Hello, I want to account all traffic from the address assigned to the linux box (including NAT, locally generated traffic), but i can't. The rule iptables -t mangle -A POSTROUTING -s 213.25.213.42 seems not to ,,catch'' NAT-ed packets, only locally generated traffic. Is there any method to ,,catch'' packets after NAT with netfilter? Best Regards, -- Piotr Kaczmarek
