connection to www trough wifi network interface


I must connect whonix gateway with www not trough eth0 but trough wifi network interface.
In virtual box i allowed wifi card in usb device filters and Im seeing that connection from whonix gateway instance.
Now which files i should edit to change connection with www from eth0 to wlan0?

i tried to follow this topic:
forums.whonix org/t/how-to-direct-external-gateway-traffic-to-different-network-interface/7830

but i still getting message “job for tor@default.service” failed because the control process exited with error code".

This is unsupported.
