Enabling/Disabling Network Address Translation (NAT)
Note: This advanced feature should be modified by advanced users
only.
NAT is the method by which the Router shares the single IP address
assigned by your ISP with the other computers on your network and
is enabled by default. NAT should only be disabled 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. 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.
