Reference Manual for the 108 Mbps Wireless Firewall Router WGT624
•The WGT624 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 WGT624 wireless 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.
Autosensing Ethernet Connections with Auto Uplink
With its internal
The router 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 also 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 WGT624 wireless router supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, refer to Appendix B, “Network, Routing, Firewall, and Basics.”
