Dual WAN Ports for Increased Reliability or Outbound Load Balancing

The FVS336G has two broadband WAN ports. The second WAN port allows you to connect a
second broadband Internet line that can be configured on a mutually-exclusive basis to:

• Provide backup and rollover if one line is inoperable, ensuring you are never disconnected.

• Load balance, or use both Internet lines simultaneously for outgoing traffic. The FVS336G
balances users between the two lines for maximum bandwidth efficiency.

See “Network Planning for Dual WAN Ports” on page B-1 for the planning factors to consider
when implementing the following capabilities with dual WAN port gateways:

• Single or multiple exposed hosts.

• V irtual private networks.

Advanced VPN Support for Both IPsec and SSL

The FVS336G supports IPsec and SSL virtual private network (VPN) connections.

• IPsec VPN delivers full network access between a central office and branch offices, or
between a central office and telecommuters. Remote access by telecommuters requires the
installation of VPN client software on the remote computer.

– IPsec VPN with broad protocol support for secure connection to other IPsec gateways and

clients.

– Bundled with the single-user license of the NETGEAR ProSafe VPN Client software

(VPN01L)

– Supports 25 concurrent IPsec VPN tunnels.

• SSL VPN provides remote access for mobile users to selected corporate resources without
requiring a pre-installed VPN client on their computers.

– Uses the familiar Secure Sockets Layer (SSL) protocol, commonly used for e-commerce

transactions, to provide client-free access with customizable user portals and support for a
wide variety of user repositories.

– Browser based, platform-independent, remote access through a number of popular

browsers, such as Microsoft Internet Explorer or Apple Safari.

– Provides granular access to corporate resources based upon user type or group

membership.

– Supports 10 concurrent SSL VPN sessions.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the FVS336G is a true firewall, using stateful packet
inspection (SPI) to defend against hacker attacks. Its firewall features include:

• Automatically detects and thwarts denial of service (DoS) attacks such as Ping of Death and
SYN Flood.

• 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.

• Prevents objectionable content from reaching your PCs. You can control access to Internet
content by screening for Web services, Web addresses, and keywords within Web addresses.
You can configure the FVS336G to log and report attempts to access objectionable Internet
sites.

• Permits scheduling of firewall policies by day and time.

• Logs security events such as blocked incoming traffic, port scans, attacks, and administrator
logins. Y ou can configure the FVS336G to e-mail the log to you at specified intervals. You can
also configure the FVS336G to send immediate alert messages to your e-mail address or
e-mail pager whenever a significant event occurs.

Autosensing Ethernet Connections with Auto Uplink

With its internal 4-po rt 10/100/1000 Mbps switch and dual 10/100/1000 WAN ports, the FVS336 G
can connect to either a 10 Mbps standard Ethernet network, a 100 Mbps Fast Ethernet network, or
a 1000 Mbps Gigabit Ethernet network. The four LAN and two WAN interfaces are autosensing
and capable of full-duplex or half-duplex operation.

The FVS336G incorporates Auto Uplink
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 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 FVS336G supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and
Routing Information Protocol

Configuration Requirements” on page B-3.

• IP Address Sharing by NAT. The FVS336G allows many 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 FVS336G 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 FVS336G
provides its own address as a DNS server to the attached PCs. The FVS336G 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 PC.

• Quality of Service (QoS). Support for traffic prioritization.

(RIP). For further information about TCP/IP, refer to “Internet

Easy Installation and Management

You can install, configure, and operate the FVS336G 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 FVS336G from almost any type of personal computer, such as Windows, Macintosh, or
Linux. Online help documentation is built into the browser-based Web Management Interface.

• Auto Detection of ISP. The FVS336G automatically senses the type of Internet connection,
asking you only for the information required for your type of ISP account.

• VPN Wizard. The FVS336G includes the NETGEAR VPN Wizard to easily configure IPsec
VPN tunnels according to the recommendations of the Virtual Private Network Consortium
(VPNC) to ensure the IPsec VPN tunnels are interoperable with other VPNC-compliant VPN
routers and clients.
