1. A network-communication method comprising:
- detecting network activity between a router of a local area network and a wide area network, the local area network comprising a plurality of client devices;
decoding the network activity;
responsive to the decoding step, obtaining at least a source network address for the network activity, the source network address being a network-layer address of the router of the local area network;
using the source network address to establish a transparent networking bridge between the local area network and the wide area network, the using step comprising assigning to the transparent networking bridge a network-layer address having a same range as the source network address;
wherein the transparent networking bridge establishes a connection with at least one server located on the wide area network;
wherein the transparent networking bridge is unknown to the plurality of client devices on the local area network;
wherein the transparent networking bridge has no network-layer address or device address specifically assigned thereto; and
providing security services to the plurality of client devices on the local area network via the at least one server;
wherein the detected network activity is outbound network activity from the local area network to the wide area network;
wherein the obtaining step comprises obtaining a device address of a first gateway of the wide area network; and
wherein the first gateway of the wide area network belongs to a network service provider providing access to the wide area network.

15. A method comprising:
-
detecting network activity from a router of a local area network to a wide area network, the local area network comprising a plurality of client devices; decoding the network activity; responsive to the decoding step, obtaining a source network address for the network activity and a device address of a first gateway on the wide area network, the source network address being a network-layer address assigned to a wide-area-network connection of the router; establishing a transparent networking bridge between the local area network and the wide area network, the establishing step comprising assigning to the transparent networking bridge a network-layer address having a same range as the source network address; establishing a connection with at least one server on the wide area network; via the transparent networking bridge, utilizing the connection with the at least one server to provide one or more network-based security services to the plurality of client devices; wherein the transparent networking bridge is unknown to the plurality of client devices on the local area network; and wherein the transparent networking bridge has no network-layer address or device address specifically assigned thereto. - View Dependent Claims (16)
