As title

How to make hosts in the same network cannot see and interact with one another by iptable rules.

for ex. 192.168.3.11 cannot interact with 192.168.3.22

And in one odd syslog ACCEPT message.

I found host A (192.168.3.11) tried to access another host B(192.168.6.13).
A is truly exists but B is not because I have none of the subnet(192.168.6.0) set in my router.

How to drop this kind of odd packets by iptalbes?

thanks.

1) Put a firewall on the host itself or put them on different sub-nets.

2) As host B does not exist, you should not be worried about it being accessed.
