I didn’t read the mail. Thank you very much. This is very helpful. Replace the destination MAC address with the bridge interface MAC address to get the packet to the network layer. But there is a problem here, that is, the specified MAC address is fixed, this is not universal, I have to modify the command on different devices. Is there a way for nftables to automatically get the MAC address of the interface?
