So, how can I redirect for instance 443 traffic to a specific IP to the local IP address of the local server? I have tried this:

iptables -t nat -A PREROUTING -d XXX.XXX.XXX.XXX -p tcp --dport 80 -j DNAT --to YYY.YYY.YYY.YYY

I think you has to do POSTROUTING

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.
