USING THE WEB-BASED ADVANCED USER INTERFACE
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.
