Devices on the same subnet can address
To communicate with devices on another subnetwork, the traffic must be routed through a router device's
WAN port. When a device needs to communicate with an IP address that is not on the same network, it sends
the packet to the Default Gateway, which is usually the subnet's Router.
Note: Some BACnet services use "broadcasts" (e.g. "
are "blocked". As a result,
BACnet/IP network of 2 or more
Device (BBMD) must be used.
