Option Description
Enable UPnP Determines whether the Gateway uses its UPnP feature to communicate with other devices or
your operating system.
• Enabled = allows the Gateway to use its UPnP feature to communicate with other devices
or your operating system. (default)
• Disabled = prevents the Gateway from using its UPnP feature to communicate with other
devices or your operating system. Also, may be disabled if your operating system does not
support UPnP.
Advertisement Period How often the Gateway broadcasts its UPnP information (if UPnP is enabled). This value can
range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that
control points have current device status at the expense of additional network traffic. Longer
durations can compromise the freshness of the device status, but can significantly reduce
network traffic.
Time To Live A counting mechanism to determine how long a packet is valid before it reaches its
destination. Each time a TCP/IP packet passes through a router, it decrements its Time To
Live count. When the count reaches zero, the packet is dropped by the router. This ensures
that errant routing and looping aimless packets will not flood the network. The number of hops
can range from 1 to 255. The default value is 5 hops, which should be fine for most networks.
If you notice that some devices are not being updated or reached correctly, you might want to
increase this value slightly.
Enable Zero Config Determines whether zero configuration is enabled or disabled. Zero configuration networking
automatically creates a usable Internet Protocol (IP) network, without manual operator
intervention or special configuration servers. It allows nonexpert users to connect computers,
networked printers, and other network devices and expect a functioning network to be
established automatically.
• Enabled = enables support for zero configuration.
• Disabled = disables support for zero-configuration (default)
