I have a couple of ideas on what is causing the problem, but before I speculate, I would be very curious as to what type of router this is that you are using and what operating system(s) are running on each of the three hosts. Specifically, are these Windows hosts (and version) or not? Also, what indication were you given that *all* hosts responded to the subnet broadcast ping? Were you using a sniffer, or were you just checking your arp cache?
