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.
