Abstract
Methods and apparatus for implementing and controlling a firewall in a router, e.g., a home router, are described. Network traffic through a router is monitored and analyzed the network to identify devices and the type of one or more of the identified devices. In some embodiments, the device type identification is performed using a neural network. The router stores a set of firewall templates. At different times a different templates are applied, e.g. based on mode of operation, user selection, and/or time information. Rules in a firewall template, applicable at a given time to traffic corresponding to identified devices, that are attempting to send or receive via the router, are applied. Different rules may, and sometimes do, apply to different device type classifications.
