Bacnet UDP forwarding on 5412
ip routing
ip udp-bcast-forward
no access control between the vlans
and below on each vlan
ip forward-protocol udp 10.47.94.11 47808
The bacnet device (HVAC controller) is 10.47.94.11
We can ping the device from other vlans, but the udp 47808 traffic does not seem to flow so the application on the laptop cannot see the bacnet controllers. Only works when the laptop is in the same vlan as the bacnet devices.
Suggestions on what to try next

Re: Bacnet UDP forwarding on 5412
What you've done so far looks right, but the packet capture will really show you what's going on.

Re: Bacnet UDP forwarding on 5412
The client(s) seem to be using a Layer-2 protocol only.
Is there anything anything you can reconfigure on the client to make it talk IP?
