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
•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
•PPP over ATM (PPPoA). PPPoA is an asynchronous
