4.6Advanced (for advance user only)

The Lynx L-210 supports a host of advanced features. For basic Lynx L-210 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-thru the Lynx L-210 for applications using the UPnP protocol. This feature requires one active DSL connection. In 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, click Advanced and under Advanced, select UPnP. This will bring up the screen shown in Figure 13. You must enable UPnP and then select which connection will utilize UPnP. In this case the PPPoA connection is enabled.
