•
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
.
•
IP Address Sharing by NAT.
The WPNT834 router allows several networked computers to share an Internet account using
only a single IP address, which your Internet service provider (ISP) may statically or
dynamically assign. This technique, known as NAT, allows the use of an inexpensive single-
user ISP account.
•
Automatic Configuration of Attached Computers by DHCP.
The WPNT834 router dynamically assigns network configuration information, including
IP, gateway, and domain name server (DNS) addresses, to attached computers on the LAN
using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies
configuration of computers on your local network.
•
DNS Proxy.
When DHCP is enabled and no DNS addresses are specified, the router provides its own
address as a DNS server to the attached computers. The router obtains actual DNS addresses
from the ISP during connection setup and forwards DNS requests from the LAN.
