Hallo Raymond,

Sorry for answering a bit late but I was away for a week on a course for
Cisco routers. And there was ICMP a part of the lessons as well.
I don't know if there is a flaw in ICMP but the problem you are refering to
is the use of ICMP itself. ICMP can be compared with email: normal email
traffic is accepted, SPAM isn't. Normal ICMP traffic is acceptable but a
continous stream of ICMP commands isn't. And most of the time there are
hackers behind those streams. And that's why nowadays more and more routers
start to ban ICMP. Most firewalls don't accept it anymore at all.
Regarding the C64: ICMP is handled by software. So it is completely up to
you whether you want to handle ICMP requests or not.
