• Internet access via either the internal ADSL modem or through the Ethernet port connected to an external modem.

• Auto Rollover Mode between the internal ADSL modem and the external 10/100 ethernet WAN port. If the primary connection fails, the DGFV338 can automatically establish a backup connection via the secondary connection.

A Powerful, True Firewall with Content Filtering

DGFV338 is a true firewall, using stateful packet inspection to defend against 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 DGFV338 will log security events such as blocked incoming traffic, 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 DGFV338 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 NETGEAR ProSafe DGFV338 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.

• 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.

Virtual Private Networking (VPN)

The NETGEAR ProSafe DGFV338 provides a secure encrypted connection between your local area network (LAN) and remote networks or clients. It includes the following VPN features:

• Supports 50 IPSec VPN tunnels.

• Supports industry-standard VPN protocols – The DGFV338 supports standard Manual or IKE keying methods, standard MD5 and SHA-1 authentication methods, and stand ard DES, 3 DES and AES encryption methods.

• Supports 256-bit AES encryption for maximum security.

• The VPN Wizard configuration is based on the Virtual Private Network Consortium (VPNC) recommended settings.

Autosensing Ethernet Connections with Auto Uplink

With its internal 8-port 10/100 switch, the DGFV338 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.

Introduction 1-3

v1.0, April 2007

DGFV338 ProSafe Wireless ADSL Modem VPN Firewall Router Reference Manual

The firewall incorporates Auto Uplink technology. Each Ethernet port will automatically 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 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 NETGEAR ProSafe DGFV338 supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol

• IP Address Sharing by NAT. The DGFV338 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 DGFV338 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).

• 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.

• PPP over ATM (PPPoA). PPPoA is an asynchronous point-to-point protocol for connecting to the Internet over ADSL.

Easy Installation and Management

You can install, configure, and operate the ProSafe Wireless ADSL Modem VPN Firewall Router 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.

DGFV338 ProSafe Wireless ADSL Modem VPN Firewall Router Reference Manual

• Smart Wizard. The NETGEAR ProSafe DGFV338 automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account.

• VPN Wizard. The NETGEAR ProSafe DGFV338 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 VPNCcompliant VPN routers and clients.

• SNMP. The NETGEAR ProSafe DGFV338 supports the Simple Network Management Protocol (SNMP) to let you monitor and manage 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, Packet Capture, DNS lookup, and remote reboot.

• Remote management. The firewall allows you to securely log in 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 front panel LEDs of the NETGEAR ProSafe DGFV338 provide an easy way to monitor its status and activity.
