Abstract:
An apparatus comprises a first network interface unit, a second network interface unit, and a preconfigured firewall unit. The first network interface unit is configured for communicating with a local network of a user. The second network interface unit is configured for communicating with a designated embedded device of the user. The preconfigured firewall unit is configured for transparently filtering packets of network traffic from the first network device to the second network device. The filtering at least in part is accomplished in a stateful manner without configuration by the user.
