At home I have tomatousb installed on my Asus RT-N16,
i want to block all traffic from host let's say 192.168.0.100 to host 192.168.0.200. both hosts are inside local lan network.
how do i do that with iptables?
iptables -I INPUT -i br0 -o br0 -d 192.168.0.200 -s 192.168.0.100 -j DROP
but it's not working
