Aha! I had overlooked that, too. You want that subnet value to be the network address, but 10.0.0.1 is one of your host addresses. I don't know, however, why that is causing the behavior you are experiencing. Might be instructional to look at a network capture of the DHCP packets to see if they are doing some odd routing because they are confused.

https://lists.isc.org/mailman/listinfo/dhcp-usersShouldn't your subnet be 10.0.0.0 instead of 10.0.0.1? Simple things like that have confounded me in the past, perhaps this is one of those cases. Good luck,
Lamar
