up.forwardServiceRegistration	bool	true
up.forwardProtocolRegistration	bool	true
up.interfaceMapping	object	{}	Maps network interface names to connected submodule names (e.g. {“eth0”: “bridging”}), overrides automatically learned dispatching; * overrides all learned network interfaces, ? overrides default
up.serviceMapping	object	{}	Maps protocols to connected submodule names (e.g. {“ethernetmac”: “bridging”}), overrides automatically learned dispatching; * overrides all learned services, ? overrides default
