This CANNOT work!
If eth0 is taken by something, you cannot assign it again by such rules, so 
all of them will fail.
Give your devices descriptive names:
eth_lan0
eth_wlan0
eth_fw0

Those won't conflict with the names that the kernel chooses, so you do not 
conflict.
This applies to whatever method you choose to change the interface name.
