Feature description: In ARC++ inbound connections are blocked and multicast or broadcast packets from Android will not be forwarded to the LAN through the firewall. It would allow apps like Cast Receiver and Expeditions to establish connections both ways between ARC++ and a pure Android device. Note apps will use the standard APIs and they will be unaware of the ARC++ networking situation.
