Allow PING from the Internet PING is a utility, which is used to determine
whether a device is active at the specified IP address. PING is normally used to test
the physical connection between two devices, to ensure that everything is working
correctly.
By default the Gateway has PING disabled in order to make the device more
difficult to find on the Internet and less prone to attack.
This feature is enabled by clicking on the check box so that a tick can be seen and
