Chapter 1
Introduction
The ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336G connects your local
area network (LAN) to the Internet through one or two external broadband access devices such as
cable modems or DSL modems. Dual wide area network (WAN) ports allow you to increase
throughput to the Internet by using both ports together, or to maintain a backup connection in case
of failure of your primary Internet connection.
As a complete security solution, the FVS336G incorporates a powerful and flexible firewall to
safeguard your network, while providing advanced IPsec and SSL VPN technologies for secure
and simple remote connections.

v1.0, January 2010
• Easy, web-based setup for installation and management.
• Front panel LEDs for easy monitoring of status and activity.
• Flash memory for firmware upgrade.
• Internal universal switching power supply.
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.
• Virtual 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.
