That's because the DNAT target does not return to the chain. The LOG target
is almost the only target I can think of which *does* return back to the
chain for further processing - all other targets are the "final outcome" for
the packet.
Put the two rules the other way round and you'll get both LOGging and
DNATting.

Antony.
