Open the Promiscuous mode of interface
Toggling promiscuous mode will make a (wireless) NIC forward all traffic it receives to the OS for further processing. This is opposite to “normal mode” where a NIC will drop frames it is not intended to receive. It is most often used for advanced network troubleshooting and packet sniffing.
sudo vim /etc/systemd/system/promiscuous@.service
