Hi All, I am sending packet between two back to back connected machine.when I use same network (192.168.7.x) packet reach upto NF_IP_LOCAL_IN (IPTABLES INPUT) hook.It is accepted. But when I spoof ip address network(192.168.8.x) it pass NF_IP_PRE_ROUTING hook but dropped before NF_IP_LOCAL_IN hook. case 1: 192.168.7.12 --> 192.168.7.19 Accepted. case 2: 192.168.8.25 --> 192.168.7.19 Dropped. I didn't get why it dropped ? How network change effect on routing inside kernel tcp/ip stack ?
