Reference Manual for the ProSafe Wireless 802.11g VPN Firewall Model FVG318

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.”

FVG318 specifications

The NETGEAR FVG318 is a versatile device that combines a firewall, router, and VPN functionality, making it a powerful solution for small to medium-sized businesses as well as advanced home networking. Its multifunctional capabilities allow users to enjoy high-speed internet access while maintaining secure and private connections.

One of the standout features of the FVG318 is its built-in firewall, which provides essential protection against network threats. The firewall uses Stateful Packet Inspection to monitor and filter incoming and outgoing traffic, ensuring that unauthorized access attempts are thwarted. This is particularly important in safeguarding sensitive business data and personal information from cyber threats.

The device also supports a VPN feature, allowing remote users to connect securely to the network. This is facilitated through IPsec VPN, which supports up to 20 simultaneous VPN tunnels. This capability is invaluable for businesses with employees who work remotely or operate from multiple locations, providing secure access to internal resources no matter where they are.

Another notable characteristic of the FVG318 is its wireless connectivity. It includes high-performance IEEE 802.11g wireless technology, offering users the flexibility to connect multiple devices without the need for physical cables. This feature is ideal for environments where mobility is crucial. The router supports a throughput of up to 54 Mbps, ensuring that users have ample bandwidth for activities such as streaming, video conferencing, and large file transfers.

Additionally, the NETGEAR FVG318 comes equipped with a built-in 4-port Ethernet switch, allowing for direct wired connections to devices like computers and printers. This hybrid functionality means that users have the choice between wired and wireless connections, based on their specific needs and the layout of their workspace.

Setup and management of the FVG318 are user-friendly, with a web-based interface that simplifies the configuration process. This makes it accessible to both tech-savvy users and those less familiar with networking equipment. The device also includes quality of service (QoS) features, allowing priority to be given to essential applications such as VoIP or streaming services.

In summary, the NETGEAR FVG318 is an all-in-one networking device that offers robust security, reliable wireless and wired connections, and flexible remote access capabilities. It is designed to meet the demands of modern networking environments, making it a popular choice for both business and home network users seeking performance and security in one package.
