USING THE WEB-BASED ADVANCED USER INTERFACE
Enabling/Disabling NAT (Network Address Translation)
NOTE: This advanced feature should be employed by advanced users only. 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 not affect
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.
