Generally, nat and broute are intended to be a configuration databases 
only, where special semantics to standard verdicts can apply, as it does 
for broute. To avoid confusion, the use of DROP in nat is not 
advised, and iptables checks for such attempts. Ebtables doesn't, but 
then again, it's the 4th-order-stepson of iptables only...
deep down below in source code, DROP just does that - drop.
