Problem

After upgrading your IXrouter3 to firmware version 3.29 or higher, your BACnet/IP discovery, broadcast, or search stopped working.

Cause

Firmware 3.29 brings significant changes to the way BACnet/IP works within the IXrouter3.

Solution

In your BACnet/IP software, change the BBMD (BACnet Broadcast Management Device) or FDR (Foreign Device Registration) setting from the IXrouter3's VPN address to its LAN IP address.
