Preliminary Manual for the 108 Mbps Wireless Media Router WGT634U A Powerful, True Firewall with Content Filtering Unlike simple Internet sharing NAT routers, the WGT634U is a true firewall, using stateful packet inspection to defend against hacker attacks. Its firewall features include: • Denial of Service (DoS) protection.Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND Attack, and IP Spoofing. • 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. • The WGT634U prevents objectionable content from reaching your PCs. The router allows you to control access to Internet content by screening for keywords within Web addresses. You can configure the router to log and report attempts to access objectionable Internet sites. Security The WGT634U Wireless Media Router 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 router allows you to direct incoming traffic to specific PCs based on the service port number of the incoming request, or to one designated "DMZ" host computer. You can specify forwarding of single ports or ranges of ports. • Logs security incidents. The WGT634U will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the router to email the log to you at specified intervals. You can also configure the router 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 switch, the WGT634U can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are autosensing and capable of full-duplex or half-duplex operation. 2-4 Introduction Preliminary - Go to http://kbserver.netgear.com/products/wgt634U.asp for final manual
