4.6 Advanced
The router supports a host of advanced features. For basic router functionality, the user does not need to utilize these
advanced features. The features help with routing, security, port configuration, and plug and play capability.
4.6.1 UpnP
UPnP NAT and Firewall Traversal allow traffic to pass through the router for applications using the UPnP protocol. This
feature requires one active DSL connection. In the presence of multiple DSL connections, select the one over which the
incoming traffic will be present (for example, the default Internet connection).
To enable UPnP, you must first have a WAN connection configured. Once a WAN connection is configured, go to the
Home screen. Click on Advanced, then select UPnP. This will bring up the screen shown in Figure 12. You must enable
UPnP and then select which connection will utilize UPnP. In this case the Bridge connection is enabled.
