Introduction

The firewall incorporates Auto Uplink
TM
technology. Each local 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.

Protocol Support
The FVL328 supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP).

further information on TCP/IP. Supported protocols include:
•
The Ability to Enable or Disable IP Address Sharing by NAT
The FVL328 allows several networked computers 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. This feature can also be turned off completely for using the FVL328 in settings
where you want to manage the IP address scheme of your organization.

where you want to manage the IP address scheme of your organization.
•
Automatic Configuration of Attached computers by DHCP
The FVL328 dynamically assigns network configuration information, including IP, gateway,
and domain name server (DNS) addresses, to attached computers using Dynamic Host
Configuration Protocol (DHCP). This feature greatly simplifies configuration of computers on
your local network. IP-MAC address locking ensures the same PC always gets the same IP
address.

address.
•
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 computers. The firewall obtains actual DNS addresses
from the ISP during connection setup and forwards DNS requests from the LAN. There is a
checkbox to disable this feature.

•
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 computer. The FVL328 now supports fixed IP with login.
