FVL328 uses
Stateful Packet Inspection for Denial of Service (DoS) attack protection and intrusion detection.
The 8-port FVL328 provides highly reliable Internet access for up to 253 users with up to 100
concurrent VPN tunnels.
Summary of New Features in the FVL328
The NETGEAR FVL328 VPN ProSafe Firewall contains many new features, including:
•
ICSA Certified, Small/Medium Business (SMB) Category
•VPNC Certified
•Enhanced Logging
Key Features

Model FVL328 ProSafe High-Speed VPN Firewall Reference Manual
Virtual Private Networking
The FVL328 Firewall provides a secure encrypted connection between your local network and
remote networks or clients. Its VPN features include:
•Support for up to 100 simultaneous VPN connections.
•Support for industry standard VPN protocols.
The FVL328 Prosafe High Speed VPN Firewall supports standard keying methods (Manual or
IKE), standard authentication methods (MD5 and SHA-1), and standard encryption methods
(DES, 3DES). It is compatible with many other VPN products.
•Support for up to 168 bit encryption (3DES) for maximum security.
•Support for VPN Main Mode, Aggressive mode, or Manual Keying.
•Support for Fully Qualified Domain Name (FQDN) configuration when the Dynamic DNS
feature is enabled with one of the supported service providers.
•VPNC Certified
A Powerful, True Firewall
Unlike simple Internet sharing NAT routers, the FVL328 is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
•DoS protection
Automatically detects and thwarts 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 FVL328 will log security events such as blocked incoming traffic, port scans, attacks, and
administrator logins. You can configure the firewall to e-mail the log to you at specified
intervals. You can also configure the firewall to send immediate alert messages to your e-mail
address or e-mail pager whenever a significant event occurs.
•ICSA Certified, Small/Medium Business (SMB) Category version 4.0
2-2Introduction
M-10144-01
Model FVL328 ProSafe High-Speed VPN Firewall Reference Manual
ICSA Small/Medium Business Category
The NETGEAR FVL328 provides meets the ICSA SMB Category by providing Remote
Administration over an encrypted link from a public source. Additionally, the firewall provides a
default security policy denying all inbound non-Remote Administration related traffic originating
from public network sources while allowing a set of common services outbound.
The FVL328 enforces another security policy allowing a standard set of services inbound and
outbound. Therefore, a means to configure Access Control Rules will be available on the product
Content Filtering
With its content filtering feature, the FVL328 prevents objectionable content from reaching your
computers. 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 FVL328 can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. Both the local LAN and the Internet W AN
interfaces are 10/100 Mbps, autosensing, and capable of full-duplex or half-duplex operation.

Protocol Support
The FVL328 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. Supported protocols include:
Introduction2-3
M-10144-01
Model FVL328 ProSafe High-Speed VPN Firewall Reference Manual
•The Ability to Enable or Disable IP Address Sharing by NAT
The FVL328 allows several networked computers 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 NAT, allows the use of an inexpensive single-user
ISP account. This feature can also be turned off completely for using the FVL328 in settings
where you want to manage the IP address scheme of your organization.
•Automatic Configuration of Attached computers by DHCP
The FVL328 dynamically assigns network configuration information, including IP, gateway,
and domain name server (DNS) addresses, to attached computers using Dynamic Host
Configuration Protocol (DHCP). This feature greatly simplifies configuration of computers 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 computers. The firewall obtains actual DNS addresses
from the ISP during connection setup and forwards DNS requests from the LAN.
•PPP over Ethernet (PPPoE)
PPPoE 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 computer.
•Point-to-Point Tunneling Protocol PPTP login support for European ISPs and 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. See “Configuring
Dynamic DNS” on page 4-6.
Easy Installation and Management
You can install, configure, and operate the FVL328 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.
2-4Introduction
M-10144-01
Model FVL328 ProSafe High-Speed VPN Firewall Reference Manual
•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 using secure SLL protocol. 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 Intern et connectivity and reboot the firewall. You can
use these diagnostic functions directly from the FVL328 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 upgrades
