Extensive Protocol Support; Easy Installation And Management - NETGEAR ProSafe DGFV338 Reference Manual

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 (RIP).
• 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.
• 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.
