Hi,

I`m absoulte newbie to netfilter, but last year I set up my debian 
firewall. I tought it`s configuration is correct, but yesterday I found 
http://audiymypc.com which shows my real ip address which I wanted to 
hide. It shows the correct address too, but it seems my real local 
address is visible on the internet somehow.

This is my configuration:
