NETGEAR WGR614v7 manual Security, Autosensing Ethernet Connections with Auto Uplink

54 Mbps Wireless Router WGR614v7 Reference Manual

•The WGR614v7 prevents objectionable content from reaching your computers. 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 wireless router is equipped with several features designed to maintain security, as described in this section.

•Computers 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 computers on the LAN.

•Port Forwarding with NAT

Although NAT prevents Internet locations from directly accessing the computers on the LAN, the router allows you to direct incoming traffic to specific computers 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 4-port 10/100 switch, the WGR614v7 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.

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 computer 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 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.”
