Abstract: A device identification module identifies devices on a remote network, where the remote network may use Network Address Translation techniques. The device identification module can receive a list of devices on the remote network. The devices in the remote network can be identified by the device classification module based, at least in part, on the device classification and one or more of Dynamic Host Configuration Protocol (DHCP) information for the remote network, port sequences used in Network Address Translation on the remote network, and a live Uniform Resource Locator (URL) check performed on the remote network.

Abstract: A content filter setting method includes enabling a user to choose a setting of a filter for a particular application in a user interface of a user device. The setting of the filter is received from the user via the user interface, and a model is applied to determine a plurality of default settings of a plurality of filters of the particular application based on the setting of the filter and the identifying information of the user. The plurality of default settings is displayed in the user interface, and modified settings of the default settings are received via the user interface.
