Hi everyone - this is my first post to this list - so if anything is
wrong with my way of posting please tell.

And here is the question. How is it possible to nat a lokal port?

IPTABLES -t nat -A PREROUTING -p tcp -d 127.0.0.1 --destination-port 81
-j DNAT --to-destination 127.0.0.1:80

telnet localhost 80  <<< works
telnet localhost 81  <<< Connection refused
