An entry device for communicating external network signals between an in-home network and an external network. The entry device includes a signal blocking and communication device in communication with an input port, a first network port, and a second network port. The signal blocking and communication device is configured to transmit the external network signals bidirectionally between the input port and the first network port, block in-home network signals from transmission from the first network port to the input port, while allowing the external network signals to be transmitted to the input port, block the in-home network signals from transmission to the input port, while allowing the external network signals to be transmitted to the input port, and transmit the in-home network signals between the first network port and the second network port.
