ProSafe 802.11g Wireless VPN Firewall FVG318 Reference Manual
1-4 Introduction
v1.0, September 2007
•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.
•Point-to-Point Protocol 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 Entersys or WinPOET on your PC.
Easy Installation and Management
You can install, configure, and operate the ProSafe 802.11g W ireless VPN Firewall 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.
•Diagnostic functions. The firewall incorporates built-in diagnostic functions such as Ping,
DNS lookup, and remote reboot.
•Remote management. The firewall allows you to login to the Web Management Interface
from a remote location on the Internet. For 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.
