Enabling/Disabling NAT (Network Address Translation)
Note: This advanced feature should be employed by advanced users only.
Before enabling this function, MAKE SURE YOU HAVE SET THE
ADMINISTRATOR PASSWORD. Network Address Translation (NAT) is the
method by which the Router shares the single IP address assigned by your
ISP with the other computers on your network. This function should only be
used if your ISP assigns you multiple IP addresses or you need NAT disabled
for an advanced system configuration. If you have a single IP address and
you turn NAT off, the computers on your network will not be able to access
the Internet. Other problems may also occur. Turning off NAT will disable your
firewall functions.
Enabling/Disabling UPnP
UPnP (Universal Plug-and-Play) is yet another advanced feature offered by
your Belkin Router. It is a technology that offers seamless operation of voice
messaging, video messaging, games, and other applications that are UPnP-
compliant. Some applications require the Router’s firewall to be configured
in a specific way to operate properly. This usually requires opening TCP and
UDP ports, and in some instances, setting trigger ports. An application that
is UPnP-compliant has the ability to communicate with the Router, basically
“telling” the Router which way it needs the firewall configured. The Router
ships with the UPnP feature disabled. If you are using any applications that
are UPnP-compliant, and wish to take advantage of the UPnP features, you
can enable the UPnP feature. Simply select “Enable” in the “UPnP Enabling”
section of the “Utilities” page. Click “Apply Changes” to save the change.
