Introduction

This chapter describes the features of the NETGEAR ProSafe Wireless 802.11g VPN Firewall

Model FVG318.

Key Features of the Wireless VPN Firewall

The ProSafe Wireless 802.11g VPN Firewall Model FVG318 with eight-port switch connects your

local area network (LAN) to the Internet through an external access device such as a cable modem

or DSL modem and provides 802.11b/g wireless LAN connectivity.

The FVG318 is a complete security solution that protects your network from attacks and

intrusions. Unlike simple Internet sharing firewalls that rely on Network Address Translation

(NAT) for security, the FVG318 uses stateful packet inspection for Denial of Service attack (DoS)

protection and intrusion detection. The FVG318 allows Internet access for up to 253 users. The

FVG318 wireless VPN firewall provides you with multiple Web content filtering options, plus

browsing activity reporting and instant alerts — both via e-mail. Parents and network

administrators can establish restricted access policies based on time-of-day, Web site addresses

and address keywords, and share high-speed cable/DSL Internet access for up to 253 personal

computers. In addition to NAT, the built-in firewall protects you from hackers.

With minimum setup, you can install and use the firewall within minutes.

The FVG318 wireless VPN firewall provides the following features:

• 802.11g and 802.11b standards-based wireless networking.

• Wireless Multimedia (WMM) support.

• Easy, Web-based setup for installation and management.

• Front panel LEDs for easy monitoring of status and activity.

• Content filtering and site blocking security.

• Built-in eight-port 10/100 Mbps switch.

• Ethernet connection to a WAN device, such as a cable modem or DSL modem.

• Extensive protocol support.

• Flash memory for firmware upgrade.

v1.0, October 2005

802.11g and 802.11b Wireless Networking

The FVG318 wireless VPN firewall includes an 802.11g-compliant wireless access point. The

access point provides:

• 802.11b standards-based wireless networking at up to 11 Mbps.

• 802.11g wireless networking at up to 54 Mbps, which conforms to the 802.11g standard.

• WPA and WPA2 enterprise class strong security with RADIUS and certificate authentication

as well as dynamic encryption key generation.

• WPA-PSK and WPA2-PSK pre-shared key authentication without the overhead of RADIUS

servers but with all of the strong security of WPA and WPA2.

• 64-bit and 128-bit WEP encryption security.

• WEP keys can be generated manually or by passphrase.

• Wireless access can be restricted by MAC Address.

• Wireless network name broadcast can be turned off so that only devices that have the network

name (SSID) can connect.

Wireless Multimedia (WMM) Support

WMM is a subset of the 802.11e standard. WMM allows wireless traffic to have a range of

priorities, depending on the kind of data. Time-dependent information such as video or audio will

have a higher priority than normal traffic. For WMM to function correctly, wireless clients must

also support WMM.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT firewalls, the FVG318 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.

Introduction 2-3

v1.0, October 2005

The FVG318 logs 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 e-mail

address or email pager whenever a significant event occurs.

• With its content filtering feature, the FVG318 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.

Security

The FVG318 wireless VPN firewall is equipped with several features designed to maintain

security, as described in this section.

• PCs Hidden by NAT

NAT opens a temporary path to the Internet for requests originating from the local network.

Requests originating from outside the LAN are discarded, preventing users outside the LAN

from finding and directly accessing the PCs on the LAN.

• Port Forwarding with NAT

Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the

firewall allows you to direct incoming traffic to specific PCs based on the service port number

of the incoming request, or to one designated “DNS” host computer. You can specify

forwarding of single ports or ranges of ports.

Autosensing Ethernet Connections with Auto Uplink

With its internal eight-port 10/100 switch, the FVG318 can connect to either a 10 Mbps standard

Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are

autosensing and capable of full-duplex or half-duplex operation.

The firewall incorporates Auto UplinkTM technology. Each Ethernet port automatically senses

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 then configures 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.

Extensive Protocol Support

The FVG318 wireless VPN firewall supports the Transmission Control Protocol/Internet Protocol

(TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, refer to

“Internet Networking and TCP/IP Addressing:” in Appendix A.”

2-4 Introduction

v1.0, October 2005

• IP Address Sharing by NAT

The FVG318 wireless VPN firewall 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 NAT, allows the use of an

inexpensive single-user ISP account.

• Automatic Configuration of Attached PCs by DHCP

The FVG318 wireless VPN firewall 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.

• Point-to-Point Protocol 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 Entersys or WinPOET on your PC.

Easy Installation and Management

You can install, configure, and operate the ProSafe Wireless 802.11g VPN Firewall Model

FVG318 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 FVG318 wireless VPN firewall automatically senses the type of Internet connection,

asking you only for the information required for your type of ISP account.

• Diagnostic functions

The firewall incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote

reboot.

• Remote management

The firewall allows you to login to the Web Management Interface from a remote location on

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.

• Visual monitoring

The FVG318 wireless VPN firewall’s front panel LEDs provide an easy way to monitor its

status and activity.
