Been chasing this for a couple days now, at first I thought it was a dhcp issue, but then I couldn't get things to work with a static IP either. Linux boxes seem to handle the issue better than Windows where IPv4 completely breaks.
Looks like the router is responding with it's MAC for every address on the subnet, all 3 addresses were unused.
