4.6 Advanced (For Advance User Only)
The ADSL router supports a host of advanced features. For basic ADSL router functionality, the
user does not need to utilise 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 ADSL router for applications
using the UPnP protocol. This feature requires one active ADSL connection. In the presence of
multiple ADSL connections, select the one over which the incoming traffic will be present, for
example the default Internet connection.
