Bacnet BBMD – stands for "BACnet Broadcast Management Device." A BBMD is a device that manages the routing of BACnet broadcast messages across different IP subnets. When a BACnet device sends a broadcast message, it is typically sent to all devices on the same subnet, but not to devices on other subnets. However, sometimes it is necessary for broadcast messages to be sent to devices on multiple subnets. This is where a BBMD comes in.

Also, under the '''BIP''' configuration change the '''BIP port to a port of Yabe'''. There are two ways of finding the port of YABE, one way is to look through the traffic with '''Wireshark''' on your PC or '''TCP dump on RUT1 or RUT2'''.

'''Bacnet BIP''' - Bacnet devices can use BIP to communicate with each other over local area networks (LANs), wide area networks (WANs), and the internet. BIP defines how BACnet messages are encapsulated within IP packets and transmitted between BACnet devices over IP networks.

'''Note''': If you restart the YABE software or delete and recreate a new communication device, YABE may use a different port number, in which case you must change the port forward configuration in the router connected to your PC.

By enabling the port forward in the BACnet configuration, you created the port forward rule. Nevertheless, the rule requires some modification. To do that, open the RUT1 WebUI and navigate to '''Network → Firewall → Port Forwards'''. Create a port forward rule to forward UDP packets from RUT2 WAN to the RUT1 LAN address port.
