•
The WGT624 v3 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 v3 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 4-port 10/100 switch, the WGT624 v3 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 Uplink
TM
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 v3 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
