-A INPUT -j REJECT --reject-with icmp-host-prohibited
But, I think it's better to disguise the rejection as no service, rather than notice a interloper there was a service you cannot reache.
-A INPUT -p tcp -j REJECT --reject-with tcp-reset
-A INPUT -p udp -j REJECT --reject-with icmp-port-unreachable
-A INPUT -j REJECT --reject-with icmp-host-prohibited
