Bluetooth generating multicast traffic on LAN


  • I have my AmpliFI HD in bridge mode and also have two Mesh Points.

    In trying to clean up logs on my firewall I noticed a bunch of traffic using and autoconfig address to MDNS (224.0.0.251) getting blocked.

    I performed a packet capture on this and discovered the MAC address for the source traces back to the Bluetooth MAC address on the base.

    I would not expect bluetooth traffic to actually also bridge into the LAN side but it appears to be happening. This could also create a security vulnerability where connecting to the device via Bluetooth also bridges into the users LAN.

    FYI, running beta firmware 3.4.3
