With its URL keyword filtering feature, the FVS124G prevents objectionable content from 
reaching your PCs. The firewall allows you to control access to Internet content by screening 
for keywords within Web addresses. You can configure the firewall to log and report attempts 
to access objectionable Internet sites.
Security
The FVS124G VPN Firewall is equipped with several features designed to maintain security, as 
described in this section.
PCs Hidden by NAT
 
NAT opens a temporary path to the Internet for requests originating from the local network. 
Requests originating from outside the LAN are discarded, preventing users outside the LAN 
from finding and directly accessing the PCs on the LAN.
Port Forwarding with NAT
 
Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the 
firewall allows you to direct incoming traffic to specific PCs based on the service port number 
of the incoming request. You can specify forwarding of single ports or ranges of ports.
Powerful Firewall Rules
 
Both inbound and outbound traffic can be controlled tightly by defining your own rules 
regarding permitted users, services, protocols, schedules, and destinations.
Autosensing Ethernet Connections with Auto Uplink
With its internal 4-port 10/100/1000 switch, the FVS124G can connect to either a 10 Mbps 
standard Ethernet network, a 100 Mbps Fast Ethernet network, or a 1000 Mbps Gigabit Ethernet. 
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 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.
