Reference Manual for the RangeMax 240 Wireless Router WPNT834
2-4 Introduction
v1.1, January 2006
• Keyword screening.
The WPNT834 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 WPNT834 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 WPNT834 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
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 WPNT834 router supports the Transmission Control Protocol/Internet Protocol
(TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, see
“Wireless Communications” in Appendix B.
