BACnet with one RUT906 only

NETWORKING SOLUTIONS

Hello

we are just discovering the RUT906 for our Projects using BACnet. I have found only this description: https://wiki.teltonika-networks.com/view/BACnet_configuration_example

Than means i need two RUT906 or at least an other BBMD device.

Our requirement is the following:
BACnet controller (or Yabe e.g.) ↔ LAN1 ↔ RUT906 ↔ LAN2 ↔ our BACnet devices

The LAN1 is typically a customer LAN, RUT906 is connected via WAN port.
The LAN2 is our own local network using RUT906 LAN.

Is this configuration possible with RUT906 (or any other Teltonika supporting BACnet).

regards
Roland

Hello,

Apologies for the delay. Could you kindly provide a simple topology diagram including the IP addresses of your planned setup? From your current description, as I understand it, you have two separate networks, with the BACnet controller connected to LAN1 (customer network) and your BACnet server on LAN2, correct?

At first glance, this configuration should be achievable with the RUT906; however, having the full topology and addressing plan would help to confirm the details

Best regards,

Hi Martynas

thanks for your reply. I have the topology diagram as apendet. So far we need the access for the customer for our BACnet applications behind the Teltonika router.
Via VPN we connect our self to the BACnet devices for general application configuration. Here no access to BACnet necessary.

The used IP addresses are examples, but a mirror of our application.

Hi,
There’s a similar question answered in BACnet IP <- Just one Teltonika RUTX -> Cloud Server

I am testing the same setup with RUT965, but there’s a problem: when sending a reply to “register as foreign device” and “whois” packets sent by YABE, the Teltonika changes port and thus the reply is dropped in firewall. Can anyone please comment the situation?

Here’s a tcpdump (192.168.2.5 is YABE, 192.168.71.5 is Teltonika):\
