A network admin wants to monitor traffic destined for host H, and has purchased a router R with monitoring software. The manager only wants traffic destined for H to pass through R. explain how to arrange forwarding to satisfy the manager.


AFAIK, I just need router to NAT the ip. Isn't that all? Why's this even a PROBLEM in the book?

Host---Router---users

When user says Host

It should hit router.
Which in turn hits host.
Kinda like proxy.

It seems like you are working to an outdated curriculum (not unusual in this industry), so a couple of phrases you want to look up are icmp redirect and policy based routing. Although it could be just a horribly written question about simple port mirroring for all we can tell from what you've pasted here.

But there are lots of other ways to send traffic from some particular host to some particular destination via some specific gasteway that isn't used by other clients to reach the same dest.

 

you're correct about icmp. this is in a topic about icmp
