The FVS124G ProSafe VPN Firewall 25 with 4 Gigabit LAN and Dual WAN Ports with 4 port switch connects your local area network (LAN) to the Internet through an external access device such as a cable modem or DSL modem.

The FVS124G is a complete security solution that protects your network from attacks and intrusions. Unlike simple Internet sharing firewalls that rely on Network Address Translation for security, the FVS124G uses Stateful Packet Inspection for Denial of Service (DoS) attack protection and intrusion detection. The FVS124G VPN Firewall provides you with multiple Web content filtering options, plus browsing activity reporting and instant alerts -- both via e-mail. Network administrators can establish restricted access policies based on time-of-day, Website addresses and address keywords.

With minimum setup, you can install and use the firewall within minutes. The FVS124G VPN Firewall provides the following features:

• 2 10/100 Mbps ports for an Ethernet connection to a WAN device, such as a cable modem or DSL modem.

• Dual WAN ports provide for increased system reliability and provide load balancing.

• Support for up to 10 VPN tunnels.

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

• URL keyword Content Filtering and Site Blocking Security.

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

• Built in 4-port 10/100/1000 Mbps switch.

• Extensive Protocol Support.

• Login capability.

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

• Flash memory for firmware upgrade.

Dual WAN Ports for Increased Reliability or Outbound Load Balancing

The FVS124G VPN Firewall has two broadband WAN ports, WAN1 and WAN2, each capable of operating independently at speeds of either 10 Mbps or 100 Mbps. The two WAN ports let you 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 the outgoing traffic. The firewall balances users between the two lines for maximum bandwidth efficiency.

See “Network Planning” on page 3-1 for the planning factors to consider when implementing the following capabilities with dual WAN port gateways:

• Inbound traffic (e.g., port forwarding, port triggering)

• V irtual private networks

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the FVS124G 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 FVS124G will log 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 email address or email pager whenever a significant event occurs.

• With its URL keyword filtering feature, the FVS124G 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 FVS124G 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. You can specify forwarding of single ports or ranges of ports.

• Powerful Firewall Rules Both inbound and outbound traffic can be controlled tightly by defining your own rules regarding permitted users, services, protocols, schedules, and destinations.

Autosensing Ethernet Connections with Auto Uplink

With its internal 4-port 10/100/1000 switch, the FVS124G can connect to either a 10 Mbps standard Ethernet network, a 100 Mbps Fast Ethernet network, or a 1000 Mbps Gigabit Ethernet. Both the LAN and WAN interfaces are autosensing and capable of full-duplex or half-duplex operation.

The firewall incorporates Auto Uplink 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.

Extensive Protocol Support

The FVS124G VPN Firewall supports the Transmission Control Protocol/Internet Protocol (TCP/ IP) and Routing Information Protocol

Appendix B, “Network, Routing, Firewall, and Basics.”

• IP Address Sharing by NAT The FVS124G 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 FVS124G 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.

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

• 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.

Easy Installation and Management

You can install, configure, and operate the FVS124G ProSafe VPN Firewall 25 with 4 Gigabit LAN and Dual WAN Ports 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 FVS124G VPN Firewall automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account.

•VPN Wizard The FVS124G VPN Firewall includes the NETGEAR VPN Wizard to easily configure VPN tunnels according to the recommendations of the Virtual Private Network Consortium (VPNC) to ensure the VPN tunnels are interoperable with other VPNC-compliant VPN routers and clients.

•SNMP The FVS124G VPN Firewall supports the Simple Network Management Protocol (SNMP) to let you monitor and manage log resources from an SNMP-compliant system manager. The SNMP system configuration lets you change the system variables for MIB2.

• Diagnostic functions The firewall incorporates built-in diagnostic functions such as Ping, Trace Route, 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 FVS124G VPN Firewall’ s front panel LEDs provide an easy way to monitor its status and activity.

Default Factory Settings

When you first receive your FVS124G, the default factory settings will be set as shown in

Table 2-1 below. You can restore these defaults with the Factory Defaults restore switch on the

front panel — see “The Router’s Front Panel” on page 2-6.

• Pressing this switch until the TEST LED blinks (approximately 10 seconds) causes the firewall to restore all factory default settings and reboot.

• A shorter press and release causes the firewall to merely reboot.
