Enable UPnP
Configures your Gateway as a uPnP Internet gateway. UPnP allows for dynamic connectivity between devices on
a network. A UPnP-enabled device like your Gateway can obtain an IP address, advertise its capabilities, learn
about other connected UPnP devices and then communicate directly with those devices. The same device can
end its connection cleanly when it wishes to leave the UPnP community. The intent of UPnP is to support zero-
configuration, "invisible" networking of devices including intelligent appliances, PCs, printers, and other smart
devices using standard protocols.
•
Check = uPnP is enabled on the Gateway. (
default)
•
Uncheck = uPnP is disabled on the Gateway.
Enable HNAP
Configures your Gateway as a HNAP device. HNAP allows your Gateway to be configured and managed by
remote entities, such as Network Magic or any software application that discovers and manages network devices.
