Hi,
What can I do to get the router to send a "no route to host" ICMP back to the server instead of just dropping it?
if we look at the proposed solution: nothing But why not simply permit the communication?
For a router to send a no route to host ICMP message as the name implies it must lack a route to destination host. and IMHO you won't be able to do this without disrupting connectivity with internet.

Actually if you add an access-list to a cisco switch if the access-list blocks the traffic if I do not remember wrong it will send you an icmp error message.
And thats what you want right ?
But why not just redirect it to 127.0.0.1 like the article says ?
would that not be easier ?
Good luck
