Iptables will happily redirect anything you like to localhost, but the 
kernel IP routing prohibits communications with a loopback address on a 
non loopback interface and thus will drop the packets. This is similar 
to the problem in the above thread "port forwarding through localhost", 
and the same workaround is applicable.
