If a user is not connected to a trusted Wi-Fi network or if the
URLStringProbe fails none of the existing dictionaries match.
According to the Apple Configuration Profile Reference[1] section "VPN
Payload > On Demand Rules Dictionary Keys" a default behavior for
unknown networks with no matching criteria should always be set as the
last dictionary in the array. The current default behavior is to allow a
connection to occur, but this behavior is not guaranteed.
Tear down the VPN connection and do not reconnect on demand as long as
the catch-all dictionary matches to guarantee the default behavior and
more specifically allow users to access captive portals.
