BACNET IP and IP filters comm

[ALEJANDRO]

Good morning,

I have two questions. The first concerns exporting data via BACnet IP.

I have a building with three Logic Machine 5 controllers connected. Each controller has been assigned a static IP address of the following type:

192.168.0.11

192.168.0.12

192.168.0.13

We have also created a VPN using the OpenVPN client to access it through the router located in the building.

My question is this: we need all three Logic Machines to export data via BACnet IP to a remote BMS. For some reason, only Logic Machine number one is exporting data. I'm not sure what I'm doing wrong, but I need Logic Machines 2 and 3 to also export a series of group IP addresses.

My second question concerns the filters. The group addresses loaded into logic machines 1, 2, and 3 are exactly the same. This is because we've placed the SCADA screens on logic machine 1, so logic machines 2 and 3 have to send data to logic machine 1 to be displayed on the screen loaded on logic machine 1.

My question here is this: I more or less understand, but I want to be sure. I want the following to happen:

LM2 and LM3 send data to LM1.

The data sent to LM1 should not be sent back to LM2 and LM3.

LM1 does not send data to LM2 and LM3.

How should the IP filters be configured? Thank you very much for everything.

BACnet:
Make sure that each LM has a unique Device ID (System config > Network > BACnet settings).

KNX/IP filtering:
Make sure that each LM has a unique KNX address (System config > Network > KNX connection).
On LM2 and LM3 set "IP > Local" SRC policy to "Drop" and put LM1 address into the "Ind. address list". You can also block LM2 from LM3 and LM3 from LM2 the same way if needed.

BACnet:

I'll send you LMs IDs with pictures

Use port 47808 for all devices. LM2 and LM3 use a different port number so it does not work.
