Autosensing Ethernet Connections with Auto Uplink
With its internal eight-port 10/100 switch, the FVS114 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. 
The firewall incorporates Auto Uplink
TM
 technology. Each Ethernet port automatically senses 
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 then configures 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 FVS114 VPN Firewall supports the Transmission Control Protocol/Internet Protocol (TCP/IP) 
and Routing Information Protocol (RIP). For further information about TCP/IP, refer to 
.”
IP Address Sharing by NAT
 
The FVS114 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 FVS114 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.
