I am trying to make Whonix Gateway use a USB network adapter as an external network, instead of standard eth0 created by VirtualBox.
I have enabled USB controller for the gateway VM and connected the device, so a new network interface appeared in the gateway VM: “usb0”. Now I need to configure gateway to use this interface as an external network, instead of “eth0”. How do I do that?
I tried editing /etc/whonix_firewall.d/50_used.conf (almost a blind guess) – did not work.
Any help is much appreciated, thank you.
