if i do this, it does not work:
iptables -A PREROUTING -t nat -p tcp -d 65.18.193.12 --dport 15000 -j 
REDIRECT --to 127.0.0.1:15000
answer:
iptables v1.4.10: REDIRECT: Bad value for "--to-ports" option: 
"127.0.0.1:15000"
Try `iptables -h' or 'iptables --help' for more information.

how can i find out, if a programm uses tcp or udp protocoll for connection?
