Chapter 2
Introduction
This chapter describes the features of the NETGEAR FVL328 Prosafe High Speed VPN Firewall.
The FVL328 Firewall is now ICSA certified. It provides connections 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:
•
Multi-DMZ (One-to-One DMZ)
–
Up to 7 different WAN IPs can be mapped, one-to-one, to up to 7 private LAN IPs.
•
Resettable WAN traffic meter
–
Programmable traffic limit
–
Can block traffic or send e-mail when limit reached
•
VPN Wizard that simplifies VPN setup and uses the VPNC defaults
•
Four groups for keyword blocking
•
E-mail authentication

Key Features
The FVL328 features are highlighted below.
Virtual Private Networking
The FVL328 Firewall provides a secure encrypted connection between your local network and
remote networks or clients. Its VPN features include:
•
VPN Wizard: Simplifies VPN setup, uses VPNC defaults.
•
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:
•
Firewall Policies: A firewall policy can be set for each of the 7 private LAN IPs
•
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
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. You can also create up to four groups, each with keyword blocking.
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 WAN
interfaces are 10/100 Mbps, autosensing, and capable of full-duplex or half-duplex operation.

Introduction
May 2004, 202-10030-02
The firewall incorporates Auto Uplink
TM
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 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:
•
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. IP-MAC address locking ensures the same PC always gets the same IP
address.
•
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. There is a
checkbox to disable this feature.
•
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. The FVL328 now supports fixed IP with login.
•
Point-to-Point Tunneling Protocol PPTP login support for European ISPs and BigPond login
for Telstra cable in Australia.
