I do not remember for sure, but I probably moved or commented out this file back when I tested the new scheme. In case it was in place at that time, it would have contained this:

   SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="lan1"

   SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="yy:yy:yy:yy:yy:yy", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="wan0"

After my tests resulted in failure due to this bug, I restored everything back.

I can try again with current Debian testing and with removed file for sure in a couple of days.
