You can't LOG and REJECT on the same line. What you have to do is place another line just above this line that looks almost identical only you replace "-j REJECT --reject-with-icmp-host-prohibited" with "-j LOG" .... So as the packet flows along down the path, it will get logged.... then continue on and get rejected.
Just do some refesher reading on Google about iptables. You should get some very good information.
