Abstract: Aspects of the disclosure provide an electronic device that includes a transceiver circuit, an interface circuit and a modulator-demodulator (modem) circuit. The transceiver circuit is configured to transmit and receive wireless signals to/from a first network that uses a first network address space. The interface circuit is configured to interconnect the electronic device with one or more devices to form a second network using a second network address space. The modem circuit is coupled to the transceiver circuit to modulate/demodulate signals for wireless communication. The modem circuit is configured to provide a packet of a header characteristic for a network address translation between the first network address space and the second network address space, receive, after the network address translation, a modified packet corresponding to the packet, determine a modification associated with the header characteristic and apply the modification to one or more other packets having the header characteristic.
