DIR-100 Ethernet Broadband Router
UPnP
UPnP supports zero-configuration networking and automatic discovery for many types of networked devices.
When enabled, it allows other devices that support UPnP to dynamically join a network, obtain an IP
address, convey its capabilities, and learn about the presence and capabilities of other devices. DHCP and
DNS service can also be used if available on the network. UPnP also allows supported devices to leave a
network automatically without adverse effects to the device or other devices on the network.
Diverse networking media including Ethernet, 802.11b/g Wireless, Firmware, phone line and power line
networking can support UPnP. To enable UPnP, tick the Enable UPnP checkbox.
WAN Ping
This feature allow users to either allow or block a Ping test from outside computers looking to check the
connectivity of your device. This is usually attempted by hackers trying to access your router or computer
from a remote device on the WAN side of the connection. Tick the Enable WAN Ping Respond checkbox
to allow WAN pinging of your device.
WAN Port Speed
This section allows the user to set the wire speed over which the router will transmit packets. The user has
three options:
10Mbps – Selecting this option from the drop-down menu will set the wire speed at 10 megabytes
per second.
100Mbps – Selecting this option from the drop-down menu will set the wire speed at 100 megabytes
per second.
10/100 Mbps Auto – Selecting this option from the drop-down menu will allow the wire speed to be
automatically set by the Router depending on the wire speed available at any given time.
NAT
Network Address Translation (NAT) can be disabled on the Router. For normal use as a router it is
recommended that NAT be left at the default setting, enabled. Some applications might not function well
with NAT. Usually this problem can be overcome using port forwarding or DMZ. If NAT is disabled, the
Router will only allow a single computer or server to use the Router for Internet access. Without NAT the
DIR-100 functions as a simple bridge device.
