ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual • Advanced IPsec and SSL VPN support • Advanced stateful packet inspection (SPI) firewall with multi-NAT support • Easy, web-based setup for installation and management • Front panel LEDs for easy monitoring of status and activity • Flash memory for firmware upgrade • AC-DC power adapter for low current draw A Powerful, True Firewall with Content Filtering Unlike simple Internet sharing NAT routers, the SRXN3205 is a true firewall, using stateful packet inspection (SPI) to defend against hacker attacks. Its firewall features include: • Automatically detects and thwarts denial of service (DoS) attacks such as Ping of Death and SYN Flood. • Blocks unwanted traffic from the Internet to your LAN. • Blocks access from your LAN to Internet locations or services that you specify as off-limits. • Prevents objectionable content from reaching your PCs. You can control access to Internet content by screening for Web services, Web addresses, and keywords within Web addresses. You can configure the firewall to log and report attempts to access objectionable Internet sites. • Permits scheduling of firewall policies by day and time. • 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 5-port 10/100/1000 Mbps switch and 10/100/1000 WAN port, the SRXN3205 can connect to either a 10 Mbps standard Ethernet network, a 100 Mbps Fast Ethernet network, or a 1000 Mbps Gigabit Ethernet network. The five LAN and WAN interfaces are autosensing and capable of full-duplex or half-duplex operation. The SRXN3205 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. 1-2 Introduction v1.0, October 2008
