ARP/Broadcast not working

lecndav LV 3

Hi, thanks for the guide to port the driver! I have the problem, that the D1 LicheeRV dock with tina linux is not getting any TCP broadcast or ARP messages. Therefore the device is not reachable within the network. But it is working the other way round. So the device is connected, has an IP, can ping the default gateway, has connection to the internet, ... But it is not possible to ping the device from another PC in the network.

"tcpdump arp" does not show any messages besides from the default gateway.

Is this problem familiar to you?
