ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual • Logs security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the firewall to email the log to you at specified intervals. You can also configure the firewall to send immediate alert messages to your email address or email pager whenever a significant event occurs. 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 FVS318G incorporates Auto UplinkTM 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 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 VPN firewall supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, refer to "Internet Configuration Requirements" on page C-3. • IP Address Sharing by NAT. The VPN firewall allows many 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. • 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 PC. • Quality of Service (QoS) support for traffic prioritization. Introduction 1-3 1.1 November, 2009
