I have a service running on a box wich is only able to bind to 127.0.0.1 (hardcoded and I can´t get the source to change it). Since I want to use it from any other box the only way to solve that I think is to nat incoming packets to 127.0.0.1. IPTABLES -t nat -A PREROUTING -p tcp -d 172.16.172.12 -j DNAT --to-destination 127.0.0.1 and many others wich I tried don´t work. If I understood REDIRECT correctly it only changes to the local IP where the packet came in (in my situation 172.16.172.12) wich also not solves the problem. any ideas? Henry
