Default firewall settings

Ex-factory there is just one entry in the firewall rule table, the “WINS rule”. This rule prevents unwanted connections over the default route (usually to the Internet) by means of the NetBIOS protocol. Windows networks send requests to the network at regular intervals to find out if the known stations are still available. In combination with time-based billing of a network connection, this results in unwanted connection being setup.

Note: The device can prevent unwanted connections, including those for network connectivity, by using its integrated NetBIOS proxy to pretend to respond to queries for resources until an actual access takes place.
