Chapter 1

Introduction

The ProSafe VPN Firewall 50 with 8 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 FVS338 is a complete security solution that protects your network from attacks and intrusions. For example, the FVX538 provides support for Stateful Packet Inspection, Denial of Service (DoS) attack protection and multi-NAT support.The VPN firewall supports 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, and share high-speed cable/DSL Internet access for a local network.

The FVS338 is a plug-and-play device that can be installed and configured within minutes.

Key Features

The VPN firewall provides the following features:

• One 10/100 Mbps port for an Ethernet connection to a broadband W AN device, such as a cable modem or DSL modem, and one serial port for a dial-up modem connection to the Internet through the public switched telephone network (PSTN).

• Dual WAN ports (one broadband and one serial) provide for increased system reliability.

• Support for up to 50 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 8-port 10/100 Mbps switch.

• Extensive Protocol Support.

• Login capability.

• SNMP for manageability.

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

• Flash memory for firmware upgrade.

Introduction 1-1

v1.0, January 2007

FVS338 ProSafe VPN Firewall 50 Reference Manual

Full Routing on Both the Broadband and Serial WAN Ports

You can install, configure, and operate the FVS338 to take full advantage of a variety of routing options on both the serial and broadband WAN ports, including:

• Internet access via either the serial or broadband port.

• Auto rollover connectivity (fail-over) through an analog modem connected to the serial port If the broadband Internet connection fails, after waiting for an pre-specified amount of time the FVS338 can automatically establish a backup dial-up Internet connection via the serial port on the firewall.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the FVS338 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 FVS338 will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. Y ou 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 FVS338 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 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.

1-2 Introduction

v1.0, January 2007

FVS338 ProSafe VPN Firewall 50 Reference Manual

• 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.

• Exposed Host (Software DMZ). Incoming traffic from the Internet is normally discarded by the firewall unless the traffic is a response to one of your local computers or a service for which you have configured an inbound rule. Instead of discarding this traffic, you can have it forwarded to one computer on your network.

Autosensing Ethernet Connections with Auto Uplink

With its internal 8-port 10/100 switch, the FVS338 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 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.

technology. Each Ethernet port will automatically sense

Extensive Protocol Support

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

• IP Address Sharing by NAT. The 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 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.

• 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 ProSafe VPN Firewall 50 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 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 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 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 securely login to the Web Management Interface from a remote location on the Internet. For additional 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 VPN firewall’s front panel LEDs provide an easy way to monitor its status and activity.

Maintenance and Support

NETGEAR offers the following features to help you maximize your use of the VPN firewall:

• Flash memory for firmware upgrade

Connecting the FVS338 to the Internet

This section provides instructions for connecting the VPN firewall. Setting up VPN tunnels are covered in Chapter 5, “Virtual Private Networking”:

1. Connect the firewall physically to your network. Connect the cables, turn on your router and wait for the T est LED to go out. Make sure your Ethernet and LAN LEDs are lit. (See the FVS338 ProSafe VPN Firewall 50 Installation Guide on your Resource CD.)

2. Log in to the firewall. After logging in, you are ready to set up and configure your firewall. You can also change your password and enable remote management at this time.

3. Configure the Internet connections to your ISPs. During this phase, you will connect to your ISPs. You can also program the WAN traffic meters at this time if desired.

4. Configure the WAN mode. Select either Primary Broadband with Dialup as backup or

Use only single WAN port—and select the WAN port from the pull-down menu—either Broadband or Dial-up.

5. Configure dynamic DNS on the WAN ports (if needed). Configure your fully qualified domain names during this phase (if required).

6. Configure the WAN options (if needed). Optionally, you can enable each WAN port to respond to a ping. You can also change the factory default MTU size, port speed, and uplink bandwidth. However, these are advanced features and changing them is not usually required.

Connecting the VPN Firewall to Your Network

To physically connect your VPN firewall, refer to the IFVS338 ProSafe VPN Fir ewall 50 Installation Guide (a copy is also available on your Resource CD).

Logging in to the VPN Firewall

Note: To connect to the firewall, your computer needs to be configured to obtain an IP

address automatically via DHCP.
