hmm, locally generated messages do not pass the PREROUTING AFAIK
this was why I was suggesting POSTROUTING, but...
POSTROUTING is wrong too according to the manpage for iptables

DNAT:
This target is only valid in the nat table, in the PREROUTING and OUTPUT chains, and user-defined chains which are only called from those chains.

If I read it correct, this rule should go into the OUTPUT chain.
