ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual
Introduction 1-3
v1.1, August 2010
• Keyword Filtering. With its URL keyword filtering feature, the FVS318G prevents
objectionable content from reaching your PCs. The VPN firewall allows you to control access
to Internet content by screening for keywords within Web addresses. You can configure the
VPN firewall to log and report attempts to access objectionable Internet sites.
Security Features
The FVS318G 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 VPN 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.
• DMZ port. Incoming traffic from the Internet is normally discarded by the VPN firewall
unless the traffic is a response to one of your local computers or a service for which you have
configured an inbound rule. Instead of discarding this traffic, you can have it forwarded to one
computer on your network.
Autosensing Ethernet Connections with Auto Uplink
With its internal 8-port 10/100/1000 Mbps switch and 10/100/1000 WAN port, the FVS318G can
connect to either a 10 Mbps standard Ethernet network, a 100 Mbps Fast Ethernet network, or a
1000 Mbps Gigabit Ethernet network. The LAN and WAN interfaces are autosensing and capable
of full-duplex or half-duplex operation.
The VPN 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.
