Scenario 1: Two BACnet networks on different Ethernet ports

BACnet networks are logically routed and physically separated. BACnet routing is only possible between the Ethernet ports: /IP on WAN and /SC on LAN, separating secure (BACnet network1) from unsecure BACnet traffic (BACnet network 3).
Configure flexible ports

The WAN port has unencrypted BACnet/IP traffic and is not intended to use for external network access.
