What is it? 20 years? since the first time I was banned from NANOG for 
saying that the world would be a nicer place if EVERY true router 
refused to forward a packet whose SOURCE could not be reached from the 
port question.  (May not be stated clearly, but idea seems simple 
enough:  If the proposed ICMP message would not be routed to the port 
the packet came from, the best plan is probably to log the event and 
drop the ICMP and the rogue packet on the floor.)
