Manually Configuring your Router
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.
