What Is the ProSafe Wireless-N 8-Port Gigabit VPN
Firewall FVS318N?
The ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N, hereafter referred to as the
wireless VPN firewall, connects your local area network (LAN) and wireless LAN (WLAN) to
the Internet through an external broadband access device such as a cable or DSL modem,
satellite or wireless Internet dish, or another router. A 2.4-GHz radio supports wireless
connections in 802.11n mode with support for legacy clients in 802.11b and 802.11g mode.
The wireless VPN firewall routes both IPv4 and IPv6 traffic. A powerful, flexible firewall
protects your IPv4 and IPv6 networks from denial of service (DoS) attacks, unwanted traffic,
and traffic with objectionable content. IPv6 traffic is supported through 6to4 and Intra-Site
Automatic Tunnel Addressing Protocol (ISATAP) tunnels.
The wireless VPN firewall provides advanced IPSec and SSL VPN technologies with support
for up to 12 IPSec VPN tunnels and 5 SSL VPN tunnels, as well as L2TP support for easy
and secure remote connections. The use of Gigabit Ethernet WAN and LAN ports ensures
high data transfer speeds.
