Guys,

So... has anyone been able to verify that the problem occurs when the TTL
expires without the packet being addressed to the router?  Or is it a
requirement that the evil packet be addressed to the router?

As far as we know, the TTL has to go to 1/0 on the target  IP address.

Haven't been able to get the effect on a transit packet. 

Regards,

tom.
